Detailed Description
It should be noted that step numbers (letter or number numbers) are used to refer to some specific method steps in the present invention only for the purpose of convenience and brevity of description, and the order of the method steps is not limited by letters or numbers in any way. It will be clear to a person skilled in the art that the order of the steps of the method in question, as determined by the technology itself, should not be unduly limited by the presence of step numbers.
FIG. 1 is a flow chart of one embodiment of a cursor positioning method of the present invention, which includes the following steps.
Step S100, receiving a positioning signal: and the positioning equipment of the cursor receives the positioning signal transmitted by the positioning signal transmitting device through the positioning signal receiving module.
The cursor positioning device may be a screen-equipped device such as a television and a projector. In this embodiment, at least two frames of the screen of the cursor positioning device are provided with the positioning signal receiving modules, and the two frames may be adjacent frames or non-adjacent frames. It can be understood that when two borders in the screen are adjacent, the two borders are perpendicular to each other; when two borders are not adjacent, the two borders are parallel to each other. The positioning signal receiving module is used for receiving the positioning signal transmitted by the positioning signal transmitting device. The positioning device of the cursor is matched with a positioning signal transmitting device, the positioning signal transmitting device is held in the hand of a user, and the user can transmit a positioning signal through a transmitting key in the positioning signal transmitting device.
Furthermore, a screen of the cursor positioning device may also be simultaneously provided with a positioning signal transmitting module and a positioning signal receiving module, for example, two of the frames of the screen are provided with the positioning signal transmitting module, and the other two frames are provided with the positioning signal receiving module; or a positioning signal transmitting module is arranged in one frame of the screen, and positioning signal receiving modules are arranged in the other three frames. At the moment, in order to realize the remote non-contact cursor positioning, a signal receiving element of a positioning signal is arranged in a positioning signal transmitting module of a screen frame of the cursor positioning equipment, so that the cursor positioning equipment has a positioning signal receiving function and receives a positioning signal transmitted by a positioning signal transmitting device. Specifically, the positioning signal may be an infrared signal, and at this time, the positioning signal transmitting module is an infrared transmitting module, and the positioning signal receiving module is an infrared receiving module; the positioning signal can also be a visible light positioning signal, a signal receiving element in the positioning signal receiving module can be an optical sensor at the moment, the positioning signal transmitting module is used for transmitting visible light, and it can be understood that a large amount of visible light exists in the daytime, and the cursor positioning is carried out in a long-distance non-contact mode through the visible light positioning signal at the moment, so that a large amount of interference exists, and the accuracy of the long-distance non-contact cursor positioning is reduced; the positioning signal may also be an ultraviolet signal or an ultrasonic signal, etc. It can be seen that the positioning signal may be an optical signal or an ultrasonic signal, and the optical signal includes an infrared signal, an ultraviolet signal, a visible light signal, and the like.
Step S200, determining intersection point coordinates and calculating positioning coordinates: and determining a first intersection point coordinate of the positioning signal and the screen frame in a coordinate system corresponding to the screen, and calculating the positioning coordinate for positioning the cursor according to the first intersection point coordinate.
After the positioning device of the cursor receives the positioning signal, the positioning device of the cursor determines the intersection point coordinate and calculates the positioning coordinate. Specifically, a coordinate system is set in the screen of the positioning device of the cursor, and specifically, the setting mode of the coordinate system may be set according to specific needs, for example, the lower left corner of the screen may be used as the origin of the coordinate system to establish the coordinate system. After the positioning device of the cursor receives the positioning signal through the positioning signal receiving module, the positioning device of the cursor determines the coordinates of the intersection point of the positioning signal and the screen frame in the coordinate system corresponding to the screen. It is understood that the coordinates of the first intersection point are the coordinates of the positioning signal received by the positioning signal receiving module. And after the positioning equipment of the cursor determines the first intersection point coordinate, the positioning equipment of the cursor calculates the positioning coordinate of the positioning cursor according to the first intersection point coordinate.
