MONITORING DEVICE AND MONITORING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a monitoring device capable of detecting an object to be selected in terms of protecting a protective object among objects approaching the protective object, and monitoring it.SOLUTION: A monitoring device 10 includes: a three-dimensional light measurement unit 11 measuring a three-dimensional coordinate in a visual field V facing a protective object P; a monitoring region setting unit 21 setting a monitoring area Aw with the three-dimensional coordinate of the protective object P measured by the three-dimensional light measurement unit 11 as reference; a shape detection unit 22 detecting that a specific object Os having a set specific shape exists in the monitoring area Aw, on the basis of the three-dimensional coordinate measured by the three-dimensional light measurement unit 11; and a monitoring state determination unit 23 determining the state of the monitoring area Aw on the basis of the detection result in the shape detection unit 22.SELECTED DRAWING: Figure 1
