Embodiment Construction
[0041] The specific embodiment of the present invention is as shown in the accompanying drawings. Taking the edge correction between four adjacent orthophotos with a certain overlapping adjacent area as an example (as shown in Figure 2), the specific steps are:
[0042] 1. Obtain the point with the same name
[0043] Using the image gray-scale cross-correlation matching technology based on object space constraints to automatically match the same-named points in the adjacent areas of all images, obtain the same-named points, and ensure that any identical-named point in the adjacent area has an observation on all observed images at this position value;
[0044] 2. Use the same-name points matched in step 1 to construct a triangular network
[0045] 3. For each point with the same name, calculate the reference object space coordinates of the point with the same name according to the observed object space coordinates of the same point on each image. Methods as below:
[0046] ...