Specifically, a positioning signal control board is arranged in the cursor positioning device, and the positioning signal control board is used for scanning the positioning signal receiving module, judging whether the positioning signal receiving module receives the positioning signal, and determining a positioning coordinate corresponding to the positioning signal if the positioning signal is received. It should be noted that, because the positioning signal in this embodiment is a cross light spot signal or an annular light spot signal, at least two intersection points where the positioning signal intersects with the screen frame, that is, at least two coordinates of the first intersection point, are provided. When positioning signal receiving modules in two frames of a screen receive positioning signals, two first intersection point coordinates exist; when the positioning signal receiving modules in the three frames of the screen receive the positioning signals, three first intersection point coordinates exist, namely the number of the first intersection point coordinates is equal to the number of the frames where the positioning signal receiving modules receiving the positioning signals are located.
Further, when the four frames of the screen are provided with positioning signal receiving modules and the positioning signals are cross light spot signals, the step S200 includes:
step a, determining an intersection point of the cross light spot signal and each frame of the screen in a coordinate system corresponding to the screen, and determining the coordinate of the intersection point as a first intersection point coordinate.
And b, determining a first straight line and a second straight line with intersection points according to the first intersection point coordinate, calculating a second intersection point coordinate of the intersection points of the first straight line and the second straight line according to the first intersection point coordinate, and determining the second intersection point coordinate as a positioning coordinate for positioning the cursor.
When the four frames of the screen of the cursor positioning device are provided with the positioning signal receiving modules and the positioning signals are cross light spot signals, the cursor positioning device determines intersection points of the cross light spot signals and the frames of the screen in a coordinate system corresponding to the screen, determines intersection point coordinates of the intersection points, and records the intersection point coordinates as first intersection point coordinates. It should be noted that the cross-shaped light spot signal intersects with four frames of the screen, so there are four intersection points, that is, there are four first intersection coordinates. Specifically, referring to fig. 2, fig. 2 is a schematic diagram of a cross-shaped light spot signal. It can be understood that, when the positioning signal is a cross light spot signal, no matter how the user holds the positioning signal emitting device, as long as the positioning signal emitting device faces the screen of the positioning device of the cursor, the cross light spot signal emitted by the positioning signal emitting device intersects with four borders of the screen. The present embodiment does not limit the angle formed when the cross spot signal intersects the frame of the screen.
After the positioning device of the cursor determines the coordinates of the first intersection point, the positioning device of the cursor determines a first straight line and a second straight line according to the coordinates of the first intersection point, specifically, the positioning device of the cursor connects two non-adjacent coordinates of the first intersection point into a straight line to obtain the first straight line and the second straight line, then a first straight line equation is obtained by calculation according to the coordinates of the first intersection point corresponding to the first straight line, and a second straight line equation is obtained by calculation according to the coordinates of the first intersection point corresponding to the second straight line.
Specifically, referring to fig. 3, the coordinates of the first intersection point are A, B, C and D, the positioning device of the cursor connects non-adjacent a and B into a straight line to obtain a first straight line AB, connects non-adjacent C and D into a straight line to obtain a second straight line CD, and then calculates a first straight line equation of the first straight line according to the coordinates of the first intersection point of a (x1, y1) and the coordinates of the first intersection point of B (x2, y2), the first straight line equation being formula (1); and calculating a second line equation of a second line according to the first intersection point coordinate (x3, y3) of the C and the first intersection point coordinate (x4, y4) of the D, wherein the second line equation is formula (2). After the positioning device of the cursor obtains the first linear equation and the second linear equation, the first linear equation and the second linear equation are solved through geometric operation to obtain solutions corresponding to the first linear equation and the second linear equation, where the solutions corresponding to the first linear equation and the second linear equation are coordinates of intersection points of the first straight line and the second straight line. And after the positioning equipment of the cursor obtains the second intersection point coordinate, the positioning equipment of the cursor determines the second intersection point coordinate as the positioning coordinate of the positioning cursor signal.
