Problems solved by technology

[0005] 1) Due to the difference in the material of the object, the absorption of different light source bands is different, and a single light source will greatly limit the material of the measured object
[0006] 2) A single light source causes the lack and incompleteness of object imaging information
[0007] 3) The combination of multiple systems is required to complete the information collection of multiple spectral bands, and the later fusion is complex and has large errors

Abstract

The invention discloses a three-dimensional imaging system and method, and relates to the technical field of spectral imaging. A PC, a camera, a projector I and a projector II are involved, and a trigger control channel and a data transmission channel are arranged between the PC and the camera and between the projector I and the projector II. The projection light source wavebands of the projectorI and the projector II are different. The projector I can project structured light of a single waveband. The projector II can project structured light of various different wavebands. The camera is located between the projector I and the projector II. The camera, the projector I and the projector II can be adjusted in a lifting mode, and lenses of the camera, the projector I and the projector II can be adjusted horizontally and vertically. Projection focuses of the camera, the projector I and the projector II converge at one point. Structured light of multiple light source wavebands can be projected, the system and the method can be suitable for three-dimensional imaging of objects made of different materials, missing and incompleteness of imaging basic information of the objects can be avoided, information collection of multiple spectral wavebands can be achieved through a single system, later fusion is simple, and errors are small.

Description

technical field [0001] The invention relates to the technical field of spectral imaging, in particular to a multi-spectral structured light three-dimensional imaging system and method. Background technique [0002] Multispectral imaging technology is a remote sensing technology that appeared in the early 1960s. The selection of its band range and number of bands is directly related to the application target. By obtaining spectral information of several or more bands of ground objects, the target spatial information, The simultaneous acquisition of radiation information and spectral information can improve the comprehensive detection perception and identification of target characteristics, and greatly expand the target resolution and monitoring capabilities of remote sensing detection technology. [0003] Three-dimensional imaging is a technology that extracts three-dimensional information of an object through optical means, and can completely restore the three-dimensional fe...
