Aerial survey system based on laser radar and long-endurance unmanned aerial vehicle and automatic operation method of aerial survey system

Abstract

The invention discloses an aerial survey system based on a laser radar and a long-endurance unmanned aerial vehicle and an automatic operation method of the aerial survey system. The aerial survey system comprises an aerial survey controller, a laser radar, an orthographic camera and a high-precision combined inertial navigation unit, wherein the aerial survey controller is carried on the unmannedaerial vehicle, and the laser radar, the orthographic camera and the high-precision combined inertial navigation unit are electrically connected with the aerial survey controller; and a power supplycontrol unit supplies power to all the above components. The aerial survey controller can be in real-time communication with the data processing computer of a ground system through the communication data link of the unmanned aerial vehicle and can also be in wired communication with the data processing computer of the ground system through a network cable. The aerial survey system disclosed by theinvention is carried on an unmanned flying platform, so that the load capacity of the flying platform during aerial survey operation can be effectively reduced, and therefore, the oil consumption ofthe aerial survey operation is reduced, aerial survey operation time is prolonged, and economic benefit is improved. Due to the fact that the weight of the system is small, a small flying platform canbe selected to achieve low-altitude aerial survey operation; due to the fact that the flying height of the low-altitude aerial survey operation is low, airspace application is relatively easy; the low-altitude aerial survey operation is just slightly influenced by severe weather, so that aerial survey operation efficiency can be effectively improved.

Description

technical field [0001] The invention belongs to the field of automatic control, in particular to an aerial survey system based on laser radar and long-endurance unmanned aerial vehicle and its automatic operation method in this field. Background technique [0002] With the rapid development of laser radar, oblique photography and other technologies in recent years, aerial three-dimensional aerial survey technology has been widely used in smart cities, rail transit, power line inspection, emergency rescue and disaster relief and other aspects closely related to social life. The aerial survey system is mounted on Aircraft operations can realize rapid aerial measurement of large areas. [0003] At present, there are two main operating modes of the airborne lidar aerial survey system: 1) flying at low altitude (about 300-500 meters) to measure the spatial geographic information of the target area; Inspection of power lines. The above two operation methods have significant comm...

AI Technical Summary

Problems solved by technology

[0004] Since it is mounted on a manned flight platform, the aerial survey operation mainly depends on the on-board operation of the operator, which has the disadvantages of large flight load, high operation complexity, high personnel dependence, and the inability to carry out operations in dangerous environments
