摘要
Abstract
Prism-based single-lens stereo vision system has features of high integration,low power,easy assembly,etc.However,external prism can cause irregular image distortion,affecting image quality.First,we reduce image noise and enhance image border by bilateral filter to improve the accuracy of the feature point detection effectively.Then we combine the perspective projection of the linear,cross ratio consistency and convergence of the vanishing point to propose an improved adaptive distortion correction algorithm.Finally,distortion correction could be achieved by offsetting before and after correction feature point without distortion model and parameters.The experiment compared the multiple sets of image feature extraction and distortion correction results and different methods for correcting irregular distortion correction effect generated in the system,the results show the robustness and accuracy of the algorithm,and it improves the accuracy of robotic vision system.关键词
