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 target observation and blur restoration method. The method uses multiple cameras of the same model with continuous shooting functions to capture and shoot moving targets in the same field of view to obtain observation images; the obtained observation images are separately processed. Motion blur function estimation and segmentation extraction are used to obtain respective motion blur target images; using the obtained motion blur target image and motion blur function, a spatial domain joint restoration algorithm is used to obtain a clear target image. The present invention has low requirements for hardware equipment and only requires a plurality of popular digital cameras with continuous shooting functions to solve the problems of high-speed moving target observation and blur 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 Exposure Photography:Motion Deblurring Using Fluttered Shutter[C] / / Proceedings of ACM SIGGRAPH 2006.Boston, Massachusetts: ACM, 2006:795- 804.), coded exposure (Coded Exposure, CE) that quickly opens and closes the shutter within the exposure time of the camera can obtain a reversible motion blur function, that is, the motion blur function has no zero point in the frequency domain, th...
