Description

Technical Field

[0001] This invention relates to the field of infrared touch technology, and in particular to a method, apparatus, terminal device and storage medium for arranging LED beads in an infrared touch frame. Background Technology

[0002] The basic principle of an infrared touch frame is to install infrared emitters and receivers on opposite sides of the touchscreen. A pair of emitters and receivers forms a ray with known coordinates at both ends. All the rays formed by the infrared emitters and receivers within the touch frame constitute an infrared grid. When an external object, such as a stylus or finger, touches the touchscreen within the frame, it blocks some rays. When the touched point needs to be located, the infrared touch system calculates the touch point based on the blocked rays. The density of the infrared ray grid directly affects the positioning accuracy during calculation. Uneven arrangement of the LEDs within the infrared touch frame leads to an uneven distribution of the infrared ray grid, thus affecting the positioning accuracy. Currently, the arrangement of infrared LEDs is mainly done manually, which results in uneven distribution of the infrared ray grid. When unevenness exists, the LED arrangement needs to be manually adjusted, leading to low efficiency. Summary of the Invention

[0042] Figure 1 This is a flowchart illustrating a method for arranging LED beads in an infrared touch frame according to an embodiment of the present invention.

[0043] Figure 2 This is a schematic diagram of the structure of an infrared touch frame LED bead arrangement device provided in an embodiment of the present invention. Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] To better understand this invention, it's important to understand that the basic principle of an infrared touch frame is that infrared emitters and receivers are installed on opposite sides of the touchscreen. These emitters and receivers form a ray with known coordinates at both ends, and all these infrared rays together constitute a light grid. Within this light grid, when a stylus or finger touches the touchscreen, it blocks some rays. The infrared touch system associated with the infrared touch frame calculates the touch point based on the blocked rays, thus determining the location clicked by the stylus. Therefore, the density of the infrared ray grid directly affects the positioning accuracy and the minimum discernibility of the stylus. The infrared ray grid density is directly proportional to the number of infrared emitters and receivers, but increasing the number of infrared lights increases cost. Another factor affecting the infrared ray grid density is the arrangement of the infrared lights. Infrared lights in the infrared emitter frame are not evenly spaced, resulting in areas with high light density and areas with low light density. The purpose of this invention is to improve the uniformity of the light grid by adjusting the arrangement of the infrared lights without increasing the number of lights, i.e., without increasing hardware costs. The uniformity of an optical network is primarily determined by the voids in the network and the uniformity of light distribution.

[0046] like Figure 1 The image shows a method for arranging LED beads in an infrared touch frame according to an embodiment of the present invention, comprising:

[0047] Step S1: Obtain the initial LED arrangement scheme;

[0048] Step S2: Evaluate the initial optical network corresponding to the initial LED arrangement scheme according to the optical network quality evaluation method, and generate the optical network evaluation result;

[0049] Step S3: When the evaluation result of the optical network meets the evaluation threshold, the initial lamp bead arrangement scheme is taken as the target lamp bead arrangement scheme;

[0050] Step S4: When the evaluation result of the optical network does not meet the evaluation threshold, perform the lamp bead arrangement adjustment operation;

[0051] For step S1, an initial LED arrangement scheme is determined by uniformly distributing the LEDs, and an initial light grid is generated based on the initial LED arrangement scheme.

[0052] For step S2, in a preferred embodiment, evaluating the initial optical network corresponding to the initial LED arrangement scheme according to the optical network quality evaluation method and generating an optical network evaluation result includes: dividing the initial optical network into several regions and determining the number of light rays in each region; generating an optical network array based on the several regions and the number of light rays in each region; determining the optical network distribution uniformity based on the standard deviation and mean of the optical network array; and generating an optical network evaluation result based on the optical network distribution uniformity.

[0053] Specifically, the quality of the generated initial optical grating is evaluated. The uniformity of the optical grating distribution is a crucial indicator of its quality. The more uniform the distribution of the optical grating across the entire touchscreen, the higher its quality. To evaluate the initial optical grating, the touchscreen is first divided into m*n regions, and the number of light rays passing through each region is counted, forming an optical grating array of length m*n. The mean and standard deviation of this array are then calculated. A higher mean and a smaller standard deviation both indicate better uniformity. The uniformity of the optical grating distribution is determined by calculating the standard deviation and mean of the optical grating array, using the following formula:

[0054] Distribute_quality=a*mean1+b*std1

[0055] Where Distribute_quality represents the uniformity of the optical network distribution; mean1 represents the mean of the optical network array; std1 represents the standard deviation of the optical network array; a and b are weight parameters, where 1>a>0, -1 <b<0。

[0056] In a preferred embodiment, after determining the uniformity of the optical network distribution, the method further includes: acquiring void information of the initial optical network; wherein the void information includes: the number of voids and the area of ​​each void; determining the total void area of ​​the initial optical network based on the number of voids and the area of ​​each void; determining the optical network void metric value based on the total void area, void standard deviation, and void mean of the initial optical network; and generating the optical network evaluation result includes: generating the optical network evaluation result based on the optical network distribution uniformity and the optical network void metric value.

