A lot of activities on a dairy farm can be automated such as milking and feeding. But can we also automate body weight measuring, and how accurate is it? Researchers in the Netherlands looked into this using a 3-D vision system. Recent developments in sensor technology offer promising solutions to automate health monitoring by collecting daily information on the physical status of individual cows. An example of health monitoring includes monitoring of the body weight (BW) of dairy cows. And for
