| Research Abstract |
We have investigated methods for camera calibration and image synthesis.
(1) Camera Calibration
We have developed a method for measuring width of blur at the feature points using a space filtering technique. From the experiments, we got the results that the proposed method was about 30 times faster than the previous method.
(2) Image Synthesis.
We have proposed several methods to generate CG images based on the non-perspective projection camera models which are different from ordinary pinhole camera model. We also applied our method to generate images based on the camera calibration, and estimated the height of the Hiroshima Atomic Bomb cloud. Experimental results showed the validity of our method.
