Rotation deviation amount detection device, object detection sensor, rotation deviation amount detection system, rotation deviation amount detection method, and rotation deviation amount detection program

摘要

PROBLEM TO BE SOLVED: To provide a rotational deviation quantity detection device capable of detecting rotational deviation quantity of a plurality of object detection sensors for each object detection sensor, and an object detection sensor, a rotational deviation quantity detection system, a rotational deviation quantity detection method and a rotational deviation quantity detection program.SOLUTION: A rotational deviation quantity detection device has a registration part and a rotation detection part. The registration part registers correct answer data related to paths of objects 130-1 through 130-6 and the paths. The rotation detection part detects rotational deviation quantity of a plurality of object detection sensors with respect to a predetermined direction on the basis of comparison results of detection information representing results obtained by the plurality of object detection sensors 2-1 through 2-6 detecting the objects moving along the registered paths and the correct answer data.SELECTED DRAWING: Figure 6
