AR4CAD – Augmented Reality for industrial applications

AR4CAD is a research project at T3LAB, where AR technology is investigated for industrial applications: in particular, it has been applied to improve assembly works. The operator is guided by multi-media instructions (text, audio, animations, movies, …) and virtual objects that are displayed where the corresponding real object should be mounted. Currently the operator sees the augmented view in a window of a normal PC screen together with other windows displaying additional, related information. Interactions between the operator and the AR system are mostly voice based. Virtual objects are created from CAD descriptions. CAD tools are also used to describe the assembly storyboard, based on the exploded view of the assembly and adding specific pragmas to image frames. Recognition, localization and tracking of real objects are performed without markers and using a normal machine vision library. Virtual object images, animations and models for object recognitions are automatically generated from the assembly storyboard.
