Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

[0035] refer to figure 1 , a vehicle navigation system based on optical and acoustic systems, including an optical system, an acoustic system, a positioning system, a control system, and a steering mechanism.

[0036] The optical system includes one or more infrared sensors that use 3D reconstruction techniques to identify obstacles within the optical field of view.

[0037] The acoustic system includes one or more echolocation sensors that use beamforming technology to identify obstacles within the acoustic field of view.

[0038] The positioning system employs a Global Positioning System (GPS) transceiver to dynamically determine the current location of the vehicle.

[0039] The control system receives information from the optical system, acoustic system and positioning system, dynam...

Abstract

The invention discloses a carrying tool navigation system, method and equipment based on optical and acoustic systems and a readable storage medium. An optical system, an acoustic system and a positioning system are combined; the positioning system acquires the positions of the carrying tool and the target point; navigation route is further planned, because the detection distance of the optical system is far greater than that of the acoustic system, the optical system is adopted to detect a long-distance obstacle on the navigation route, the navigation route is updated according to the long-distance obstacle, meanwhile, the acoustic system is adopted to detect a short-distance obstacle of the updated navigation route, and the carrying tool is controlled to avoid the obstacle. According tothe method, an optical system and an acoustic system are combined to compensate for measurement blind areas, the defects of the acoustic system and the optical system during respective detection are overcome, a navigation route is adjusted and updated in time in the moving process of the carrying tool, obstacles are avoided accurately, and therefore the carrying tool can reach a target position more efficiently and rapidly.

Description

technical field [0001] The invention belongs to the field of vehicle navigation, in particular to a vehicle navigation system, method, device and readable storage medium based on optical and acoustic systems. Background technique [0002] Vehicles, such as drones, manned aircraft, vehicles, ships, etc., play an important role in surveillance, reconnaissance and other tasks. In situations such as low-altitude urban reconnaissance, drones may encounter fixed or moving obstacles, large and small, and the location of the obstacles is not known in advance. At present, the accuracy of laser sensors used in various obstacle detection methods is not high; the algorithm required by visual sensors requires a large amount of calculation and cannot detect transparent obstacles, and is greatly affected by the intensity of light; infrared sensors are greatly affected by the environment, and the measurement is not accurate; acoustic wave sensors The action distance is short.
