Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] In order to obtain clear images of high-speed moving targets, image restoration methods based on computational photography are different from ordinary image capture from the image acquisition stage. Firstly, a special image acquisition device is used for shooting, and then multiple images obtained by shooting are jointly restored.

Abstract

The invention discloses a moving object observation and fuzzy restoration method which comprises the following steps: a plurality of cameras of the same model that have a continuous shooting function are used for capturing photographs of moving objects in the same view field in a fixed manner, observation images are obtained; the obtained observation images are respectively subjected to moving fuzzy function estimation and segmentation extraction operation, and corresponding moving fuzzy object images are obtained; the obtained moving fuzzy object images and moving fuzzy functions are used, and clear object images can be obtained via a space domain combination restoration algorithm. The moving object observation and fuzzy restoration method has low requirements for hardware equipment, and only a plurality of digital cameras, popular in markets, that have a continuous capture function are required for solving a problem of high speed moving object observation and fuzzy restoration.

Description

technical field [0001] The invention relates to an image restoration processing method, in particular to a digital image motion blur restoration processing method. Background technique [0002] Observation and identification of high-speed military targets, as well as the identification of responsibilities by the traffic department through the scene video of traffic accidents, etc., involve the observation and fuzzy restoration of high-speed moving targets. [0003] Methods in the prior art include two kinds: [0004] One is proposed by Raskar et al. (Raskar R, Agrawal A, Tumblin J, et al.Coded ExposurePhotography:Motion Deblurring Using Fluttered Shutter[C] / / Proceedings of ACM SIGGRAPH2006.Boston, Massachusetts: ACM, 2006:795-804 .), the coded exposure (Coded Exposure, CE) of quickly opening and closing the shutter within the camera exposure time can obtain a reversible motion blur function, that is, the motion blur function has no zero point in the frequency domain, so tha...
