Abstract

The invention relates to a laser radar and provides an airborne miniature laser radar three-dimensional plotting apparatus. The apparatus comprises a laser scanner, a high-resolution digital camera, alaser scanner and a shell. The laser scanner is partially installed on and is fixedly arranged on one external surface of the shell. The high-resolution digital camera is arranged on another externalsurface of the shell. A partial structure of the laser scanner, an embedded computer and an inertial measurement instrument are arranged in the shell. A global satellite positioning system and a storage module are arranged in the embedded computer. In the invention, the laser scanner and the digital camera are located at two opposite ends of an outer side of the shell respectively; the inertial measurement instrument, the partial structure of the laser scanner, the embedded computer and the like are arranged in the shell, and an integrated level is high; an integral structure of the plottingapparatus is guaranteed to be beautiful and an aircraft is convenient to carry the apparatus; advantages that an application is flexible, three-dimensional measurement precision is high, a topographyunder vegetations is acquired, autonomous navigation and height variation flight are achieved and so on; and the apparatus can be used for high-precision three-dimensional topography plotting of hillsand mountain areas.

Description

technical field [0001] The invention belongs to the field of remote sensing surveying and mapping, in particular to an airborne miniature laser radar three-dimensional surveying and mapping device.
