Real-time 3D image system

The invention provides a real-time 3D image system. The system comprises an information collection device, an information processing device in communication connection with the information collection device, and a user-end device in communication connection with the information processing device. The user-end device comprises an image output device and an instruction input device, the image output device is connected to the information processing device to display 3D images of image information collected by the information collection device, and the instruction input device is in communication with the information processing device to collect control motion information of a user and further to control the information collection device to collection objects. The invention further provides a method comprising the following steps that (a) the information collection device is provided, and image information is collected; (b) the information processing device is provided, and information is processed; and (c) the user-end device is provided, the 3D images are displayed, and motion collection is controlled.
