Abstract

In this study, an algorithm was developed to measure the volume of meat products passing through the conveyor line of a portion cutter using a stereo vision sensor and calculate the cutting position to cut them into the same weight unit. Previously, three or more laser profile sensors were used for this purpose. However, in this study, the volume was measured using four stereo vision sensors, and the accuracy of the developed algorithm was verified to confirm the applicability of the technique. The technique consists of stereo correction, scanning and outlier removal, and cutting position calculation procedures. The comparison between the volume measured using the developed algorithm and the results measured using an accurate 3D scanner confirmed an accuracy of 91%. Additionally, in the case of 50g target weight, where the cutting position calculation is crucial, the cutting position was calculated at a speed of about 2.98 seconds, further confirming the applicability of the developed technique.
