Abstract
The invention provides a true three-dimensional panoramic display and interactive device without calibration, which comprises a main support, a helmet-mounted display, an image storage processor and a host computer. The main support is provided with a holder used for installing a plurality of cameras. The cameras are arranged on the holder. An observer standing in the inner space of the main support can watch a virtual scene in real time through the helmet-mounted display. The observer can move freely in the space including turning the head, walking and turning freely. The observer can interact with the scene in real time. The image information of the observer is collected through the plurality of cameras. After images are preprocessed, the host computer analyzes, matches and calculates a plurality of images to get the information of positions, poses and actions of the observer in real time. In this way, corresponding change of the virtual scene in the helmet-mounted display can be controlled to achieve visual display and interactive effect. Without calibrating the observer, the observer can turn the head and body naturally to change the view point, thus achieving true three-dimensional panoramic display and interaction. The invention has the advantages of better immersion and flexibility.
