Description

[0001] This application belongs to the technical field of touch screens, and particularly relates to a method, device, terminal device, and computer-readable storage medium for constructing an infrared grid. Background Art

[0002] An infrared touch screen is composed of infrared transmitters and receivers installed on the outer frame of the touch screen (generally composed of infrared lamp beads). When the infrared touch screen works, the infrared emission lamp beads continuously emit infrared rays for the infrared receiving lamp beads on the opposite side to receive and record, forming a dense infrared grid composed of infrared rays on the display screen.

[0003] Among them, the infrared rays emitted by the infrared emission lamp beads are not a single infrared straight line, but are composed of multiple light rays with a certain angle of scattering. Different light rays correspond to different infrared receiving lamp beads. However, the number of light rays that the infrared receiving lamp beads can receive is limited. If randomly connected, a large number of holes (i.e., areas not covered by infrared rays) may be formed, resulting in a decrease in the accuracy and stability of the infrared touch screen. Summary of the Invention

[0030] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system architectures, technologies, etc. are presented to thoroughly understand the embodiments of this application. However, those skilled in the art should clearly understand that this application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of this application.

[0031] To better explain the technical solution of this application, the working principle of the infrared touch screen is briefly explained here.

[0032] First, infrared emission lamp beads and infrared reception lamp beads are arranged on the circuit boards at the four edges of the infrared touch screen. Infrared rays are emitted by the infrared emission lamp beads and received by the infrared reception lamp beads to form a vertical and horizontal cross-shaped infrared grid. The infrared touch screen detects and locates the user's touch by continuously scanning whether any infrared rays are blocked by an object.

[0033] Among them, the infrared rays emitted by the infrared emission lamp beads are not a single infrared straight line, but are composed of multiple rays within a certain emission range. Please refer to Figure 1 , Figure 1 which shows a schematic diagram of the infrared emission lamp beads provided by this application. It can be understood that Figure 1 it is only for illustrative purposes, and no limitations are imposed on the positions of the infrared emission lamp beads, the number of infrared emission lamp beads, and the number of infrared rays. As Figure 1 shown, the multiple infrared rays emitted by each infrared emission lamp bead crisscross to form an infrared grid. Among them, the infrared grid formed by the infrared rays is as Figure 2 shown. Please refer to Figure 2 , Figure 2 which shows a schematic diagram of the infrared grid provided by this application. As Figure 2 shown, the black part is the area covered by the infrared rays, while Figure 2 the dotted white parts in it are the gaps (i.e., mesh holes) between the infrared rays. Since the number of rays that the infrared reception lamp beads can receive is limited, if randomly connected, a large number of mesh holes (i.e., areas not covered by infrared rays) may be formed, resulting in a decrease in the accuracy and stability of the infrared touch screen.

[0034] In view of this, the embodiments of this application provide a method, device, terminal device, and computer-readable storage medium for constructing an infrared grid, which can solve the above technical problems.

[0035] Please refer to Figure 3 , Figure 3 which shows a schematic flowchart of a method for constructing an infrared grid provided by this application.

[0036] As Figure 3 shown, the method may include the following steps:

[0037] Step 301, obtain the position information of multiple infrared emission lamp beads corresponding to each infrared reception lamp bead.

[0038] Since the infrared receiving lamp beads have a certain receiving angle, each infrared receiving lamp bead corresponds to multiple infrared transmitting lamp beads. To better understand the correspondence between the infrared receiving lamp beads and the infrared transmitting lamp beads, please refer to Figure 4 , Figure 4 which shows a schematic diagram of the infrared receiving lamp beads and the infrared transmitting lamp beads provided by the present application. As Figure 4 shown, the infrared receiving lamp bead 1 has a certain receiving angle (the two straight lines represent the receiving angle range of the infrared receiving lamp bead 1), and the corresponding transmitting lamp beads for this receiving angle are: the infrared transmitting lamp bead 2, the infrared transmitting lamp bead 3, the infrared transmitting lamp bead 4, and the infrared transmitting lamp bead 5.

