Abstract (en)
[origin: WO2018110822A1] Disclosed are an image projection method and system in a theater equipped with a projection area of a curved surface and a plurality of projection apparatuses. Specifically, disclosed are an image projection method and system, which can define a plurality of projection apparatuses as one cluster by computing relative transform information between the projection areas of the plurality of projection apparatuses and can project a single image onto a curved projection area without distortion through the plurality of projection apparatuses by defining a relative relation between the reference projection apparatus of the cluster and the projection area of the original image.
