摘要
选择恰当的边缘检测算法是提高影像测量系统测量精度的关键。文章对比分析了传统的边缘检测算子、canny算子的优缺点。在理论分析的基础上,结合实际的测量结果,提出了中心B样条边缘检测算法,该算法在影像测量系统中表现出良好的抗噪声干扰,并且综合性能也优于其它算法。
An appropriate edge detection algorithm plays crucial role in improving the accuracy of video measuring system. This paper analyzes the advantages and disadvantages of the traditional edge detector and canny edge detector. Based on the theoretical analysis, we propose a center B - spline edge detection algorithm. This algorithm performs well on robustness to noise in the video measuring system. The practical measuring results show that its performance is better than others.
