エレベータ乗車行動判定装置における外光対策

抄録

A conventional system based on a photoelectric sensor could prevent that an elevator door hits against the passenger. The system can make the door reverse from closing direction when it detects the passenger. However, the system has some problems such as the detection area is narrow. In order to solve the problem, a new system constructed with a camera and image analysis algorithm has been developed. But, the new system has a problem of misjudging the elevator door as a passenger while it is affected by ambient light. In this study, a measure to discriminate between the door and the passenger is established.
