Analytical compensation of inter-reflection for pattern projection
Yasuhiro Mukaigawa, Takayuki Kakinuma, Yuichi Ohta · 2006
If a pattern is projected onto a concave screen,the desired view cannot be correctly observed due to the influence of inter-reflections. This paper proposes a simple but effective technique for photometric compensation in consideration of inter-reflections. The compensation is accomplished by canceling inter-reflections estimated by the radiosity method. The significant advantage of our method is that iterative calculations are not necessary because it analytically solves the inverse problem of inter-reflections.
