Measurement system for contactless detection of the contour of long objects with diffuse reflecting surface.

摘要

The invention is provided in particular for use in sawmills, in order to cut sharp-edged boards from sidings. The aim is to use optoelectronic components to construct a measuring system which can be easily realised for long objects having a diffusely reflecting surface, it being permissible for the measuring system to require additional space for measurement. For this purpose, in order to detect the measurement object contours a plurality of radiation sources are mounted, at a specific measuring distance from one another which becomes larger from the reference point of the detector row, and parallel to the longitudinal axis of the measurement objects outside the observation plane of the evaluating detector row, so that as seen from the detector row a triangle is produced in their illuminating plane. The measurement object is guided at right angles to the observation plane, measuring points then recording the respective contour at this point per radiation source. IMAGE
