Abstract

The invention relates to the field of unmanned aerial vehicle surveying and mapping, and provides a surveying and mapping method for automatically scanning a road by an airborne three-dimensional laser scanner in order to solve the problem of crash caused by collision when an unmanned aerial vehicle performs automatic return flight in existing unmanned aerial vehicle surveying and mapping, and the surveying and mapping method comprises the following steps: a flight step: the unmanned aerial vehicle flies according to a preset flight route; a scanning step: a scanner carried by the unmanned aerial vehicle scans the scenery in the flight route and obtains the three-dimensional coordinates of the surface of a measured object, and the obtained three-dimensional coordinates are processed to obtain a surveying and mapping image; the method further comprises the protection step that when the unmanned aerial vehicle is collided, a triggering piece of a protection system on the unmanned aerial vehicle collides with a collision object, the triggering piece triggers a buffering mechanism of the protection system to be started, and the buffering mechanism sprays air in the flight direction of the unmanned aerial vehicle and marks the collision object.

Description

Technical field [0001] The present invention relates to the field of drone mapping, and is specifically a surveying method for automatic scanning roads for airborne 3D laser scanners. Background technique [0002] Three-dimensional scan is a high-tech of collective light, machine, electricity, and computer technology, mainly for scanning object space profile and structures to obtain spatial coordinates of the surface of the object. The three-dimensional laser scanner can utilize three-dimensional laser scanning techniques, and quickly obtain three-dimensional coordinate data of the surface of the subject surface to obtain high-precision high resolution digital terrain models. Therefore, the target area is currently scanned to obtain a three-dimensional terrain in the target area when the aerial photograph is used. [0003] Since the life-fire time of the drone is usually not too long, it is necessary to operate the personnel to pay attention to the remaining power of the drone in...
