B Pins 13 and 14 can be either directly connected to the ground or connected to the ground using a retractable device. The DisplayPort A Mini DisplayPort receptacle (centre) with Thunderbolt 3 port (left) and power input (right) DisplayPort (DP) is a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). The interface is mainly used to connect the video source to a display device, such as a computer monitor, and it can also carry audio, USB and other forms of data. DisplayPort was designed to replace VGA, FPD-Link and digital visual interface (DVI). The back interface is compatible with others such as HDMI and DVI, using active or passive adapters. DisplayPort review is the first display interface to rely on packaged data, a form of digital digital in technologies such as Ethernet, USB and PCI Express. This allows the use of internal and external display connections, and unlike outdated standards that transmit an hour-long signal with each output, the DisplayPort protocol is based on small data packets known as micro-packs that can insert a clock signal into the data stream. This allows you to get a higher resolution using fewer contacts. Using data packets also makes DisplayPort possible to be exuding, which means that additional features can be added over time without significant changes to the physical interface. DisplayPort can be used to transmit audio and video at the same time, although each one is optional and can be streamed without the other. The path of the video signal can range from six to sixteen bits per color channel, and the audio path can have up to eight channels of 24-bit, 192 kHz PCM audio that is not compressed. A two-direction, semi-duplex support channel carries device management and device management data for the main link, such as VESA EDID, MCCS, and DPMS standards. In addition, the interface is capable of carrying two-direction USB signals. DisplayPort uses an LVDS signal protocol that is not compatible with DVI or HDMI. However, dual-mode Ports DisplayPort are designed to transmit the DVI or HDMI protocol with a single link (TMDS) through the interface using an external passive adapter. This adapter provides compatibility mode and converts the signal from 3.3 volts to 5 volts. Analog VGA/YPbPr and two-edge DVI require an active powered adapter for compatibility and does not rely on dual mode. Active VGA adapters are powered directly by the DisplayPort connector, while active dual-link DVI adapters typically rely on an external power source such as USB. Versions 1.0 to 1.1 The first version, 1.0, was approved by VESA on May 3, 2006. Version 1.1 was ratified on April 2, 2007, and version 1.1a was ratified on January 11, 2008. DisplayPort 1.0-1.1a allows a maximum bandwidth of 10.8 Gbit/s (8.64 Gbit/s data speed) over the standard 4-band main link. DisplayPort cables up to 2 metres long are required to maintain a full capacity of 10.8 Gbps. DisplayPort 1.1 allows devices to implement alternative layers of communication, such as fiber optic, allowing for much longer reach between the source and the display without signal degradation, although alternative implementations are not standardized. It also includes HDCP in addition to DisplayPort Content Protection (DPCP). DisplayPort 1.1a is free to download from the VESA website. Version 1.2 DisplayPort 1.2 was introduced on January 7, 2010. The most significant improvement in the new version is the doubling of bandwidth up to 17.28 Gbps in High Bit Rate 2 (HBR2) mode, allowing you to increase resolution, higher upgrade speeds and greater color depth. Other improvements include yourself independent video streams (multi-stream transport) called Multi-Stream Transport, stereoscopic 3D tools, AUX bandwidth increase (from 1 Mbps to 720 Mbps), more color spaces including xvYCC, scRGB and Adobe RGB 1998, and Global Time Code (GTC) to synchronize audio/video. In addition, Apple Inc.'s Mini DisplayPort connector, which is much smaller and is designed for laptops and other smaller devices, is compatible with the new standard. Version 1.2a DisplayPort 1.2a was released in January 2013 and may additionally include adaptive VESA synchronization. AmD FreeSync uses DisplayPort Adaptive-Sync to work. FreeSync was first demonstrated at CES 2014 on the Toshiba Satellite laptop, using the Panel-Self-Refresh (PSR) feature from Embedded DisplayPort, and after an offer from AMD, VESA later adapted the Panel-Self-Refresh feature for use in standalone displays and added it as an additional feature of the main DisplayPort standard called Adaptive-Sync Because it is a non-binding feature, Adaptive-Sync support is not required for display to be DisplayPort 1.2a compatible. 1.3 Version 1.3 DisplayPort was approved on September 15, 2014. This standard increases the total transmission capacity to 32.4 Gbps with the new HBR3 mode from 8.1 Gbps per lane (according to 5.4 Gbps HBR2 in version 1.2), for total data bandwidth of 25.92 Gbit/s after factoring in 8b/10b encoding overheads. This bandwidth is enough for a 4K UHD display (3840 × 2160) at 120 Hz with 24 bits / px RGB colors, 5K display (5120 × 2880) at 60 Hz with 30 bits / px RGB color, or 8K UHD display (7680 × 4320) at 30Hz with 24 bits / px RGB color. Using Multi-Stream Transport (MST), DisplayPort can control two 4K UHD (3840 × 2160) displays at 60 Hz or up to four W'HXGA displays (2560 × 1600) at 60 Hz with a 24-bit/px RGB color. The new standard includes mandatory dual mode for DVI and HDMI adapters, introduction of HDMI 2.0 and HDCP 2.2 content protection. The Thunderbolt 3 connection standard was originally supposed to include DisplayPort 1.3, but the final release ended with only version 1.2. VeSA adaptive synchronization in 1.3 DisplayPort remains an additional part of the specification. Version 1.4 displayPort was published on March 1, 2016. The new transmission modes are not defined, so HBR3 (32.4 Gbit/s) presented in version 1.3 is still the most affordable mode. DisplayPort 1.4 adds support for compression display flow 1.2 (DSC), Correction errors forward, HDR10 metadata defined in CTA-861.3, including static and dynamic metadata and Rec color space. 2020, for HDMI compatibility, and maximum number of stationary audio channels of audio channels DSC is a visually no loss method of coding with a compression ratio of up to 3:1. Using HBR3 DSC, DisplayPort 1.4 can support 8K UHD (7680 × 4320) at 60Hz or 4K UHD (3840 × 2160) at 120 Hz with 30 bit/px RGB and HDR. 4K by 60 Hz 30 bits / px RGB/ HDR can be achieved without the need for DSC. On displays that do not support DSC, maximum limits remain unchanged from DisplayPort 1.3 (4K 120 Hz, 5K 60 Hz, 8K 30Hz). Version 1.4a DisplayPort 1.4a was published in April 2018. VESA has not made an official press release for this version. It updated the DSC DisplayPort implementation from DSC 1.2 to 1.2a. According to a roadmap published by VESA in September 2016, the new version of DisplayPort was to be launched in early 2017. This would improve the communication speed from 8.1 to 10.0 Gbps, which is 24% more.

