In this embodiment, the screen touch management method includes:
step S100, when the front camera is not started and an object is detected to be close to the front camera based on the proximity sensor, starting the front camera and determining whether the close object is a finger of a user;
in this embodiment, the full-screen of the current intelligent terminal is a quasi-full-screen, so that a real full-screen mobile phone will appear in the future, and the full-screen mobile phone will be a necessary trend in the future. The technical obstacles such as fingerprint under the screen, screen sound production have been solved at present to comprehensive screen cell-phone, and the technical obstacle that still needs to solve at present is exactly camera under the screen, and two main problems need to be solved to camera under the screen: firstly, displaying a screen at the position of an opening of a camera under the screen; and secondly, touch control of the opening position of the camera under the screen. The technical scheme of the invention solves the second problem: and (5) touch control of the opening position of the camera under the screen.
Specifically, intelligent terminal sets up proximity sensor in camera trompil position for whether detect the object and be close to camera under the screen, so that trigger the start-up of camera under the screen. A proximity sensor is a device capable of sensing the proximity of an object, and recognizes the proximity of the object by using the sensitivity of a displacement sensor to the approaching object and outputs a corresponding switch signal, and thus, the proximity sensor is also generally called a proximity switch. It is a generic name of a sensor for the purpose of not touching an object to be detected, instead of a contact detection type detection method such as a switch, and it can detect movement and presence information of an object and convert it into an electric signal. In addition, the intelligent terminal is also provided with a tracking mode, and the tracking mode is used for capturing the motion trail of the finger of the user according to the video image shot by the camera. When the front camera of the intelligent terminal is not started and the proximity sensor detects that the object is close to the front camera, the front camera is started to shoot an image of the close object, and whether the close object is a finger of the user is determined according to a preset image recognition algorithm. It should be noted that, if the front-facing camera of the intelligent terminal is being used in the use periods of photographing, face recognition, photographing, video call, etc., if the proximity sensor detects that an object is close to the front-facing camera, the touch event at the opening position corresponding to the front-facing camera under the screen is not responded.
Step S200, when the approaching object is determined to be the finger of the user, starting the tracking mode, and acquiring the motion track of the finger of the user based on the front camera and the tracking mode;
in this embodiment, when the proximity sensor detects that an object is close to the front camera, and after it is determined that the object is a user finger according to the front camera of the intelligent terminal and a preset image recognition algorithm, a tracking mode of the intelligent terminal is started, and then a motion track of the user finger is captured according to a video image captured by the camera. A motion trajectory refers to a spatial feature of motion that is composed of the path that a part of the body takes from the starting position to the end. The motion trail is represented by a motion trail direction, a motion trail form and a motion amplitude. In the invention, the motion trail of the finger of the user refers to the spatial characteristics of the motion formed by the paths which the finger passes through from the starting position to the end in the shooting area after the front camera is started, the direction of the motion trail of the finger is changed continuously, and the motion trail is in the form of a curve.
Specifically, the moving target tracking means that a moving target of interest is found in each image in a sequence of images in real time, and the moving target comprises motion parameters such as position, speed and acceleration.
Step S300, acquiring four-dimensional coordinates of the sampling points on the motion trail based on a preset time interval, wherein the four-dimensional coordinates comprise horizontal X-direction coordinates, vertical Y-direction coordinates, far and near Z-direction coordinates and trail time;
in this embodiment, the movement locus of the finger may be represented by a four-dimensional coordinate system, which is an X axis in the horizontal direction, a Y axis in the vertical direction, a Z axis in the near-far direction, and a time T axis, respectively, where an origin of the coordinate system may be set according to an actual situation. The motion trajectory of the finger is a curve and is represented by a four-dimensional coordinate system, so that the motion trajectory can be sampled according to a preset time interval to obtain a plurality of sampling points, each sampling point is represented by a four-dimensional coordinate, the four-dimensional coordinate comprises a horizontal X-direction coordinate, a vertical Y-direction coordinate, a far-near Z-direction coordinate and trajectory time, and the sampling points are used for determining a touch type corresponding to the finger operation, for example, determining that the current finger operation is leftward sliding, downward sliding and the like. The preset time interval is determined according to the actual condition, the number of sampling points is determined by the preset time interval, and at least 2 sampling points are ensured.
Step S400, determining a touch type corresponding to the motion track based on the four-dimensional coordinates of each sampling point and a preset touch template, and executing touch operation based on the touch type.
In this embodiment, after the four-dimensional coordinates of the sampling point on the motion trajectory are acquired according to the preset time interval, the touch type corresponding to the motion trajectory is further determined according to the four-dimensional coordinates of the sampling point and the preset touch template. Wherein the touch type includes: left-sliding touch, right-sliding touch, up-sliding touch, down-sliding touch, single-click touch, double-click touch and long-press touch; the preset touch template stores left-right sliding threshold data, up-down sliding threshold data and clicking threshold data, the left-right sliding threshold data is a three-dimensional array and comprises X-direction data, Y-direction data and Z-direction data, and the left-right sliding threshold data is used for judging whether left-right sliding touch is performed or not; similarly, the up-down sliding threshold data and the clicking threshold data are also three-dimensional arrays, and include X-direction data, Y-direction data, and Z-direction data, which are respectively used to determine whether the up-down sliding touch and the clicking touch are performed.
Specifically, step S400 includes:
step S410, determining a maximum X-direction coordinate difference value, a maximum Y-direction coordinate difference value and a maximum Z-direction coordinate difference value based on the four-dimensional coordinate values of the sampling points;
in this embodiment, an X-direction coordinate difference value, a Y-direction coordinate difference value, and a Z-direction coordinate difference value between each sampling point are calculated, respectively, and a maximum X-direction coordinate difference value among all the X-direction coordinate difference values, a maximum Y-direction coordinate difference value among all the Y-direction coordinate difference values, and a maximum Z-direction coordinate difference value among all the Z-direction coordinate difference values are obtained.
Step S420, determining a touch type corresponding to the motion trajectory based on the maximum X-direction coordinate difference, the maximum Y-direction coordinate difference, the maximum Z-direction coordinate difference, and a preset touch template.
In this embodiment, left-right sliding threshold data, up-down sliding threshold data, and clicking threshold data are stored in the preset touch template, the maximum X-direction coordinate difference value, the maximum Y-direction coordinate difference value, and the maximum Z-direction coordinate difference value are matched with the preset touch template, and the touch type corresponding to the motion trajectory is determined according to the matching result.

