Abstract :
A 3D camera based on the differential absorption of light by a colored liquid is described. The range image is obtained from two illuminance images taken at two different wavelengths. The theoretical aspects of range-from-absorption are discussed in detail. Practical considerations for the calibration and implementation of the method are also covered. The accuracy of the 3D camera is discussed, and experimental results are presented
