Abstract
An passenger conveyance system includes a depth-sensing sensor within a passenger conveyance enclosure for capturing depth map data of objects within a field of view that includes a passenger conveyance door. A processing module is in communication with the depth-sensing sensor to receive the depth map data, the processing module uses the depth map data to track an object and calculate passenger data associated with the tracked object. a passenger conveyance controller receives the passenger data from the processing module to control operation of a passenger conveyance door in response to the passenger data.
Claims26
A passenger conveyance system, comprising:
- a depth-sensing sensor for capturing 3D depth map data of objects within a field of view that comprises a passenger conveyance door and a waiting area adjacent to the passenger conveyance door;
- a processing module in communication with the depth-sensing sensor to receive the 3D depth map data, the processing module uses the 3D depth map data to track an object and calculate passenger data associated with the tracked object;
- and
- a passenger conveyance controller in communication with the processing module to receive the passenger data, the passenger data comprises an estimated arrival time and a number of passengers waiting for a passenger conveyance cab, to control a door dwell time of a passenger conveyance door in response to the passenger data.
A method of providing video aided data for use in passenger conveyance control, the method comprising:
- detecting an object located in an area adjacent to a passenger conveyance door;
- tracking the object based on distance to the passenger conveyance door;
- calculating passenger data associated with the tracked object, the passenger data comprises an estimated arrival time, and a number of passengers waiting for a passenger conveyance;
- and
- providing the passenger data to a passenger conveyance controller, wherein the passenger conveyance controller causes a passenger conveyance door to be controlled to control a door dwell time in response to the passenger data.
