Claims22
A joint sensor calibration target comprising:
- a spherical portion;
- a cutout portion, wherein the cutout portion is formed within the spherical portion and comprises three equal surfaces;
- and
- a trihedral reflector positioned within the cutout portion.
A system for joint calibration of vision and radar sensors comprising:
- an autonomous device having at least one camera sensor and at least one radar sensor;
- and
- a calibration target configured to aid calibration of the at least one camera sensor and the at least one radar sensor simultaneously, wherein the calibration target comprises:
- a spherical portion;
- a cutout portion, wherein the cutout portion is formed within the spherical portion and comprises three surfaces;
- and
- a trihedral reflector positioned within the cutout portion.
A method of forming a calibration target for the joint calibration of vision and radar sensors for an autonomous device, the method comprising:
- forming a spherical portion;
- forming a cutout portion within the spherical portion, wherein the cutout portion is formed so as to comprise three surfaces of equal size and shape;
- and
- providing a metallic trihedral reflector positioned within the cutout portion.
