The embodiment of the invention provides a touch calibration method based on a display screen, and referring to fig. 2, fig. 2 is a flow chart of a first embodiment of the touch calibration method based on the display screen.
In this embodiment, the touch calibration method based on the display screen includes the following steps:
step S10: and when entering a touch calibration mode, acquiring touch coordinates of the current response of the display screen.
It should be noted that, the execution body of the embodiment is a touch calibration device based on a display screen, where the touch calibration device based on the display screen has functions of data processing, data communication, program running, etc., and the touch calibration device based on the display screen may be an integrated controller, a control computer, etc., or may be other devices with similar functions, which is not limited in this embodiment.
It can be understood that the touch calibration mode is one of the operation modes of the display screen, and in this embodiment, the touch calibration mode can exist simultaneously in the operation state, that is, the operation is performed while the calibration is performed, and the touch coordinates refer to the touch event detected on the display screen, and the touch coordinates currently responded on the display screen are determined according to the touch event.
In a specific implementation, when the display screen works normally, whether the touch calibration mode is started or not can be selected, when the touch calibration mode is started, touch calibration can be performed simultaneously when the display screen works, and the use complexity of a user for using the display screen can be simplified. When the touch calibration mode is started, when a user performs touch operation on the display screen, the display screen can be monitored, and when a response event is triggered on the display screen, a touch signal is triggered, so that the touch coordinate of the current response is obtained. The present embodiment is described with reference to a display screen of a mobile phone. When the mobile phone starts a touch calibration mode, touch coordinates of the response of the display screen can be monitored, water drops possibly fall down on the display screen of the mobile phone or touch failure or touch misalignment is caused by water on fingers when the mobile phone is operated according to the use habit of the mobile phone, and under normal conditions, the water drops on the display screen and the fingers of a user are regarded as the touch coordinates, so that an internal program can be trapped to continuously execute response events corresponding to the touch coordinates when the touch coordinates are processed, and further, the situation that the picture becomes jittery or other influences on use occur. Therefore, when the touch calibration mode is entered, the touch coordinate of the current response of the display screen is obtained.
Step S20: and acquiring a display picture of the display screen, and determining a target response control of the current interface according to the display picture.
It should be noted that, the display screen of the display screen refers to the display content of the current display screen, which includes the image information displayed in the display screen and the response controls available for interaction in the display screen, and the target response control refers to the selected response control of the current response controls in the display screen.
In a specific implementation, a current display picture of a display screen is monitored and identified, the positions of response controls in the display picture are obtained, the positions of the response controls which can be corresponding to the touch coordinates are determined by comparing the obtained touch coordinates with the response areas of the response controls, and corresponding target response controls are determined, wherein the target response controls can be in any number. In the process, the respondable controls in the current display picture can be numbered, and the response information of each respondable control can be determined, wherein the response information comprises the response range, the response mode and the like.
Step S30: determining a response area of the target response control, determining a touch vector according to the response area of the target response control and the touch coordinate, determining a touch priority of the touch coordinate according to the touch vector, and determining a touch response queue according to the touch priority.
It should be noted that, the response area refers to a range in which the target response control can identify the touch coordinate, and when the response area of the target response control includes the touch coordinate or the touch range corresponding to the touch coordinate, it can be determined that the target response control of the current touch event includes the current target controllable area. The touch priority refers to that when a plurality of touch coordinates are included in the response area, each touch coordinate can be selected and ordered to obtain the touch priority, and the touch response queue is a data set obtained by ordering the touch coordinates according to the touch priority.
In a specific implementation, a response area of a target response control is determined, a display screen coordinate system is established by taking a display screen as a reference, the display screen coordinate system is a plane rectangular coordinate system, a display picture can be projected to the display screen coordinate system, the response area of each target response control can be determined, for each response control, a touch center exists, the touch center is the middle of the response area, a touch vector is determined according to the touch coordinates, the touch vector comprises a distance between two coordinate points, the distance between the two coordinate points can also be called as a mode of the touch vector, and the direction of a connecting line between the two coordinate points is also included. Because the touch coordinates and the coordinates of the touch center of the target response area are in the same plane in the space where the display screen is located, the touch vectors of two touch points can be determined, the touch vectors are further analyzed, the priority of the touch vectors is obtained, and then a touch response queue is determined according to the touch priority.
Further, the determining the response area of the target response control, determining a touch vector according to the target response control and the touch coordinate, determining a touch priority of the touch coordinate according to the touch vector, and determining a touch response queue according to the touch priority, includes:
Determining a response area of the target response control, and acquiring response center coordinates of the response area according to the response area;
taking the touch coordinate as a starting point and the response center coordinate as an end point to obtain a touch direction between the target response control and the touch coordinate;
Determining a touch distance according to the touch center coordinates and the touch coordinates;
obtaining the touch vector according to the touch direction and the touch distance;
And sequencing the modes of the touch vectors, determining the touch priority of each touch coordinate, and determining a touch response queue according to the touch priority.
