Embodiment Construction

[0033]The main idea of ​​the present application is to process images captured by mobile devices based on high dynamic range illumination rendering technology. In the process of image processing, each step is not a simple serial relationship, but a loose unity. That is, by using multiple images with different exposures to obtain more image detail information to make up for the defect of information loss caused by dynamic range compression in images captured by mobile devices; by extracting feature points from each image and Perform feature point matching to solve the problem of image misalignment caused by human hand shaking; maintain the details of the image to the greatest extent by calculating pixel weights; The impact of alignment. In addition, using weight calculation formulas containing various information parameters, the detailed information of the image can be kept to the greatest extent by fine-tuning these parameters.

Abstract

The invention provides an image processing method and image processing equipment. The image processing method comprises the following steps of acquiring at least three continuously shot images with different exposure degrees by using mobile equipment; processing the images on the basis of high-dynamic range illumination rendering; and fusing image processing results into a result graph. By using the imaging processing method and the image processing equipment, the problem that the information of images shot by using the mobile equipment is lost due to compression of a dynamic range can be solved, ghost images caused by shaking of hands of a photographer are eliminated, and the trueness of the images is kept to a great extent.

Description

technical field [0001] The present application relates to the field of image processing, in particular to an image processing method and device. Background technique [0002] The dynamic range of image pixels (the color range from the darkest to the brightest brightness) that can be obtained by the photosensitive element of ordinary mobile devices is only 256 discrete values ​​of 0 to 255. When shooting a view, because the gap between the darkest and the brightest in the shooting area is very large, after this gap is allocated to 256 discrete values, it will not be able to show subtler colors in the captured image Variety. Therefore, when the dynamic range of illumination changes in the shooting area is large, some areas will be overexposed or underexposed, causing pixels with different color values ​​​​in these areas to present the same color, making the color of the captured image distorted . [0003] At present, in order to solve the problem that the dynamic range of t...
