Error distribution modeling for stereo vision system

【摘要】 In order to complete the measurement of relative position and attitude for a malfunction satellite or space debris and some other non-cooperative targets in short range,we analyze the factors that affect the measurement accuracy including the image feature extraction accuracy,the focal length calibration precision,the rotation matrix and the baseline calibration precision between two cameras,based on the principles of photogrammetry and the measurement model.The analysis results indicate that under the constraints in our design,the distance error could be controlled below0.1 m.The analysis of the error affecting factors for stereo vision measurement system will guide the system design and engineering application.更多还原
