摘要： A digitizer combining functions of stereovision, color 3D digitizing and motion capture of a target object. The digitizer has a base supporting two cameras and two projection arrangements with projectors, one of which is provided with a grating element for projection of an encoded pattern on a surface of the target object and used for an active 3D range sensing, the other being used for an acquisition of texture information of the target object. The cameras and the light projectors are angled with respect to each other and arranged so that they have optical axes converging through a single point. A computer operates the projectors and processes the video signals generated by the cameras according to the selected function.

摘要： An optical 3D digitizer for digitizing an object, comprises a white light source producing white light, a projection lens projecting the white light toward the object whereby the object has a fully illuminated side, a grating device producing a fringe pattern in the light projected by the projection lens, and first and second cameras positioned aside from the projection lens and aligned in angled directions with respect to each other so that the cameras have complementary fields of view directed on the illuminated side of the object and partially overlapping with each other over a depth of measurement of the object. The cameras have respective video outputs to produce video signals representing complementary images of the object with a common image portion as a result of the fields of view being partially overlapping.
