Embodiment Construction

[0053] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] This embodiment of the invention realizes the function of scanning objects close to the screen of the touch screen. For the specific structure diagram, see figure 1, we can install a camera in the rear projection case, the focal length of the camera is constant, and the shooting range is the entire screen; when we put an object such as a book close to the touch screen, the screen scanning function of the device is turned on; after the screen scanning function is turned on, The screen used for projection will automatically shrink down, which is convenient for the camera to take a clear picture of the object; use the multi-touch method to set the points P1, P2, P3, and P4 according to the shape (rectangle) close to the object; the screen captured by the camera The image and touch system analyzes the shape information of the obje...

Abstract

The invention relates to the screen scanning technology, in particular to a screen scanning method for a touch screen and a system thereof. The method comprises the steps of: (1) automatically starting a screen scanning function by a multi-point touch technology or manually starting the screen scanning function; (2) after the screen scanning function is started, starting an object shape confirmation program for confirming object shapes; (3) starting a photographing program to photograph the object shapes conformed in the step (2); and (4) performing image data processing on the photographed images. The invention provides a method for scanning objects with different shapes and sizes on an electronic device with a touch screen by using a camera and the multi-point touch technology.

Description

technical field [0001] The invention relates to screen scanning technology, in particular to a touch screen screen scanning method and system thereof. Background technique [0002] With the development of society, the application scope of electronic equipment with touch screen is constantly expanding.
