User guide for the USGS aerial camera Report of …
- https://www.usgs.gov/node/173863
- Calibration and testing of aerial mapping cameras includes the measurement of optical constants and the check for proper functioning of a number of complicated mechanical and electrical parts. For this purpose the US Geological Survey performs an operational type photographic calibration. This paper is not strictly a scientific paper but rather a 'user guide' to …
AERIAL CAMERA METRIC CALIBRATION – HISTORY …
- https://www.asprs.org/a/publications/proceedings/Sacramento2012/files/MERCHANT.pdf
- With the introduction of GPS spatial positioning of the airborne camera exposure station, the possibility of camera calibration based on operationally acquired photography became practical. This approach, usually referred to as an “in situ” approach to calibration, is in accord with the specifications for the calibration of measurement

- Your GPS showed a 115-knot ground speed when heading 360° and a 95-knot ground speed when heading 180°. You determine the wind is from the south at 10 knots by subtracting the maximum from the minimum ground speeds and dividing by 2. Applying this 10-knot wind correction to the GPS ground speeds, you determine your true airspeed was 105 …

- scene with GPS data. In this paper, we developed a constrained system for auto-calibration from aerial images and followed by a 3D camera pose estimation. We get images of a planar scene from different viewpoints with GPS data for each frame (Fig. 1). We used GPS position of the UAV as a constraint on the unknowns to suppress spurious solutions.