[0039] Among them, the acquisition methods of the position information (the position information includes but is not limited to information such as coordinate information or serial numbers for characterizing the positions of the infrared transmitting lamp beads) include the following two types:

[0040] Method ①: Pre-store the serial numbers of the multiple infrared transmitting lamp beads corresponding to different infrared receiving lamp beads. When performing step 301, directly obtain the pre-stored serial numbers to obtain the position information of the multiple infrared transmitting lamp beads corresponding to each infrared receiving lamp bead.

[0041] Method ②: As an optional embodiment of the present application, step 301 includes the following steps 3011 to 3013. Please refer to Figure 5 , Figure 5 which shows a specific schematic flowchart of step 303 in a method for constructing an infrared grid provided by the present application.

[0042] Step 3011, obtain the receiving angle of the infrared receiving lamp bead; the receiving angle refers to the angle formed by the infrared range that the infrared receiving lamp bead can receive.

[0043] Step 3012, according to the receiving angle of the infrared receiving lamp bead and the first coordinate information, calculate the second coordinate information and the third coordinate information of the two intersection points of the two sides of the receiving angle with the touch screen edge.

[0044] As Figure 4 shown, the two sides of the receiving angle and the line segments mapped to the opposite side form a triangle. And the coordinate information of the infrared receiving lamp bead is known, so the second coordinate information and the third coordinate information of the two intersection points of the two sides of the receiving angle with the touch screen edge can be calculated according to the angle-side relationship between the triangles. The calculation process is as follows:

[0045] S = tanθ × L

[0046] where S represents half of the distance between the two intersection points, L is the length of the long side of the screen, and θ is the receiving angle.

[0047] Since this triangle is an isosceles triangle, the first coordinate information and the second coordinate information can be calculated based on the midpoint (the midpoint refers to the point where the midline of the triangle intersects with the opposite side) and the distance between the two intersection points (i.e. S). If the first coordinate information of the infrared receiving lamp bead is (X, Y), the second coordinate information is (X+L, Y+S), and the third coordinate information is (X+L, YS).

[0048] Step 3013: Use the position information of the emitting lamp beads between the second coordinate information and the third coordinate information as the position information of the multiple infrared emitting lamp beads.

[0049] Step 302, according to the positional relationship between the infrared receiving lamp bead and the infrared emitting lamp bead, select a target emitting lamp bead corresponding to each infrared receiving lamp bead from the plurality of infrared emitting lamp beads.

[0050] Due to hardware limitations, infrared receiving lamp beads can only receive a certain amount of infrared rays.

[0051] Among them, Figure 4 As shown, if the infrared ray only receives the infrared rays emitted by the infrared emitting lamp bead 2 and the infrared emitting lamp bead 5 (after reaching the hardware limit, other infrared rays cannot be received), a large number of holes may appear in the middle. Therefore, this embodiment selects the target emitting lamp bead corresponding to each infrared receiving lamp bead from multiple infrared emitting lamp beads according to the positional relationship between the infrared receiving lamp bead and the infrared emitting lamp bead, that is, the infrared receiving lamp bead and the infrared emitting lamp bead on the same straight line are matched as much as possible. The specific matching process is as follows:

[0052] As an optional embodiment of the present application, step 302 includes the following steps 3021 to 3024. Figure 6 , Figure 6 A specific schematic flow chart of step 302 in a method for constructing an infrared grid provided by the present application is shown.

[0053] Step 3021: Use the adjacent first number of infrared receiving lamp beads as a receiving group; wherein the infrared receiving lamp beads in each receiving group are different.

[0054] Step 3022: Use the second number of adjacent receiving groups as a receiving column; wherein the receiving groups in each receiving column are different.

[0055] Step 3023, counting the same infrared emitting lamp beads in all the receiving groups in each of the receiving columns.

