Abstract:
The present invention provides a projection method, equipment and system for achieving short focal length circular-screen output based on multiple optical machines. The projection method includes: setting a plurality of optical machines corresponding to one visual plane; calculating a value range of a throw ratio of the optical machines corresponding to the visual plane according to a percentage of a fusing zone formed when projection of the optical machines intersects each other and is projected to the corresponding visual plane and an expected screen ratio; obtaining setting parameters of each optical machine based on the value range of the throw ratio of each optical machine; and obtaining a spatial position and a rotation angle range for when the optical machines are projecting based on the setting parameters of the optical machines and a projection area of an optical path coverage range of the optical machines on the corresponding visual plane.

Claim (Index 5):
The projection method for achieving short focal length circular-screen output based on multiple optical machines according to  claim 1 , wherein according to the setting parameters of each of the plurality of optical machines and the projection area of the optical path coverage range of each of the plurality of optical machines on the corresponding one of the plurality of visual planes, obtaining the spatial position and the rotation angle range when each of the plurality of optical machines is projecting comprises:\n according to an area of each of the plurality of optical machines corresponding to the one of the plurality of visual planes, adjusting a spatial horizontal plane position and a rotation angle of each of the plurality of optical machines to calculate whether the optical path coverage range of each of the plurality of optical machines is within an area of the one of the plurality of visual planes; and outputting the spatial horizontal plane position and the rotation angle range when the optical path coverage range of each of the plurality of optical machines is within the area of the one of the plurality of visual planes.
