- Abstract:
- Our aim is to establish a measurement system that enables highly accurate measuring mass and length of moving products with a relatively high speed on a conveyor belt. In this paper, effectiveness of the proposed measurement system is demonstrated by an analysis of a digital image taken by a digital camera. In our experimental results, it can be found in the following: First, our discrimination method of colors is that there is no need to count the number of pixels for all three primary colors, but the only one component indicated the highest value of graduation should be counted. Second, the length measurements are performed using these six kinds of the reference unit pixels for the products having lengths within a range from 200 to 1200 mm. It is quite obvious that even through any reference lengths used, the required accuracies less than ±5 mm cannot be achieved without calibration method.
