Abstract
A jig according to the present disclosure includes N planes (N is an integer equal to or larger than 4) respectively attached with patterns, in which−90°<θ<90°  (1)0≠0  (2)where θ is an angle formed by, with respect to a reference normal vector perpendicular to a jig reference plane, the jig reference plane being one plane among the N planes, and having a direction from the jig reference plane toward a space in which the stereo camera is disposed, a non-reference normal vector perpendicular to a non-reference plane different from the jig reference plane among the N planes and having a direction from the non-reference plane toward the space in which the stereo camera is disposed. Non-reference normal vectors corresponding to N−1 non-reference planes among the N planes have directions different from one another with respect to the reference normal vector and do not have directions symmetrical with respect to the reference normal vector.
