Abstract

The invention discloses a novel interactive projection system, which comprises a video image projection unit, an image collection unit, an image data processing unit, a communication unit and a Flash interactive unit, wherein the video image projection unit is used for projecting interactive data, the image collection unit is used for collecting image data, the image data processing unit is used for carrying out distortion correction and perspective conversion on the collected image data, separating background images from moving images, updating the background images and dividing and trackingthe moving images, the communication unit is used for transmitting data coordinates of tracked images to the Flash interactive unit, and the Flash interactive unit is used for outputting corresponding Flash interactive effects according to the data coordinates of the tracked images. Through the infrared light projection technology and the image processing technology, the invention obtains and identifies control information input by operators, and transfers the control information to an expression module for realizing the non-contact type human-machine interaction. A correction template different from the traditional model is adopted, so the video correction is greatly improved. The image scene conversion adopts the high-efficiency perspective conversion technology, so the whole interactive process has convenient operation, high efficiency and high speed.
