Laser navigation lamp system for rescue vehicle in complex environment and navigation method

Abstract

The invention relates to a laser navigation lamp for a rescue vehicle in a complex environment. The laser navigation lamp comprises a bearing base, a laser range finder, microwave range finding radars, laser navigation lamps, a 3D scanning camera and a driving circuit, wherein bearing grooves are formed in the front end surface and the rear end surface of the bearing base, the laser range finder and the 3D scanning camera are embedded in the bearing grooves on the front end surface of the bearing base, the microwave range finding radars are evenly distributed on the front end faces, corresponding to the groove walls of the bearing grooves, of the bearing base along the axis of the bearing base, the laser navigation lamps are symmetrically distributed on the two sides of the bearing base, the drive circuit is embedded in the bearing grooves in the rear end face of the bearing base, and the use method comprises two steps of equipment assembly, navigation obstacle avoidance and the like.According to the laser navigation lamp system for the rescue vehicle in the complex environment and the navigation method, on one hand, the requirement of matching operation with various different vehicle equipment in various complex field environments can be effectively met, and on the other hand, long-distance and short-distance synchronous distance measurement and three-dimensional modeling recognition can be carried out on a travel path, so that the obstacle judgment and recognition precision on the travel path is effectively improved.

Description

technical field [0001] The invention relates to a vehicle navigation device, which belongs to the technical field of special rescue vehicles. Background technique [0002] At present, in the on-site rescue of disasters such as fires, earthquakes, and mudslides, disaster relief vehicles often need to use navigation equipment and obstacle avoidance equipment to plan and navigate the vehicle's running path during operation. The navigation equipment and obstacle avoidance equipment currently used are often The traditional GNSS-based satellite navigation, ranging radar and on-site cameras and other related supporting operations can meet the needs of use to a certain extent. The reliability of the equipment is relatively poor, and it is even impossible to carry out effective navigation operations; on the other hand, the current navigation and obstacle avoidance equipment in operation can only meet the requirements for planning the approximate route and for the navigation on the pa...

[0002] At present, in the on-site rescue of disasters such as fires, earthquakes, and mudslides, disaster relief vehicles often need to use navigation equipment and obstacle avoidance equipment to plan and navigate the vehicle's running path during operation. The navigation equipment and obstacle avoidance equipment currently used are often The traditional GNSS-based satellite navigation, ranging radar and on-site cameras and other related supporting operations can meet the needs of use to a certain extent. The reliability of the equipment is relatively poor, and it is even impossible to carry out effective navigation operations; on the other hand, the current navigation and obstacle avoidance equipment in operation can only meet the requirements for planning the approximate route and for the navigation on the path during the process. Obstacles perform simple ranging operations, but it is impossible to accurately plan and limit the range of travel paths, and at the same time, it is impossible to accurately judge the structure and volume of path obstacles, resulting in the inability to judge the passability of obstacles during vehicle operation , it is very easy to damage the vehicle due to factors such as excessive obstacles, which seriously affects the stability and reliability of the vehicle operation
