The utility model relates to a specular object measurement device based on binocular vision. A computer is connected with a liquid crystal display and a camera. The liquid crystal display is placed above a measured specular object. The liquid crystal display is used for receiving a computer control signal to generate sinusoidal fringe patterns and projecting the fringe patterns on the surface of the measured object. The computer is used for converting the fringe images, which are collected by the camera, of the surface of the measured object into the surface outline of the measured object. According to the utility model, the system structure is simple non-contact measurement can be realized various contact type measurement head in a traditional measurement technology are not needed the measurement cost is reduced and the measurement efficiency is improved.
