Abstract
In one embodiment, the present invention is a camera calibration tool. One embodiment of a three-dimensional test target for calibrating an image capturing device includes a first planar face exhibiting a first color, a second planar face exhibiting a two-toned pattern of a second color and a third color, and a third planar face exhibiting the two-toned pattern of the second color and the third color, wherein the first planar face, the second planar face, and the third planar face meet at a first right-angle convex vertex.

A three-dimensional test target for calibrating an image capturing device, comprising:
- a first planar face exhibiting a first color;
- a second planar face exhibiting a two-toned pattern of a second color and a third color;
- and
- a third planar face exhibiting the two-toned pattern of the second color and the third color,
- wherein the first planar face, the second planar face, and the third planar face meet at a first right-angle convex vertex.
An apparatus for calibrating an image capturing device, comprising:
- a cube-shaped body, the cube shaped body comprising:
- six faces;
- and
- eight vertices, such that three of the six faces meet at each of the eight vertices,
- wherein three of the six faces are colored black, one of the six faces is colored gray, and two of the six faces are colored half white and half gray.
