Image processing method, device, electronic device and storage medium

Abstract

The disclosure relates to an image processing method, device, electronic equipment, and storage medium. The image processing method includes acquiring a colored image of a light-receiving object in the current scene, and obtaining the position of the light-receiving object according to the current position of the light-receiving object in the image coordinate system of the current scene. According to the target position in the camera coordinate system, the illumination color map of the camera device is obtained, and the colored image is processed according to the target position and the illumination color map of the camera device to obtain the illumination image of the light-receiving object. The disclosure realizes the processing of the colored image according to the illumination color map without processing the colored image pixel by pixel, shortens the rendering time and improves the real-time performance of illumination calculation, and the illumination color map is generated according to the properties of the light source in the current scene, and the illumination color map It can change with the properties of the light source in the current scene, and the lighting conditions represented by the lighting color map can be consistent with the lighting conditions of the light sources in the current scene, so as to improve the rendering realism.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to an image processing method, device, electronic equipment, and storage medium. Background technique [0002] In related technologies, with the increasing popularity of applications with rendering requirements such as games, virtual reality (Virtual Reality, VR) and augmented reality (Augmented Reality, AR), the requirements for rendering realism are getting higher and higher. In order to enhance the rendering realism, Add lighting processing for light sources in the rendering process. The impact of light sources on rendering realism is reflected in the following two aspects: [0003] One is the change of attributes such as the position of the light source and the direction of illumination, which will affect the illumination image of the light source to the object irradiated by the light source (referred to as the light-receiving object). The second is that w...

Second, when the light-receiving object enters the range of the light source, it will also be affected by the light, which will affect the rendering realism, especially the rendering realism of the light-receiving object

[0005] The other is to perform lighting calculations based on the fragment shader in the camera device. The process is: obtain the colored image of the light-receiving object in the current scene, and the colored image is obtained by coloring the light-receiving object to reflect the coloring effect of the light-receiving object , according to the position of the light source and the light direction and other attributes, the lighting operation is performed pixel by pixel on the colored image of the light-receiving object. The lighting operation pixel by pixel will consume a lot of computing time, resulting in the rendering time will increase with the number of light sources, and the rendering time will increase. Increase will reduce the real-time performance of lighting calculation
