CRITICAL ASSESSMENT OF CORRECTION METHODS FOR FISHEYE LENS DISTORTION
Fisheye Lens Distortion Camera Calibration,Critical Assessment
2016/7/4
A fisheye lens is widely used to create a wide panoramic or hemispherical image. It is an ultra wide-angle lens that produces strong visual distortion. The distortion modeling and estimation of the fi...
ANALYSE ON IMAGE DISTORTION CAUSED BY CAMERA TILTING ANGLE IN MOSAIC CAMERA
camera mosaic tilting angle image distortion Two-Mosaic Four-Mosaic ratio of GSD change
2016/3/17
Digital aerial photogrammetry has the virtue of high precision and efficiency, but the plane array of single digital camera is not wide enough, so the land coverage and base-height ratio of singledigi...

Quality Assessment of Self-Calibration with Distortion Estimation for Grid Point Images
Self-Calibration Grobner basis Bundle Adjustment Image Distortion Planar Pattern Performance Analysis
2014/9/9
Recently, a camera self-calibration algorithm was reported which solves for pose, focal length and radial distortion using a minimal set of four 2D-to-3D point correspondences. In this paper, we prese...
Method for Measuring Lens Distortion by Using Pinhole Lens
Metrology Vision Camera Calibration Correlation Distortion Pinhole
2014/7/30
In photogrammetric applications, the measurements are conducted on images given by optical imaging systems (cameras). In order to ensure the demanded accuracy, those cameras have to be well calibrated...
