Abstract
The present application provides a method and system for reconstructing transparent objects based on multi-wavelength light tracing, the method comprises calculating and obtaining a reverse light equation of one pixel point of a camera by using intrinsic parameters of camera calibration; placing a transparent object on a display screen, emitting, by a backlight lighting source, lights of two or more different wavelengths to the display screen, and recording, by the pixel point, position information of the lights of two or more different wavelengths on the display screen, respectively; translating the display screen along a direction perpendicular thereto, and calculating a rectilinear equation of light from a lower surface of the transparent object to the display screen of the lights of different wavelengths recorded by the pixel point.