In a specific implementation, referring to fig. 3, fig. 3 is a position relationship diagram of touch coordinates and a response area in a coordinate system. Therefore, if the touch coordinate isThe coordinates of the touch center are/>Then the touch vector may be represented asThen the distance between the two coordinate points is denoted/>。
When determining the priority of the vector, the distance between the touch coordinate and the coordinate of the touch center of the target response area is preferentially determinedAnd comparing, namely sorting the touch response queues according to the distances from small to large, and if the distances between two coordinate points corresponding to two or more touch vectors are equal, determining the priority according to the preset direction selection, wherein the priority can be determined by taking the vertical axis as the initial direction and clockwise as the positive direction, and determining the touch response queue according to the touch response priority.
Step S40: and screening the touch response queue to obtain an effective touch response queue, and obtaining target touch coordinates according to the effective touch response queue.
It should be noted that, the target touch coordinates refer to touch coordinates capable of triggering the response control to execute related operations, and the number of the target touch coordinates is associated with a triggering event to be executed according to needs.
In a specific implementation, the touch coordinates in the touch response queue refer to the generated touch coordinates identified by the display screen. However, there may be a factor of non-user behavior, such as water, to generate the touch coordinates on the display screen, but it is obvious that the touch coordinates generated by water or the like are not wanted, so that the touch response queue needs to be screened to obtain an effective touch response queue, and then the target touch coordinates are obtained for the effective touch response queue.
Further, the screening the touch response queue to obtain an effective touch response queue, and obtaining the target touch coordinate according to the effective touch response queue, further includes:
acquiring a capacitance signal of the display screen, and converting the capacitance signal into a digital signal;
Determining touch coordinates according to the digital signals, and monitoring the motion trail of the touch coordinates and the touch time for maintaining the motion trail;
And outputting the touch coordinate as an effective touch coordinate when the motion track meets a preset motion track and the touch time is smaller than the preset touch time, adding the effective touch coordinate to the effective touch response queue, and obtaining a target touch coordinate according to the effective touch response queue.
When the user performs a touch operation, the display screen generates a capacitance signal, at this time, the touch position can be determined according to the capacitance signal, but in this embodiment, the capacitance signal is converted into a digital signal, the digital signal is analyzed, the touch position is determined, at this time, the obtained position only indicates that the touch operation exists in the current position, but the touch behavior cannot be accurately identified, for example, the touch behavior of the user is not the touch behavior but drops on the display screen, at this time, the display screen still generates the capacitance signal, and the touch coordinate is identified, when the touch coordinate is in the response area, the false touch behavior is caused, namely, the non-subjectively expected touch behavior is generated, so that the touch coordinate in the display screen needs to be analyzed, whether the touch coordinate is the operation performed by the user is determined, and the false touch behavior caused by similar water drops is eliminated. Therefore, when the touch coordinate is detected, the motion track of the touch coordinate and the touch time consumed for maintaining the motion track can be monitored, for example, when the touch coordinate is not changed for a long time, the current operation can be determined not to be the user operation at the moment when the motion track is not moved, so that when the operation is executed, the touch behavior corresponding to the current touch coordinate needs to be shielded, and in one case: when a drop of water falls in a corresponding response area in the display screen, the user operates the mobile phone under the condition of wetting hands, and simultaneously, the user executes related touch operation, at the moment, the display screen receives two touch signals, one touch signal can be recognized for a long time and does not change for a long time, at the moment, the current touch coordinate can be defined as an invalid touch coordinate, the other touch coordinate in the change is an effective coordinate, and the touch coordinate can be determined to be executed by the user. In another case, the water drops flow on the display screen, the positions of touch coordinates triggered by the water drops are continuously changed, and one point can be determined, so that the touch coordinates generated by the display screen can be tracked and monitored at the moment in the flowing process of the water drops, if continuous long-time movement of the touch coordinates occurs to a certain touch coordinate, the current touch coordinates can be regarded as invalid coordinates, the coordinates can be continuously monitored, and in the subsequent processing, the touch time of the coordinates can be adjusted to be free of operation, and at the moment, the touch coordinates generated by non-user behaviors caused by factors such as the water drops can be eliminated, so that the influence of external environments on the touch behaviors can be eliminated from the source, and the touch behaviors of users can be greatly optimized. After the invalid touch coordinates are eliminated, the rest touch coordinates can be added into a touch response queue in the form of valid coordinates, and then the coordinates in the touch response queue are screened to obtain target control coordinates.
Further, the screening the touch response queue to obtain an effective touch response queue, and obtaining the target touch coordinate according to the effective touch response queue includes:
Acquiring an under-screen image of the display screen, wherein the under-screen image comprises a touch image of a touch position;
Determining a touch image according to the touch coordinates and the under-screen image;
Detecting the brightness of the touch image to obtain brightness information of the touch image;
Determining a brightness value of the brightness information, and outputting a touch image corresponding to the brightness value as an effective touch image when the brightness value is smaller than a preset brightness value;
And determining the touch coordinates according to the effective touch image, adding the touch coordinates to the effective touch response queue according to the touch coordinates, and obtaining target touch coordinates according to the effective touch response queue.
