Surface contour detector in three=dimensional space - has two measurement wheels and supporting wheel defining plane, measurement wheel rotation sensors and inclination sensor

摘要

The device has two measurement wheels (4) with parallel rotation axes and a supporting wheel (9). All three wheels are moved over the surface and turn independently of each other. They define a plane. The rotation angles of the measurement wheels are measured digitially and independently of each other. The inclination of the plane defined by the three wheels w.r.t. the horizontal is measured by an inclination sensor. The measurement wheels and inclination sensor are connected to a measurement device. The measuring wheels and inclination sensor are connected with a detector which comprises a microprocessor, a display (7) and a data interface. ADVANTAGE - Enables contours on surfaces to be measured in 3-dimensional space. Quick and accurate digitisation.
