Embodiment 1
[0036] The present invention provides a technical solution: a remote sensing detection method for ecological restoration of abandoned karst mines, comprising the following steps:
[0037] S1, select a preset number of checkpoints;
[0038] S2, according to the remote sensing mapping technology, compare the ground object data change map with the topographic map database, and judge whether the new map needs to be updated in whole or in part;
[0039] S3, according to the coordinates obtained by remote sensing mapping, the object square adjustment value of the checkpoint is obtained through the least squares adjustment;
[0040] S4, calculating the residual error between the object space coordinates of the inspection point and the object space adjustment value in the X and Y directions;
[0041] S5, judging whether the residual error follows a standard normal distribution, if so, judging that there is no systematic error, and if not, judging that there is a systematic error;
