Abstract

The invention discloses an an airborne laser scanner device. The airborne laser scanner device at least comprises an unmanned aerial vehicle, fixing plates, an angle adjusting device and a laser scanner; a supporting frame is arranged below the unmanned aerial vehicle; the two fixing plates with symmetrical positions are fixed on the supporting frame; and the angle adjusting device is arranged between the two fixing plates; the angle adjusting device at least comprises a containing cavity formed in one of the fixing plates; a moving plate capable of moving in the vertical direction is arranged in the containing cavity; the front face of the moving plate is connected with a driving assembly; two rotating pieces are hinged to the inner side of the moving plate; one end of one rotating piece is rotationally connected with a clamping plate, the other end of the clamping plate is hinged to the other fixing plate; and a laser scanner is fixed between the two clamping plates. The airborne laser scanner device is simple in structure and novel in shape; and the angle of the laser scanner is adjusted by ingeniously adopting a mode similar to angle adjustment of a hinge on a hinge window, so that the angle of the laser scanner can be adjusted in a working process.

Description

technical field [0001] The invention relates to the technical field of three-dimensional scanning, in particular to an airborne laser scanner device. Background technique [0002] In the prior art, airborne laser radar (Light Detection And Ranging, LIDAR) uses laser for echo ranging and orientation, and identifies targets through information such as position, radial velocity, and object reflection characteristics. It embodies special transmitting, scanning, receiving and signal processing techniques. Airborne lidar technology originated from the laser ranging technology in traditional engineering surveying. It is the product of the combination of traditional radar technology and modern laser technology. It is an emerging technology in the field of remote sensing measurement. [0003] However, the existing laser scanners are more fixed structures than UAVs, and the angle cannot be adjusted during the work process, thereby reducing the use effect of the laser scanner. Therefo...
