Abstract: Disclosed is a method and apparatus for providing an omni-directional stereoscopic image based on layer projection. According to an embodiment of the present disclosure, there is provided a method of providing an omni-directional stereoscopic image based on layer projection, the method including: obtaining a spatial-information-point set; and generating a layer image based on a spatial-information-point subset constructed for each of multiple layers, the layer image corresponding to each of the multiple layers, wherein the spatial-information-point subset constructed for each of two consecutive layers includes one or more duplicate spatial information points.
