چکیده

Integrating a stereo-photogrammetric robot head into a real-time system requires software solutions that rapidly resolve the stereo correspondence problem. The stereo-matcher presented in this paper uses therefore code parallelisation and was tested on three different processors with x87 and AVX. The results show that a 5mega pixels colour image can be matched in 5,55 seconds or as monochrome in 3,3

Towards Real-Time Stereo Employing Parallel Algorithms For Edge-Based And Dense Stereo Matching

Only few problems in computer vision have been investigated more vigorously than stereo. Nevertheless, the main obstacle on the way to their practical application is the excessively long computation time needed to match stereo images. This paper presents parallel algorithms for edge-based stereo suitable for depth computation. Edge-based stereo techniques produce only sparse depth maps. Thus, w...

Real time sparse and dense stereo in an early cognitive vision system using CUDA

This master’s thesis proceeds the work done in my FORK. Here we investigate how the introduction of a CUDA enabled graphics card can speed up the algorithms involved during the stereo computation of the CoViS framework. Stereo matching and reconstruction in general tend to be computationally heavy, and the support for parallel execution motivates us to transfer known algorithms to the massively...

Runtime Analysis of GPU-Based Stereo Matching

This paper elaborates on the possibility to leverage the highly parallel nature of GPUs to implement more efficient stereo matching algorithms. Different algorithms have been implemented and compared on the CPU and the GPU in order to show the speedup gained by moving the computation to the graphics card. The results were evaluated for accuracy using the test available on the Middlebury website...

Development of a Stereo Vision Measurement System for a 3D Three-Axial Pneumatic Parallel Mechanism Robot Arm

In this paper, a stereo vision 3D position measurement system for a three-axial pneumatic parallel mechanism robot arm is presented. The stereo vision 3D position measurement system aims to measure the 3D trajectories of the end-effector of the robot arm. To track the end-effector of the robot arm, the circle detection algorithm is used to detect the desired target and the SAD algorithm is used...

Stereo Vision and 3D Reconstruction on a Distributed Memory System

An important research topic in image processing is stereo vision. The objective is to compute a 3-dimensional representation of some scenery from two 2-dimensional digital images. Constructing a 3-dimensional representation involves finding pairs of pixels from the two images which correspond to the same point in space. Several stereo matching algorithms are developed to find matching pairs. Hi...
