DETAILED DESCRIPTION

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

[0043] In one example, many operators are deploying cloud VR services and realizing the development of Cloud VR. Therefore, the cloud device needs to render the image and transmit the rendered image back to the user terminal 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 the time warp method. However, in the prior art, due to the poor network, the cloud device takes a long time 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 through the time warp method, it is necessary to adjust the position of the rendered image in the display area according to the latest acquired image, which results in a large black border area in the display area.

[0044] The present application provides an image rendering method, device and equipment, aiming to solve the above technical problems in the prior art.

[0045] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0046] Figure 1 A flowchart of an image rendering method provided in an embodiment of the present application is applied to a cloud device; Figure 1 As shown, the method includes:

[0047] 101. When it is determined that the actual delay for transmitting the image to be rendered is less than the preset delay, determine the target rendering resolution of the image to be rendered according to the actual delay, the preset delay and the preset rendering resolution; wherein the actual delay represents the transmission time required for transmitting the image to be rendered between the user terminal and the cloud device.

[0048] Exemplarily, the execution subject of this embodiment may be a cloud device. First, it is necessary to determine the quality of the existing network. When the quality of the existing network is poor, obtain the transmission time required for transmitting the image to be rendered between the user terminal and the cloud device, that is, the actual delay for transmitting the image to be rendered. Then, the actual delay is compared with the preset delay. When it is determined that the actual delay for transmitting the image to be rendered is less than the preset delay, the target rendering resolution of the image to be rendered can be determined based on the actual delay, the preset delay and the preset rendering resolution. Among them, the preset delay is the maximum time set in advance, and the preset delay is determined comprehensively based on the acceptable cloud GPU cloud resources, image rendering time, etc.; the preset rendering resolution is the maximum acceptable rendering resolution set in advance, that is, the preset rendering resolution is the rendering resolution corresponding to the preset delay.

[0049] 102. Render the image to be rendered according to a target rendering resolution to obtain a target image; wherein a size of the target image is larger than a size of the image to be rendered.

[0050] Exemplarily, by rendering the image to be rendered according to the target rendering resolution, a target image of the target rendering resolution can be obtained. In this case, the size of the target image after rendering is larger than the size before rendering.

[0051] In an embodiment of the present application, the image to be rendered is rendered according to the target rendering resolution, and the target image is obtained and displayed. When it is determined that the actual delay in transmitting the image to be rendered is less than the preset delay, the target rendering resolution of the image to be rendered is determined according to the actual delay, the preset delay and the preset rendering resolution; wherein the actual delay represents the transmission time required for transmitting the image to be rendered between the user terminal and the cloud device. The image to be rendered is rendered according to the target rendering resolution to obtain the target image. In this scheme, the actual delay of transmitting the image to be rendered over the existing network can be obtained first, and then it can be determined whether the actual delay is less than the preset delay. When it is determined that the actual delay in transmitting the image to be rendered is less than the preset delay, the target rendering resolution of the image to be rendered is calculated and determined according to the actual delay, the preset delay and the preset rendering resolution. Finally, the image to be rendered is rendered according to the target rendering resolution to obtain the target image. At this time, the size of the target image is larger than the size of the image to be rendered. Therefore, the cloud device can transmit the target image to the user terminal, and the user terminal displays the target image through the time warping method. In the process of displaying the target image, when the position of the target image in the display area is greatly changed by the time warping method, since the size of the target image has increased, a larger area of ​​the target image can be retained in the display area, thereby reducing the black border area in the display area. Therefore, the minimum size of the target image is determined by the actual delay of the image to be rendered, which greatly saves cloud resources and reduces the black border of the display area, solving the technical problem of large black border area of ​​Cloud VR caused by poor network.

[0052] Figure 2 A flowchart of another image rendering method provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the method includes:

[0053] 201. When it is determined that the actual delay of transmitting the image to be rendered is less than the preset delay, obtain the original rendering resolution of the image to be rendered.

