Length measurement of moving products on conveyor belt (2nd report)

The goal of our study is to present an entirely new method which achieves higher speed of operation and highly accurate length measurement of products on a conveyor belt. We propose to measure the length of products with a digital image taken by a digital camera. We discuss some technical problems to estimate the length of products with high accuracy. In this paper, we demonstrate the length established by using 4 kinds of the calibration formulas from data obtained. As the result, the length measurement of all products by using the calibration formula derived from data of the 4th row can be satisfied with the required accuracy.
