The parts of the ship's structure and machinery are determined according to the conditions of use under different environmental conditions. Ship structures and machinery parts have a wide range of properties, such as mechanical properties. Properties relationship between stress and strain chemical properties and other properties which mechanical properties such as hardness (Hardness) and toughness (Strength) are important components of ship structures and machinery. In particular, the grain size of the metal structure greatly affects the mechanical properties of the metal. At present, structural analysis and testing can be performed manually to verify the properties, but it is time consuming and time consuming to verify. Thus, an idea was born to create a prototype automatic grain size measurement program for metals and alloys by means of digital image processing. To reduce the measurement error that has occurred due to the error of the meter, save time, save resources and increase the speed of inspection.