[0054] Exemplarily, the electronic device obtains the actual delay of transmitting the image to be rendered over the existing network, and when it is determined that the actual delay of transmitting the image to be rendered is less than a preset delay, obtains the original rendering resolution of the image to be rendered.

[0055] 202. Determine a target rendering resolution of the image to be rendered according to the actual delay, the preset delay, the preset rendering resolution, and the original rendering resolution.

[0056] In an example, the target rendering resolution is:

[0057]

[0058] Among them, T max is the preset delay, t is the actual delay, Wmax is the default rendering resolution, W original is the native rendering resolution.

[0059] Exemplarily, the electronic device may calculate and determine the target rendering resolution of the image to be rendered based on the preset formula (1) according to the actual delay, the preset delay, the preset rendering resolution, and the original rendering resolution. The preset formula (1) is as follows:

[0060]

[0061] Among them, T max is the preset delay, t is the actual delay, W max is the default rendering resolution, W original is the original rendering resolution, k is the preset adjustment coefficient, so according to the preset formula (1), the preset formula (2) can be obtained, and the target rendering resolution w can be determined according to the preset formula (2). The preset formula (2) is as follows:

[0062]

[0063] Therefore, according to the above formula, when the quality of the existing network is extremely good, that is, when the network delay approaches 0, the target rendering resolution w approaches W original ; When the actual delay of the existing network approaches the preset delay T max When the target rendering resolution w approaches W max ; When 0<t<T max When , the target rendering resolution w has a certain linear relationship with the network delay t.

[0064] 203. Render the image to be rendered according to the target rendering resolution to obtain a target image.

[0065] For example, this step can be referred to Figure 1 Step 102 in the above is not described in detail.

[0066] 204. When it is determined that the actual delay for transmitting the image to be rendered is greater than or equal to the preset delay, the preset delay is determined as the actual delay, and the step of determining the target rendering resolution of the image to be rendered according to the actual delay, the preset delay and the preset rendering resolution is repeatedly executed.

[0067] Exemplarily, when it is determined that the actual delay of transmitting the image to be rendered is greater than or equal to the preset delay, in order to avoid excessive waste of cloud resources, the preset delay is directly determined as the actual delay. At this time, the value of the actual delay is equal to the value of the preset delay. Then, the actual delay, preset delay and other values ​​are substituted into the preset formula (2), and the above step 202 is repeated.

[0068] 205. If it is determined that the rendering fails, a prompt message is generated and displayed.

[0069] For example, if it is determined that the rendering fails, an image containing the target rendering resolution cannot be generated, and a prompt message can be directly displayed on the cloud device to remind the user of the rendering failure. Alternatively, the generated prompt message can be sent to the user terminal to remind the user of the rendering failure.

[0070] In an embodiment of the present application, when it is determined that the actual delay of transmitting the image to be rendered is less than the preset delay, the original rendering resolution of the image to be rendered is obtained. According to the actual delay, the preset delay, the preset rendering resolution and the original rendering resolution, the target rendering resolution of the image to be rendered is determined. The image to be rendered is rendered according to the target rendering resolution to obtain the target image. When it is determined that the actual delay of transmitting the image to be rendered is greater than or equal to the preset delay, the preset delay is determined as the actual delay, and the step of determining the target rendering resolution of the image to be rendered according to the actual delay, the preset delay and the preset rendering resolution is repeated. If it is determined that the rendering fails, a prompt message is generated and displayed. Therefore, the cloud device can transmit the target image to the user terminal, and the user terminal displays the target image through the time warping method. In the process of displaying the target image, when the position of the target image in the display area is greatly changed by the time warping method, since the size of the target image has increased, a larger area of ​​the target image can be retained in the display area, thereby reducing the black border area in the display area. Therefore, the minimum size of the target image is determined by the actual delay of the image to be rendered, which greatly saves cloud resources and reduces the black border of the display area, and solves the technical problem of large black border area of ​​Cloud VR caused by poor network.