[0056] Since different infrared receiving lamp beads in the receiving column may receive a large amount of infrared rays emitted by the same infrared transmitting lamp beads. And different infrared receiving lamp beads receiving the same infrared rays results in the inability to receive the infrared rays emitted by other infrared transmitting lamp beads, thus generating a large number of holes. Therefore, in this example, all the same infrared transmitting lamp beads in each of the receiving groups in each receiving column are counted.

[0057] Among them, the first quantity, the second quantity, and the number of receiving columns can be determined according to the actual application scenario and are not limited here. To better explain the technical solution of this application, this application takes the first quantity as four, the second quantity as three, and the receiving column including the first receiving group, the second receiving group, and the third receiving group as an example to explain the technical solution of this application. It can be understood that the technical solutions corresponding to different first quantities, different second quantities, and different numbers of receiving columns can be obtained by analogy with the technical solution of this application.

[0058] Step 3024, select the target transmitting lamp bead corresponding to each infrared receiving lamp bead among the multiple infrared transmitting lamp beads according to the same infrared transmitting lamp beads.

[0059] In this embodiment, the same infrared transmitting lamp beads are removed from different receiving groups, so that the infrared receiving lamp beads in different receiving groups receive different infrared rays. The specific process is as follows:

[0060] As an optional embodiment of this application, step 3024 includes the following steps A1 to A3. Please refer to Figure 7 , Figure 7 shows a specific schematic flowchart of step 3024 in a method for constructing an infrared grid provided by this application.

[0061] Each of the receiving columns performs the following steps A1 to A3:

[0062] Step A1, sequentially remove the same infrared transmitting lamp beads in the second receiving group until the number of remaining infrared transmitting lamp beads in the second receiving group is the third quantity; use the infrared transmitting lamp beads corresponding to the third quantity as the first target transmitting lamp beads.

[0063] It can be understood that since the second receiving group is the receiving group between the first receiving group and the third receiving group, a large number of infrared receiving lamp beads in the second receiving group correspond to the same infrared transmitting lamp beads.

[0064] Therefore, in this embodiment, in the second receiving group, the same infrared transmitting lamp beads are removed in the order of arrangement until the number of remaining infrared transmitting lamp beads in the second receiving group is the third quantity. Among them, the third quantity is the upper limit value or less than the upper limit value of the number of infrared transmitting lamp beads corresponding to the receiving group, etc., and is not limited here.

[0065] Step A2: Use the infrared emission lamp beads among the multiple infrared emission lamp beads that are before the first sorting as the second target emission lamp beads of the first receiving group.

[0066] Since the first receiving group has a relatively high sorting, it is necessary to select the emission lamp beads with a relatively high sorting as the second target emission lamp beads of the first receiving group, so that receiving groups in different positions correspond to emission lamp beads in different positions. Among them, the first sorting can be preset according to the actual scenario and is not limited here.

[0067] Step A3: Use the infrared emission lamp beads among the multiple infrared emission lamp beads that are after the second sorting as the third target emission lamp beads of the third receiving group.

[0068] Since the third receiving group has a relatively low sorting, it is necessary to select the emission lamp beads with a relatively low sorting as the third target emission lamp beads of the third receiving group, so that receiving groups in different positions correspond to emission lamp beads in different positions. Among them, the second sorting can be preset according to the actual scenario and is not limited here.

[0069] Step 303: Connect each of the infrared receiving lamp beads to the target emission lamp beads corresponding to each of the infrared receiving lamp beads to obtain an initial infrared grid.

[0070] As an optional embodiment of the present application, Step 303 includes the following Steps 3031 to 3033. Please refer to Figure 8 , Figure 8 which shows a specific schematic flowchart of Step 303 in a method for constructing an infrared grid provided by the present application.

[0071] Step 3031: Connect the first target infrared emission lamp bead to the infrared receiving lamp beads in the second receiving group.

[0072] Step 3032: Connect the second target infrared emission lamp bead to the infrared receiving lamp beads in the first receiving group.

