VEHICULAR PRISMATIC INTERIOR REARVIEW MIRROR ASSEMBLY WITH DRIVER MONITORING CAMERA

A vehicular interior rearview mirror assembly includes a mirror head adjustably attached at a mounting base. The mirror head includes a prismatic mirror reflective element having a wedge-shaped, reflector-coated glass substrate having a front side and a rear side separated by a thickness of the glass substrate, with the thickness of the glass substrate varying between a lower edge region of the glass substrate and an upper edge region of the glass substrate. A driver monitoring camera is accommodated by the mirror head and views through the prismatic mirror reflective element. A refraction-compensating element is disposed between a lens of the driver monitoring camera and the rear side of the glass substrate of the prismatic mirror reflective element. The refraction-compensating element is a wedge-shaped element that offsets refraction of light that passes through the wedge-shaped, reflector coated glass substrate of the prismatic mirror reflective element.

A method detects a suspension position of a supporting bar in a pallet, having supporting bars along a longitudinal direction, each with multiple supporting bar tips along a main direction of extent. The supporting bar tips define a supporting plane. A two-dimensional contrast-image dataset of the pallet is created, its pixels being assigned a pixel value and a pixel-area unit of the supporting plane. The contrast-image dataset has regions that are assigned to the supporting bar tips as local pixel-value extremes in a uniform pixel-value background. A longitudinal position is determined in the contrast-image dataset of the regions that are assigned to the supporting bar tips a supporting bar using the local pixel-value extremes. The suspension position of the supporting bar in the pallet is deduced based on the longitudinal position in the contrast-image dataset and an extent of the pixel-area unit in the longitudinal direction.
