Abstract
An image processing apparatus includes a projection unit adapted to project pattern-light onto an object; an image capturing unit adapted to capture the object; a calculation unit adapted to calculate a line direction of the pattern-light in each predetermined region of the image; a decision unit adapted to decide an epipolar-line based on a relationship between the projection unit and the image capturing unit; a determination unit adapted to determine whether an angle made by the direction of the epipolar-line and the line direction is not more than a predetermined value; and a detection unit adapted to detect a first-region when the angle is not more than the predetermined value, and detect a second-region when the angle is more than the predetermined value. The projection unit projects the pattern-light having a line component parallel to the epipolar-line.
