An image based measurement system for the online inspection of electromechanical parts is described. The system uses two cameras to perform dimensional measurements and operates online. After the description of the measurement system and of its installation on the production line, the paper details the algorithms for the localization and the measurement of the required quantities, the calibration...
Based on the BS EN167 standard, it usually needed two operators to perform the prismatic refractive power measuring because the distance between tested eye-protector and image plane is about 2m. Furthermore, the prismatic refractive power measuring instruments were usually performed by using human eyes and the larger uncertainty of measurement will be induced while observing the measuring patterns...
Purification of waste water is commonly done using the activated sludge process. The ratio of the activated sludge flocs and filamentous bacteria play a key role in the purification process of waste water. The sludge bulking or filamentous bulking is a common problem in activated sludge plants that prevents flocs to settle down. Digital imaging techniques can play an important role in monitoring activated...
