摘要： The twist of a railway track (36) can be measured with a vehicle which includes a frame (25). This frame (25) carries a roll sensor (40) to measure the rate of roll (w) about a longitudinal axis, and sensors (38) to monitor the variations in the relative tilt between the frame (25) and the rails (35). The signals from these sensors (38) and (40) enable the changes in cant (Δc) between one instant and the next to be determined, and so the twist of the track can be calculated by summing successive changes in cant. This method of determining twist can operate at substantially any vehicle speed, and gives consistent measurements in real-time.

摘要： A profile of a surface of an object (12) that has a longitudinal axis is determined by arranging a camera (14) to view a portion of the surface with its viewing axis (15) substantially perpendicular to the longitudinal axis, and arranging two scanning light sources (16, 18) to define planes of illumination which define two lines on the surface, so that the camera produces an image including images of the two lines. From the separation of the two lines in the image the surface profile can be determined. The planes of illumination are preferably inclined to one another, as this can enhance sensitivity.
