Detailed Description
The following detailed description of the disclosed embodiments will be made in conjunction with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Before introducing the method for judging the abnormal slice image of the special-shaped LED display screen provided by the present disclosure, a target application scenario related to each embodiment in the present disclosure is first introduced, where the target application scenario includes an electronic device, and the electronic device may be, for example, a personal computer, a notebook computer, a tablet computer, and the like.
Fig. 1 is a flowchart illustrating a method for determining an abnormal slice of an irregular LED display screen according to an exemplary embodiment, which is applied to an electronic device, as shown in fig. 1, and includes:
in step 101, according to the shape and resolution of the special-shaped LED display screen, a picture to be played is sliced to obtain a first sliced picture.
Exemplarily, the shaped LED display screen generally refers to an unconventionally shaped LED display screen, such as a spherical LED display screen, a letter-shaped LED display screen, a fan-shaped LED display screen, and the like. The special-shaped LED display screen in the embodiment of the invention is preferably a fan-shaped LED display screen and other LED display screens which show a certain proportional relation with the shape and size of the display area. The picture to be played is determined according to a video signal source issued by a sending card, the picture to be played is generally set according to the shape (rectangle) of an LED display screen according to the conventional rule, and the video signal source is a standard signal source. According to the resolution of the special-shaped LED display screen, a rectangular picture to be played is sliced into a certain number of first slice pictures (in general, each first slice picture is the same in size and shape and is rectangular).
It should be noted that the LED display screen is composed of a plurality of LED boxes with the same resolution, and the sum of the resolution of all the LED boxes is the resolution of the LED display screen. The video signal source sent down in the transmitting card is usually determined according to the resolution of the display screen of the LED for displaying the video signal source.
In step 102, a first grid line corresponding to the first cut picture is generated according to the shape of the special-shaped LED display screen.
Illustratively, the first grid line is generated according to the shape of the special-shaped LED display screen and can be set to be any shape corresponding to the shape of the special-shaped LED display screen. The first grid line and the first slice screen exist independently, and shape conversion is performed on the display area by the following step 103.
In addition, a certain corresponding relation exists between the number of the first grid lines and the number of the first slice pictures.
In step 103, shape transformation of the first grid lines and the first slice image in equal proportion is performed according to the shape of the special-shaped LED display screen, and second grid lines and a second slice image are obtained on a display area corresponding to the special-shaped LED display screen.
For example, in order to clearly present the display content corresponding to the second slice on the special-shaped LED display screen, the shape of the second slice needs to be adjusted to the shape of the special-shaped LED display screen. That is, according to the shape of the special-shaped LED display screen, each first slice is subjected to shape conversion in an equal proportion and converted into a second slice.
In addition, in order to determine the final display effect of the picture to be played on the special-shaped LED display screen according to the grid lines, the second slice picture which is consistent with the shape of the special-shaped LED display screen is generated, meanwhile, the first grid lines are subjected to shape transformation in an equal proportion, and the second grid lines are generated.
It should be noted that, in the embodiment of the disclosure, the shape of the first slice image is transformed in the display area of the display interface of the electronic device, so that a worker can process and observe the transformed second slice image and the second grid lines conveniently, the first grid lines and the second grid lines are in a mapping relationship, and the shape of the second grid lines may be preferably a square or other rectangular grid with different lengths and widths.
In step 104, the second slice is tiled on the display area according to a preset frame tiling strategy, and the second grid line moves correspondingly along with the second slice in the tiling process.
Illustratively, the picture splicing strategy is generated according to the display content of the picture to be played, the shape and resolution of the special-shaped LED display screen, the number of the second slices, and the display content of each second slice, that is, the second slices are spliced in the display area according to the picture splicing strategy, and then the spliced second slices are sent to the special-shaped LED display screen for display, so that the display content in the picture to be played is presented on the special-shaped LED display screen.
It should be noted that there is a certain correspondence between the second grid lines and the second slice, and during the stitching process, the movement of each second slice drags the corresponding movement of the second grid line corresponding to the second picture.
It can be understood that after the spliced second slice image is sent to the special-shaped LED display screen, the worker is required to manually adjust and splice the spliced second slice image on the special-shaped LED display screen again.
In step 105, if there is an abnormality in the connection relationship and/or the distance relationship of the second grid lines between the spliced second slices, the second slice corresponding to the second grid line having the abnormality is determined to be an abnormal slice.
For example, for the second sliced picture after being spliced on the display area or for the display picture (the display content in the picture to be played) presented on the special-shaped LED display screen, whether the second grid lines are abnormal or not may be determined according to the connection relationship and the distance relationship between the second grid lines. And if the abnormal condition exists, determining the second slice picture corresponding to the abnormal second grid line as the abnormal slice picture according to the specific position of the abnormal condition in the connection relation and/or the distance relation of the second grid line. Therefore, in the plurality of second slicing images, the staff can determine one or more abnormal slicing images in time so as to investigate the reason of the abnormality and adjust the second slicing images with the abnormality on the display area.
It is understood that the distance relationship refers to a ratio of a visual length of each mesh observed at a preset fixed observation point to a distance between the observation point and a mesh line.
Fig. 2 is a flow chart of a slicing method according to fig. 1, as shown in fig. 2, the step 101 comprising:
in step 1011, a picture slicing strategy is determined according to the resolution of the picture to be played and the special-shaped LED display screen.
The picture slicing strategy comprises the times of slicing the picture to be played and the size of each first slice picture after slicing processing.
In step 1012, the to-be-played picture is sliced according to the picture slicing policy, and a preset number of first sliced pictures are obtained.
