This paper presents a system of computer vision designed to be used in industry for product classification. The system is based on the TensorFlow and Keras software libraries and the Python programming language. In the production process, uniform cylindrical parts reach the conveyor designed so that each part can be in one of two possible positions. The computer vision system detects the exact position of the part, or its orientation, and this information is further used during the transportation process. The purpose of the procedure is for all parts to take the same orientation in relation to the production line.
