Also, in this specification, the term "and/or" includes any and all combinations of the associated listed items.

The screen mapping method provided by the embodiment of the disclosure can be applied to an application environment of large-screen mapping. The large screen may be a display screen formed by splicing a plurality of display matrixes. Since the aspect ratio of the resolution of the display is fixed, the physical resolution of the large screen is also related to the actual physical lengths of the length and width of the matrix arrangement of the plurality of displays, and the aspect ratio of the physical resolution of the large screen is fixed. The terminal communicates with the large screen through the network, and when the large screen maps the image transmitted by the terminal to the large screen, the aspect ratio of the resolution of the image is inconsistent with the aspect ratio of the physical resolution of the large screen, so that the image is deformed when being mapped to the large screen. The terminal may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and the like.

Based on this, in some embodiments of the present disclosure, as shown in fig. 1, a screen mapping method is provided, which is described by taking the method as an example for being applied to the foregoing terminal, and includes the following steps:

step S10: displaying an original image on a preview display screen, wherein the resolution ratio of the preview display screen is consistent with the ratio of the physical resolution ratio of a target screen, and the target screen is formed by splicing a plurality of split screens.

Specifically, the terminal is further in communication connection with a preview display screen, and the terminal displays the original image on the preview display screen. The original image may be an image with a normal image proportion and without deformation processing, and the original image may be an atlas acquired by the terminal or an image acquired by the terminal in real time through other image acquisition equipment. The preview display screen is a complete display screen, the aspect ratio of the resolution of the preview display screen is consistent with the aspect ratio of the physical resolution of the target screen, and the target screen is the large screen and is formed by splicing a plurality of sub-screens.

Step S20: and acquiring a screenshot image of the original image on the preview display screen according to a set frame frequency.

Specifically, according to a set frame frequency, screenshot is performed on an original image displayed on a preview display screen, so that a screenshot image of the original image is obtained. And the resolution ratio of the screenshot image obtained by screenshot is consistent with the ratio of the preview display screen resolution.

Step S30: and converting the resolution of the screenshot image to be consistent with the resolution of the split screen to obtain a processed image of the screenshot image.

Specifically, the image processing is performed on the screenshot image obtained by screenshot, and the resolution of the screenshot image is converted to be consistent with the resolution of the split screen, so that the processed image of the screenshot image is obtained.

Step S40: and mapping the processed image to the target screen according to the set frame frequency.

Specifically, according to the set frame frequency in screenshot, the processed image of the screenshot image is mapped onto the target screen, so that the target screen can normally display the original image. The mapping mode can be set to be extended by the terminal, not duplicated. So that the preview display screen and the target screen can display different contents, respectively.

For example, as shown in fig. 2, a unit square on the original image is selected as a reference square, and in a normal display state, the aspect ratio of the reference square in the original image is 1:1. the resolution of the split screen may be 1920 × 1080, taking a 4 × 3 matrix as an example, and constitutes the target screen. The physical resolution of the target screen is (1920 × 4) × (1080 × 3), i.e. 7680 × 3240, then the aspect ratio of the physical resolution of the target screen is 7680:3240=64:27. if the original image is directly mapped to the target screen, 1:1 reference square conversion to

Namely, 1:0.75, the reference square is displayed as a rectangle on the target screen, and the original image is known to be deformed.

Displaying the original image on a preview display screen, wherein the resolution aspect ratio of the preview display screen is consistent with the aspect ratio of the physical resolution of the target screen, so that the resolution aspect ratio of the preview display screen is also 64:27, the resolution may be 2560 × 1080. The reference square is still displayed on the preview display with an aspect ratio of 1:1 square. And the terminal acquires a screenshot image of an original image on a preview display screen according to a set frame frequency, wherein the resolution of the screenshot image is 2560 × 1080.

And the terminal compresses the screenshot image to 1920 × 1080 resolution (namely, the resolution is consistent with the resolution of the split screen) by using an image filling method to obtain a processed image of the screenshot image. At this time, the reference square appears to have an aspect ratio of 0.75 in the processed image: 1 is rectangular.

According to the set frame rate, mapping the processing image onto the target screen, wherein the resolution of the processing image is 1920 × 1080, the physical resolution of the target screen is 7680 × 3240, and the processing image is deformed after being mapped onto the target screen, so that the reference square is formed by the following steps of 0.75:1 to 1:1. thus, the aspect ratio of the reference square displayed on the target screen is 1:1, the original image is normally displayed on the target screen at the original scale.

