Intelligent laser ranging device and self-resetting method thereof

The invention relates to the technical field of laser ranging, in particular to an intelligent laser ranging device and a self-resetting method thereof. One side of the upper platform is connected with the back plate through a rotating shaft, and the upper platform can rotate up and down along the rotating shaft in a single degree of freedom manner; the rotary table is arranged on one side, far away from the back plate, of the upper platform, a rigid rod is arranged at the tail end of the rotary table, and the rotary table is used for arranging a laser range finder. Compared with the prior art, the method has the advantages that the problem that in the tunnel convergence automatic monitoring scene, after laser ranging point position deviation caused by tunnel external environment change is solved, the laser light spot is automatically reset and automatically returns to the preset measuring position under the non-manual intervention condition, the long-term manual calibration mode is replaced, and the accuracy
