Abstract

The invention relates to a method for processing a virtual reality image. The method comprises the following steps: (a) acquiring left eye image data and corresponding right eye image data; (b) obtaining a difference pixel matrix of the left eye image and the right eye image; (c) obtaining a to-be-processed macro block of the difference pixel matrix; (d) acquiring a sampling point and a non-sampling point of the to-be-processed macro block; (e) obtaining a predicted residual error of the sampling point and the non-sampling point; (f) obtaining the distribution type of the prediction residual error of the to-be-processed macro block; and (g) obtaining the quantized residual error of the macro block to be processed according to the distribution type. Through the difference information acquisition of the left eye video data and the right eye video data and the compression encoding method with the high compression ratio, the compression loss of complex texture images is reduced, the numberof transmission bits is further reduced, and the bandwidth compression rate is increased.

Description

Technical field [0001] The invention belongs to the technical field of virtual reality data processing, and specifically relates to a method and equipment for processing virtual reality images. Background technique [0002] With the advancement of science, virtual reality equipment (Virtual Reality, referred to as VR) technology has become a hot research technology today. The display principle is that the left and right eye screens display the images of the left and right eyes respectively. After the human eyes obtain this information with differences, There is a three-dimensional feeling in the mind. [0003] In order to achieve a high-quality VR application experience and meet the three performance requirements of VR applications: 1) low response delay, 2) high frame refresh rate and 3) high-quality images, VR systems usually hand over the heavy rendering work to a powerful The host is complete. The host transmits the rendered frame to the head-mounted display worn by the user ...