The motion track of the user finger is obtained through the tracking mode of the intelligent terminal, the four-dimensional coordinates of the sampling point on the motion track are matched with the preset touch template, the touch type is further determined, and the fact that the opening position of the camera under the screen can respond to screen touch operation is achieved.
Based on the first embodiment, referring to fig. 3, a second embodiment of the screen touch management method of the present invention is provided, in this embodiment, step S420 includes:
step S421, when it is determined that the maximum X-direction coordinate difference is greater than the maximum Y-direction coordinate difference and the maximum X-direction coordinate difference is greater than the maximum Z-direction coordinate difference, acquiring the left-right sliding threshold data;
in this embodiment, when a finger touches a screen position of the front camera opening from the right and left, and a range blocked by the finger changes from the right half- > all- > left half, it is determined as a left-sliding touch event, a coordinate change in the X direction of a motion trajectory corresponding to the left-sliding touch event is the largest, and there is a slight change in the Y direction and the Z direction. Similarly, when the finger touches the position of the screen with the opening of the front camera from left and right, and the range shielded by the finger changes from left half- > all- > right half, the right sliding touch event is determined to be a right sliding touch event, the coordinate change of the motion track corresponding to the right sliding touch event in the X direction is the largest, and the Y direction and the Z direction have small changes. Therefore, when it is determined that the maximum X-direction coordinate difference is greater than the maximum Y-direction coordinate difference and the maximum X-direction coordinate difference is greater than the maximum Z-direction coordinate difference, it may be preliminarily determined that the current touch is a left-sliding touch or a right-sliding touch, so that left-right sliding threshold data in the preset touch template is obtained.
Step S422, when it is determined that the maximum X-direction coordinate difference, the maximum Y-direction coordinate difference, and the maximum Z-direction coordinate difference match the left-right sliding threshold data, it is determined that the touch type is left-right sliding touch or right-right sliding touch.
In this embodiment, whether the maximum X-direction coordinate difference, the maximum Y-direction coordinate difference, the maximum Z-direction coordinate difference, and the left-right sliding threshold data are matched is further determined, when the data are matched, left-sliding touch or right-sliding touch can be further determined, and when the data are not matched, the current motion trajectory corresponds to one-time invalid touch, and the intelligent terminal does not perform any operation.
Specifically, step S422 includes:
step a, acquiring a first sampling point and a second sampling point corresponding to the maximum X-direction coordinate difference value, wherein the X-direction coordinate of the first sampling point is larger than the X-direction coordinate of the second sampling point;
in this embodiment, when the maximum X-direction coordinate difference, the maximum Y-direction coordinate difference, and the maximum Z-direction coordinate difference match the left-right sliding threshold data, it is further determined whether left-sliding touch or right-sliding touch is currently performed. Specifically, two sampling points corresponding to the maximum X-direction coordinate difference are obtained: and setting the X-direction coordinate of the first sampling point to be larger than that of the second sampling point, and further comparing the time corresponding to the two sampling points.

