Abstract

The invention discloses a virtual reality image processing apparatus and method. The method comprises the following steps of A, determining a sight point position and a sight line direction; B, according to the sight point position, the sight line direction and a view frustum culling algorithm, determining a scene model in a corresponding view frustum region in a preset global scene model; C, searching for a visible scene model in the scene model in the view frustum region by adopting an occlusion culling algorithm to serve as a target scene model; and D, performing fine granularity renderingprocessing on a virtual display image displayed in the target scene model. According to the apparatus and the method, the visible scene model is searched for in the scene model in the view frustum region by adopting the occlusion culling algorithm to serve as the target scene model; the scene model outside a view frustum and the invisible scene model in the view frustum can be culled; and the visible scene model in the view frustum region is rendered to generate a virtual scene image, so that the processing efficiency of an image processor is improved.

Description

technical field [0001] The invention relates to the technical field of virtual reality image processing, in particular to a virtual reality image processing device and method. Background technique [0002] Virtual reality technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. It can immerse users into the environment. Virtual reality technology is a collection of simulation technology and computer graphics, human-machine interface technology, multimedia technology, sensor technology, network technology and other technologies. It mainly includes simulated environment, perception, natural skills and sensing equipment, etc., but the existing technology has low processing efficiency of the image processor, high performance requirements for the display chip, and cannot perform three-dimensional display on two-dimensional layers such as shutdown control, volume control, and power display. ...
