Vehicle License Plate Deblurring Method for Video Detection

Abstract

The invention provides a license plate deblurring method for video detection. The method comprises the following steps: S1, collecting a plurality of sets of license plate data combinations includingblurred license plate images and corresponding clear license plate images, and dividing the combinations into training data sets, verification data sets and test data sets; S2, collecting a pluralityof license plate data combinations including blurred license plate images and corresponding clear license plate images. S2, designing a generation countermeasure network model of de-motion blur, the generation network includes two convolution blocks of step size, seven inversion residual blocks of Mobilenet V2 and two transposed convolution blocks; 3, training that generated antagonism network, and put the data set obtained in the step S1 into the generated antagonism network model for training; S4, on the basis of the deblurring generation countermeasure network model trained in the step S3,the license plate image blurred by the motion is input, and the output data is the generated clear license plate image. The invention can realize the license plate clarity, so as to quickly determinethe identity of the suspect, effectively help the criminal investigator to solve the case as soon as possible, and the generation network composed of Inverted Residual Block of Mobilenet V2 can betterextract the high-dimensional features.

Description

technical field [0001] The invention relates to the technical field of intelligent video monitoring, in particular to a method for removing motion blur of a license plate for video investigation. Background technique [0002] With the rapid development of science and technology, intelligent video surveillance technology is widely used in public security criminal investigation business. It has become an important means of criminal investigation technology to record the behavior of pedestrians and vehicles through video recording, and to find and track suspected targets from the video. In the actual process of handling a case, when the staff locks the suspect or the suspected vehicle, it is necessary to trace the suspect’s action route from the crime scene and nearby areas. A very difficult job, not only time-consuming but also easy to miss the target. Especially in the tracking of suspected vehicles, many license plate information cannot be recognized due to motion blur, so ...
