Distance measurement method, vehicle operation control method and control system

Abstract

The invention provides a distance measurement method, a vehicle operation control method and a control system, and the distance measurement method comprises the steps: obtaining the real-time coordinates of an operation vehicle through a satellite positioning instrument, and calculating the real-time coordinates of two cameras fixed at the front end of the operation vehicle; enabling the two cameras to capture the same target point P on the operation line at the same time; and performing calculating by using the visual angle and the real-time coordinate of the camera and the coordinate of thetarget point P to obtain the distance from the operating vehicle to the operating line. The control method comprises the steps that two cameras are adopted to automatically identify an operation line;the distance from the operation vehicle to the operation line is obtained in real time by adopting the method; and the driving direction of the operation vehicle is adjusted in real time according to the obtained distance. The system comprises two cameras, a satellite positioning instrument and a processor. According to the invention, the distance from the operation vehicle to the operation lineis acquired in real time by combining the satellite positioning system and the double cameras, so that the vehicle can be controlled to automatically run along the operation line more accurately.

Description

technical field [0001] The invention relates to the field of automatic control of work vehicles, in particular to a distance measuring method for obtaining the distance from a work vehicle to a work line in real time, and to a vehicle operation control method and a vehicle operation control system using the distance measurement method. Background technique [0002] Traditional work vehicles, such as lawn mowers, are operated manually, which takes a lot of manpower and time. With the development of computer technology and satellite positioning technology, automated operating vehicles have emerged. [0003] Some existing work vehicles are equipped with a satellite positioning device, which can automatically record the driving track and guide the working vehicle to automatically drive along the driving track through the satellite positioning device. However, there are still the following defects: 1. It is necessary to manually drive once to generate the driving trajectory. 2. ...

AI Technical Summary

Problems solved by technology

However, there are still the following defects: 1. It is necessary to manually drive once to generate the driving trajectory. 2. The trajectory will be recorded every time driving. As the recorded trajectory increases, the system cache data will become larger. After a certain level, the system will be damaged. Stuck and stopped

However, this solution still has the following defects: the distance from the vehicle to the production line cannot be automatically measured, so the control accuracy is not high
