Abstract:
The present invention provides a projection method, a projector and a projection system of fully covering a multi-directional circular-screen. The projection method obtains a circular-screen projection surface by dividing a visual platform to be projected; arranging each optical machine according to minimum optical path distance information. Each optical machine to be arranged projects an image onto each circular-screen projection surface to obtain a first projection coverage range; and adjusts the first projection coverage range according to setting parameters corresponding to each optical machine to be arranged according to a preset projection surface to obtain a second projection coverage range. The system calculates geometric parameters and the second projection coverage range of each optical machine to be arranged to obtain a spatial position and a rotation angle range of each optical machine to be arranged.
