Other AbstractThe invention relates to a mirror object measuring device and a method based on binocular vision. According to the device, a computer is connected with a liquid crystal display device and a camera, and the liquid crystal display device is arranged above a measured mirror object. The measuring method comprises steps that: a binocular camera is calibrated, an internal matrix of the binocular camera and a rotating translation matrix between the cameras are acquired, and relative position relations between the liquid crystal display device and the binocular camera are acquired; a sine fringe is generated by the computer, the liquid crystal display device is controlled to project an image of the sine fringe to the measured mirror object, and a virtual image which is formed on a surface of the measured mirror object and is generated by the sine fringe shot by the camera is inputted to the computer; information of the virtual image acquired by the camera is processed by the camera according to the calibrated relative position relations and the internal matrix of the camera to acquire a three-dimensional profile of the surface of the measured mirror object. The mirror object measuring device has a simple structure, can realize non-contact measurement, needs no contact probes in the traditional technology, reduces measurement cost and improves measurement efficiency.
