Abstract
The invention provides a new energy vehicle abnormal parking big data detection method oriented to a smart city. Under the condition that a new energy automobile image database is constructed, representative new energy automobile template images are selected. And photographing the target area by using an existing camera to obtain a to-be-detected image. And performing similarity calculation on the to-be-detected image and the template image, and judging whether the to-be-detected image contains the new energy automobile or not according to a similarity calculation result. In addition, a license plate area is detected and processed by using a target detection technology and a super-resolution reconstruction technology, and on the basis, license plate information is accurately identified by using a plurality of OCR technologies in a cross mutual inspection mode. And after a preset time interval, the camera photographs the same target area, and after a series of processing, whether the original new energy vehicle is still parked in the same area is judged, so that the abnormal parking condition of the new energy vehicle is accurately and comprehensively detected.