Formula (1):
formula (2):
formula (3):
formula (4):
wherein, the formula (3) is an expression of the abscissa of the corresponding solution of the first linear equation and the second linear equation; the formula (4) is an expression of the ordinate of the solution corresponding to the first linear equation and the second linear equation, and when the ordinate of the coordinate of the intersection corresponding to the first linear equation and the second linear equation is calculated, x in the formula (3) needs to be substituted into the formula (4).
Further, when the four frames of the screen are provided with positioning signal receiving modules and the positioning signals are annular light spot signals, the step S200 further includes:
and e, determining an intersection point of the annular light spot signal and the screen frame in a coordinate system corresponding to the screen, and determining the coordinate of the intersection point as a first intersection point coordinate.
And f, determining a first intersection point coordinate belonging to the same signal circle in the screen frame, and determining a first perpendicular bisector and a second perpendicular bisector according to the first intersection point coordinate, wherein the diameters of the signal circles corresponding to the first perpendicular bisector and the second perpendicular bisector are different.
And g, calculating a third intersection point coordinate of the intersection point of the first perpendicular bisector and the second perpendicular bisector according to the first intersection point coordinate, and determining the third intersection point coordinate as a positioning coordinate for positioning the cursor.
When the four frames of the screen of the cursor positioning device are provided with the positioning signal receiving modules and the positioning signals are annular light spot signals, the cursor positioning device determines intersection points of the annular light spot signals and the screen frames in a coordinate system corresponding to the screen, and determines intersection point coordinates of the annular light spot signals and the screen frames as first intersection point coordinates. It should be noted that, when the positioning signal transmitting device transmits an annular light spot signal, the annular light spot signal may form a plurality of concentric circles with different diameters in the screen, that is, a plurality of signal circles with different diameters, at this time, the positioning device of the cursor selects two signal circles intersecting with the screen frame, and determines a first intersection point coordinate belonging to the same signal circle in the adjacent frame of the screen. It should be noted that the signal rings with different diameters are arranged to adapt to the situation that the distance between the positioning signal emitting device and the screen is different, and the signal rings can intersect with the screen frame. Specifically, referring to fig. 4, a1(X1, Y1) and A3(X3, Y3) are first intersection coordinates belonging to the same signal circle in the screen frame, and B2(X2, Y2) and B4(X4, Y4) are first intersection coordinates belonging to the same signal circle in the screen frame.
And after the positioning equipment of the cursor determines a first intersection point coordinate belonging to the same signal circle in the screen frame, determining a first perpendicular bisector and a second perpendicular bisector according to the first intersection point coordinate. Specifically, the positioning device of the cursor connects points corresponding to first intersection coordinates belonging to the same signal circle to obtain a fifth straight line and a sixth straight line, a perpendicular bisector corresponding to the fifth straight line is recorded as a first perpendicular bisector, a perpendicular bisector corresponding to the sixth straight line is recorded as a second perpendicular bisector, then a midpoint coordinate corresponding to the first intersection coordinates belonging to the same signal circle and a slope of the perpendicular bisector of the fifth straight line are calculated, a perpendicular bisector equation corresponding to the signal circle is obtained according to the slope of the perpendicular bisector and the slope of the perpendicular bisector, and the equation of the first perpendicular bisector is recorded as the first perpendicular bisector equation in this embodiment. With continued reference to FIG. 4, the fifth straight line is A1A3, the abscissa of the corresponding midpoint coordinate is the average of the A1 abscissa and the A3 abscissa, and the ordinate of the corresponding midpoint coordinate is the average of the A1 ordinate and the A3 ordinate. It should be noted that the calculation process of the second perpendicular bisector equation is the same as the calculation process of the first perpendicular bisector equation, and details are not repeated here. It will be appreciated that the first and second plumb line equations correspond to different diameters of the signal circle, i.e., the first and second plumb lines correspond to different diameters of the signal circle.
