Quality control in 2D and 3D (TQC)
Vision systems for difficult environments with Firewire cameras and audio analysis. The system is used for inspection/quality control in roof tile production, both in 2D and 3D. The size of the tiles is checked, and defects in the surface and edges are detected by cameras, where micrometre-thin cracks are revealed. Additionally noise analysis is used for detecting hidden cracks inside the tile.
The software is written in C++ using DirectShow and Microsoft Visual Studio.
The hardware consists of a PC with I/O-cards and external PLC and photoelectric sensors, and is built with Bosch strut profiles around the conveyor belt.
The system is fully parameter-controlled and stores the statistics. The user can choose to save images and sound recordings for a follow-up. The system has a variety of custom variants delivered to the Swedish and Danish tileworks for different kinds of clay and concrete tiles.
