The invention provides a rear spoiler which is capable of suppressing an increase in air resistance and applying a downforce to a vehicular rear portion during high-speed vehicle traveling. The rear spoiler (1) on the rear upside of a vehicle includes a main body (2) that is longer in a longitudinal direction than in a width direction. The main body (2) includes an air introduction opening (14) of air currents, and a wing (3) and an air outlet (17) communicating with the opening (14) at the rear.

Further, the main body (2) is arranged in the vehicular lateral side and hence by rectifying the vortex flows generated by the air currents coming around the vehicular lateral side, the air resistance is restrained from increasing during high-speed traveling, permitting the travel resistance to be reduced.

In this invention, systems and methods are described that allow performing stereo reconstruction with line-scan cameras in general configurations. Consequently, the cumbersome exact alignment of the sensor lines becomes superfluous. The proposed method requires that telecentric lenses instead of perspective lenses are mounted on the line-scan cameras. In this case, the images can be accurately rectified with stereo rectification. The rectified images can be used to perform an efficient stereo matching. The method comprises a camera model and a calibration procedure that allow to precisely model the imaging process, also including the modelling of lens distortions even if the sensor lines are not exactly mounted behind the principal points. This ensures a high accuracy of the resulting 3D reconstruction.
