The invention relates to a surface type measuring device adopting laser rotary scanning.The surface type measuring device is composed of a one-dimensional sliding table system, a laser rotary scanning system and a binocular vision measuring system.The one-dimensional sliding table system is composed of a first rotary stepping motor, a motor supporting seat, a coupler, a front supporting block, a ball screw, unthreaded shafts, a linear sliding table, a rear supporting seat and a base.The laser rotary scanning system is composed of a screw, a screw sleeve, connecting rods, a laser device sleeve, a laser device, a second rotary stepping motor, a polyhedron rotary mirror and a motor support.The binocular vision measuring system is composed of a bottom plate, cameras, supporting rods and set screws.According to the surface type measuring device, the second rotary stepping motor is used for driving the polyhedron rotary mirror to rotate, a laser emitted by the laser device irradiates a reflecting mirror of the polyhedron rotary mirror, and the laser point is reflected by the reflecting mirror and irradiates on a measured surface.The two cameras shoot the laser point irradiating the measured surface at the same time, a computer controls the shooting process of the two cameras and achieves real-time collecting and analyzing of shot data, and thus it is achieved that the computer controls output of three-dimensional coordinate points in binocular vision measuring.
