Problems solved by technology

[0005] Since the existing navigation scheme cannot be applied to this scene to select the optimal transportation route, and the fuel consumption of the truck is very high, the fuel consumption of the loading and transportation of the goods is relatively high
[0006] Currently, no navigation method has been proposed that is suitable for areas with no paths and dynamically changing obstacles in them

Embodiment Construction

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The core idea of ​​the present invention is: on the one hand, the server side needs to maintain the location information of the obstacle-occupied area in the field in real time, so that the terminal device can use the latest location information of the obstacle-occupied area to generate a navigation path; on the other hand, the terminal The device needs to divide the coverage area corresponding to the site into a grid according to the size of the current vehicle to be navigated, so that the terminal device can accurately determine the free area in the site based on the position information of the above-mentioned obstacle occupied area, and make full use of the free area to generate Navigation path to improve the accuracy of navigati...

Abstract

The invention discloses a navigation method. The navigation method comprises the steps of maintaining, by a server, positioning information of a region occupied by an obstacle in a designated field inreal time; when a terminal device needs path navigation in the field, dividing a covered area of the filed into a plurality of lattices according to the size of a vehicle needing navigation, and determining an obstacle occupation state of an area corresponding to a lattice according to the positioning information maintained by the current server; and generating a navigation path by using latticesnot occupied by the obstacles of a corresponding area according to a navigation start point and a navigation terminal point as well as a vehicle type. Through adoption of the navigation method, the vehicle can be guided in a field without paths but with moving obstacles.

Description

technical field [0001] The invention relates to computer application technology, in particular to a navigation method. Background technique [0002] For the current existing navigation path planning, all road paths that exist statically are used for navigation. All road paths are drawn manually in advance, and then the established path is used to generate Navigation path, the planning scheme of this navigation path can only be applied on urban roads. [0003] However, for areas where there is no path and there are dynamically changing obstacles, such as the cargo yard area, the above-mentioned traditional navigation scheme cannot be used to generate an optimal navigation path. [0004] In practical application, due to the needs of cargo loading and transportation in the cargo yard area, a large number of trucks often come in and out frequently, and the stacking of various goods in the cargo yard is not fixed and temporary in a short period of time. Dynamic changes, the fea...
