Camera Calibration Geometrical Accuracy Variance Component Estimation UAV System Evaluation
2014/12/4
Camera calibration plays a more and more important role in recent times. Beside real digital aerial survey cameras the photogrammetric market is dominated by a big number of non-metric digital cameras...
A novel camera calibration method for fish-eye lenses using line features
Photogrammetry Calibration Camera Geometric Close range Sensor
2014/9/9
In this paper, a novel method for the fish-eye lens calibration is presented. The method required only a 2D calibration plane containing straight lines i.e., checker board pattern without a priori kno...
IMPLEMENTATION OF ZOOM-DEPENDENT CAMERA CALIBRATION IN CLOSE-RANGE PHOTOGRAMMETRY
Zoom-dependent calibration self-calibration close-range photogrammetry zoom lens distortion variation
2014/4/28
The application of consumer-grade cameras for photogrammetric measurement has traditionally been subject to the requirement that imagery is recorded at fixed zoom and focus settings. The camera is the...
In photogrammetry a camera is considered calibrated if its interior orientation parameters are known. These encompass the principal distance, the principal point position and some Additional Parameter...
