VERFAHREN UND VORRICHTUNG ZUM VERMESSEN VON KONTUREN

A measurement wheel rolls over contours while its rotation is recorded by a motion sensor and its changes of direction are recorded by a direction sensor. The thus sensed rotation and changes of direction are supplied to a computer to be processed and stored. The direction and the absolute distance covered by the measurement wheel in the plane may be continuously determined from its rotation and simultaneously sensed changes of direction. Contours in a three-dimensional space may be recorded by means of an additional inclination sensor. The contours covered by the measurement wheel may thus be viewed true to scale on the monitor of a computer and further processed. This measurement device is particularly useful to considerably reduce the time needed to measure road courses and accident sites.
