Abstract
A video-based system detects the position of elevator doors based on video data provided by one or more video detectors. Based on the detected position of the elevator doors, a distance between the elevator doors can be determined. The operation of the elevator doors is controlled based, at least in part, on the detected distance between the elevator doors.
