Problems solved by technology

However, although this method is simple and does not require a large number of calculations, this identification method is very susceptible to the influence of different background lights, which will cause identification errors
The color saturation of those graphics templates stored in the memory in advance will change

Embodiment Construction

[0022] FIG. 1 is a schematic structural diagram of a system of a passive and interactive real-time image recognition method of the present invention. As shown in the figure, the system includes a personal computer 10, an image projection device 11, an image area 11a, a camera 12, and an image capture device. Card 13.

[0023] The invention provides a passive and interactive real-time image recognition method, and the main identification objects can be divided into two categories: passive and interactive. Among them, the difference between the passive type and the interactive type lies in the location of the image sensing area. Under the passive identification module, the position of the image sensing area is fixed; while in the interactive case, the opposite is true, and the sensing area changes within the range of the image projected by the image projection device.

[0024] The images captured by the present invention are all 8bits grayscale, and the grayscale value ranges f...

Abstract

A real time image identifying method of passive and interactive mode includes projecting image by projection device to set up 8bits grey level fixed background image being used as reference image, utilizing video camera to continuously pick up real time 8bits grey level image and reference image from image region projected out by said projection device then carrying out image subtraction and image binaryzation operation for enabling to quickly and accurately identify out activity of movable object.

Description

technical field [0001] The present invention is a passive and interactive real-time image recognition method, especially a real-time image recognition method that is not affected by environmental light sources and noise, and the real-time image recognition method of the present invention can be applied to various multimedia interactive advertisements, teaching , various entertainment games, electronic games and other extensive fields. Background technique [0002] Today's real-time image recognition technology mainly projects multimedia animation images through a single gun (or other imaging devices), and digitizes the obtained images through a camera and an image capture interface. [0003] Using correlation recognition technology to judge the area where a person's limbs touch the projected image, and make a relative response. The previous patent related to identification technology, U.S. Patent No. 5,534,917, uses the AND operator method to identify patterns. It mainly st...
