Here we provide the missing link between industrial drawings and digital images of industrial sites. On one hand, this could enable us to calibrate the cameras and build the 3D model of the scene without using any calibration markers. On the other hand it brings industrial drawings, floor map, images and 3D models into one unified framework. This provides a solid foundation for building efficient enhanced virtual industrial environments. The augmented scene is obtained by perspective warping of an industrial drawing of the factory onto its floor, wherever floor is visible.
Experimental results illustrate the approach.
