Embodiment Construction

[0065] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0066] see figure 1 , figure 1 It is a flowchart of an image deblurring method disclosed in the embodiment of this application.

[0067] Such as figure 1 As shown, the method includes:

[0068] Step S100, performing blur region detection on the image to be processed, and determining the image of the blur region;

[0069] Specifically, in actual road monitoring images, flat road surfaces and smooth vehicle surfaces will result in fewer high-frequency components in the frequency s...

Abstract

The present application discloses an image deblurring method and device. The method includes: detecting the blurred area of ​​the image to be processed, determining the blurred area image, and judging the blur type of the blurred area image. If the blurred type of the blurred area image is off Defocus radius, use the defocus blur parameter estimation algorithm based on differential image autocorrelation to determine the defocus radius, if the blur type of the image in the blur area is motion blur, use the motion blur parameter estimation algorithm based on cepstrum analysis to determine Blur direction and blur scale, bring the estimated parameters into the classical image restoration algorithm, and obtain the restored image. This application first determines the blurred area of ​​the image, and then selects different methods according to the blur type to estimate the parameters necessary for restoration, and finally restores the image to accurately recognize the license plate.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically, to an image deblurring method and device. Background technique [0002] Generally speaking, the license plate recognition system can be divided into five parts: vehicle image acquisition, image preprocessing, license plate location, character segmentation, and character recognition. However, factors such as problems with the assembly of traffic monitoring equipment, inaccurate focus during shooting, and high-speed movement of the target vehicle may cause defocus or motion blur in some areas of the image. [0003] Due to the above-mentioned out-of-focus blur or motion blur in the acquired image, the existing license plate recognition system cannot accurately identify the license plate information in the blurred position. Contents of the invention [0004] In view of this, the present application provides an image deblurring method and device, which are ...
