[0049] see in conjunction Figure 1 to Figure 5 , the present embodiment provides a vehicle direct navigation method, comprising the following steps:

[0050] S1: the word-line laser 111 emits a word-line laser toward the traveling direction of the vehicle 170 .

[0051]Specifically, a word-line laser 111 is installed on the line laser emitting mechanism 110, further, a word-line laser 111 is installed on the laser bracket 113, and the laser bracket 113 is fixedly arranged at a reference point, so that the one-word line laser 111 can move along the A word line of laser light is emitted in the same constant direction.

[0052] Before the vehicle 170 runs, adjust the position and angle of the line laser 111 according to the straight path that the vehicle 170 needs to walk, so that the projection of the line laser emitted by the line laser 111 on the driving plane of the vehicle 170 coincides with the prescribed walking path. Specifically, to adjust the position and angle of th...

Abstract

The invention provides a vehicle straight run navigation method and a vehicle straight run navigation device and belongs to the technical field of vehicle navigation. The vehicle straight run navigation device comprises a line laser emitting mechanism which is used for installing a line laser and emitting line laser, a line laser receiving mechanism which is used for installing a line laser receiving plate and receiving the line laser, a visual recognition mechanism which is used for photographing the laser received by the line laser receiving plate through a camera so as to acquire an image and performing recognition in the system, and a vehicle which adjusts a running direction based on the recognition result of the visual recognition mechanism. Compared with the prior art, the vehicle straight run navigation device provided by the invention can make the vehicle accurately run along a straight line, has high navigation precision, is not affected by the space of a site, and can be used for both fixed sites and unfixed sites.

Description

technical field [0001] The invention relates to the technical field of vehicle navigation, in particular to a vehicle direct navigation method and a vehicle direct navigation device. Background technique [0002] Autonomous vehicles and navigation methods have become a research hotspot in the field of industrial automation. In the fields of logistics and warehousing, autonomous vehicles are increasingly used in cargo handling, material transportation, loading and unloading, such as AGV and RGV. However, in some application scenarios, the driving site of the autonomous vehicle is not fixed. For example, when using a loading machine to load vehicles in different truck compartments, the autonomous vehicle needs to walk along the centerline of the compartment in different compartments each time. , and requires high walking accuracy. In this application scenario, traditional magnetic navigation, lidar navigation and other methods are difficult to use. Contents of the inventio...
