Abstract
A calibration apparatus and method suitable for calibration of an offset sensor of a subject vehicle. The calibration apparatus comprises a reference structure that is placed into, a reference locus using image data generated by a camera associated with the reference structure. An offset-target structure is then placed into position by coupling the offset-target structure to the reference structure, the coupling providing an appropriate locus for the offset-target structure during calibration of the offset sensor. The coupling restricts the linear and rotational displacement of the offset-target structure during calibration.
Claims16
A calibration apparatus for an offset sensor of a subject vehicle, the apparatus comprising:
- a reference structure having a horizontal member, the horizontal member disposed in a direction parallel with a horizontal plane;
- a camera configured to be coupled to the reference structure and operable to generate image data depicting the subject vehicle;
- and
- an offset-target structure having a guide arm and configured to be detachably coupled to the horizontal member such that the guide arm interfaces with the horizontal member,
- wherein the calibration apparatus is configured for a calibration procedure of the offset sensor when the reference structure is positioned relative to the subject vehicle based upon image data generated by the camera and the offset-target structure is coupled to the horizontal member.
A method for placing an offset-target structure into a locus suitable for calibration of an offset sensor of a subject vehicle, the offset-target structure having a guide arm, the method comprising:
- positioning a reference structure into a reference locus, the reference structure having a horizontal member and a camera, the reference locus defined in relation to the vehicle and found using image data generated by the camera depicting the subject vehicle;
- and
- coupling the offset-target structure to the reference structure such that the guide arm interfaces with the horizontal member,
- wherein the reference locus is found using image data generated by the camera and
- wherein the guide arm restricts the motion of the offset-target structure with respect to pitch, yaw, or roll when the offset-target structure is coupled to the reference structure.
