Claim 9:
10. A method of obtaining a high-resolution 3D image of an object, comprising steps of:
a) moving the object toward the intersection of a laser fan plane;
b) illuminating the object with a red laser light source;
c) illuminating the object with a blue laser light source;
d) illuminating the object with a green laser light source;
e) capturing a first color image of the object with a first camera;
f) simultaneously capturing a second color image of the object with a second camera;
g) simultaneously capturing a third color image of the object with a third camera, wherein each camera captures three lines that are projected across the object and the three lines provide three sets of point clouds, wherein each position is scanned three times from three lasers from different angles;
h) separating the first color image into a first monochrome image using the red laser light source, a second monochrome image using the blue laser light source and a third monochrome image using the green laser light source;
i) separating the second color image into a fourth monochrome image using the red laser light source, a fifth monochrome image using the blue laser light source and a sixth monochrome image using the green laser light source,
j) separating the third color image into a seventh monochrome image using the red laser light source, an eighth monochrome image using the blue laser source and a ninth monochrome image using the green laser light source;
k) converting the first monochrome image, the second monochrome image, the third monochrome image, the fourth monochrome image, the fifth monochrome image, the sixth monochrome image, the seventh monochrome image, the eighth monochrome image and the ninth monochrome image into point-cloud data; and
l) Creating a single high-resolution 3D image from the point-cloud data.
