Embodiment Construction

[0054] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.

[0055] The concrete flow process of the inventive method is as figure 1 As shown, after the garage emergency escape map information is collected, it is preprocessed first, and the binarized image and arrow position are output, that is, the shape analysis method is used to extract the features of the contours of all shapes in the map, and the feature vector selection can be Select Hu Moment, Pi, Circumference, Area, and Concavity. Then, cluster analysis is used to classify the extracted shape features, and the parking spaces and their positions in the map are marked, and then the lane route is obtained by flood fil...

Abstract

An intelligent reconstruction method of an indoor parking guide map is characterize in that the method comprises the following steps: S1, acquiring an emergency escape map of a garage and carrying outimage preprocessing to output a binary image and an arrow position in a road; S2, identifying a parking position based on shape feature; S3, extracting road position information; S4, carrying out superposition and reconstructing a parking guide map based on the parking position and the road position. The method of the invention fills in the research blank of reconstructing the indoor parking lotguide map by using the emergency escape map automatic identification technology, has the advantages of almost zero cost, easy obtaining of data source, etc., and has extremely high popularization andcompatibility.

Description

technical field [0001] The invention relates to artificial intelligence and image processing technology, in particular to an intelligent reconstruction method for an indoor parking guidance map. Background technique [0002] With the rapid development of the social and economic level, the number of cars in China continues to grow. Although it greatly facilitates the life and travel of urban residents, it also presents a series of traffic problems, which affect traffic efficiency and reduce the driving experience of car owners. [0003] In China, several intelligent transportation service cloud providers, mainly Didi Taxi, AutoNavi Maps and Baidu Maps, use massive data for dynamic route planning, provide accurate navigation services, and greatly improve the effective utilization of roads . However, at present, these cloud service providers mainly focus on urban roads and expressways. They have not yet provided support for the last mile of driving - parking lot navigation, an...
