説明

This paper presents a novel projector selection method to improve the projected image quality on a solid object (such as fabricated 3D objects) in terms of spatial resolution for multi-projection system. The spatial resolution degradation of a projected image is mathematically represented as convolution of the point spread function (PSF) of each projected pixel and an original image. Previous researchers focused on the area or shape of the PSF, and chose a projector to display high resolution images on the solid object. However, the PSF information alone is not sufficient for the best projector selection, because the resolution of a projected result is dependent not only on the PSF but also the original image content. Therefore, we propose to select a projector that can display an image with the highest resolution by estimating the projected results from all projectors in the system, and evaluating how original image information is preserved in each estimated result. Through experiments, we confirmed that the proposed method provided projected results with better image qualities than conventional methods.