In a specific implementation, the image information of the touch position above the display screen, which is also called an under-screen image, can be obtained through the under-screen sensor, and because the touch operation performed by the user is performed by using a finger or by using a touch device such as a touch pen to perform touch actions, shielding of a certain area occurs in a touch area, interference caused by substances such as water and the like is caused, and the under-screen image of the obtained display screen can be obtained according to the physical characteristics of the under-screen image. At this time, brightness detection can be performed on the touch images, brightness information of each touch image is determined, a brightness value of each image is obtained, when the brightness value is smaller than a preset brightness value, the touch image corresponding to the brightness value is output as an effective touch image, and the preset brightness value is obtained according to big data analysis. The effective touch coordinates can be determined according to the effective touch images, because the touch images are acquired from the under-screen images corresponding to the touch coordinates. After the effective touch coordinates are obtained, the effective touch coordinates can be added to an effective touch coordinate queue, and the target touch coordinates are further obtained.
Step S50: and determining a touch calibration quantity according to the target touch coordinate and the response area, and performing touch calibration according to the touch calibration quantity.
It should be noted that, the touch calibration amount refers to a physical amount corresponding to a touch center and a positional relationship between a touch range and a response control in order to solve a current target touch coordinate when performing a touch operation.
In a specific implementation, when determining a touch calibration amount according to a target touch coordinate and a response area, determining a position relationship between the touch coordinate and the response area, and when the target touch coordinate is located in the response area, calibrating is not required; when the target touch coordinate is located outside the response area, the touch range at the moment is necessarily coincident with the response area, in this case, the shortest distance from the touch coordinate to the response area can be used as a calibration length, the direction in which the touch center is located is used as a calibration direction, the touch calibration quantity is obtained according to the calibration length and the calibration direction, and the touch calibration is performed according to the touch calibration quantity. When touch calibration is performed according to the touch calibration amount, coordinate values of the touch coordinates can be directly changed into new coordinate values based on the touch calibration amount on the basis of the touch coordinates during coordinate processing, and the calibrated touch coordinates are obtained.
According to the method, when a touch calibration mode is entered, touch coordinates of a current response of a display screen are obtained, a display picture of the display screen is obtained, a target response control of the current interface is determined according to the display picture, a response area of the target response control is determined, a touch vector is determined according to the response area of the target response control and the touch coordinates, a touch priority of the touch coordinates is determined according to the touch vector, a touch response queue is determined according to the touch priority, the touch response queue is screened, an effective touch response queue is obtained, target touch coordinates are obtained according to the effective touch response queue, a touch calibration amount is determined according to the target touch coordinates and the response area, touch calibration is performed according to the touch calibration amount, and accurate calibration of the display screen is achieved.
Referring to fig. 4, fig. 4 is a flowchart illustrating a touch calibration method based on a display screen according to a second embodiment of the present invention.
Based on the first embodiment, the touch calibration method based on a display screen of the present embodiment further includes, before the step S50:
Step S501: and determining a touch trigger range of the target touch coordinate according to the target touch coordinate.
Step S502: and determining the number of the responsive controls in the touch trigger range.
Step S503: and detecting the number of the control parts which can be responded to obtain a detection result.
Step S504: and executing the step of determining the touch calibration quantity according to the target touch coordinates and the response area based on the detection result.
In a specific implementation, before calibration, a touch trigger range of the target touch coordinate needs to be determined according to the target touch coordinate, for example, a contact area of a finger and a display screen, coordinate values covered by the contact area can be regarded as the touch trigger range, that is, when coordinates of a response area of a response control appear in the touch trigger range, at the moment, the two areas overlap, and the current touch action can be regarded as an effective touch action. However, in order to ensure that the touch behavior can be accurately executed, the number of the respondable controls in the touch trigger range needs to be confirmed, the number of the respondable controls is detected to obtain a detection result, the detection result is the number of the respondable controls, and the step of determining the touch calibration amount according to the target touch coordinates and the response area is executed based on the detection result.
Further, the determining a touch calibration amount according to the target touch coordinate and the response area, and performing touch calibration according to the touch calibration amount, further includes:
when the number of the respondable areas is a first preset number, determining the position relation between the target touch coordinates and the response areas;

In fig. 5, two positions correspond to each other, and from the left side in fig. 5, it can be seen that the trigger center of the trigger area is not in the response area, but there is a coincidence area between the two areas, so that the current touch behavior can be considered as being established at this time, and since the touch coordinates are not in the response area, it is necessary to determine the coordinate equation of the response area, calculate the shortest distance, that is, the calibration distance, between the touch coordinates and the response area, and obtain the touch calibration value.