[0073] Step 3033: Connect the third target infrared emission lamp bead to the infrared receiving lamp beads in the third receiving group.

[0074] Repeat Steps 3031 to 3033 for each receiving column to obtain the initial infrared grid.

[0075] In this embodiment, the position information of multiple infrared emission lamp beads corresponding to each infrared reception lamp bead is obtained; according to the positional relationship between the infrared reception lamp bead and the infrared emission lamp bead, a target emission lamp bead corresponding to each infrared reception lamp bead is selected from the multiple infrared emission lamp beads; each infrared reception lamp bead is connected to the target emission lamp bead corresponding to each infrared reception lamp bead to obtain an initial infrared grid. In the above solution, an initial infrared grid is formed through the positional relationship between the infrared reception lamp bead and the infrared emission lamp bead. Compared with traditional random connection, since random connection may cause multiple infrared reception lamp beads to correspond to the same infrared emission lamp bead, resulting in uneven infrared distribution. However, in this application, an initial infrared grid is formed through the positional relationship, avoiding multiple infrared reception lamp beads corresponding to the same infrared emission lamp bead, reducing the number of holes, and thus improving the accuracy and stability of the infrared touch screen.

[0076] Optionally, on the basis of the above Figure 1 shown embodiment, after step 303, the following steps are further included. Please refer to Figure 9 , Figure 9 which shows a schematic flowchart of another method for constructing an infrared grid provided by this application.

[0077] Step 301, obtain multiple infrared emission lamp beads corresponding to each infrared reception lamp bead.

[0078] Step 302, according to the positional relationship between the infrared reception lamp bead and the infrared emission lamp bead, select a target emission lamp bead corresponding to each infrared reception lamp bead from the multiple infrared emission lamp beads.

[0079] Step 303, connect each infrared reception lamp bead to the target emission lamp bead corresponding to each infrared reception lamp bead to obtain an initial infrared grid.

[0080] Step 801, repeatedly execute the step of obtaining the position information of multiple infrared emission lamp beads corresponding to each infrared reception lamp bead and subsequent steps to obtain multiple initial infrared grids.

[0081] Step 802, calculate the fourth quantity of preset holes in each initial infrared grid; the preset hole refers to a hole of a preset size; the hole refers to an area not covered by infrared rays.

[0082] For the preset hole, this embodiment provides two calculation methods:

[0083] The first calculation method: As Figure 2As shown, since the colors of the holes and the infrared rays in the infrared ray grid map are often different, the number of white pixels in the infrared ray grid maps corresponding to multiple initial arrangement manners can be counted, and the initial arrangement manner corresponding to the infrared ray grid map with the fewest white pixels is used as the target arrangement manner.

[0084] The second calculation method: As an optional embodiment of the present application, step 802 includes the following steps 8021 to step 8020. Please refer to Figure 10 , Figure 10 shows a specific schematic flowchart of step 802 in a method for constructing an infrared ray grid provided by the present application.

[0085] Step 8021, traverse the initial infrared ray grid from the first long side of the touch screen to the second long side of the touch screen at a first preset step length through a first straight line parallel to the long side of the touch screen.

[0086] Step 8022, during the traversing process, count the first intersections between each position of the first straight line and the infrared rays.

[0087] Step 8023, calculate the first distances between adjacent first intersections.

[0088] Step 8024, count the fifth quantity of the first distances greater than or equal to the threshold.

[0089] Step 8025, traverse the initial infrared ray grid from the first wide side of the touch screen to the second wide side of the touch screen at a second preset step length through a second straight line parallel to the wide side of the touch screen.

[0090] Step 8026, during the traversing process, count the second intersections between each position of the second straight line and the infrared rays.

[0091] Step 8027, calculate the second distances between adjacent second intersections.

[0092] Step 8028, count the sixth quantity of the second distances greater than or equal to the threshold.

