Real-time system for acquiring 3D information

A system architecture based on structured light and quick algorithms of image processing is introduced. The system adopts master\|slave architecture. Its slave system based on DSP can process real\|time image concurrently. It can complete image segmentation and obtain the information of laser beam and contour image once in 80ms. This system increases greatly sampling speed to 18000 points per second so as to show 3D real\|time image on computer. Furthermore, it can hold perfect performance and its price is low. At the same time, system memories and requirements are reduced. Our design takes advantage of hardware and software effectively. It is superior to other overseas and domestic products. In addition, the system performance and technology target are summarized finally. The system avail specially for mechanical long distance manufacture, fast mixed rangs, virtual reality and 3D electrograph. The research is important for production and application.
