Abstract

The invention relates to the technical field of unmanned aerial vehicle surveying and mapping, and particularly discloses an unmanned aerial vehicle ground-imitating flight device based on a laser radar. The unmanned aerial vehicle comprises an unmanned aerial vehicle body, a high-definition camera and a laser radar, a control module is arranged on the upper surface of the unmanned aerial vehiclebody, a landing frame is connected to the lower surface of the unmanned aerial vehicle body, an upper connecting plate is connected to the lower surface of the unmanned aerial vehicle body in the middle of the landing frame, multiple round holes are evenly formed in the upper surface of the upper connecting plate, and sliding rods are inserted into the round holes; according to the unmanned aerialvehicle ground-imitating flight device based on the laser radar, the flight height of the unmanned aerial vehicle can be detected in a high-precision mode at any time through the laser radar, and then the flight height of the unmanned aerial vehicle is adjusted in real time through the control module, so that the high-definition camera of the unmanned aerial vehicle keeps a stable height with theterrain surface during surveying and mapping; Therefore, the fixed overlapping degree of the photos is ensured, and the aerial photogrammetry precision is ensured; compared with an existing unmannedaerial vehicle surveying and mapping device, thethe unmanned aerial vehicle ground-imitating flight device is better in surveying and mapping effect.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle surveying and mapping, and specifically discloses a ground imitation flight device for an unmanned aerial vehicle based on laser radar. Background technique [0002] According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft.
