A three-dimensional scanning method including a laser of a plurality of different wavelengths,

摘要

The present invention relates to a three-dimensional scanning method comprising a plurality of different wavelength lasers, wherein the scanner implementing the three-dimensional scanning method comprises a camera with at least two fixed positions and at least two laser projectors, The projector corresponds to at least two different wavelengths and is given a calibration of the spatial positional relationship of two cameras and the 3D scanning method is based on the 2D pattern of the laser contour projected onto the surface of the scanned object photographed by the two cameras After the two-dimensional lines centered on the highlight are respectively identified and acquired, three-dimensional point cloud data are acquired through the trigonometry principle and the epipolar constraint principle. The present invention also provides a scanner that implements a three-dimensional scanning method that includes a plurality of different wavelength lasers. The present invention includes a plurality of other wavelengths, which is good in applicability, greatly increases the function of a single scanner, and improves the false ratio.
