Abstract
The measurement of body contours grating fringe projection technology is the three-dimensional measurement of a hotspot. Basic principle is to be tested based on grating projection three-dimensional object shape; key technology is to enable the generation of sinusoidal grating projection stripes projected onto the measured object. Theoretical sinusoidal intensity stripes should be a phase grating, but such grating is difficult and costly. Therefore, this paper structure of smooth three-dimensional measurement system, the core scanning devices-grating, through the characterization method to design a production, and enable it to project a stripe of light intensity by the sine distribution is given the experimental results. From the start of the study to refine and perfect the final three stages, each stage is accompanied by a large number of experiments. Using Fresnel-Kirchhoff formula. The overall structure of the grating design and the gradual improvement,Achieved good results, And proposed future research ideas and program,Also gives the experimental data and results.
