3. The passenger conveyance passenger tracking control system of claim 2 , wherein the passenger conveyance control module cancels the passenger conveyance call request in response to the at least one passenger existing outside the at least one occupancy depth grid for a predetermined time period.

4. The passenger conveyance passenger tracking control system of claim 3 , wherein the passenger conveyance control module is configured to recognize a plurality of passengers located in at least one of the first occupancy depth grid and the second occupancy depth grid, and is configured to assign at least one of a passenger conveyance call request to a passenger among the plurality of passengers, a plurality of possible direct call requests to a passenger among the plurality of passengers, and an indirect call request to a passenger among the plurality of passengers that indicates a passenger's request is ambiguous as to the desired floor of the passenger.

5. The passenger conveyance passenger tracking control system of claim 4 , wherein the passenger conveyance control module cancels a passenger conveyance call request based on a first position of the first passenger and a second position of a second passenger among the plurality of passengers, the first and second positions compared to the second occupancy depth grid.

6. The passenger conveyance of claim 1 , wherein the passenger conveyance is an elevator.

7. A method of controlling at least one passenger conveyance, the method comprising:

determining at least one passenger conveyance call request input by at least one passenger located in at least one occupancy depth grid via at least one call request device; tracking a position of the at least one passenger with respect to the at least one occupancy depth grid; and

controlling operation of the passenger conveyance based on the position of the at least one passenger with respect to the at least one occupancy depth grid,

receiving an electronic data signal from the at least one passenger 3-D depth-sensing sensor identifying the position of the at least one passenger and the location of the at least one occupancy depth grid, and controlling operation of the passenger conveyance based on the position of the at least one passenger with respect to the at least one occupancy depth grid; and

monitoring a first occupancy depth grid located externally from a passenger conveyance system and monitoring a second occupancy depth grid located within the passenger conveyance, handing off at least one data monitored by a first 3-D depth-sensing sensor to a second 3-D depth-sensing sensor when at least one passenger moves from the first occupancy depth grid to the second occupancy depth grid, and data monitored by the second 3-D depth-sensing sensor to the first 3-D depth-sensing sensor when at least one passenger moves from the second occupancy depth grid to the first occupancy depth grid.

8. The method of claim 7 , further comprising cancelling an passenger conveyance call request based on at least one of the position of the at least one passenger with respect to the at least one occupancy depth grid, and the time period at which the at least one passenger enters a plurality of call requests.

9. The method of claim 8 , further comprising: determining a time period at which the at least one passenger is outside the at least one occupancy depth grid, and cancelling the passenger conveyance call request in response to the time period exceeding a time period threshold; and

recognizing a plurality of passengers located in at least one of the first occupancy depth grid and the second occupancy depth grid, and assigning at least one of a passenger conveyance call request to a passenger among the plurality of passengers, a plurality of possible call requests to a passenger among the plurality of passengers, and an indirect call request to a passenger among the plurality of passengers that indicates a passenger's request is ambiguous as to the desired floor of the passenger.

10. The method of claim 9 , further comprising:

determining a first position of the first passenger with respect to the second occupancy depth grid;

determining a second position of a second passenger among the plurality of passenger with respect to the second occupancy depth grid; and

cancelling an passenger conveyance request based on a comparison between the first and second positions, and the second occupancy depth grid.

11. A passenger conveyance passenger tracking control system that controls operation of a passenger conveyance, comprising:

at least one call request device configured to receive at least one input from at least one passenger located at a occupancy depth grid;

at least one passenger position three-dimensional (3-D) depth-sensing sensor configured to track a position of the at least one passenger located at the occupancy depth grid; and

an electronic control module in signal communication with the at least one call request device and the at least one passenger position 3-D depth-sensing sensor, the electronic control module configured to control operation of the passenger conveyance based on the position of the at least one passenger,

wherein the electronic control module receives monitors a first occupancy depth grid located externally from a passenger conveyance system based on a first output signal generated by a first position three-dimensional (3-D) depth-sensing sensor among the at one passenger position three-dimensional (3-D) depth-sensing sensor, monitors a second occupancy depth grid located within the passenger conveyance based on a second output signal generated by a second position three-dimensional (3-D) depth-sensing sensor among the at one passenger position three-dimensional (3-D) depth-sensing sensor, and
