Problems solved by technology

[0002] We often use mobile phones or SLR cameras to record the scenes around us. Due to the limitation of the depth of field of such traditional cameras, only part of the image can be clearly imaged in the image obtained by a single shot, and the rest of the area will be blurred due to focus and blur

Abstract

The invention discloses a full-focusing light field image composition method and system. The method comprises the steps of obtaining an optical original image; performing digital refocusing on the original image of the light field to obtain a focus stack of the light field; performing macro-pixel variance calculation on the focus stack to obtain the matching cost of spatial points; calculating an imaging index according to the matching cost; extracting images of all points in the light field original image from the focus stack through the imaging index; and forming a full-focusing light field image according to the images of all the points. According to the method, the full-focus image is solved by using the light field image, and all clear images can be obtained under the condition that the imaging complexity is not increased.

Description

technical field [0001] The present invention relates to the field of omni-focus light field images, in particular to a method and system for forming omni-focus light field images. Background technique [0002] We often use mobile phones or SLR cameras to record the scenes around us. Due to the limitation of the depth of field of such traditional cameras, only part of the image can be clearly imaged in the image obtained by a single shot, and the rest of the area will be blurred due to Focused and blurred. Although out-of-focus blur sometimes makes the photos taken have a hazy "literary" feeling, and there are some people in the photography industry who specialize in studying the use of out-of-focus, but in most application fields, camera out-of-focus is an urgent need. solved problem. Contents of the invention [0003] The purpose of the present invention is to provide a method and system for forming an all-focus light field image. By using the light field image to obtai...
