Abstract

The invention discloses an image data transmission method, device and system. The method is applied to a programmable logic device, and the programmable logic device is bridged between a graphic processing unit and a display screen of AR equipment through a display interface. The method comprises the following steps of: receiving first image data transmitted by the graphic processing unit, wherein the first image data is obtained by compressing original image data by the graphic processing unit according to a preset compression algorithm; decompressing the first image data according to a decompression algorithm corresponding to the preset compression algorithm to obtain second image data; and transmitting the second image data to the display screen, so that the display screen displays the second image data. According to the image data transmission method, device and system, the data transmission pressure of the graphic processing unit is reduced while the image display effect of the AR equipment is ensured.

Description

technical field [0001] The present invention relates to the field of AR technology, in particular to an image data transmission method, device and system. Background technique [0002] Augmented Reality (AR) technology is a technology that ingeniously integrates virtual information with the real world. The goal of virtual-real fusion display technology among the three main technical points of AR is to superimpose relevant content in the virtual world in the real world. processing, and the display technology involved requires very high image resolution and refresh rate. At present, AR systems have higher and higher display requirements, such as 2K resolution for one eye and 2*2K resolution for both eyes. Combined with AR experience requirements, the refresh rate should be 100Hz, or even higher than 120Hz. Real-time processing and transmission of such a large amount of data requires a high throughput rate of the graphics processing unit interface. In view of this situation, ...
