Abstract

The invention provides a map image processing method, device and equipment and a readable storage medium, and the method comprises the steps: repeatedly executing a preset graph with the maximum area, which can be accommodated by a communication region of a map image of a determined region, a step of covering a preset graph with an receivable maximum area in a connected region of the map image of the region until a connected region larger than a preset area threshold does not exist in the map image of the region; and taking the position range corresponding to all the preset graphs as the position range of the region. According to the method, the map image of the area is processed, the position range of the simple graph with the point located inside or outside the area is used for replacing the position range of the covered map area, the positioning of the target object in the map area is simplified, and the positioning robustness is improved while the positioning time is saved.

Description

technical field [0001] The present invention relates to the field of big data analysis technology of intelligent network connection of transportation, in particular to a map image processing method, device, equipment and readable storage medium. Background technique [0002] In commercial vehicle transportation, it is necessary to locate the administrative area where the target vehicle is located according to vehicle monitoring, so as to conduct intelligent network connection and big data analysis of the target vehicle. Specifically, in the prior art, it is generally determined whether a certain coordinate is within the boundary line according to the boundary line of the administrative area to determine the location of the administrative area where the vehicle is located. However, since the boundary line of general administrative regions is a simple closed irregular curve, its irregularity makes it difficult to judge a point in the boundary line in calculation, and the calcu...
