Abstract:
1. A method of generating a pattern constructed by more than 3 basic colors to acquire 3D color information, wherein a common light source and a pattern light source are used to respectively acquire a projected image and a pattern image to obtain a 3D model of an object, wherein the pattern light source provides the pattern constructed by more than 3 basic colors, comprising: (a) selecting a primary encoding unit including a predetermined number of colors; (b) adding a first of the more than 3 basic colors behind the primary encoding unit to form a first new encoding unit; (c) confirming that an arrangement of the first new encoding unit follows a predetermined color sequence of adjacent colors; (d) determining whether or not the first new encoding unit corresponds to any previous encoding unit; (e) one of (f) determining whether or not the final new encoding unit can be associated with a pre-existing cluster in accordance with a predetermined association parameter; (g) one of (h) repeating the steps (a) through (g) until all of the more than 3 basic colors are processed.
