Viewing range estimation method and viewing range estimation apparatus

摘要

PROBLEM TO BE SOLVED: To obtain a range in which a subject projected onto a two-dimensional plane looks natural.SOLUTION: A three-dimensional model of a subject 100 is mapped with the subject 100 photographed in a video and a portion photographed in the video in the three-dimensional model is specified. When the three-dimensional model is viewed from each view point, an area α that is visible from the view point and imaged in the video, an area β that is invisible from the view point and imaged in the video, and an area γ that is visible from the view point and not imaged in the video are extracted and a viewing range is determined based on a rate of areas α, β, and γ of each view point. Thus, a range in which a video 200 of the subject 100 projected on a projection environment looks natural can be known.SELECTED DRAWING: Figure 2
