Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] The present invention provides a vehicle license plate detection device, which is described below by taking software implementation as an example, but the present invention does not exclude other implementations such as hardware or logic devices. Such as figure 1 As shown, the hardware environment in which the device operates includes CPU, memory, non-volatile memory and other hardware. As a virtual device on a logical level, the vehicle license plate detection device operates through a CPU. The device includes a bayonet statistics unit, a connected segment division unit and a flipped license plate determination unit. Please refer to figure 2 , the use and operation process of the device includes the following steps:

[0026] Step 101, the bayonet statistics unit counts the bayonets that the vehicles to be inspected pass through sequentially within the fi...

Abstract

The present invention provides a method and device for detecting a vehicle flip on an open road. The method includes: counting the bayonets that the vehicles to be inspected pass through sequentially within a preset time period; judging whether the bayonets are not connected according to the bayonet connection information , if it is, divide it into at least two connected segments; according to the information in the passing record of the vehicle to be inspected, the vehicle violation situation and the bayonet connection information, use trajectory collision and difference operation to obtain the suspected flop between adjacent connected segments license plate. The method of the present invention can effectively improve the supervision and monitoring of vehicles using the automatic card reversing device, and can form an effective deployment and control strategy accordingly, and significantly improve the case-solving efficiency of public security criminal investigators and traffic police.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a method and device for detecting a vehicle flip card. Background technique [0002] The automatic flipping of motor vehicle license plates refers to the automatic flipping of vehicles with two sets of license plates by using an automatic flipping device. Usually just tap the remote control in your hand, and the current license plate will be automatically flipped to another license plate. Generally, the flipping of a pair of license plates can be completed within 10 seconds. The automatic flopping of the motor vehicle number plate is a kind of illegal decking. Automatic flopping can not only avoid electronic eyes, but also impose illegal records on other car owners anytime and anywhere. The harm of automatic flop is self-evident. For example, an illegal act of evading off-site law enforcement directly leads to traffic chaos; drivers no longer worry about being punis...
