Real-Time Quantitative Ultrasonic Inspection
Most frequently applied ultrasonic inspection techniques measure the reflectivity of geometric scatterers that are caused by impurities, flaws and defects in the material. Based on the echo sounder principles, the reflector has to be insonified by directed sound pulses. This requires a large number of transducers with different incident angles and sound field patterns, which are more and more r...
متن کاملReal Time Inspection of Hidden Worlds
Smart Things” are commonly understood as wireless ad-hoc networked, mobile, autonomous, special purpose computing appliances, usually interacting with their environment implicitly via a variety of sensors on the input side and actuators on the output side. Such smart appliances have started to populate the “real world” with “hidden” or “invisible” services, thus building up an “invisible world”...
متن کاملReal-time surface inspection by texture
In this paper a real-time surface inspection method based on texture features is introduced. The proposed approach is based on the Local Binary Pattern (LBP) texture operator and the Self-Organizing Map (SOM). A very fast software implementation of the LBP operator is presented. The SOM is used as a powerful classifier and visualizer. The efficiency of the method is empirically evaluated in two...
متن کاملThe Intelligent Inspection Engine { A Real - Time Real - World
| An Intelligent Inspection Engine (IIE) for classiication of non-regular shaped objects from images is described and evaluated using real-world data from a waste package sorting application. The entire system is self-organizing. Principal component analysis and additional a priori knowledge on color properties are used for feature extraction. As classiiers growing neural networks provide robus...
متن کاملViSyR: a Vision System for Real-Time Infrastructure Inspection
The railway maintenance is a particular application context in which the periodical surface inspection of the rolling plane is required in order to prevent any dangerous situation. Usually, this task is performed by trained personnel that, periodically, walks along the railway network searching for visual anomalies. Actually, this manual inspection is slow, laborious and potentially hazardous, ...
