Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.
First, in the present exemplary embodiment, there is provided a method of determining an offset of a display unit, as shown with reference to fig. 1, the method including the following steps S101 to S104:
step S101, acquiring a display image of a display unit to be tested which is lighted according to a preset lighting rule;
step S102, determining the position coordinates of a first lamp point in the display image;
step S103, acquiring position coordinates of a second lamp point in a sample image corresponding to a sample display unit, wherein the position of the second lamp point in the sample display unit is the same as the position of the first lamp point in the display unit to be detected;
and step S104, determining the offset position of the display unit to be detected relative to the sample display unit according to the position coordinates of the first lamp point and the position coordinates of the second lamp point.
According to the method, the position coordinates of the first lamp point in the display image of the display unit to be detected are determined, then the second lamp point with the same position as the first lamp point is found in the sample display unit, the position coordinates of the second lamp point are obtained, finally the offset of the first lamp point can be determined by comparing the position coordinates of the first lamp point and the second lamp point, and therefore the offset generated by the lighting position of the display unit to be detected is determined.
Optionally, the offset position determined by the method of the embodiment of the present application may be applied in various aspects. For example, determining the offset position can perform lamp positioning on the display unit to be detected, can also correct the collected data of the camera, and can also be used for detecting the appearance of a product.
Hereinafter, the respective steps of the above-described method in the present exemplary embodiment will be described in more detail with reference to fig. 1 to 3.
In the present invention, the display unit may be an LED display module, and each LED display module includes a plurality of light emitting devices, i.e., light points.
In one embodiment, one LED display module can be selected from a plurality of LED display modules forming a whole LED screen to serve as a sample display unit, and the other LED display modules serve as display units to be tested. In order to make the finally determined offset position of the display unit to be detected relative to the sample display unit more accurate, the lamp panel types of the sample display unit and the display unit to be detected are ensured to be the same. Specifically, the same lamp panel types may include the same batch, the same size, the same number of lamp points, and the same spacing and arrangement between the lamp points in the two lamp panels.
In step S101, the preset lighting rule may be a lighting display image program set in advance. For example, in one embodiment, at least one of the four corners of the display unit under test may be turned on, only the center light of the display unit under test may be turned on, or both the four corners and the center light of the display unit under test may be turned on. Of course, in other embodiments, the number of the lamp points at other positions may be N, or even at least one lamp point of the display unit to be tested may be sequentially turned on according to a predetermined turn-on sequence, where each turn-on corresponds to one display image. The above examples do not represent the limitation of the lighting rule in the present invention, as long as at least one lamp on the display unit to be tested is ensured to be lighted, so as to avoid the situation that the lamp cannot be lighted due to being a dead lamp and thus cannot display an image.
In one embodiment, the preset lighting rule may be obtained in response to a trigger command, and specifically, the preset lighting rule includes a position and a number of lamp points to be lit. For example, in one example, the indication lights the display unit for the 3 rd, 4 th, 5 th light point from left to right in the first row and the 4 th light point from left to right in the third row. Of course, in other examples, other numbers and other positions of the lamp points can be indicated to be lighted, and the specific indication information is not limited in the present invention and can be set as required according to actual situations.
In step S102, the display image may be captured by taking a picture displayed on the display unit to be tested using a CCD (charge coupled device) camera. The position coordinates of the first light point in the display image may be coordinates of a pixel where the first light point is located in the display image.
In one embodiment, referring to fig. 2, in the image captured by the CCD camera, the position of a single light spot is formed by a bright spot and a plurality of dark spots on the periphery, i.e. a circled range in fig. 2. Therefore, to determine the position coordinates of the first light point in the display image, the optical parameters of the first light point are first obtained, and then the position coordinates of the first light point are calculated according to the optical parameters.
Specifically, the light parameter of the lamp point may be a light intensity value, a brightness value, a chromaticity value, or other parameter values, and the above process is described by taking a brightness value as an example in this embodiment. In the process of collecting and analyzing display image data, when the brightness value of a certain lamp point is detected, comparing the brightness value with a preset detection brightness threshold value, and when the brightness value is smaller than the detection brightness threshold value, determining that the lamp point is not lightened; when the brightness value is larger than the detection brightness threshold value, the lamp point is considered to be lighted. After the light point is confirmed to be lighted, a point with the highest brightness value at the position of the light point in the picture is taken as a circle center, a point with the lowest brightness value around the circle center is taken as a boundary circle, and the coordinate position of the circle on the CCD sensor is the coordinate value corresponding to the light point.
