3D measurement apparatus by using virtual camera model and two cameras, and method thereof

摘要

This invention provides a three-dimensional shape of the object to be measured using a single pattern syringe and two cameras A method of measuring, in the first step of scanning the fringe pattern on the object to be measured in the pattern syringe, the first virtual camera using the camera and the pattern model of the syringe, but finding the candidate points having the 2 ambiguity by applying the principle of optical triangulation Step 2, the candidate points of the scanning by the second camera, and other stereo matching algorithm applied to the third step to obtain the corresponding points, and stereo using the constraints that apply to the camera to confirm the final corresponding point 2 ambiguity is removed 3d is composed of a fourth step of measuring the shape. The invention is based on an optical triangulation, the fringe pattern different from the pattern of the virtual camera model technique used to scan the syringe, the 2 ambiguity resolution parameters to fuse the stereo matching technology to equal each other or the other two using a camera so, it is possible to accurately measure the three-dimensional shape of the object.
