New energy vehicle abnormal parking big data detection method for smart city

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.

Description

technical field [0001] The invention relates to the field of detection of new energy vehicles, in particular to a large data detection method for abnormal parking of new energy vehicles facing smart cities. Background technique [0002] In modern society, the construction of smart cities is playing an increasingly important role, providing great convenience to the people. However, due to the need for charging and short cruising range, new energy vehicles often park abnormally for a long time in the same place, which significantly hinders the smooth construction of smart cities. [0003] Traditional object detection and other related methods can often detect the abnormal parking of some new energy vehicles, but they cannot accurately and comprehensively detect the abnormal parking of new energy vehicles, which brings many practical difficulties to the construction of smart cities. Therefore, how to propose a large data detection method for abnormal parking of new energy vehi...
