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 invention provides a method and a device for detecting turnover of a number plate on an open road. The method comprises the following steps: calculating checkpoints by which vehicles to be detected sequentially pass in a preset time period; determining whether the checkpoint is communicated or not according to communication information of the checkpoint, and dividing the checkpoint into at least two communication sections if the checkpoint is communicated; acquiring a suspect overturned number plate between adjacent communication sections by adopting track collision and subtraction operation according to information in passing records of vehicles to be detected, vehicle violation condition and checkpoint communication information. According to the method, supervision and monitor on fake plate vehicles using an automatic plate overturning device can be effectively improved, an effective deploy-control strategy can be formed, and the detection efficiency of public security criminal investigators and traffic police can be remarkably improved.

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...
