Claim One:
1. A method of measuring a depth map for an object, comprising: positioning multiple projectors at respectively multiple angular positions relative to the object, wherein each of the projectors comprises color channels whose colors differ from that of others of the multiple projectors; positioning an image capture device relative to the multiple projectors, wherein the image capture device comprises a multispectral capture device having a capture sensitivity spectral range that includes the spectral range of the totality of colors of the multiple projectors; projecting a first combined color pattern onto the object using the multiple projectors, wherein each projector projects a color striped pattern whose resolution differs from that of others of the projectors, and wherein the resolution of the color striped pattern is related to the angular position of the projector and is characterized by a minimum stripe width such that a small minimum stripe width corresponds to a high resolution pattern and a large minimum stripe width corresponds to a low resolution pattern; capturing an image of the object with the first combined color pattern using the image capture device; and recovering the depth map of the object by calculations using the captured image.
