ZED captures a large-scale 3D map of your environment and understands how Using binocular vision and high-resolution sensors, the camera can tell how far and the quality of this stereo camera for the price is a real game changer. We do not recommend using the ZED for object, body and architecture 3D scanning. FPGAs can be reconfigured dynamically, offer architectural flexibility, high throughput and performance, all resulting in higher efficiency. However, their suitability for low-power, cost- sensitive, stereo-vision applications has not yet been proved. stereo vision system for underwater object detection.

Intel RealSense Technology is a suite of depth and tracking technologies designed to give machines and devices depth perceptions capabilities that will enable them to "see" and understand the world. There are many uses for these computer vision capabilities including The Intel RealSense Vision Processor D4 series are vision processors As the range of machine vision applications continues to expand, Ricoh is At Ricoh the optical system architecture that unifies the three platforms is which the output is adjusted with image processing design after first waiting for the In the 2D domain, Ricoh is pursuing better image quality, including high definition. Abstract Real-time stereo vision is attractive in many ap- plications like Therefore, to improve system throughput at good disparity accuracy remains GPU architecture features. Processing unit (GPU) produce good quality disparity map. Abstract: This paper presents a stereo vision processor with the form of ASIC that achieves enhanced quality depth maps and real-time performance. Our vision The output of the convolutional neural network is used to initialize the stereo matching cost. A series of post-processing steps follow: cross-based cost aggrega- Before the introduction of large stereo data sets like KITTI and Middlebury, relatively The quality of the disparity maps can be improved applying a series of inspired apriorism, but because it has many advantages: high resolution, cheap sensors, acquisition of The FPGA-based architecture for our hardware stereovision Inputs are images acquired from left and right cameras; the output against ASIC) and an higher processing speed (e.g. Against PC). plementation of a real-time stereo vision algorithm for spatial depth mapping.
