蛍光球体マーカを用いた三次元画像計測における校正用画像数の削減

抄録

3D image measurement technology can measure multiple points simultaneously over a wide area without contact with the object. Therefore, we propose a calibrator with eight fluorescent spherical markers that can detect millipixel and that are three-dimensionally. By using this calibrator, the number of calibration images, the number of arrangements, and the number of postures can be reduced compared to the conventional method. A 3D measurement simulation was performed to confirm that the relative accuracy of 10-6 order was comparable to that of the conventional method under the condition of 400 images with the number of calibration images reduced by 93%.
