Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] The image deblurring method based on camera motion detection provided by the example of the present invention is a deblurring process based on inertial navigation technology and multi-view geometry. The parameters estimate the approximate motion trajectory of the camera; then according to the motion trajectory, the blur kernel of the image during exposure is obtained by multi-view geometry; finally, the clear image after deblurring is obtained by the Wiener filter algorithm.

[0023] Such as figure 1 As shown, the system hardware of the present invention includes a gigabit network area arra...

Abstract

The invention provides an image deblurring method based on camera motion detection. According to the image deblurring method based on the camera motion detection, motion parameters of a camera during exposure are firstly obtained through an inertial navigation device, and a rough movement locus of the camera is estimated according to the motion parameters; then a blurring core of an image during the exposure is obtained through the multi-look geometry according to the movement locus; finally, a sharp image which is deblurred is obtained according to the Wiener filtering algorithm. According to the image deblurring method based on the camera motion detection, the moving condition of the camera during the exposure can be accurately detected, the blurring core can be generated fast and accurately according to the movement locus, and finally the relatively sharp image can be obtained though inverse filtering.

Description

technical field [0001] The present invention relates to image processing technology, in particular to an image deblurring method and device. Background technique [0002] In the field of image processing, compensating for motion blur caused by camera motion during exposure has been a hot and difficult problem. There are two types of existing solutions, one is to compensate the image after the imaging has been completed, that is, to clear the blurred image through the algorithm; the other is to compensate the motion during the imaging, that is, during the exposure process Just remove the interference caused by motion and get a clear photo immediately. [0003] The first solution has an assumption that the mathematical model of image blur: Among them, B represents a blurred image, I represents a clear image, k represents a spatially invariant blur kernel, n represents additive noise, Represents a spatial convolution operation. Under the first scheme, there are two direct...
