Embodiment Construction

[0013] As shown in FIG. 1 and FIG. 2 , the fast calculation method A of the path calculation device of the present invention includes a map vector B, a grid path C, a partial path unit D, a path indexing E and a path calculation F. The map displayed by the device A1 is displayed as a grid to form a map vector B, and each path of all places is displayed in each grid, and each path displayed by each grid reaches the grid paths C of all other grids, In the grid display, the common paths of all routes are searched to form part of the path unit D, and the path index E is made between each grid path C and the part of the path unit D, so as to achieve the path calculation F, through each network The continuous path connected between the grid paths and the grid path formed near the search start and end points are matched with the connection of the actual start point and the end point, and a three-stage complete optimal path is completed by the fixed mode of part of the path unit, so th...

Abstract

The invention relates to a rapid computation method for a path computer device, belonging to electromechanical field. It comprises a map vector for grid displaying the map; a grid path connected with the map vector and used for displaying paths of all places in each grid of the map vector; a partial path unit connected with the grid path and used for displaying common paths of paths in the grid; a path indexing unit connected with the partial path unit and used for indexing paths of each pair of grids; and a path calculator connected with the path indexing unit and used for connecting the actual start / end point to the searching paths through the searching paths among grids and searching grid paths in the vicinity of start / end point when searching paths to form a complete and optimal path. The invention has the advantages of grid display, low information quantity requirement for calculation, saving time for calculating paths, convenient usage, and high practicability.

Description

technical field [0001] The present invention relates to electromechanical, in particular to a fast calculation method of a path calculation device. Background technique [0002] As we all know, the high development of today's technology has deeply affected people's changes in various things in daily life, and it is developing towards a more accurate, more efficient and more humanized trend; the technology of satellite navigation systems has become increasingly mature, and users can Automatically perform position input for the starting point of the location and the end point of the location to be reached, so as to calculate a complete path through the satellite navigation system, and perform a positioning and navigation function through the display screen. The satellite navigation system is at the location input by the user. After you reach the desired location, you need to do a road section analysis to calculate a route navigation. The time it takes to calculate the route of...
