Claim 4:
5. The method for automatically identifying south troughs by Laplace operation according to claim 4, wherein a specific implementation mode of S8 is as follows:
S8-1: connecting the northernmost point P and the southernmost point Q in all target endpoints to solve a midpoint M;
S8-2: making a horizontal line through the midpoint M, and taking a point N on a right side of the point M on the horizontal line, i.e., in an operating front of the trough line; and
S8-3: letting a distance |MN| between the point M and the point N be ⅕ of a distance |PQ| between the point P and the point Q to obtain an optimal form of the target trough line, so as to obtain the adjusted trough line.
