Title:
METHOD FOR ACQUIRING OPTIMAL SPHERICAL IMAGE BY USING MULTIPLE CAMERAS
Document Type and Number:
WIPO Patent Application WO/2018/066760
Kind Code:
A1
Abstract:
The present invention relates to a method for acquiring an optimal closed-curved image by using multiple cameras and, particularly, provides an image providing method for producing one image by using multiple cameras having different capturing viewpoints and fixed to a rig. To this end, the image providing method comprises: a projection step for acquiring one image by projecting images obtained by multiple cameras on a closed-curved projection surface, using parameter information; a rendering step for fitting the acquired one image into a quadrangular frame through a sampling procedure which is performed non-uniformly for each area; and a viewing step for mapping the sampled image to a viewing sphere.
