Abstract

The embodiment of the invention discloses an image rendering method. The method comprises the following steps of: rendering a scene graph and a depth graph of a current scene, wherein the depth graph comprises depth information (of the current scene) corresponding to each pixel point in the scene graph; calculating the weight of the depth information of each pixel point in a preset area in the scene graph, wherein the total sum of the weights of the depth information of all the pixel points is taken as a gathering distance; respectively calculating the diameters of confusion circles of the pixel points in the scene graph by virtue of the depth graph and the gathering distance; and respectively carrying out bilateral depth filtering on each pixel point in the scene graph based on the diameter of the confusion circle of each pixel point in the scene graph. Correspondingly, the embodiment of the invention further provides image rendering equipment. The image rendering method and equipment provided by the embodiment of the invention can improve the efficiency of image rendering.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image rendering method and device. Background technique [0002] The essence of image rendering is the real-time calculation and real-time output of graphics data. Currently, the widely used image rendering technology is online cumulative rendering technology. This technology can simulate the effect of depth of field. This technology is implemented in the way of cumulative buffering. The so-called cumulative buffering is to accumulate a series of drawing results. After all the images are rendered, the drawing results of the cumulative buffering are connected into a complete image, and The image is fed into the frame buffer and finally displayed on the screen. The pixel values ​​of the final image generated in this technique are accumulated from the pixel values ​​of the same pixel points in multiple images. In this way, it is necessary to adopt the technology of drawi...
