Abstract

The invention discloses an integrated three-dimensional measurement system and a measurement method. The measurement system comprises a housing, wherein the top surface and the front surface of the housing are open; a projection hole and a camera mounting hole are respectively formed in the bottom surface of the housing; a CMOS camera is mounted in the camera mounting hole; sliding grooves are formed in two opposite side surfaces of the housing; a device mounting plate is mounted on the sliding grooves; and a controller is arranged on the device mounting plate. The measurement method comprisesthe following steps: generating a phase shift structured light pattern with sinusoidal brightness changing with time by the controller, obtaining a brightness time table corresponding to the light pattern, and transmitting the brightness time table to a semiconductor laser. The problem that a three-dimensional measurement device in the prior art is difficult to be suitable for a space-limited environment can be solved, and the system is high in environmental adaptability, high in reliability and accurate in measurement.

Description

technical field [0001] The invention relates to the technical field of three-dimensional measurement, in particular to an integrated three-dimensional measurement system and a measurement method. Background technique [0002] In recent years, surface profile measurement has become increasingly important in a variety of industrial applications. In fields such as industrial design / inspection, anthropometry and biomedical applications, 3D profilometry has become one of the popular tools. Especially in the design and inspection process in the aerospace field, a compact, portable or hand-held and lightweight high-precision three-dimensional measurement system is required, which puts forward higher requirements for three-dimensional measurement. [0003] The hardware components of the three-dimensional measurement system based on active structured light mainly include structured light fringe projection equipment and image acquisition equipment. The technical solution usually ado...
