APPARATUS FOR CALCULATING MISALIGNMENT QUANTITY OF BEAM SENSOR
First Claim
1. A misalignment quantity calculating apparatus for calculating a misalignment quantity of a beam sensor, the misalignment quantity calculating apparatus comprising:
- an identity determining means for determining whether a first object detected by the beam sensor is identical to a second object detected by an image sensor, the beam sensor transmitting a probing beam and receiving an echo based on the probing beam to thereby detect the first object, the image sensor capturing an image and processing the image to thereby detect the second object; and
a misalignment quantity calculating means for calculating, as a misalignment quantity of the beam sensor, an angle between a first line segment and a second line segment when it is determined that the first object is identical to the second object, the first line segment connecting a predetermined reference point of the misalignment quantity calculating apparatus and a first feature point of the first object, the second line segment connecting the predetermined reference point and a second feature point of the second object.

Abstract
The misalignment quantity calculating apparatus determines whether a first object detected by a beam sensor is identical to a second object detected by an image sensor. Upon determining that the first object is identical to the second object, the misalignment quantity calculating apparatus calculates, as a misalignment quantity of the beam sensor, an angle between a first line segment and a second line segment; the first line segment connects a predetermined reference point of the misalignment quantity calculating apparatus and a first feature point of the first object, and the second line segment connects the predetermined reference point and a second feature point of the second object.
