Target measurement has always been a hot topic in computer vision. Image measurement system can realize accurate measurement without contact. In this paper, a target distance and dimension measurement system based on monocular camera is designed, firstly, the imaging principle of monocular camera and the measuring theory based on similar triangle are introduced. Then, the similarity measurement algorithm based on Gaussian filtering and canny edge detection and implementation steps were analysed and summarized.
