Abstract
Disclosed is a stereophotogrammetric method based on binocular vision, including the following steps: image acquisition, image correction and stereo matching are performed; cost matching and cost aggregation are performed on images of different sizes after correction; image segmentation is performed on the corrected image to determine edge pixel points of the object to be measured; and a pixel distance at an edge of the object to be measured is calculated to measure the size of the object. The method of the present invention enhances the matching accuracy of contour pixels of the object to be measured and improves the measurement accuracy.