[0093] Step 8029, add the fifth quantity and the sixth quantity to obtain the seventh quantity.

[0094] Step 8020, use the seventh quantity as the fourth quantity of the preset holes.

[0095] For a better explanation of the calculation process, please refer to Figure 11 , Figure 11 shows a schematic diagram of infrared ray grid traversal provided by the present application. As Figure 11As shown, line a is the first line and line b is the second line. The terminal device traverses from the first long side of the touch screen to the second long side in the infrared grid diagram along the first line parallel to the long side of the touch screen with a first preset step length (e.g., one millimeter). During the traversal, the first intersections between the first line and the infrared rays at each location are counted, and the first distances between adjacent first intersections are calculated. The fifth quantity where the first distance is greater than or equal to the threshold is counted (thus ending the traversal of the long side of the touch screen).

[0096] Through the second line parallel to the short side of the touch screen, traverse from the first short side of the touch screen to the second short side in the infrared grid diagram with a second preset step length (the second preset step length can be the same as or different from the first preset step length). During the traversal, the second intersections between the second line and the infrared rays at each location are counted. The second distances between adjacent second intersections are calculated. The sixth quantity where the second distance is greater than or equal to the threshold is counted. The fifth quantity and the sixth quantity are added together to obtain the fourth quantity of the preset mesh holes.

[0097] Step 803: Use the initial infrared grid with the fewest preset mesh holes among the multiple initial infrared grids as the target infrared grid.

[0098] In this embodiment, by repeatedly executing the step of obtaining the position information of the multiple infrared emitting lamp beads corresponding to each infrared receiving lamp bead and the subsequent steps, multiple initial infrared grids are obtained. Calculate the fourth quantity of the preset mesh holes in each of the initial infrared grids; the preset mesh hole refers to a mesh hole of a preset size; the mesh hole refers to the area not covered by the infrared rays. Use the initial infrared grid with the fewest preset mesh holes among the multiple initial infrared grids as the target infrared grid. Through the above solution, the number of mesh holes is further reduced, thereby improving the accuracy and stability of the infrared touch screen.

[0099] As Figure 12 This application provides a device 12 for constructing an infrared grid. Please refer to Figure 12 , Figure 12 shows a schematic diagram of a device for constructing an infrared grid provided by this application. As Figure 12 shown, a device for constructing an infrared grid includes:

[0100] An acquisition unit 121 for acquiring the position information of the multiple infrared emitting lamp beads corresponding to each infrared receiving lamp bead.

[0101] A selection unit 122 for selecting the target emitting lamp bead corresponding to each infrared receiving lamp bead from the multiple infrared emitting lamp beads according to the positional relationship between the infrared receiving lamp bead and the infrared emitting lamp bead.

[0102] A connection unit 123 is used to connect each of the infrared receiving lamp beads to the target emitting lamp bead corresponding to each of the infrared receiving lamp beads, so as to obtain an initial infrared grid.

[0103] An apparatus for constructing an infrared grid provided by this application obtains the position information of a plurality of infrared emitting lamp beads corresponding to each infrared receiving lamp bead; selects the target emitting lamp bead corresponding to each infrared receiving lamp bead from the plurality of infrared emitting lamp beads according to the positional relationship between the infrared receiving lamp bead and the infrared emitting lamp bead; and connects each infrared receiving lamp bead to the target emitting lamp bead corresponding to each infrared receiving lamp bead to obtain an initial infrared grid. In the above solution, an initial infrared grid is formed through the positional relationship between the infrared receiving lamp bead and the infrared emitting lamp bead. Compared with traditional random connection, since random connection may cause multiple infrared receiving lamp beads to correspond to the same infrared emitting lamp bead, the infrared distribution is uneven. However, in this application, an initial infrared grid is formed through the positional relationship, avoiding multiple infrared receiving lamp beads corresponding to the same infrared emitting lamp bead, reducing the number of holes, and thus improving the accuracy and stability of the infrared touch screen.
