Abstract
Provided is a method capable of extending viewport range of a single projector and automatically tracking a moving object in a space-augmented reality system. The method utilizes a disc-shaped rotating base capable of automatically feeding a rotating angle back, the single projector is fixed on the disc-shaped rotating base, and an optical axis of the projector is coincided with an axis of the disc-shaped rotating base. A projection matrix of the projector is simultaneously confirmed and dynamically updated according to a rotation matrix of the projector and a translation matrix of an object. The multiplying order of the matrixes includes that the rotation matrix is multiplied by the current projection matrix, and then multiplied by the translation matrix of the object to acquire a new projection matrix.