In the screen mapping method, the resolution ratio of the screenshot image is consistent with the physical resolution ratio of the target screen by acquiring the screenshot image of the original image on the preview display screen, the resolution ratio of the screenshot image is processed to be consistent with the split screen resolution of the target screen, and finally the processed image is mapped onto the target screen, so that the target screen can normally display the original image without deformation, the whole mapping process is simple in image processing process, the calculated amount is small, and the original image can be quickly subjected to original scale mapping; meanwhile, the mapping of the original images with various resolutions can be met, and the flexible mapping of the target screen is realized.

In some embodiments of the present disclosure, as shown in fig. 3, the method further comprises:

step S02: and judging whether the resolution aspect ratio of the original image is consistent with the aspect ratio of the physical resolution of the target screen.

Specifically, before the original image needs to be finally mapped to the target screen, the terminal needs to determine the resolution of the original image, the physical resolution of the target screen and the resolution of the split screen. And further judging whether the aspect ratio of the resolution of the original image is consistent with the aspect ratio of the physical resolution of the target screen to obtain a judgment result.

Step S04: and responding to the judgment result of no, and triggering and executing the step of displaying the original image on the preview display screen.

Specifically, as shown in conjunction with the flowchart of fig. 4, in the case where the determination result is no, that is, the aspect ratio of the resolution of the original image does not coincide with the aspect ratio of the physical resolution of the target screen. At this time, the step of displaying the original image on the preview display screen, i.e. the step of performing the above steps S10-S40, is triggered, and finally the processed image is mapped onto the target screen.

Step S06: and triggering to perform the step of mapping the original image onto the target screen in response to the judgment result being yes.

Specifically, in the case where the determination result is yes, that is, the resolution aspect ratio of the original image coincides with the aspect ratio of the physical resolution of the target screen. At this time, the step of mapping the original image onto the target screen is triggered, that is, the original image is directly mapped onto the target screen.

According to the method and the device, the aspect ratio of the resolution ratio of the original image and the aspect ratio of the physical resolution of the target screen is judged before mapping, and the corresponding mapping step is triggered according to the judgment result, so that the final mapping picture is always kept from being deformed, the corresponding mapping step can be automatically executed according to different mapping scenes, and the mapping control is more flexible.

In some embodiments of the present disclosure, the step S10 includes:

Specifically, when the original image is displayed through the preview display screen, the display in a full screen mode or through a display window may be supported. And under the condition that the original image is displayed on the preview display screen in a full screen mode, performing screen capture on the full screen image of the preview display screen during screen capture to obtain a screenshot image. Under the condition that an original image is displayed on a preview display screen through a display window, a screenshot is taken for a picture of the display window during screenshot to obtain a screenshot image, and at the moment, the resolution ratio of the display window is consistent with the ratio of the physical resolution of a target screen.

The preview display screen of the embodiment can support multiple modes such as full screen display and display window display, and correspondingly support a full screen screenshot and a display window screenshot, so that on one hand, it can be ensured that the resolution ratio of an obtained screenshot image is consistent with the ratio of the physical resolution of a target screen under the conditions of the full screen and the display window, and on the other hand, the full screen and the display window can meet display requirements under different scenes, for example, when the preview display screen is displayed through the display window, other areas of the preview display screen can display other information.

In some embodiments of the present disclosure, the set frame rate is equal to or greater than 30 frames per second. In particular, frame rate generally refers to the number of frames or images projected or displayed per second. The set frame frequency may be a fixed frame frequency set according to the mapping requirement, and the capture image and the processing image are acquired according to the fixed frame frequency. The set frame frequency is related to the display fluency of the target screen, and under the condition that the set frame frequency is more than or equal to 30 frames per second, the target screen can more smoothly map the processed image and can support the condition that the original image is a dynamic video.

The present embodiment can satisfy different mapping standards and requirements by setting the frame frequency. When the frame rate is set to 30 frames per second or more, a case where the original image is a moving image can be supported.

It should be understood that, although the steps in the flowcharts related to the embodiments as described above are sequentially displayed as indicated by arrows, the steps are not necessarily performed sequentially as indicated by the arrows.
