A set-up tool for aiding vehicle sensor calibrations having a structure with a first and second vehicle contact points configured to contact a vehicle and establish a calibration axis. A substantially vertically projected flat blade laser may be placed in a position perpendicular to the calibration axis and used to align the set-up tool with a center of the vehicle. Once centered, the laser ma be transitioned to project a laser line, in coordination with a protractor having a base-line parallel to the calibration axis (which is now substantially parallel to a transverse axis of the vehicle), at a discreet angle away from the center of the vehicle. A target may then be placed along the laser line to aid in the calibration of vehicle sensors.

Sensor calibration set-up tool with angular offset functionality

The apparatus comprises a target structure () having a reflective surface () and a crossbar structure oriented parallel to an axel of the vehicle; a first reference structure () having a pass-through channel () and an aiming surface (); a second reference structure () having a laser emitter (). In the method the first reference structure is aligned with a midpoint of a side of the vehicle nearest to the target structure and the second reference structure with the laser emitter is aligned with a midpoint of a side of the vehicle furthest from the target structure with the laser emitter oriented toward the target structure. The emitted laser beam passes through the channel of the first reference structure and is reflected by the reflective surface. The relative angle and alignment of the target structure at the reflection position is adjusted such that the reflected beam is reflected onto a designated region of the aiming surface on the first structure. The laser measurement may be in the form of a line generator to provide visual aid to the user in alignment.

Assisted portable vehicle sensor calibration alignment

An apparatus for calibration of vehicle sensors comprising a target structure and an alignment structure. The target structure comprises a portable arrangement, including a number of folding legs configurable into at least a first position. The target structure is further operable to be reconfigured to accommodate a variety of vehicles having different sensor placements.
