Abstract:
1. A 3D information generator for use in an interactive interface comprising: a MEMS (Micro-Electro-Mechanical System) light beam generator including a light source for providing at least one dot light beam and a MEMS mirror reflecting the dot light beam to project a scanning light beam to an object, the object reflecting the scanning light beam to generate reflected light, wherein the scanning light has a predetermined pattern including regions of different colors, shapes, sizes, or densities, each of the different colors, shapes, sizes, or densities being uniquely identifiable and not the same as the rest regions of the predetermined pattern; an image sensor receiving reflected light, for sensing an image including the object to generate 2D image information; and a processor for generating distance information related to a distance between the object and the 3D information generator by triangulation calculation according to the reflected light from the object, wherein the triangulation calculation calculates the distance information according to a location of the predetermined pattern in the image sensed by the image sensor and a differentiation of the predetermined pattern with respect to colors, shapes, sizes, or densities, so as not to misjudge the distance, and wherein the distance information is combined with the 2D image information to generate 3D information.
