Optical 3D scanning accuracy check

Abstract

Opisano cztery metody optycznego skanowania 3D: wiązką lasera, widzialnym i podczerwonym światłem strukturalnym oraz fotogrametrią. Wyniki pomiarów porównano z pomiarem referencyjnym i przedstawiono w postaci map odchyłek. SŁOWA KLUCZOWE: skaner 3D, pomiar, odchyłkiThe article describes four different methods of optical 3D scanning: laser beam, visible/infrared structural light and photogrammetry methods. The measurement results were compared with the reference measurements and shown in the deviation maps.

Application of optical scanning system to determine the machining allowances

“…-non-contact measurement -the casting can be partially dirty or oiled without the hazard of damaging the measurement device, -possibility of collecting even as many as 4 million points as result of one measurement [20], -high quantity of data collected at a time reduces the time of operation, -possibility of automating the measurement -no need to have a trained employee to perform the measurement, -precision of measurement by an order better than in the case of tracing [20][21][22] measurement tolerance lower than actually necessary. …”
