Ground topography scanning device and method based on unmanned aerial vehicle and solid-state radar

Abstract

The invention discloses a ground topography scanning device and method based on an unmanned aerial vehicle and a solid-state radar. The device comprises an unmanned aerial vehicle platform, a controller, the solid-state radar, a satellite and an inertial navigation system, wherein the solid-state radar, the satellite and the inertial navigation system are hung below the unmanned aerial vehicle. The solid-state laser radar comprises a sensor and a data processing unit, the sensor scans the ground and obtains a scanned image, and then the scanned image is processed by a data processing unit to form position data of a scanned area of the ground; the controller makes the unmanned aerial vehicle perform flight operation according to a preset route and acquires positioning attitude data of the satellite and the inertial navigation system in real time; and the controller performs fusion processing on the position data and the positioning attitude data to obtain ground topography data. In theinvention, the solid-state radar is combined with the unmanned aerial vehicle platform, and characteristics that the solid-state laser radar does not need mechanical rotary scanning, and has a compactstructure and good vibration resistance are utilized so that scanning efficiency is improved, flight energy consumption is reduced, and overall suspension time and voyage are improved.
