Abstract:
Objective To investigate the accuracy of three dimensional facial measurement system based on structured light projection, and explore the methods to reduce noise of the output images. Methods The known object for calibration was measured by the measurement system to correct the parameters of the system and enhance the measurement accuracy. The mechanism of noise was analysed, and the noise and sundry of the images were eliminated. Results The parameters of each assembly of system were obtained by calculation and calibrated, and the measurement accuracy (0.028 mm) of three dimensional facial measurement system based on structured light projection was increased. Application of image processing technology reduced the noise and sundry of output images. Conclusion The accuracy of three dimensional facial measurement system based on structured light projection is high. The image output is reliable, and can be clinically used in facial scanning and three dimensional reconstruction.