[0057] Specifically, in evaluating optical network quality, the optical network hole metric is another important indicator. This metric is used to evaluate the number, area, and distribution of larger holes in the optical network. In an optical network, the grid is polygonal; we calculate the grid size using the maximum diagonal length. In the entire optical network, polygonal grids with a maximum diagonal length greater than a preset threshold are considered holes, generating a hole list and corresponding hole information. This hole information includes: the number of holes, the area of ​​each hole, and the distribution of each hole. The hole area and distribution can be determined using coordinates. Based on the number of holes and the area of ​​each hole in the hole list, the total hole area of ​​the network can be determined. Similarly, the standard deviation and mean of the holes are calculated. Then, based on the total hole area, standard deviation, and mean of the holes, the optical network hole metric is determined. The corresponding calculation formula is as follows:

[0058] Hole_quality=c*mean2+d*std2+e*area

[0059] Where Hole_quality represents the hole metric of the optical network; mean2 represents the mean hole value; std2 represents the standard deviation of the hole value; area represents the total hole area; c, d, and e are weighting parameters, where -1 <c<0,-1<d<0,-1<e<0。

[0060] The optical network evaluation results are generated based on the optical network distribution uniformity and the optical network hole metric. The corresponding calculation formulas are as follows:

[0061] Quality=α*Distribute_quality+β*Hole_qualit

[0062] Where Qulity represents the evaluation result of the optical network; α and β are two weight parameters, where 0 < α < 1, 0 < β < 1, and α + β = 1.

[0063] In this embodiment of the invention, α and β can be initially set to 0.5 respectively. If the phenomenon of local voids is found to be obvious, β can be increased, and vice versa. If there is no obvious trend of local voids, it can be kept at 0.5.

[0064] For step S3, when the optical network evaluation result meets the evaluation threshold, the initial lamp bead arrangement scheme is taken as the target lamp bead arrangement scheme. The evaluation threshold can be an index of the optical network evaluation result set manually.

[0065] For step S4, when the evaluation result of the optical network does not meet the evaluation threshold, the lamp arrangement adjustment operation is performed.

[0066] In a preferred embodiment, after determining the maximum void in the optical network corresponding to the initial LED arrangement and identifying the LEDs associated with the maximum void as LEDs to be adjusted, the method further includes: identifying LEDs whose spacing from the LEDs to be adjusted is less than a preset spacing as LEDs to be adjusted.

[0067] The lamp bead arrangement adjustment operation specifically includes:

[0068] Step S401: Obtain the initial LED arrangement scheme;

[0069] Step S402: Determine the maximum hole in the optical mesh corresponding to the initial LED arrangement scheme, and take the LEDs related to the maximum hole as LEDs to be adjusted, and add the determined LEDs to be adjusted to an adjustment queue;

[0070] Step S403: Select LEDs with a spacing of less than m (i.e., the preset spacing) from the LEDs to be adjusted as LEDs to be adjusted, and add the newly added LEDs to the adjustment queue; wherein, the preset spacing m is related to the area size when dividing the screen into equal areas during the evaluation of optical network quality.

[0071] Step S404: Generate a Gaussian random number for each LED bead in the adjustment queue, and adjust the corresponding LED bead position according to each Gaussian random number to generate an adjusted LED bead arrangement scheme; specifically, adjust the LED bead according to the Gaussian random number of each LED bead to be adjusted. If the Gaussian random number is positive, adjust to the right (up); if it is negative, adjust to the left (down). The mean of the Gaussian distribution is zero, and the standard deviation is proportional to the size of the hole. The corresponding standard deviation calculation formula is as follows:

[0072] std3 = hole_size * δ

[0073] Where std3 represents the standard deviation of the Gaussian distribution of the LED beads to be adjusted; hole_size represents the hole size; δ is a custom parameter that can be set to 1 and adjusted based on actual performance during the calculation process.

[0074] For each cavity containing an LED bead to be adjusted, the LED bead is adjusted according to a Gaussian distribution (0, hole_size*δ) to reduce the cavity area and evenly distribute the relevant LED beads.

[0075] Step S405: Evaluate the optical network corresponding to the adjusted LED arrangement scheme according to the optical network quality evaluation method, and generate the corresponding optical network evaluation results;

[0076] Step S406: When the evaluation result of the optical network corresponding to the adjusted LED arrangement scheme meets the evaluation threshold, the adjusted LED arrangement scheme is taken as the target LED arrangement scheme.

[0077] Step S407: If the evaluation result of the optical network corresponding to the adjusted LED arrangement scheme does not meet the evaluation threshold, the adjusted LED arrangement scheme is used as the initial LED arrangement scheme, and the process returns to step S401 to perform the LED arrangement adjustment operation until an LED arrangement scheme that meets the evaluation requirements of step S406 is obtained.

[0078] In a preferred embodiment, the method further includes: generating a list of LED arrangement schemes; storing each LED arrangement scheme and its corresponding optical network evaluation result in an array in the list of LED arrangement schemes; wherein the list of LED arrangement schemes is sorted from largest to smallest according to the optical network evaluation result; and selecting several LED arrangement schemes from the head of the list of LED arrangement schemes for visualization.

[0079] Specifically, a list of LED chip arrangement schemes is generated. Each time a fiber optic network evaluation result is obtained, the corresponding LED chip arrangement scheme and the evaluation result are stored in an array in the LED chip arrangement scheme list. This results in a list of LED chip arrangement schemes containing several fiber optic network evaluation results, which are then arranged in descending order of evaluation result. The top n schemes with the highest fiber optic network evaluation results are selected and displayed to the user visually, allowing for quick and intuitive selection of the desired LED chip arrangement scheme.
