<p>A teatcup liner for a teatcup has a longitudinal shape extending along a longitudinal axis (x). The teatcup liner comprises a barrel (2) having a length (L) and defining an inner space (21) for receiving the teat. The barrel has a polygonal cross-sectional shape transversely to the longitudinal axis along the barrel. The polygonal cross-sectional shape defines a plurality of corner portions (23) and a plurality of side portions (24), each connecting two of said corner portions (23). Each corner portion (23) comprises an inner surface (25)facing the inner space (21) and having an inner radius (r) extending from the inner space (21) to the inner surface (25). The inner radius (r) is equal for each corner portion (23). Furthermore, the inner radius (r) of each of the corner portions (23) is at least 4 mm at a centre part of the corner portion (23).

A vision system (10) for a motor vehicle comprises an imaging means (11) with a plurality of imaging devices (12.1, 12.2) for acquiring images from a surrounding of a motor vehicle, and a processing means (14) adapted to perform image processing on images from said imaging devices (12.1, 12.2). The processing means comprises an object detection means (20) adapted to detect objects in the surrounding of the motor vehicle based on image data from said imaging means (11), and a calibration means (21) adapted to estimate the extrinsic calibration of at least one of said imaging devices (12.1, 12.2). The calibration means(21) is adapted to perform said estimation using the position of detected objects provided by said object detection means (20).</p> |
