Abstract

A system includes one or more retro-reflective markers positioned within a ride system and a tracking system that may detect the one or more retro-reflective markers to track a position of a rider. The tracking system includes an emitter that may emit light toward the one or more retro-reflective markers, a detector that may detect reflected light from the one or more retro-reflective markers, and a controller that may determine the position of the rider relative to the one or more retro-reflective markers based on detection of the reflected light and that may provide an indication of the position of the rider.

Claims

1. A system comprising:

a plurality of retro-reflective markers positioned within an amusement park ride system;

a ride seat of the ride system having a support against which a rider can be restrained and having a restraint that is moveable relative to the support, wherein a first retro-reflective marker of the plurality of retro-reflective markers is positioned on the support and a second retro-reflective marker of the plurality of retro-reflective markers is positioned on the restraint;

a tracking system configured to detect the one or more plurality of retro-reflective markers to track a position of the restraint relative to the support, wherein the tracking system comprises;

an emitter configured to emit light toward the one or more plurality of retro-reflective markers;

a detector configured to detect reflected light from the one or more plurality of retro-reflective markers;

a controller configured to determine the position of the restraint relative to the support and to determine a status of the rider based on detection of one or more characteristics of the reflected light, and wherein the controller is configured to provide an indication of the position status of the rider, wherein the status of the rider is a size of the rider; and

wherein the controller is configured to adjust an operational parameter of the amusement park ride system based on the position of the restraint, the status of the rider, or both.

2. The system of claim 1, wherein the controller is configured to actuate an audible or visual alert via an interface communicatively coupled to the controller based on the position of the restraint, the status of the rider, or both.

3. The system of claim 1, wherein the controller is configured to determine the position of the restraint based on a change in reflected light intensity from at least one of the plurality of retro-reflective markers.

4. The system of claim 1, wherein the controller is configured to associate a decrease in the reflected light intensity with the size of the rider.

5. The system of claim 1, wherein the first retro-reflective marker is part of an array of retro-reflective markers that are disposed on a lumbar region of the support, a headrest of the support or any combination thereof, and the controller is configured to determine the size of the rider based on a pattern of the array of retro-reflective markers detected by the controller.

6. The system of claim 1, wherein the first retro-reflective marker is disposed on a headrest of the support and configured to determine a height of the rider.

7. The system of claim 1, wherein the controller is configured to determine the size of the rider based on the position of the restraint relative to the support.

8. The system of claim 1, wherein the restraint is configured to be actuated to a position in which the restraint is able to maintain the rider in the ride seat.

9. The system of claim 8, wherein the first retro-reflective marker is configured to reflect light at a first wavelength and the second retro-reflective marker is configured to reflect light at a second wavelength different from the first wavelength, and wherein the controller is configured to distinguish between the light reflected by the first and second retro-reflective markers to evaluate ridership and the position of the restraint.

10. A method comprising:

emitting electromagnetic radiation from an emitter toward a plurality of retro-reflective markers disposed in a ride system of an amusement park ride, wherein the emitter is a part of a tracking system configured to track the one or more retro-reflective markers, wherein the ride system comprises a ride seat having a support against which a rider can be restrained and having a restraint that is movable relative to the support, and wherein a first retro-reflective marker of the plurality of retro-reflective markers is positioned on the support and a second retro-reflective maker of the plurality of retro-reflective markers is positioned on the restraint;

reflecting the electromagnetic radiation from the plurality of retro-reflective markers;

detecting the reflected electromagnetic radiation with a detector of the tracking system;

determining a position of the restraint relative to the support and a status of the rider based on one or more characteristics of the reflected electromagnetic radiation using a controller communicatively coupled to the tracking system;

providing, using the controller, an indication of the status of the rider based on the one or more characteristics of the reflected electromagnetic radiation, wherein the status is a size of the rider; and

adjusting an operational parameter of the amusement park ride based on the position of the restraint, the status of the rider, or both.

11. The method of claim 10, comprising determining a change in intensity of the reflected electromagnetic radiation using the controller, wherein the change in intensity is correlated with the position of the restraint relative to the support, the status of the rider, or both.

12. The method of claim 10, comprising detecting a pattern of multiple retro-reflective markers of a known array of retro-reflective markers, wherein the first retro-reflective marker, the second retro-reflective marker, or both, are part of the known array of retro-reflective markers, and wherein the pattern is indicative of the position of the restraint, the size of the rider restrained in the ride seat, or both.

13. The method of claim 12, wherein the pattern is based on fewer than all of the retro-reflective markers in the known array.

14. The method of claim 10, comprising displaying an alert indicating the position of the restraint, the status of the rider, or both.

15. The method of claim 10, comprising actuating a device in response to determining the position of the restraint, the status of the rider, or both, wherein the device is communicatively coupled to the amusement park ride.

16. A system, comprising:

a controller, comprising;

one or more tangible, non-transitory, machine-readable media collectively storing one or more sets of instructions; and

one or more processing devices configured to execute the one or more sets of instructions to;

activate an emitter, wherein the emitter emits electromagnetic radiation towards a plurality of retro-reflective markers disposed on an amusement park ride, wherein the amusement park ride comprises a ride seat having a support against which a rider can be restrained and having a restraint that is movable relative to the support, wherein a first retro-reflective marker of the plurality of retro-reflective markers is positioned on the support and a second retro-reflective marker of the plurality of retro-reflective markers is positioned on the restraint;

receive detected electromagnetic radiation reflected from all or a portion of the plurality of retro-reflective markers via a detector;

determine a position of the restraint relative to the support and a status of the rider positioned in the ride seat based on the detected electromagnetic radiation, wherein the status of the rider is a size of the rider; and

actuate a device in response to the position of the restraint, the status of the rider, or both, wherein the device is configured to adjust an operational parameter of the amusement park ride.

17. The system of claim 16, wherein the controller is a part of a dynamic signal to noise ratio tracking system.

18. The system of claim 16, wherein the controller is configured to determine the size of the rider based on the position of the restraint.

19. The system of claim 18, wherein the first retro-reflective marker is disposed on a lumbar region of the support or a headrest of the support.

20. The system of claim 16, wherein the one or more processing devices are configured to execute the one or more sets of instructions to determine a height of the rider based on a change in intensity of the reflected electromagnetic radiation from the first retro-reflective marker.
