摘　　要：几何图形的识别是计算机视觉领域的重要任务之一,为了准确识别目标,针对矩检测问题,提出了一种基于链码跟踪的检测算法。该算法用改进的链码跟踪方法来求得候选矩形的轮廓,将轮廓分段后由直线拟和求得候选矩形的数值解,并通过证据收集来确认真矩形以保证检测精度。数值实验结果表明:该算法具有鲁棒性较好、精度较高、速度较快的优点。This paper proposes a algorithm which is based on chain-code tracking for the rectangle detection.It uses the method of chain-code tracing algorithm which is improved to get the contour of the candidate rectangle.After that it divides this contour into segments and evaluated the numerical solution of the candidate rectangle by linear fitting.Then it ensures accuracy of detection by gathering the really evidence.Numerical experiment results show that this algorithm has the better robustness,the higher precision and the faster speed.
