Interactive projecting system and implementation method for same

Abstract

The invention discloses an interactive projecting system and an implementation method for the same. The implementation method includes: firstly, capturing image information of a computer display screen projecting on a screen; secondly, corresponding a coordinate of the captured image information to that on the computer display screen; thirdly, extracting position information of a cursor from the image information captured by a video acquisition device; fourthly, calculating a coordinate position of the cursor on the computer display screen corresponding to a coordinate position of the cursor in the image information; and fifthly, recognizing flashing information of the cursor and generating corresponding mouse actions. By the aid of the interactive projecting system and the projecting method for the same, all operation of a mouse can be completely simulated, and by means of a simple and visualized image processing method, a position of a laser pointer light spot can be easily detected, so that the mouse cursor is precise in positioning, and real interaction of the system is realized.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to an interactive projection system and its realization method. Background technique [0002] The projection system includes a projector and a computer. The projector is connected to the computer to project video signals output by the computer onto a screen. Currently, the projection system is widely used in various fields of production and life. [0003] The projection system in the prior art generally also includes a laser pointer, which uses the laser pointer to generate a laser beam that is focused and projected on the screen to play an indication role. With the development of interactive technology, in some fields, the function of the laser pointer is no longer limited to the pointing function, but also can play the corresponding mouse function. For example, during a PPT speech, the laser pointer can be used to realize the flip-down function, etc. Further, in the...

AI Technical Summary

Problems solved by technology

[0007] In view of the shortcomings of the prior art above, the purpose of the present invention is to provide an interactive projection system and method to solve the problems that the interactive projection system in the prior art cannot really realize the mouse function and the accuracy of image processing is low.
