Abstract

The invention relates to the technical field of image processing, and especially relates to an image light supplementing method and device and a computer device. The image light supplementing method comprises the steps of obtaining a compensation illumination parameter of a three-dimensional model corresponding to an original image; performing secondary illumination on the three-dimensional modelaccording to the compensation illumination parameter data, and collecting a light supplementing image of the three-dimensional model after the secondary illumination; and carrying out image fusion onthe light supplementing image and the original image to obtain a target image. According to the scheme provided by the invention, the compensation illumination parameter of the three-dimensional modelcorresponding to the original image is acquired, and the to-be-compensated area in the original image is subjected to three-dimensional light compensation according to the compensation illumination parameter, so that the image brightness is effectively improved, and the real-time requirement of image light compensation can be met.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, the present application relates to an image supplementary light method, device and computer equipment. Background technique [0002] In the actual shooting process, especially when a single light source is used, since the light emitted by the light source cannot be completely evenly irradiated on all angles of the object being photographed, in order to make up for the shadow defects caused by uneven lighting, reflectors are often used in actual operations However, in some cases, it is not possible to fill in the light of the object in real time, or even if the light is supplemented, the image details may be lost due to overexposure during the shooting process. [0003] In order to solve this situation, the existing technology often adopts the method of re-lighting the captured photos in the later stage, that is, the image re-lighting technology, using the rea...
