Photogrammetry based system for the measurement of cylindrical forgings axis straightness

Popis výsledku v původním jazyce

This paper presents an approach to the axis straightness measurement of cylindrical forgings and shows results of the first experimental measurement in laboratory conditions. The proposed image-based system is based on the assumption that actual shape ofthe cylindrical forging axis can be determined (in the simplest case) from four boundary curves which lie in two mutually perpendicular planes. Four boundary curves can be obtained by detecting forging edges in two images. The measurement approach was tested in laboratory conditions on the cylindrical rod sample of room temperatures with length of 700 mm and diameter of 45 mm. Results of image-based measurement ware compared with results of measurement by industrial 3D scanner Atos III Triple Scan. Inthe case of maximum deflection size, the difference between both measurement methods is less than 0.3 mm; in the case of angle of maximal deflection is less than 3 degrees. Despite the positive forecasts, additional measurements must be p