Illustratively, the number of times the picture to be played needs to be sliced and the size of each first sliced picture after slicing processing are determined according to the resolution of the special-shaped LED display screen and the display content of the picture to be played. For example, according to the resolution of the special-shaped LED display screen, 4 times of slices are performed on a rectangular picture to be played, and 5 first slice pictures that are rectangular and have the same size and shape are obtained.
Fig. 3 is a flow chart of a method of shape transformation according to fig. 1, as shown in fig. 3, the step 103 comprising:
in step 1031, the display area is determined according to the shape of the LED display screen.
Wherein the display area comprises at least one display sub-area, and the number of the display sub-areas is the same as that of the second slice pictures.
In step 1032, the first slice is subjected to shape transformation in equal proportion, and a second slice with the same shape as the special-shaped LED display screen is obtained.
In step 1033, the first grid lines are subjected to shape transformation in an equal proportion to obtain second grid lines corresponding to the second slice.
In step 1034, each of the second slices and the corresponding second grid lines are placed in each of the display sub-regions, respectively.
By way of example, a display area with the same shape as the special-shaped LED display screen is determined on a display interface of the electronic device, so that a worker can conveniently observe the first grid lines and the first slice picture on the display area to perform a process of generating second grid lines and a second slice picture through shape transformation, and perform a process of splicing the second slice picture. Each second slice is located in each display sub-region of the display region, and each display sub-region has the same shape and size as each second slice.
It can be understood that the display area is located on the display interface of the electronic device, and therefore, the display area and the special-shaped LED display screen have the same shape and show an equal-scale size relationship, and in order to facilitate setting and observing the second slice in the display area, it is necessary to first reduce the second slice in an equal-scale manner and then show the second slice on the display area. And before the display content corresponding to the picture to be played is presented on the special-shaped LED display screen, amplifying each second slice picture according to the same proportion so that the size of each second slice picture can be adapted to the display resolution of the special-shaped LED display screen.
Fig. 4 is a flowchart of an abnormality determination method according to fig. 1, where step 104, as shown in fig. 4, includes:
in step 1041, an observation image of the special-shaped LED display screen is obtained at a preset observation point.
Illustratively, the preset observation point generally refers to a position where a display effect (i.e., an observation image) of the special-shaped LED display screen is obtained, and the observation point may be one or more. The observation image of the special-shaped LED display screen is obtained by shooting the special-shaped LED display screen through an image acquisition device (such as a camera) at an observation point, or is obtained by shooting a second tangent plane picture spliced on the display area through the image acquisition device at the observation point. In this manner, the following steps 1042 to 1045 determine whether or not an abnormal slice image exists from the observation image.
In step 1042, it is determined whether there is an abnormality in the connection relationship of the second mesh lines in the observed image.
In step 1043, if there is an abnormality in the connection relationship of the second grid lines, the second slice screen corresponding to the second grid line having the abnormality is determined to be an abnormal slice screen.
Specifically, if the connection relationship of the second grid lines is abnormal, determining an abnormal connection position where the connection relationship between the second grid lines is abnormal; determining a third slice at the abnormal connection position; setting a third slice image with abnormity in second grid line connection relations between two adjacent third slice images as a second slice image corresponding to the second grid line with abnormity in the third slice image; the second slice corresponding to the second grid line where the abnormality exists is determined as the abnormal slice.
For example, if there is a case in the observed image that the second grid lines cannot be connected together at the connecting edge of the second slice (i.e., there is an abnormality in the connection relationship), the second slice corresponding to the connecting edge may be an abnormal slice. For further determination, an abnormal connection position where the connection relationship is abnormal is determined, a second slice at the abnormal connection position is determined (normally, the abnormal connection point at the abnormal connection position is located on the connection edge of the second slice), and the second slice at the abnormal connection position is set as a third slice. And judging whether the connection relation between each third slice image and the adjacent third slice image is abnormal or not, and determining the third slice image with the abnormal second grid line connection relation between the adjacent two third slice images as the second slice image corresponding to the abnormal second grid line.
In step 1044, it is determined whether there is an anomaly in the far-near relationship of the second grid lines in the observed image.
In step 1045, if there is an abnormality in the distance relationship of the second grid lines, the second slice screen corresponding to the second grid line having the abnormality is determined to be an abnormal slice screen.
Illustratively, in the embodiment of the present disclosure, the actual length of each grid in the second grid line is equal, the visual length (the length displayed by each grid in the observation image obtained at the observation point) should be inversely proportional to the distance between the position of the grid and the observation point, and the ratio (i.e., the distance relationship) is a fixed value. And if it is determined that a second grid line with a distance relation different from the fixed numerical value exists in the observation picture, the second slice picture where the second grid line is located is the abnormal slice picture.
In addition, the worker can stand at the observation point to observe the display effect on the special-shaped LED display screen or the spliced second slice picture on the display area, and at the moment, the image displayed in the retina of the worker is the observation image. And the staff determines whether the connection relation and/or the distance relation of the second grid lines are abnormal or not according to the observed observation image.
Fig. 5 is a schematic diagram illustrating an abnormality determination, and fig. 5 includes 5 second slices, namely, a second slice 1, a second slice 2, a second slice 3, a second slice 4, and a second slice 5. If there is an abnormality in the connection relationship between the second grid line in the second slice 3 and the second grid line in the second slice 2, there is an abnormality in the connection relationship between the second grid line in the second slice 3 and the second grid line in the second slice 4, and there is no abnormality in the connection relationship between the second grid line in the second slice 1 and the second slice 2, and between the second slice 4 and the second grid line in the second slice 5, it is possible to determine that only the second slice 3 is an abnormal slice.
