| Research Abstract |
A high precision 3D shape measurement method in consideration of the application for medical close range finder was developed. A fish-eye camera with very large depth of field and very wide optic angle was used to enlarge the degree of freedom of measuring distance. By the first step, a high precision calibration method of fish-eye camera was developed to acquire high precision space vectors from high distortion fish-eye camera images. Next, a high precision extraction method of space vectors beyond the object surface from minor camera images named brightness ratio method was developed. The new high precision 3D shape measurement method using fish-eye camera images from free and multiple viewpoints was developed using these technologies.
