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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 1) The calibration enclosure of claim 1, wherein at least one of the one or more projections is a static projection. ### Claim 4 (depends on 1) The calibration enclosure of claim 1, wherein at least one of the one or more projections is a dynamic projection. ### Claim 5 (depends on 4) 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. ### Claim 6 (depends on 1) 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. ### Claim 7 (depends on 1) The calibration enclosure of claim 1, wherein the body is constructed of a rigid material. ### Claim 8 (depends on 1) The calibration enclosure of claim 1, wherein the body is constructed of a pliable material. ### Claim 9 (depends on 1) 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. ### Claim 10 (depends on 1) 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. ### Claim 11 (depends on 1) 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. ### Claim 12 (depends on 1) 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. ### Claim 13 (depends on 1) 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. ### Claim 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. ### Claim 15 (depends on 14) 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. ### Claim 16 (depends on 14) The system of claim 14, wherein at least one of the one or more projections is a static projection. ### Claim 17 (depends on 14) The system of claim 14, wherein at least one of the one or more projections is a dynamic projection. ### Claim 18 (depends on 17) 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. ### Claim 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. ### Claim 20 (depends on 19) The method of claim 19, further comprising: aligning the calibration enclosure with the vehicle.
