OBJECT MONITORING SYSTEM INCLUDING DISTANCE MEASURING DEVICE
First Claim
1. An object monitoring system including a distance measuring device configured to output a distance measurement value of a target space based on a phase difference between reference light emitted toward the target space and reflected light from the target space, wherein the system carries out determination of whether or net a monitored object, is present in a monitoring area set in the target space based on the distance measurement value, the system comprising:
- means for calculating an arrangement of an external object outside the monitoring area in the target space based on the distance measurement value of the external object, and estimating a shift amount of the distance measurement value caused by the external object in accordance with the calculated arrangement, andmeans for correcting the determination based on the estimated shift amount.
