A parallel color confocal three-dimensional shape optical measurement system

Abstract

The invention relates to a parallel color confocal three-dimensional shape optical measurement system, which is characterized in that it comprises: a polychromatic light source, a spectroscopic module, a dispersion module, an object-loading module and an imaging device located on one side of the spectroscopic module, arranged in sequence from top to bottom module, the object to be measured is located between the dispersion module and the loading module, and the polychromatic light emitted by the polychromatic light source is split by the spectroscopic module and then propagated to the dispersion module for parallel dispersion, so that the rays of different wavelengths are focused on different axes of their respective axes according to the wavelength rule. At the height position, the light reaches the surface of the measured object and is reflected by the surface of the measured object into the spectroscopic module, and then the light is reflected again by the spectroscopic module, and the light of the wavelength focused on the surface of the measured object reaches the imaging module for imaging after reflection. The parallel color confocal three-dimensional shape optical measurement system of the present invention is convenient to use, and has high measurement efficiency and measurement precision.

Description

technical field [0001] The invention relates to the field of optical measurement, in particular to a parallel color confocal three-dimensional shape optical measurement system. Background technique [0002] With the development of science and technology and productivity, the requirements for the three-dimensional shape measurement of the object surface are getting higher and higher. There is a great demand, such as manufacturing industries such as mechanical vehicles, medical image measurement, space remote sensing, etc. In the field of medicine, the department of stomatology uses three-dimensional measuring instruments to measure teeth, the department of plastic surgery uses three-dimensional imaging of the appearance of human skin for scheme design and operation implementation, and the cardiac surgery uses detection and monitoring instruments to observe the dynamics of the heart in real time; in the field of industrial manufacturing, for The generated product is tested fo...
