In order to reduce the cost of breeding in pig farms, it is necessary to control pig weight through regular growth monitoring and controlling the feed supply. However, it is not easy to measure the weight of pigs due to the difficulty involved with placing a pig on a scale. We propose a weight measurement method based on image processing as part of a smart-farm for the easy management of pigs in rural areas. To this end, we take a picture of a pig with a checker board marker on it. The pig’s weight is then calculated using a regression equation with the measured girth. The weight shows errors within only 3.8%, which is acceptable for the purpose of farmers.
