[VI-478] Study on development of crack width measurement device of concrete structure surface using smartphone and camera
Keywords:Crack width, Crack scale
In maintenance of concrete structures,crack inspection is a material that provides important information to determine the need for detailed investigations such as investigating internal damage conditions .Measurement of crack width is a very important measurement index to estimate the durability and the cause of deterioration of a structure.This time,we developed a crack width measurement device that can easily measure the crack width on the spot and reduce the measurement error caused by people.
