Abstract
This paper describes a Vision Survey System, a tool for providing Product Definition Data for automatic manufacturing of large unique construction elements. The system uses multiple cameras to scan large workpieces. Scene interpretation and model-based image processing results in 3D-geometry data of the workpiece and its position and orientation in an absolute coordinate system. The achieved accuracy is satisfactory for the application, typically a robotic production environment. Here the Vision Survey System can be considered as a global (off-line) sensor to provide input data for initial robot trajectory generation, eliminating the burden of manually teaching the robot’s TCP paths. Local sensors are used (on-line) for fine-tuning of the robot movements.
The system development was funded by the EC within the 3rd Framework R & D programme in the field of Information Technologies. The ESPRIT Projects nr. 5369 HEPHAESTOS I and nr. 6042 HEPHAESTOS II were carried out with the objective of constructing an intelligent robot arc welding system for thick-steel unique fabrications, see ESPRIT (1992, 1995). The projects involved international research cooperation with partners from Greece, Spain, UK, France, Sweden and the Netherlands.
