Embodiment Construction

[0079] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0080] refer to figure 1 As shown, it is a schematic flow chart of an object recognition method based on an infrared screen according to an embodiment of the present invention. The object recognition method based on an infrared screen includes:

[0081] Step 101 , controlling the infrared emitting tube and the infrared receiving tube of the infrared touch screen to scan the touched object at regular intervals to obtain the outline of the touched object at each moment.

[0082] Step 102 , draw a common tangent line between the outlines of every two adjacent touching objects, and fill the area between the outlines of the two touching objects and the common tangent line.

[0083] As an embodiment of the present invention, a...

Abstract

The invention discloses an object identification method and device based on an infrared screen. The identification method comprises the following steps: controlling an infrared transmitting tube and an infrared receiving tube of an infrared touch screen to scan a touch object at set intervals to obtain the external contour of the touch object at each moment; and drawing a common tangent between the external contours of every two adjacent touch objects, and filling an area between the external contours of the two touch objects and the common tangent. Therefore, the object identification method and device based on the infrared screen can cause the infrared touch screen to identify and display the movement of regular or irregular objects.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method and device for object recognition based on an infrared screen. Background technique [0002] With the development of technology, infrared touch screen is more and more widely used. The existing technology is also gradually solving the problem of multi-point recognition on the infrared touch screen, but the current infrared touch screen cannot recognize and display the movement of regular or irregular objects. Contents of the invention [0003] In view of this, the object of the present invention is to propose a method and device for object recognition based on an infrared screen, which enables the infrared touch screen to recognize and display the movement of regular or irregular objects. [0004] Based on the above object, the present invention provides a method for object recognition based on an infrared screen, comprising steps: [0005] Control the infrared ...