Markus Rupp 2 So far we did only this… This is an eye-pad not an IPad Binocular vision • Binocular vision is vision in which both eyes are used together. The word binocular comes from two Latin roots, bini for double, and oculus for eye.[1] Having two eyes confers at least four advantages over having one. First, it gives a creature a spare eye in case one is damaged. Second, it gives a wider field of view. For example, humans have a maximum horizontal field of view of approximately 200 degrees with two eyes, approximately 120 degrees of which makes up the binocular field of view (seen by both eyes) flanked by two uniocular fields (seen by only one eye) of approximately 40 degrees. [2] Third, it gives binocular summation in which the ability to detect faint objects is enhanced.[3] Fourth it can give stereopsis in which parallax provided by the two eyes' different positions on the head give precise depth perception.[4] Such binocular vision is usually accompanied by singleness of vision or binocular fusion, in which a single image is seen despite each eye's having its own image of any object.[4] Binocular vision • Some animals, usually prey animals, have their two eyes positioned on opposite sides of their heads to give the widest possible field of view.

It is available to view only. This item is subject to copyright. CAPTURING OF 3D CONTENT USING A SINGLE APERTURE CAMERA By Juan Carlos Jácome Fernández A thesis submitted to the University of Bedfordshire in partial fulfilment of the requirements for the degree of Doctor of Philosophy October 2017 Abstract Integral imaging has recently re-emerged as an alternative to current 3D capturing systems, providing post-production refocusing capabilities and reducing the complexity of 3D capturing systems. One of the main drawbacks of conventional plenoptic 1 integral imaging systems is the implementation of a single custom made microlens array which has a fixed focal length and a high cost/low scalability associated with. This thesis demonstrates a variable focal length microlens arrays system, which can flexibly operate within a range of various focal lengths, increase the cost-effectiveness of the integral imaging system and offers the opportunity to manipulate the main camera optical parameters without modifying the objective lens settings. To validate the proposed concept, a custom-made integral imaging camera system was designed and built (IMPERX 4K system). Based on the results obtained from two initial optical simulations, software simulation and mathematical model; the suitable microlens arrays were acquired, and several experiments were performed to establish the feasibility of a variable focal length microlens arrays system. The results obtained show the proposed system performed as expected. The variable focal length system represents an ideal method to control microlens focal length, as it offers a higher microlens count, without a dedicated electronic system, whose performance is not susceptible to temperature-pressure changes and can operate in real-time as it does not require downtimes to re-adjust.

  • Proximal Monitoring in Landscape Environments

This thesis contains no material which has been accepted for the award of any other degree or diploma in any university. Shuqi Ng March 2017 ABSTRACT With the implementation of the initiatives in reducing emissions from deforestation and forest degradation (REDD), the accurate determination of the spatio-temporal variation of carbon stocks is crucial. Woody vegetation is one of the more noteworthy carbon storage pools. However, ever-changing forest inventory makes it difficult for countries to accurately measure woody biomass and by extension, predict carbon stocks. Although the most accurate mensuration of biomass is to harvest a tree, the method is destructive and obstructs the REDD initiative. Non- destructive methods use dendrometric measurements that have been obtained from non-contact, remote sensing technologies to estimate biomass derived from allometric models. The commodity stereo-camera is an alternate consideration to remote sensing technologies currently used such as terrestrial laser scanning (TLS), which requires specialized equipment and some expertise in using the equipment. Improving technologies and software has enabled the photogrammetric measurements of objects to be reasonably accurate comparative to TLS. As a more mobile and cost-effective equipment, it also addresses some of the issues in using laser technology. In photogrammetric measurement, the application of spatial scale to the model is critical for accurate distance and volume estimates (Miller (2015)).

