Abstract (in Japanese) (See Japanese page) 
(in English) When an image is projected onto a non-planer surface, the resolution is not spatially uniform due to the distortion of prijected image.
We propose to insert a transparent layer between a projector and a non-planar surface and optimize its shape to make the projection pixel density spatially uniform, which can be controlled by non-uniformly refracting a projection light through the transparent layer.
We use a multi-material 3D printer to fabricate the transparent layer combined with a non-planar surface.
From the result of a projection experiment with the surface, we validate our proposed method.
