The Oblique Imaging System OIS-M is a combined system for precise mapping and 3D modelling.
The OIS-M integrates 4 Canon 5DSR (4*50 MPIX) cameras equipped with Zeiss Milvus 1.4/85 mm lenses for the oblique views and a Phase One iXM-100 metric camera with a 50 mm lens for nadir image capturing that is used for precise mapping.
The OIS smart shooter software controls image exposure and storage procedures on all oblique cameras enabling a capture rate of 0.9 fps. The Phase One camera is controlled by iX Capture simultaneously.
The cameras are mounted extremely closely to provide low vignetting by the camera hatch. All components are designed for high-accuracy mapping. The cameras’ tilt angles can be modified between 30 and 45 degrees. The complete system is delivered with a calibration certificate. The system is defined as metric and the nadir data can be easily used for any surveying project.
All components are designed for mapping in high resolution up to 2 cm GSD, in oblique missions up to 5 cm GSD. The cameras’ tilt angles can be modified between 30 and 50 degrees. The complete system is delivered with a calibration certificate. The system is defined as fully metric for mapping and semi metric due to the focal plane shutter of the Canon cameras in oblique.
OIS-M makes use of our patented MCC device to guarantee a desynchronized event-based registration of the exposure centers with any of our GNSS-INS devices. For writing Exif information we use or new AeroCamTag to store GPS and time inside the imagefiles for all cameras.
The AeroStab-XL gyro stabilized mount is able to host the OIS-M. Our AeroTopoL FMS is perfectly designed for this camera setup and combined with our AeroDiDOS GNSS-INS to generate directly referenced data for a smooth workflow.
What you get is a highly reasonable, accurate mapping system for generating 3D city models, for surveillance, web applications and simulation activities!
