Abstract

The present application relates to a calibration enclosure, systems that include a calibration enclosure, and methods of using the same. A calibration enclosure includes a body having an interior surface and one or more projections disposed at one or more locations on the interior surface of the body. Each one of the one or more projections provides an encoded signal that is usable for calibrating a vehicle sensor when the calibration enclosure is placed over a vehicle including the vehicle sensor such that the calibration enclosure covers the vehicle.

First claim

What is claimed is:

1. A calibration enclosure, comprising:
a body comprising an interior surface; and
one or more projections disposed at one or more locations on the interior surface of the body, each one of the one or more projections providing an encoded signal that is usable for calibrating a vehicle sensor when the calibration enclosure is placed over a vehicle comprising the vehicle sensor such that the calibration enclosure covers the vehicle.

2. The calibration enclosure of claim 1 , wherein at least one of one of the one or more projections is particularly positioned with respect to the vehicle sensor when the calibration enclosure is arranged with respect to the vehicle.

3. The calibration enclosure of claim 1 , wherein at least one of the one or more projections is a static projection.

4. The calibration enclosure of claim 1 , wherein at least one of the one or more projections is a dynamic projection.

5. The calibration enclosure of claim 4 , wherein the dynamic projection is communicatively coupled to the vehicle sensor such that one or more signals are transmitted by the vehicle sensor to cause the dynamic projection to change.

6. The calibration enclosure of claim 1 , wherein at least one of the one or more projections comprises a plurality of shapes arranged in a particular manner that is recognizable by a software algorithm for the purposes of calibration.

7. The calibration enclosure of claim 1 , wherein the body is constructed of a rigid material.

8. The calibration enclosure of claim 1 , wherein the body is constructed of a pliable material.

9. The calibration enclosure of claim 1 , wherein the body is shaped and sized to correspond to a shape and a size of a particular vehicle.

10. The calibration enclosure of claim 1 , wherein the body is shaped and sized to correspond to a shape and size of a particular class of vehicle.

11. The calibration enclosure of claim 1 , wherein the body is shaped and sized to correspond to a shape and size of a plurality of vehicle types.

12. The calibration enclosure of claim 1 , wherein the body defines a cavity that receives the vehicle when the calibration enclosure is placed over the vehicle.

13. The calibration enclosure of claim 1 , wherein the body further comprises one or more alignment features that provide an indicator of alignment with the vehicle when the calibration enclosure is placed over the vehicle.

14. A system for calibrating one or more vehicle sensors, the system comprising:
a calibration enclosure, the calibration enclosure comprising one or more projections disposed at one or more locations on the calibration enclosure, each one of the one or more projections providing an encoded signal that is usable for calibrating at least one of the one or more vehicle sensors when the calibration enclosure is placed over a vehicle comprising the one or more vehicle sensors such that the calibration enclosure covers the vehicle.

15. The system of claim 14 , wherein at least one of one of the one or more projections is particularly positioned with respect to at least one of the one or more vehicle sensors when the calibration enclosure is arranged with respect to the vehicle.

16. The system of claim 14 , wherein at least one of the one or more projections is a static projection.

17. The system of claim 14 , wherein at least one of the one or more projections is a dynamic projection.

18. The system of claim 17 , wherein the dynamic projection is communicatively coupled to at least one of the one or more vehicle sensors such that one or more signals are transmitted by the at least one vehicle sensor to cause the dynamic projection to change.

19. A method of calibrating at least one vehicle sensor disposed on a vehicle, the method comprising:
placing a calibration enclosure over the vehicle such that the calibration enclosure covers the vehicle, the calibration enclosure comprising an interior surface having one or more projections disposed at one or more locations on the interior surface, each one of the one or more projections providing an encoded signal that is usable for calibrating the at least one vehicle sensor; and
executing at least one calibration algorithm, the at least one calibration algorithm using data obtained from at least one of the one or more projections to calibrate the at least one vehicle sensor.

20. The method of claim 19 , further comprising:
aligning the calibration enclosure with the vehicle.
