Abstract:
1. A method of obtaining three-dimensional information for one or more target objects is provided comprising: (a) selecting one or more target objects; (b) illuminating the one or more target objects using a first illuminating device at a distance X (c) illuminating the one or more target objects using a second illuminating device at a distance X (d) calculating the set of distances X′1 between the first and second illuminating devices, and the one or more target objects, based on the decay of intensities of the first and second illuminating devices over distances X (e) illuminating the one or more target objects using a third illuminating device at a distance X (f) illuminating the one or more target objects using a fourth illuminating device at a distance X (g) calculating the set of distances X′2 between the third and fourth illuminating devices and the one or more target objects based on the decay of intensities of illuminating devices over distances X (h) merging the set of distances developed by the set of distances X′1 between the first and second illuminating devices with the set of distances developed by the second set of distances X′2, thereby minimizing the effect of illuminating device shadowing; and wherein the decay of the illumination intensity over distance X is 1/x
