Constructing hardwave to count number of steel bar in the steel bunches by image processing

In this paper, we propose a new algorithm that is used to exactly count number of steel bars in the bundles via their image of each bunch. We also bring out an initial experiment perform on hardware to realized this algorithm for speed up processing. On that way the device can standalone without PC. Experiments are implemented on the kit Altera DE2. The results proved the correctness of algorithm and solution. | Phạm Đức Long Tạp chí KHOA HỌC & CÔNG NGHỆ 181(05): 61- 66 CONSTRUCTING HARDWAVE TO COUNT NUMBER OF STEEL BAR IN THE STEEL BUNCHES BY IMAGE PROCESSING Pham Duc Long* University of Information and Communication Technology - TNU ABSTRACT In this paper, we propose a new algorithm that is used to exactly count number of steel bars in the bundles via their image of each bunch. We also bring out an initial experiment perform on hardware to realized this algorithm for speed up processing. On that way the device can standalone without PC. Experiments are implemented on the kit Altera DE2. The results proved the correctness of algorithm and solution. Keywords: count by image processing, count bar steel, image processing on the hardware THE REQUIRES FROM PRACTICE* Counting the number of steel bar in a steel bundle Currently, in Vietnam in the rough rolling mill for using in the construction haves usually two common products are rolled steel and steel bar. Steel bars from the factory are sold to major agents in units of weight (tons of cargo). But the small agents usually are selling with number of steel bar. In order to avoid being stolen during transportation and to close strengthen warehouse management, it is important to exactly count the number of steel bar per bunch corresponding to the weight of each bundle. Because the weight of each steel bar has toleran, therefore, it is impossible division the weight of the steel bundle by the weight of each steel bar to get the number of steel bar in the bundle. Counting by image processing program on the computer Counting in the production process: It is counting each steel bar in the last stage of process (called the product recall stage). When number of steel bar is enough then line is stopped to packing the steel bundle. Counting by infrared sensors is inaccurate, because affect of noise in the factory is very large (the amplitude of the noise can reach more than 100V). Some factories in Vietnam often use mechanical .
