The image rendering effect testing method of the embodiment of the invention can be realized by the terminal, and can also be realized by the terminal and the server together.

The method is described below by taking an example that the terminal and the server realize the image rendering effect test method together.

As shown in fig. 1, the image rendering effect testing system provided by the embodiment of the present invention includes a terminal 10, a server 20, and the like; the terminal 10 and the server 20 are connected via a network, for example, a wired or wireless network connection, wherein the terminal 10 may exist as a terminal for sending an image rendering effect test request to the server 20.

Among them, the terminal 10 may be a terminal that generates an image rendering effect test request for transmitting the image rendering effect test request to the server 20.

The server 20 may be configured to store the rendering code file, and after receiving the image rendering effect test request sent by the terminal 10, may send the rendering code file corresponding to the image rendering effect test request to the terminal 10 according to the image rendering effect test request.

The terminal 10 may be configured to render an image to be rendered based on a rendering code file for which a rendering effect test is required, obtain a test rendering image, obtain a reference rendering image, compare the test rendering image with the reference rendering image to obtain an image comparison result, and determine a test result of the rendering code file according to the image comparison result.

The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

The embodiment of the present invention will be described from the perspective of an image rendering effect test apparatus, which may be specifically integrated in a terminal.

As shown in fig. 2, a specific flow of the image rendering effect testing method of the present embodiment may be as follows:

201. and rendering the image to be rendered based on the rendering code file needing to be subjected to the rendering effect test to obtain a test rendering image.

In some examples of the embodiment of the present invention, the rendering code file may be a code file written by a technician for an image rendering effect test requirement, and it may be understood that the rendering code file may include not only a program code that can be executed, but also rendering information that is required during an image rendering effect test, and the like.

It can be understood that a skilled person may generate rendering code files corresponding to different image effects in advance according to the different image effects.

The rendering information may be information required in the image rendering effect test process, such as which range, which position, what time point and/or what color is displayed in the display area of the terminal, and the like.

And the image to be rendered is an image which is not rendered by the rendering code file. It is understood that the image to be rendered may be rendered by another rendering code file before testing, which is not limited in the embodiment of the present invention.

It can be understood that, the rendering code file may also render the video, at this time, the image to be rendered is a video frame in the video to be rendered, the video to be rendered includes at least two video frames, and the step "rendering the image to be rendered based on the rendering code file requiring the rendering effect test to obtain the test rendering image" includes:

rendering each video frame of a video to be rendered based on a rendering code file needing to be subjected to a rendering effect test to obtain a test rendering video;

Specifically, when determining the test rendering image, any video frame may be determined as the test rendering image, or a video frame whose rendering is completed may be determined as the test rendering image from the test rendering video.

The rendering architecture of the video may be as shown in fig. 3: the method mainly comprises a UI interaction layer, a rendering engine layer and a three-party SDK layer. Among them, the UI interaction layer has a main role to take charge of interaction with the user and record the user's operation in the draft of the rendering engine layer. The rendering engine layer mainly comprises a rendering engine and a draft: the rendering engine is responsible for construction of the rendering chain, rendering of the rendering chain and the like, and the draft is mainly data record of operation of the UI interaction layer and is responsible for data interaction between the UI and the rendering engine. The three-party SDK layer is mainly some rendering related algorithms, and is accessed into a rendering chain through a rendering engine to realize a rendering effect.

The common constructed rendering chain mainly comprises rendering links such as texture input, background replacement, facial beautification, filter and the like.

202. And acquiring a reference rendering image, wherein the reference rendering image is an image obtained by adding the target rendering effect of the rendering code file to the image to be rendered.

The target rendering effect may be a rendering effect that a user or a technician specifies that an image and/or video displayed on the terminal has, for example, a special effect that the image a is set at an edge of the image and a lighting effect is added to the edge of the image, the target rendering effect is that the edge of the image has a lighting effect, and so on.

Specifically, an application program before version iteration may be adopted to render an image to be rendered or a video to be rendered, so as to obtain a reference rendered image or a reference rendered video.

It can be understood that the rendering code file may also render a video, where a reference rendering image is a reference video frame in a reference rendering video, the reference rendering video includes at least two reference video frames, and the reference rendering video is a video obtained by adding a target rendering effect of the rendering code file to the video to be rendered.

