| Abstract: | Real-time Detection of colorless Liquid Level in Transparent Bottle can significantly improve the efficiency of product testing in the production line, while saving labor costs, which can effectively realize lean production and improve the added value. In this paper a method of real-time detection system based on OpenCV without the aid of external tools was reported. The image of product was captured through the camera, liquid region viewed from a series of pretreatments.Through calculating we can get the height of the bounding box which shows the liquid level.The results of experiment showed that the system has good stability and high accuracy. It can be effectively applied in practical engineering. |
