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.
