Abstract: A portable sensor calibration target includes a frame assembly, a first panel, and a second panel. The frame assembly may include three legs and a plurality of frame edges that is configured to form a first frame and a second frame and is configured to be held at a pre-selected height above ground by the legs. The first panel is removably attached to the first frame in an unfolded position, and includes a plurality of boards and a plurality of hinges connecting the plurality of boards. The first panel is configured to fold at the plurality of hinges into a folded position. The second panel is removably attached to the second frame adjacent to the first frame. The first panel and the second panel meet to form an edge, which is detectable by a detection system of a vehicle for calibrating the detection system.
