Embodiment 1

[0036] figure 1 A schematic flow chart of the first touch positioning method provided by the embodiment of the present application is shown, and the details are as follows:

[0037] In S101, the three-dimensional information of the touch point detected on the target touch area is obtained by using a depth camera, the depth camera is located outside the target touch area, and the shooting direction of the depth camera is the target touch point The coordinate origin of the control area points to the direction of the center point of the target touch area.

[0038] The target touch area is the area that receives touch operations (click and swipe operations by the user), and the target touch area can be the screen of a designated terminal device (such as a computer, TV, mobile phone, etc.), an LED electronic display, a billboard, etc. , the outer surface of a glass cabinet, a projection screen, a projection wall, or a surface area on any material object such as a wooden board, the...

Embodiment 2

[0062] image 3 A schematic flowchart of the second touch positioning method provided by the embodiment of the present application is shown, and the details are as follows:

[0063] In S301, a depth camera is set on a plane to be detected.

[0064] The plane to be detected is the plane on the specified target object, for example, the screen of terminal equipment (such as computer, TV, mobile phone, etc.), LED electronic display, billboard, glass cabinet, projection screen, projection wall or wood, etc. The plane of the outer surface of the target object. A depth camera is set on the plane to be tested, so that the depth camera can capture touch points on the plane to be tested.

[0065] In S302, the shooting area of ​​the depth camera is set, and the vertical distance from each point in the shooting area of ​​the depth camera to the plane to be detected is less than a preset distance and greater than or equal to 0.

[0066] Set the shooting area of ​​the depth camera. The v...

Abstract

The invention is suitable for the technical field of touch control, and provides a touch control positioning method and device and terminal equipment. The method comprises the steps: obtaining the three-dimensional information of a touch control point detected on a target touch control region through a depth camera which is located outside the target touch control region, wherein the shooting direction of the depth camera is the direction that the origin of coordinates of the target touch area points to the central point of the target touch area; based on the three-dimensional information of the touch point, calculating the included angle between the vector where the touch point is located and the vector where the horizontal coordinate axis of the target touch area is located, wherein thevector where the touch point is located is the vector pointing to the touch point from the origin of coordinates of the target touch area; obtaining coordinates of the touch point on the target toucharea based on the three-dimensional information of the touch point and the included angle. According to the method disclosed in the invention, the touch control positioning cost can be reduced.

Description

technical field [0001] The invention belongs to the field of touch technology, and in particular relates to a touch positioning method, device and terminal equipment. Background technique [0002] With the development of science and technology, touch technology is more and more widely used. For example, smart terminals such as mobile phones and tablet computers are inseparable from the support of touch technology. Users can trigger corresponding functions by performing touch operations on the terminal screen. [0003] Existing touch technologies generally integrate capacitive or resistive touch screens on smart terminals, or integrate infrared positioning systems, so as to identify and locate the user's touch gestures on the screen and trigger corresponding operations. However, these two methods require pre-integrated components on the terminal equipment, which have the defects of high hardware cost and low precision. Contents of the invention [0004] In view of this, th...
