Research on Image Measuring method based on monocular camera and Ruler

摘要

Start from the image edge detection, the papers analyze the edge detection principle and some commonly edge detection operator, and on basis of it, we introduced wavelet transform, and proposed an improved multi-scale edge detection algorithm, then new edge thinning algorithm are proposed for the particularity of the edge, finally picking up the features through the mark point target, calculate the final distance results. The results also prove that the proposed scheme is effective, adaptive and accurate, and meets the requirements of real industrial production.
