Title:
物体検出センサ及び監視システム
Document Type and Number:
Japanese Patent JP6726043
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve a reliability level in determining a movement state on the basis of a gravity position of an object in an object detection sensor periodically scanning an object area by a range finder to detect the object.SOLUTION: A detection unit 22 is configured to measure a position of a detection point about an object, and a control unit 24 comprises: a monitor object detection unit that detects a cluster satisfying a preliminarily given condition of a cluster of the detection point as a monitor object corresponding to a detection purpose object; a representative position calculation unit that calculates a representative position of the monitor object; an identical object determination unit that determines a detection purpose object corresponding to the same detection purpose object between a past monitor object and a current monitor object; a state determination unit that makes a state determination of the detection purpose object on the basis of a change in representative position about the detection purpose object. The state determination unit is configured to, when a size of the current monitor object about the detection purpose object changes greater than a prescribed reference with respect to the past monitor object, maintain a previous state determination result as a current state determination result.SELECTED DRAWING: Figure 2