In step S103, the position coordinates of the second light point in the sample image may be coordinates of a pixel in the sample image where the second light point is located.
In one embodiment, before obtaining the position coordinates of the second light point in the sample image corresponding to the sample display unit, the position coordinates of each light point in the sample image corresponding to the sample display unit also need to be obtained. Specifically, the process of obtaining the position coordinate of each lamp point in the sample image corresponding to the sample display unit is the same as the method of displaying the position coordinate of the first lamp point in the image. The light parameter of each light point in the sample image is obtained, and then the coordinate value corresponding to each light point is determined according to the light parameter of each light point. Similarly, the light parameter may be a light intensity value, a luminance value, a chrominance value, or other parameter value. And when the position coordinates of each lamp point in the sample image corresponding to the sample display unit are obtained, the position coordinates of the second lamp point can be directly found from the position coordinates.
Since each display unit is transported to a designated position by the fully automatic apparatus and the placing direction is fixed, the deviation between each display unit and the previous display unit is slight, and only slight translation of the whole is generated relative to the previous display unit. Therefore, in step S104, after determining the offset position of the display unit to be measured relative to the sample display unit according to the position coordinates of the first light point and the position coordinates of the second light point, the position coordinates of each light point in the display unit to be measured can be determined according to the offset position and the position coordinates of each light point in the sample image corresponding to the sample display unit.
Specifically, in one example, for example, if the calculated position offset value is (0.02, 0.1), the position coordinates of each lamp point in the display unit can be obtained by adding the position offset value to the position coordinates of each lamp point in the sample display unit. Therefore, the position offset correction algorithm of each lamp point in the display unit provided by the invention is a simple numerical addition and subtraction method, compared with the process of correcting the lamp points in each display unit to be detected by performing circle-by-circle positioning one by one, the calculation is simple and fast, the offset correction time of the LED unit is further shortened, and the operation amount in the correction process is reduced.
In one embodiment, when the number of the first lamp points is one, the offset position is a difference between position coordinates of the first lamp point and the corresponding second lamp point. For example, referring to fig. 3, fig. 3(a) shows the display unit 110 to be measured, where the position of the first light point is the 3 rd light point from left to right in the first row of the lamp panel, that is, the position encircled by the white circle in fig. 3(a), the determined coordinate value is (3.02, 15.1), and correspondingly, the coordinate value (3, 15) of the position offset value calculated by finding the coordinate value (3.02, 15.1) - (3, 15) in the sample display unit 120 in fig. 3(b) at the 3 rd light point from left to right in the first row of the lamp panel, that is, the position encircled by the white circle in fig. 3(b) is (0.02, 0.1). Of course, the above calculation processes and values are only examples and do not represent a limitation to the present invention.
In one embodiment, if the number of the first light points is multiple, the multiple offset amounts may be determined according to the position coordinates of multiple first light points and the corresponding position coordinates of multiple second light points. And then determining the final offset position according to the average value of the plurality of offset values. For example, the number of the first light points is 2, where the first light point is the 3 rd light point from left to right in the first row of the lamp panel, the coordinate value is (3.02, 15.1), the coordinate value (3, 15) of the corresponding light point located in the first row of the lamp panel from left to right in the sample display unit is (3.02, 15.1) - (3, 15) ═ 0.02, 0.1 is calculated as the first position deviation value. The second first light point is the 3 rd light point from left to right in the fifth row of the lamp panel, the coordinate value is (3.04, 10.3), the coordinate value (3, 10) of the corresponding light point located in the fifth row of the lamp panel from left to right in the sample display unit is (3.04, 10.3) - (3, 10) ═ 0.04, 0.3. The final calculated offset position is the average (0.03, 0.2) of the two offset values (0.02, 0.1) and (0.04, 0.3).
It is noted that although the steps of the methods of the present invention are depicted in the drawings in a particular order, this does not require or imply that the steps must be performed in this particular order, or that all of the depicted steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc. Additionally, it will also be readily appreciated that the steps may be performed synchronously or asynchronously, e.g., among multiple modules/processes/threads.
