Abstract:

In order to achieve the rapid automatic detection and query of the empty parking spaces, a correction and stitching method of parking image distortion is proposed. Images with some overlapped regions captured by adjacent cameras are stitched into a large field image mosaic that comprehensively describes the parking information, so that the empty parking spaces are detected. And pictures show vertical distortion and horizontal distortion due to the camera perspective and perspective effects. For the sake of intuitively displaying the occupation and empty information of all parking spaces and facilitating the vehicle management, all parking images are corrected to be with the same perspective before image mosaic. Experimental results show that the algorithm is convenient for users to directly observe empty parking spaces, and it is conducive to process images further for automatic detection of the parking spaces.

Key words: parking spaces detection;graphic distortion;graphic correction;image stitching
