摘　　要：由于在单一尺度空间中,边缘检测算子不可能正确地检测出所有满足实际需要的边缘,提出B-spline算子与Canny算子结合的边缘检测算法,首先用B-spline算子对图像进行多尺度空间处理,然后用Canny算子进行边缘检测,给出了尺度空间的计算过程和实例,并以实拍复杂背景条件下红外机场跑道为边缘检测实验对象,通过实验,将该算法与经典算法相比较,证实该算法在检测物体弱边缘、消除边缘误检测及提高算法效率方面具有优势。In single-scale space,the edge detection operator could not correctly test all edges to meet the actual require-ments,an algorithm of weak edge detection based on B-spline operator combining with Canny operator is proposed. The image is processed in multi-scale space with B-spline operator,the Canny operator is applied to edge detection. The calculation process and examples of scale space is provided,and the infrared airport runway under complex background as the edge detection experi-ments,the results indicate that the proposed algorithm has advantages in detecting weak edges of objects,eliminating false edge detection and improving the efficiency of algorithm,compared to the traditional edge detection algorithm.