After the positioning device of the cursor obtains the first perpendicular bisector equation and the second perpendicular bisector equation, the positioning device of the cursor calculates solutions corresponding to the first perpendicular bisector equation and the second perpendicular bisector equation through geometric operation, where the solutions of the first perpendicular bisector equation and the second perpendicular bisector equation are coordinates of an intersection point of the first perpendicular bisector and the second perpendicular bisector, in this embodiment, coordinates of the intersection point of the first perpendicular bisector and the second perpendicular bisector are recorded as coordinates of a third intersection point, that is, the positioning device of the cursor calculates coordinates of the third intersection point of the first perpendicular bisector and the second perpendicular bisector according to the coordinates of the first intersection point, and determines the coordinates of the third intersection point as positioning coordinates for positioning the cursor. Specifically, the first perpendicular bisector equation is formula (5), the second perpendicular bisector equation is formula (6), the abscissa expression of the solution corresponding to the first perpendicular bisector equation and the second perpendicular bisector equation is formula (7), and the ordinate expression of the solution corresponding to the first perpendicular bisector equation and the second perpendicular bisector equation is formula (8).
Formula (5):
formula (6):
formula (7):
formula (8):
it is understood that in calculating "y" in formula (8), "x" calculated by formula (7) needs to be substituted into formula (8).
Step S300, moving a cursor: and controlling the cursor in the screen to move from the current position to the position of the positioning coordinate.
After the positioning device of the cursor determines the positioning coordinates, the positioning device of the cursor determines the current position of the screen cursor, and then controls the cursor in the screen to move from the current position to the position of the positioning coordinates, so that the position of the cursor is determined, and the cursor positioning function is realized.
In this embodiment, a positioning signal receiving module is arranged in at least two frames of a screen of a cursor positioning device, the positioning signal receiving module receives a positioning signal, a first intersection point coordinate where the positioning signal intersects with the frame of the screen is determined in a coordinate system corresponding to the screen, a positioning coordinate where the cursor is positioned is calculated according to the first intersection point coordinate, and the cursor in the screen is controlled to move from a current position to a position where the positioning coordinate is located. The position of the cursor is positioned through the intersection point of the positioning signal and the screen frame, a user only needs to hold the positioning signal transmitting device to transmit the positioning signal without contacting the screen of the positioning equipment of the cursor, and the cursor in the screen of the positioning equipment for remotely positioning the cursor is positioned.
Further, the positioning method of the cursor further comprises the following steps:
and h, when the response signal is detected, executing response operation according to the current working mode of the positioning equipment of the cursor so as to control the positioning equipment of the cursor.
When the positioning device of the cursor detects the response signal, the positioning device of the cursor determines the current working mode of the positioning device of the cursor, and executes corresponding response operation according to the current working mode to control the positioning device of the cursor. The response signal may be automatically triggered by the positioning device of the cursor, for example, after the cursor moves to the position of the positioning coordinate in the screen, if the positioning device of the cursor detects that the time length of the cursor staying at the position is longer than the preset time length, the positioning device of the cursor triggers the response signal, and the embodiment does not limit the size of the preset time length. The response signal may also be sent to the positioning device of the cursor by the user through the positioning signal transmitting device, and at this time, at least one key for triggering the response signal is provided in the positioning signal transmitting device, and the user may trigger the response signal through the key. It will be appreciated that when there are multiple keys in the positioning signal emitting device, the function performed by each key is not the same. The operational modes include, but are not limited to, a drawing mode, a writing mode, and a browsing mode. If the current working mode of the positioning device of the cursor is the browsing mode, if the positioning device of the cursor detects a response signal, the positioning device of the cursor can perform page turning operation through the response signal, and if a corresponding sub-link exists at the current position of the cursor, a display page can click the sub-link through the response signal to enter the corresponding sub-page, thereby realizing remote control of the positioning device of the contactless control cursor.
Furthermore, another embodiment of the positioning method of the cursor of the present invention is provided.
