We continue with a series of posts about Protostar Vision Box. This article explains our approach to the bottle cap color recognition problem in a real industrial application. The solution to this problem is important because of stray caps of the wrong color during production, which need to be separated from bottles with the correct cap color. This solution must be robust and precise as well as light and fast, since cap color recognition is just one of many other inspections that need to be performed on every bottle that arrives on the conveyor belt.
