Claim 2:
3. The stereophotogrammetric method based on binocular vision according to claim 1, wherein for the cost aggregation of the S3, using the minimum spanning tree to regard the image as a graph of a four-connected region, defining the weight value of the edge formed by the two pixel points as the gray difference of the pixel points, traversing the minimum spanning tree by bottom-up and top-down methods to acquire the minimum spanning tree aggregation cost; and then using the scanning line optimization aggregation strategy from different directions of the image sequentially to determine the aggregation cost of the current pixel by the aggregation cost of the previous pixel, and finally, acquiring the optimal aggregation cost of the original size image by using the aggregation cost of images of each size.
