Outline of Final Research Achievements

Active stereo methods can measure an object no matter with or without textures on its surface robustly against changes of light environment. The active stereo methods perform 3D measurement by projecting multiple pre-designed pattern lights on the object with a projector and capturing the reflected light with a camera. However, it is difficult for the existing active stereo methods to measure the objects with different optical properties with high accuracy and to perform 3D measurement robustly against changes from assumed optical characteristics.
To solve this problem, we have proposed a novel method of 3D measurement with feedback projection. The proposed method computes the pattern lights dynamically based on the feedbacked images captured by the camera.
