Embodiment Construction

[0042] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure.

[0043] In one example, multiple operators are deploying cloud VR services to realize the development of Cloud VR. Therefore, cloud devices need to render images and send the rendered images back to user terminals for display. In the prior art, when the cloud device renders the image, it directly renders the image, and then transmits the rendered image back to the user terminal, and the user terminal displays the rendered image through a time warping method. However, in the prior art, due to the poor network, it takes a long tim...

Abstract

The invention provides an image rendering method, device and equipment, and relates to an image processing technology, and the method comprises the steps: determining a target rendering resolution of a to-be-rendered image according to an actual time delay, a preset time delay and a preset rendering resolution when the actual time delay for transmitting the to-be-rendered image is determined to be smaller than the preset time delay; wherein the actual time delay represents the transmission time required for transmitting the to-be-rendered image between the user terminal and the cloud equipment; and rendering the to-be-rendered image according to the target rendering resolution to obtain and display a target image, wherein the size of the target image is larger than that of the to-be-rendered image. According to the method, the target image with the minimum size is determined through the actual time delay of the to-be-rendered image, cloud resources are greatly saved, black edges of a display area are reduced, and the technical problem that the area of the black edges of Cloud VR is large due to the fact that a network is poor is solved.

Description

technical field [0001] The present application relates to image processing technologies, and in particular to an image rendering method, device and equipment. Background technique [0002] At present, many operators are deploying cloud virtual reality technology (Virtual Reality, VR) services to realize the development of cloud VR (Cloud VR). Therefore, cloud devices need to render images and send the rendered images back to The user terminal performs display. [0003] In the prior art, when the cloud device renders the image, it directly renders the image, and then transmits the rendered image back to the user terminal, and the user terminal displays the rendered image through a time warping method. [0004] However, in the prior art, due to the poor network, it takes a long time for the cloud device to transmit the rendered image back to the user terminal, resulting in a lag in the display time of the rendered image. When the user terminal displays the rendered image thro...
