Abstract

The invention is suitable for the field of multi-media application and provides a method and a device for confirming depth of field in a virtual scene. The method comprises the following steps: obtaining parameter information of the virtual scene, a lateral resolution of display equipment and a viewing distance, and then calculating the depth of field of an object in the virtual scene according to the parameter information of the virtual scene, the lateral resolution of the display equipment and the viewing distance. When the virtual scene is constructed or after the virtual scene is constructed, the information required by the depth of field calculation is obtained, and the depth of field in the virtual scene is correspondingly calculated, so that a design developer can obtain the depth of field in the virtual scene during a constructing process of the virtual scene. Meanwhile, the effect of the depth of field is modified before the object in the virtual scene is displayed on the display equipment, so that the debugging period of a 3D display effect is shortened and the developing efficiency of the virtual scene is increased.

Description

technical field [0001] The invention belongs to the field of multimedia applications, in particular to a method and device for determining the depth of field of a virtual scene. Background technique [0002] With the advancement of technology, 3D display has become the mainstream image display technology, and 3D movies and 3D pictures have become popular in the market. At present, the traditional method of determining the depth of field of a virtual scene is commonly used in 3D display, that is, after the construction of the virtual scene is completed, the depth of field in the virtual scene is determined by measuring the parallax of the display elements on the display device. This method is not conducive to modification of the depth of field effect by design and development personnel because the specific depth of field effect can only be seen on the final display screen. Contents of the invention [0003] The purpose of the embodiments of the present invention is to prov...