The difference between the other embodiment of the cursor positioning method and the embodiment of the cursor positioning method is that when two borders of the screen are provided with positioning signal receiving modules and the positioning signals are cross light spot signals, the step S200 includes:
and i, determining an intersection point of two continuous cross light spot signals and a frame of the screen provided with a positioning signal receiving module, and determining the coordinate of the intersection point as a first intersection point coordinate.
In this embodiment, when the positioning signal receiving module is disposed in two frames of a screen of the cursor positioning device, at this time, the frame on which the positioning signal receiving module is disposed may be two parallel frames or two perpendicular frames. When the positioning signal is a cross light spot signal, the positioning equipment of the cursor acquires two continuous cross light spot signals, determines the intersection point of the two continuous cross light spot signals and each frame of the screen, and determines the coordinate of the intersection point as the coordinate of the first intersection point. It should be noted that, when only two frames in the screen of the cursor positioning device are provided with the positioning signal receiving modules, if only one cross light spot signal is obtained, only two first intersection coordinates can be obtained, at this time, two straight lines cannot be formed, and two straight line equations are obtained, so that an intersection point where two continuous cross light spot signals intersect with the frame in the screen provided with the positioning signal receiving modules is obtained within a certain time period, four first intersection coordinates can be obtained, two straight lines are formed, and two straight line equations are obtained. To ensure cursor positioning accuracy, the time to acquire the two cross spot signals should be as short as possible. Specifically, the user can hold the positioning signal transmitting device by hand, and continuously transmit the positioning signal to the positioning signal receiving module twice, or set the positioning signal transmitting device, after the positioning signal transmitting device transmits the positioning signal to the positioning device of the cursor for the first time, the transmitter in the positioning signal transmitting device rotates by a certain angle, and continues to transmit the positioning signal to the positioning device of the cursor for the second time, at this time, for the user, the user only needs to trigger the positioning signal transmitting button once, but the positioning signal transmitting device can transmit the positioning signal to the positioning device of the cursor twice.
Step j, determining a straight line corresponding to the first intersection point coordinate of each cross light spot signal to obtain a third straight line and a fourth straight line, wherein one cross light spot signal corresponds to one straight line;
and k, calculating fourth intersection point coordinates of intersection points of the third straight line and the fourth straight line according to the first intersection point coordinates, and determining the fourth intersection point coordinates as positioning coordinates for positioning the cursor.
After the positioning device of the cursor determines the coordinates of the first intersection point, the positioning device of the cursor determines a straight line corresponding to the coordinates of the first intersection point of each cross light spot signal, so as to obtain a third straight line and a fourth straight line, wherein one cross light spot signal corresponds to one straight line. If the coordinates of the first intersection point formed by the first cross spot signal in the screen are E and F, the third straight line is the straight line EF. And after the positioning equipment of the cursor obtains the third straight line and the fourth straight line, the positioning equipment of the cursor calculates the fourth intersection point coordinate of the intersection point of the third straight line and the fourth straight line according to the first intersection point coordinate, and determines the fourth intersection point coordinate as the positioning coordinate of the positioning cursor. It should be noted that, the implementation process of step k is the same as the process of "calculating the second intersection point coordinate of the intersection point of the first straight line and the second straight line according to the first intersection point coordinate, and determining the second intersection point coordinate as the positioning coordinate for positioning the cursor" in step b, and details are not repeated here.
In this embodiment, when only two frames of the screen of the positioning device of the cursor are provided with the positioning signal receiving modules, the cursor is positioned by acquiring the positioning signals twice continuously, and the remote cursor positioning is realized under the condition of reducing the production cost of the positioning device of the cursor (without arranging the positioning signal receiving modules on all the four frames of the screen of the positioning device of the cursor).
Further, the positioning signal receiving module is an infrared signal receiving module, and the infrared signal receiving module is composed of an LED (Light Emitting Diode) array, that is, the LED is used for receiving an infrared signal, and at this time, the LED is specifically a receiving Diode or a photosensitive pair transistor. In step S200, the step of determining the first intersection coordinate of the positioning signal received by the positioning signal receiving module in the coordinate system corresponding to the screen includes:
and step l, judging the number of LEDs with level changes in the infrared signal receiving module corresponding to the same frame of the screen.
