Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below according to the drawings and embodiments. It should be understood that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0029] Such as figure 1 As shown, a method for selecting an area array camera positioning image effective area adjustment method includes steps:

[0030] S100, taking an image of the touch display screen when the user does not click the touch display screen, and storing it as a background image. The human-computer interaction platform starts, the touch correction software runs simultaneously, and the display screen displays a prompt message to remind the user not to touch the display screen. The positioning camera captures the image when the user does not touch the display screen, and stores it in the system as a...

Abstract

The invention provides a method for selecting an adjustment mode of an effective area of an area array camera positioning image, and a system using the method. A user clicks appointed positions in a touch display area in sequence, and enables a positioning camera to respectively take images of a display screen before and after the user clicks on the display screen; the taken images are automatically processed through a program; whether the present camera deviation can obtain an effective touch positioning area by adjusting parameters or not is judged, if so, the parameters are calculated and updated into a parameter list so as to realize the touch positioning, if not, the user is prompted that positioning equipment needs to adjust hardware equipment so as to realize positioning. By utilizing the method and the system for selecting the adjustment mode of the effective area of the area array camera positioning image, the simple selection and the automatic selection of the adjustment mode of the effective area of the area array camera positioning image are realized, so that the method and the system are applicable to use of vast users.

Description

technical field [0001] The invention relates to the field of image display, in particular to a method and a system for selecting an adjustment mode of an effective area of ​​an area array camera positioning image. Background technique [0002] Human-computer interaction is more and more widely used in the modern IT industry. Camera positioning touch technology is widely used in large-scale interactive display platforms due to its responsiveness, smooth writing, and simple structure and manufacturing. In the camera positioning touch technology, the area array camera has a large shooting range, adjustable shooting parameters such as shutter, gain, and aperture, and other advantages, which make the optical touch technology based on the area array camera have its special advantages. [0003] In the patent publication number CN101566897, when the area array camera is positioned, the effective long rectangular area corresponding to the touch border in the image captured by the ca...