in this embodiment, if the touch type is right-slide touch, that is, if the touch type is right-slide touch, the X-direction coordinate of the sampling point with the earlier track time is smaller than the X-direction coordinate of the sampling point with the later track time.
And c, when the track time of the first sampling point is earlier than the track time of the second sampling point, determining that the touch type is left-sliding touch.
In this embodiment, if the touch is left-sliding touch, that is, if the touch slides along the negative X coordinate direction, the X-direction coordinate of the sampling point with the earlier track time is greater than the X-direction coordinate of the sampling point with the later track time, so that when the track time of the first sampling point is earlier than the track time of the second sampling point, it is determined that the touch type corresponding to the current motion track is left-sliding touch.
In the screen touch management method provided by this embodiment, when it is determined that the maximum X-direction coordinate difference is greater than the maximum Y-direction coordinate difference and the maximum X-direction coordinate difference is greater than the maximum Z-direction coordinate difference, the left-right sliding threshold data is obtained, and then when it is determined that the maximum X-direction coordinate difference, the maximum Y-direction coordinate difference, and the maximum Z-direction coordinate difference match the left-right sliding threshold data, it is determined that the touch type is left-right sliding touch or right-right sliding touch, and thus it is accurately determined that the touch type is left-right sliding touch or right-right sliding touch, and it is achieved that the position where the camera is opened under the screen can respond to the screen touch operation.
Based on the second embodiment, referring to fig. 4, a third embodiment of the screen touch management method of the present invention is provided, in this embodiment, step S420 further includes:

in this embodiment, when a finger touches a screen position of the opening of the front camera from the bottom and the top, and a range shielded by the camera is changed from the bottom half- > all- > top half, it is determined that the touch event is a single slide-up touch event, a coordinate change of a motion trajectory in the Y direction corresponding to the touch event is the largest, and the X direction and the Z direction are slightly changed. Similarly, when the finger contacts the screen position of the front camera opening from top to bottom and the range shielded by the finger is changed from the upper half- > all- > lower half, the camera is judged to slide down the touch event at one time, the coordinate change of the motion track corresponding to the slide down touch event in the Y direction is the largest, and the X direction and the Z direction are slightly changed. Therefore, when the maximum Y-direction coordinate difference is greater than the maximum X-direction coordinate difference and the maximum Y-direction coordinate difference is greater than the maximum Z-direction coordinate difference, it may be preliminarily determined that the current touch is an up-sliding touch or a down-sliding touch, so that up-and-down sliding threshold data in the preset touch template is obtained.

In this embodiment, whether the maximum X-direction coordinate difference, the maximum Y-direction coordinate difference, and the maximum Z-direction coordinate difference are matched with the up-down sliding threshold data is further determined, when the data are matched, an up-sliding touch or a down-sliding touch may be further determined, and when the data are not matched, the current motion trajectory corresponds to an invalid touch, and the intelligent terminal does not perform any operation.
Specifically, step S424 includes:
step d, acquiring a third sampling point and a fourth sampling point corresponding to the maximum Y-direction coordinate difference value, wherein the Y-direction coordinate of the third sampling point is larger than that of the fourth sampling point;

in this embodiment, if the touch is a slide-up touch, that is, the touch slides along the Y-positive coordinate direction, the Y-direction coordinate of the sampling point with the earlier track time is smaller than the Y-direction coordinate of the sampling point with the later track time, so that when the track time of the third sampling point is later than the track time of the fourth sampling point, it is determined that the touch type corresponding to the current motion track is a slide-up touch.
And f, when the track time of the third sampling point is earlier than that of the fourth sampling point, determining that the touch type is gliding touch.
In this embodiment, if the motion trajectory is a downslide touch, that is, the motion trajectory slides along the Y negative coordinate direction, the Y-direction coordinate of the sampling point with the earlier trajectory time is greater than the Y-direction coordinate of the sampling point with the later trajectory time, so that when the trajectory time of the third sampling point is earlier than the trajectory time of the fourth sampling point, it is determined that the touch type corresponding to the current motion trajectory is a downslide touch.
In the screen touch management method provided by this embodiment, when it is determined that the maximum Y-direction coordinate difference is greater than the maximum X-direction coordinate difference and the maximum Y-direction coordinate difference is greater than the maximum Z-direction coordinate difference, the up-and-down sliding threshold data is obtained, and then when it is determined that the maximum X-direction coordinate difference, the maximum Y-direction coordinate difference and the maximum Z-direction coordinate difference match the up-and-down sliding threshold data, it is determined that the touch type is an up-sliding touch or a down-sliding touch, and it is further accurately determined that the touch type is an up-sliding touch or a down-sliding touch, so that the position of the opening of the camera under the screen can respond to the screen touch operation.
Based on the third embodiment, referring to fig. 5, a fourth embodiment of the screen touch management method of the present invention is provided, in this embodiment, step S420 further includes:

Therefore, when the maximum Z-direction coordinate difference is greater than the maximum X-direction coordinate difference and the maximum Z-direction coordinate difference is greater than the maximum Y-direction coordinate difference, it may be preliminarily determined that the current touch is a click touch, so that click threshold data in the preset touch template is obtained.
