There is a perception that digital frame cameras produce imagery in much the same way as traditional analog frame cameras. Therefore, it was sometimes thought that the transition from analog photogrammetric processing to digital frame camera workflow would be easy and smooth, while the adaptation to line sensor workflow would involve significant relearning. Recent reports from customers using both frame and line sensor workflow are proof that these perceptions are wrong!
Large-format frame sensor configurations use multiple sensor heads. To produce a final frame requires several additional processing steps which include compensation of system specific parameters, co-registration of the multiple head patched data and the introduction of so-called "virtual frames".
In comparison, the Leica XPro line sensor workflow is straightforward to implement and easy to use for those familiar with the traditional analog frame processing. Most importantly, it produces the best results.
Performance Indicators:
1. Manage data quality
- Quality control tools can indicate a successful data capture mission at the earliest stage of processing
- Uniform workflow from download to orthophoto generation
2. Add accuracy
- Direct georeferencing from Leica IPAS Inertial Position & Attitude System is used and further improved by aerial triangulation
- Aerial triangulation step of Leica XPro is simplified to a "black box" level
- Deliver at the speed of flight
- For stereoviewable images or high resolution orthophotos – Leica XPro is designed to deliver with extreme speed
- Products are ready for further handling by a wide range of digital photogrammetry software packages

Going for gold
Since its release in December 2010 XPro DSM has proven itself as a valuable tool for ortho production, city modeling or in application specific image processing, such as the mining industry.