In this embodiment, the positioning signal receiving module in the screen frame of the cursor positioning device is an infrared signal receiving module, and the infrared signal receiving module may be composed of an LED array, at this time, the positioning signal emitting device emits infrared rays with a specific wavelength, and generates an invisible cross light spot signal or an annular light spot signal in the screen. Specifically, referring to fig. 5, in fig. 5, LED arrays are disposed in all four borders of the display screen. When the positioning device of the cursor receives an infrared signal through the infrared signal receiving module, and the infrared signal is the positioning signal, the positioning device of the cursor judges the number of LEDs with level change in the infrared signal receiving module corresponding to the same frame of the screen. It should be noted that when the infrared signal receiving module receives an infrared signal, there is a level change in the LED receiving the infrared signal, and specifically, whether the LED changes from a high level to a low level or from a low level to a high level may be set according to specific needs.
And m, if the number of LEDs with level change in the same frame of the screen is at least two, determining the LED with the maximum level change amplitude, and determining the coordinate corresponding to the LED with the maximum level change amplitude in the coordinate system corresponding to the screen as the first intersection point coordinate of the intersection of the positioning signal and the frame of the screen.
And n, if the number of LEDs with level changes in the same frame of the screen is one, determining the corresponding coordinates of the LEDs with the level changes as the coordinates of a first intersection point where the positioning signals are intersected with the frame of the screen in a coordinate system corresponding to the screen.
If the positioning equipment of the cursor determines that the number of LEDs with level change in the same frame of the screen is at least two, the positioning equipment of the cursor determines the LED with the maximum level change amplitude, then determines the coordinate of the LED with the maximum level change amplitude in a coordinate system corresponding to the screen, and determines the coordinate corresponding to the LED with the maximum level change amplitude as a first intersection point coordinate of the intersection of the positioning signal and the frame of the screen; if the number of the LEDs with level changes in the same frame of the screen is one, determining the corresponding coordinates of the LEDs with level changes in the corresponding coordinate system of the screen as the coordinates of a first intersection point where the positioning signals are intersected with the frame of the screen. It can be understood that the determination process for determining the coordinates of the first intersection point corresponding to each frame in the screen is the same, and the detailed description is not repeated here.
And step o, if the number of the LEDs with level changes in the same frame of the screen is at least two, and the change amplitudes of the LEDs with level changes are smaller than a first preset amplitude, determining a target LED with the level change amplitude larger than a second preset amplitude, and determining a median of coordinates corresponding to the target LED in a coordinate system corresponding to the screen as a first intersection coordinate of the positioning signal and the frame of the screen, wherein the second preset amplitude is smaller than the first preset amplitude.
Further, if the number of LEDs with level changes in the same frame of the screen is at least two, the positioning device of the cursor calculates the change amplitude of each LED with level changes, and determines whether the change amplitude of each LED is smaller than a first preset amplitude, where the first preset amplitude may be set according to specific needs, and the embodiment does not limit the size of the first preset amplitude. If the change amplitude of the LED with the changed level is smaller than the first preset amplitude, the positioning device of the cursor determines a target LED with the changed level amplitude larger than the second preset amplitude, and determines the median of the corresponding coordinate of the target LED in a coordinate system corresponding to the screen as the first intersection point coordinate of the intersection of the positioning signal and the screen frame, wherein the second preset amplitude is smaller than the first preset amplitude. Further, the target LED may be limited to adjacent LEDs.