Correspondingly, the step "acquiring a reference rendering image" may specifically include:

acquiring a reference rendering video;

The target frame position may be obtained for the frame number in the test rendering video according to the test rendering image, or the target frame position may be determined according to a time point of the test rendering image in the test rendering video.

Taking the comparison of the beauty rendering effects as an example, when the rendering chain renders to a beauty node, the video frame (Ft) at the current time point t in the test rendering video can be read out as a reference rendering image according to the corresponding time t of the test rendering image obtained by the current rendering. And after the beauty node is rendered, comparing the rendered beauty frame (test rendering image) with the reference rendering image.

In the actual application process, a technician can simulate, manually or by scripts, in a stable version of the processing application, a user to add various effects to the video, and then generate a candidate rendered video processed by one or more rendering nodes. The candidate rendered videos may be packaged and placed into the server. After a developer submits a code, the server is activated, the server compiles an APP according to the current code, reads in a video to be rendered and a candidate rendering video which are prepared in advance, runs the APP, and compares an effect file (test rendering video) generated by each rendering effect with an effect video file (reference rendering video) corresponding to the pre-generated rendering effect in the server.

That is, the reference rendered video may be a part of candidate rendered videos including the videos corresponding to at least two different rendering effects;

the obtaining of the reference rendered video comprises:

according to the target rendering effect of the rendering code file, determining the video corresponding to the target rendering effect from the candidate rendering videos;

The candidate rendered video may be a video file, in this case, the reference rendered video may be a segment of video in the candidate rendered video, and the video position is a position of the reference rendered video in the candidate rendered video. Alternatively, the candidate rendered video may be a set of a plurality of video files, in this case, the reference rendered video may be one of the candidate rendered videos, and the video position may be a storage position of the reference rendered video.

203. And comparing the test rendering image with the reference rendering image to obtain an image comparison result.

The comparison mode can be that the test rendering image and the reference rendering image are compared one by one, the proportion of the matched pixel points to the total pixel points is calculated, and the image comparison result is obtained according to the proportion.

Or, the step of comparing the test rendering image with the reference rendering image to obtain an image comparison result may specifically include:

calculating difference values of each test pixel point in the test rendering image and corresponding pixel points in the reference rendering image respectively to obtain a pixel difference value corresponding to each test pixel point;

constructing a difference image based on each pixel difference value;

In some alternative examples, the width and height of the difference image may be reduced by 10 times to improve the computational efficiency. And then calculating the pixel mean square error of the reduced difference image.

The step of obtaining an image comparison result according to the pixel mean square error may specifically include:

if the pixel mean square error is not larger than a preset contrast threshold value, obtaining an image contrast result of passing the image contrast;

That is, the mean square error can be compared to a given threshold, and if the mean square error is less than the given threshold, it indicates that the current image is consistent, otherwise the image is not the same.

After the step of comparing the test rendering image with the reference rendering image to obtain an image comparison result, the method for testing the image rendering effect provided by the embodiment of the present invention may further include:

if the image comparison result is that the image comparison is passed, determining a video frame from each video frame which is not compared in the test rendering video as a new test rendering image;

In the embodiment of the present invention, for example, as shown in fig. 4, a comparison of a single-node rendering result may be performed for each rendering effect, for example, when a background node is compared, a background node rendering result is obtained after a material is rendered by the background node, then the result is compared with a video frame of a video stored in the background node at a corresponding time point, and if two video frames are consistent, a next-node rendering comparison is performed until the result is completed. If any of the comparison results are inconsistent, the test may be terminated.

204. And determining a test result of the rendering code file according to the image comparison result.

If any comparison result is inconsistent, the operation is stopped, and the server can inform the person submitting the codes of the nodes with problems and prevent the codes from being merged. If the comparison results of all the nodes are consistent, the currently submitted code is incorporated into the code backbone.

As can be seen from the above, in the embodiment of the present invention, based on a rendering code file for which a rendering effect test is required, rendering an image to be rendered to obtain a test rendering image, and obtaining a reference rendering image, where the reference rendering image is an image obtained by adding a target rendering effect of the rendering code file to the image to be rendered, comparing the test rendering image with the reference rendering image to obtain an image comparison result, and determining a test result of the rendering code file according to the image comparison result; in the test process, the test rendering image to be tested is compared with the reference rendering image with the target rendering effect to determine the test result, so that the requirement on manpower resources in the image rendering effect test process can be reduced, the image rendering effect test cost is saved, and the image rendering effect test speed and accuracy are improved.
