Embodiment Construction

[0028] In the following, the present invention will be further described by using the following embodiments in conjunction with the accompanying drawings.

[0029] License plate blocking detection system of the present invention such as figure 1 shown, which includes,

[0030] The vehicle capture positioning module 1 is used to capture the vehicle image at the monitoring position and locate the vehicle profile in the captured vehicle image; the vehicle capture positioning module 1 includes: a vehicle capture unit 11 and a vehicle positioning unit 12 .

[0031] The vehicle capture unit 11 is used for capturing images of vehicles passing on the road at the monitoring point. The function of this unit is to obtain a clear and complete vehicle image for subsequent occlusion detection and analysis. There are many mechanisms for capturing images of vehicles. The common methods include ground sensing coil triggering capture, video analysis triggering capture, and radar triggering ca...

Abstract

The invention discloses a license plate sheltering detection system, which belongs to the field of intelligent transportation control and comprises a vehicle snap-shot location module (1), a processing module (3) and a license plate sheltering judgment module (2), wherein the vehicle snap-shot location module (1) is used for shooting vehicle images at detection positions and locating vehicle outlines in the snap-shot vehicle images, the processing module (3) is used for processing situations of spiteful sheltering of license plates, and the license plate sheltering judgment module (2) comprises a license plate location module (21), a license plate character analysis module (22) and a sheltering analysis module (23). The license plate location module (21) is used for locating license plate area in the snap-shot vehicle images, the license plate character analysis module (22) is used for determining appeared character positions and positions where deficiency characters may exist according to the appeared character positions in the license plate area, and the sheltering analysis module (23) judges whether spiteful sheltering exists or not according to textures of deficiency characters positions and enables judgment results to be sent to the processing module. The license plate sheltering detection system solves the technical problem that the existing detection system can not distinguish spiteful sheltering situations.

Description

technical field [0001] The invention belongs to the field of intelligent traffic control systems, and in particular relates to a license plate blocking detection system and detection method. Background technique [0002] License plate recognition technology is one of the most widely used pattern recognition technologies in the field of intelligent transportation. At present, most off-site violation detection systems in the intelligent transportation industry (such as electronic police monitoring systems for running red lights, speeding capture systems, etc.) are based on license plate recognition technology. The realization of automatic detection, automatic capture, automatic identification and automatic storage is one of the technical foundations of intelligent traffic management. [0003] The technical basis of license plate recognition technology is image processing technology and character recognition technology. License plate recognition technology is usually divided in...