If the number of LEDs with level changes in the same frame of the screen is 5, the level change amplitude of the 5 LEDs is smaller than a first preset amplitude, but the level change amplitude of the 3 LEDs is larger than a second preset amplitude, the 3 LEDs with the level change amplitudes larger than the second preset amplitude are determined as target LEDs, at this time, the first intersection point coordinate is the coordinate of the LED in the middle of the 3 target LEDs, and if the LED in the middle is (A)0，B0) Then the first intersection coordinate is (A)0，B0) (ii) a If the level change amplitude of 4 LEDs is larger than the second preset amplitude, determining 4 LEDs with the level change amplitude larger than the second preset amplitude as target LEDs, wherein the first intersection point coordinate is the average value of the coordinates of the two LEDs in the middle of the 4 target LEDs, for example, the coordinate of the two LEDs in the middle is (A)1，B1) And (A)2，B2) Then the first intersection coordinate is ((A)1+A2)÷2，(B1+B2) 2). It can be understood that when the number of the target LEDs is an even number, the target LEDs are arranged according to the sequence of the target LED positions, such as from left to right, or from top to bottom, and the first intersection coordinate is the average value of the coordinates of the two target LEDs arranged in the middle; when the number of target LEDs is an odd number, the first intersection coordinates are the coordinates of the target LED arranged in the middle.
Further, if the positioning device of the cursor determines that the variation amplitude of the LED is larger than the first preset amplitude, the positioning device of the cursor determines the LED with the largest level variation amplitude, and the corresponding coordinate of the LED with the largest level variation amplitude in the coordinate system corresponding to the screen is determined as the first intersection point coordinate where the positioning signal intersects with the screen frame.
Or the positioning device of the cursor can also determine the middle position of each LED with level variation in the frame, and determine the coordinate corresponding to the middle position as the first intersection point coordinate of the positioning signal intersecting with the frame of the screen, for example, when there are 6 LEDs with level variation in the frame, the first intersection point coordinate is the average value of the coordinates of the LEDs located at the 3 rd and 4 th positions in the 6 LEDs, if there are any, the position of each LED is changed by the positioning device of the cursorThe LED coordinate at position 3 is (A)3，B3) And the LED coordinate at the 4 th position is (A)4，B4) Then the middle position corresponds to the coordinate ((A)3+A4)÷2，(B3+B4) 2), i.e. the first intersection coordinate is ((a)3+A4)÷2，(B3+B4) 2); when there are 7 LEDs with level changes in the frame, the first intersection coordinate is the 4 th LED coordinate. It can be understood that, at this time, when the number of LEDs having a level change is an even number, the coordinate corresponding to the middle position is an average value of the coordinates of the two LEDs located in the middle; when the number of LEDs in which there is a level change is odd, the coordinate corresponding to the middle position is the coordinate of the LED located in the middle.
If there are 6 LEDs with level changes in the frame, the first intersection coordinate is the average of the 3 rd and 4 th LED coordinates of the 6 LEDs, and if the 3 rd LED coordinate is (a)3，B3) And the LED coordinate at the 4 th position is (A)4，B4) Then the middle position corresponds to the coordinate ((A)3+A4)÷2，(B3+B4) 2), i.e. the first intersection coordinate is ((a)3+A4)÷2，(B3+B4) 2); when there are 7 LEDs with level changes in the frame, the first intersection coordinate is the 4 th LED coordinate. It can be understood that, at this time, when the number of LEDs having a level change is an even number, the coordinate corresponding to the middle position is an average value of the coordinates of the two LEDs located in the middle; when the number of LEDs in which there is a level change is odd, the coordinate corresponding to the middle position is the coordinate of the LED located in the middle.
In the embodiment, when a plurality of LEDs with level changes exist in the same frame of the screen of the cursor positioning device, the corresponding coordinate of the LED with the largest level change amplitude is determined as the coordinate of the first intersection point where the positioning signal intersects the frame of the screen, or the corresponding coordinate of the middle position of each LED with level changes in the frame is determined as the coordinate of the first intersection point where the positioning signal intersects the frame of the screen, so that the accuracy of determining the coordinate of the first intersection point is improved, that is, the accuracy of positioning the cursor in the screen of the cursor positioning device is improved.