Always in motion is the future Yoda iv Sammanfattning De senaste åren har kameraprototyper som kan fånga tredimensionella (3D) bilder presenterats, baserade på 3D-tekniken Integral Imaging (II). När dessa II-bilder be- traktas på en 3D-skärm, delger de både ett djup och ett innehåll som på ett realistiskt sätt ändrar perspektiv när tittaren ändrar sin betraktningsposition. Avhandlingen koncentrerar sig på tre hämmande faktorer gällande II-bilder. För det första finns det en mycket begränsad allmän tillgång till II-bilder för jämförande forskning och utveckling av kodningsmetoder. Det finns heller inga objektiva kvali- tetsmått som uttryckligen mäter distorsion med avseende på II-bildens egenskaper: djup och betraktningsvinkelberoende. Slutligen uppnår nuvarande standarder för bildkodning låg kodningseffektivitet när de appliceras på II-bilder. En metod baserad på datorrendrering har utvecklats som tillåter produktion av olika typer av II-bilder. En II-kameramodell ingår som bas, kombinerad med ett scen- beskrivningsspråk som möjligör att godtydligt komplexa virtuella scener definieras. Ljustransporten inom scenen och fram till II-kameran simuleras med strålföljning och geometrisk optik. Den presenterade metoden används för att skapa ett antal II- kameramodeller, scendefinitioner och II-bilder.

  • Generation of 3-D Synthetic Autostereoscopic Integral Images Using Computer Simulated Cameras
    GENERATION OF 3-D SYNTHETIC AUTOSTEREOSCOPIC INTEGRAL IMAGES USING COMPUTER SIMULATED CAMERAS A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy By Shafik Salih Electronic and Computer Engineering School of Engineering and Design Brunel University March 2014 Abstract ________________________________________________________ Production of artificial Three-Dimension (3-D) images was the aim of many researches over hundreds of years. 3-D images are the images that create sense of depth when viewing them. 3-D images are closer to the real world scenes than 2-D images due to the 3-D effect or the sense of depth the 3-D images provide. Sense of depth can be caused by binocular cues including convergence and parallax. Convergence is created by the difference between the angles of the left eye and the right eye viewing axes. Parallax is the effect of viewing with one eye a view of the scene that is inherently shifted to the view seen by the other eye. Several techniques have targeted the creation of 3-D images with the mentioned cues. The technique is preferred when it is able to create 3-D images so that the viewer can view these images without wearing special glasses and the occurrence of viewer fatigue. Integral photography that was invented in 1908 is able to meet the previous requirements. Based on integral photography, several techniques, research and studies have been published. The purposes of this thesis include the computer simulation of flexible integral photography systems, the computer generation of good quality 3-D static and animated integral images using the simulated systems, optimising the generation process to be more accurate, less expensive, more effective, and faster, and producing a portable specialist software tool to achieve these targets.

  • A Uav-Based Low-Cost Stereo Camera System for Archaeological Surveys - Experiences from Doliche (Turkey)
    International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XL-1/W2, 2013 UAV-g2013, 4 – 6 September 2013, Rostock, Germany A UAV-BASED LOW-COST STEREO CAMERA SYSTEM FOR ARCHAEOLOGICAL SURVEYS - EXPERIENCES FROM DOLICHE (TURKEY) K. Haubeck a, T. Prinz b a Institute of Geography, Westfalian Wilhelms-University Münster, Germany – [email protected] b Institute for Geoinformatics, Westfalian Wilhelms-University Münster, Germany – [email protected] KEY WORDS: Archaeology, Application, DEM/DTM, Orthoimage, Close Range, UAV, Stereoscopic ABSTRACT: The use of Unmanned Aerial Vehicles (UAVs) for surveying archaeological sites is becoming more and more common due to their advantages in rapidity of data acquisition, cost-efficiency and flexibility. One possible usage is the documentation and visualization of historic geo-structures and -objects using UAV-attached digital small frame cameras. These monoscopic cameras offer the possibility to obtain close-range aerial photographs, but – under the condition that an accurate nadir-waypoint flight is not possible due to choppy or windy weather conditions – at the same time implicate the problem that two single aerial images not always meet the required overlap to use them for 3D photogrammetric purposes. In this paper, we present an attempt to replace the monoscopic camera with a calibrated low-cost stereo camera that takes two pictures from a slightly different angle at the same time. Our results show that such a geometrically predefined stereo image pair can be used for photogrammetric purposes e.g. the creation of digital terrain models (DTMs) and orthophotos or the 3D extraction of single geo-objects.
