A light filtering and supplementing structure for a hand-held laser three-dimensional scanner, comprising a light filtering device (03) for selecting light of a specific wavelength band in front of a camera lens (01) and a highlight supplementary light generator (05) for illuminating marking points. The light filtering device (03) is located at a front end of the camera lens (01) and fixedly installed on the camera lens (01). The highlight supplementary light generator (05) is fixedly installed around an outer periphery of the camera lens (01) and annularly distributed around the light filtering device (03). The light filtering device (03) has the same wavelength band of light with the highlight supplementary light generator (05). The light filtering and supplementing structure for the hand-held laser three-dimensional scanner has high precision and good stability. |
