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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, equipment and system for achieving short focal length circular-screen output based on multiple optical machines","description":"The present invention provides a projection method, equipment and system for achieving short focal length circular-screen output based on multiple optical machines.
