	Quarry Leitendorf

	This case study shows how different imaging techniques can work together. A 3D Overview image of the quarry was generated using very high resolution images from the JMX PanoramaScanner. The unfavourable imaging geometry and the quarry benches caused that areas of interest remained in occluded regions. Thus 3D detail images using a conventional digital camera (calibrated) were taken from the desired levels closely to the rock face. The 3D detail images were referenced to the 3D overview image using corresponding points from nature (no markers) which means that all measurements taken from the 3D detail images can be used together with the measurements from the 3D overview image. Of course 3D detail images originating from the JMX PanoramaScanner can also be referenced that way.


	3D overview image with about 50 megapixel; image resolution is about 3 cm / pixel; imaging distance: ~100 m. The green area indicates a possible 3D detail image based on the JMX PanoramaScanner (image resolution: ~ 0,4 cm / pixel). The blue spots show regions acquired with a conventional calibrated digital camera.


	3D detail image of about 100 m² taken with a conventional camera; image resolution is about 0,6 cm / pixel; imaging distance: ~ 10 m ; the dashed yellow line corresponds to 1 m.
