In the paper, morphology is used to filter the image firstly, and then the Sobel edge detection operator is improved. Furthermore,the least square fitting method is introduced to polish the edge detection,which compose a new subpixel edge detection algorithm with the complete theoretical system by conjoining morphology, numerical analysing method with edge detection theory. The algorithm improves the performance of classical edge detection methods in filtering,edge locating and fitting method for precision and makes it practical in the accurately detecting field and some other fields
