Abstract
A passenger conveyance system includes a depth-sensing sensor for capturing depth map data of objects within a field of view adjacent a passenger conveyance door. A processing module 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, and a passenger conveyance controller to receive the passenger data from the processing module, wherein the passenger conveyance controller controls a passenger conveyance dispatch control function in response to the passenger data.
Claims23
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 waiting area adjacent to a passenger conveyance cab door;
- a processing module in operable communication with the depth-sensing sensor to receive the 3D depth map data, the processing module using the 3D depth map data to track an object, determine an object parameter of the tracked 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, wherein the passenger conveyance controller controls a passenger conveyance dispatch control function in response to the passenger data to assign a passenger conveyance cab with appropriate free space.
A method of providing video aided data for use in passenger conveyance control, the method comprising:
- detecting an object located in a field of view of a depth-sensing sensor wherein the field of view comprises a passenger waiting area adjacent to a passenger conveyance cab 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;
- communicating the passenger data to a passenger conveyance controller;
- and
- controlling a passenger conveyance cab with the passenger conveyance controller in response to the passenger data to assign a passenger conveyance with appropriate free space.
