Image processing method, image processing device and computer equipment

Abstract

The embodiment of the invention discloses an image processing method, an image processing device and computer equipment. The image processing method disclosed by the embodiment of the invention comprises the following steps that: a graphics processor receives information, sent by a central processing unit, of a scene in a preset range around a target object to be rendered; the graphics processor renders the received scene to obtain a scene depth parameter, and the scene is obtained through being shot by a camera positioned in a position of a ray light source; the graphics processor renders a target object to be rendered to obtain a rendering depth parameter, and the target object to be rendered is obtained through being shot by a camera not positioned at in a position of the ray light source; the graphics processor calculates the environment light shielding picture of the target object to be rendered in each ray light source direction according to the scene depth parameter and the rendering depth parameter; and the graphics processor carries out stacking on the environment light shielding pictures in each ray light source direction to obtain an output image. The image processing method, the image processing device and the computer equipment provided by the embodiment of the invention have the advantage that the image processing efficiency can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to an image processing method, device, and computer equipment. Background technique [0002] With the vigorous development of online games today, people have higher and higher requirements for the realism of game scenes. Ambient Occlusion (AO) is an important part of Global Illumination (GI) technology. AO describes the occlusion value of each point on the object surface and other objects in the scene. AO is usually used to attenuate the light in the The light value on the surface of the object, and then generate shadows to enhance the layering of the space, the realism of the scene, and the artistry of the picture. [0003] However, in the process of game development, the inventors of the present invention found that the mainstream AO texture baking software on the market is mostly based on the central processing unit (Central Processing Unit, C...

Problems solved by technology

[0003] However, in the process of game development, the inventors of the present invention found that the mainstream AO texture baking software on the market is mostly based on the central processing unit (Central Processing Unit, CPU), and the processing efficiency of the central processing unit for image data is relatively low. Low, so the baking efficiency of AO texture is also very low, usually it takes several hours to bake an AO texture; there are also some baking software that can put part of the processing on the CPU and the other part of the processing on the graphics processor (Graphic Processing Unit, GPU), but the algorithms involved in this kind of baking software are often very complicated, and eventually the problem of low image processing efficiency will occur
