Interactive system based on CCD camera porjector technology

Abstract

The invention relates to an interactive system based on camera projector technology, belonging to the technical field of computers, comprising a camera, a projector, a computer, an interactive recognition module and a rendering module; wherein, the projector projects rendered picture to a setting area; the camera captures a fixed scene which is an area covering the projected picture of the projector; after the area is captured by the camera, the area of the projected picture is identified in the captured image, and the area is transmitted to the interactive recognition module for further analysis; the interactive recognition module analyzes the current position of person and movement information, and then the message is transmitted to the rendering module; the rendering module responds to the message input by the interactive recognition module, and corresponding animation creation and real-time rendering are completed. The invention has the advantages that: a more natural human-computer interaction mode is realized by computer vision and graphic technology; the cost is saved, and the application scope of the system is greatly improved.

Description

technical field [0001] The invention relates to a system in the field of computer technology, in particular to an interactive system based on camera projector technology. Background technique [0002] Virtual reality technology combines the simulated environment, visual system and simulation system into one, and uses sensing devices such as helmet-mounted displays, graphics glasses, data suits, stereo headsets, data gloves and foot pedals. The operator is connected with the three-dimensional virtual environment generated by the computer. The operator interacts with the virtual environment through the sensor device, and can obtain various perceptions such as vision, hearing, touch, etc. It is much easier and cheaper to use this virtual reality technology to modify the design of buildings, machinery, weapons, etc., and to implement technical operation training and military exercises. With the rapid development of computer graphics hardware, the quality of real-time rendering ...
