A NOVEL TECHNIQUE FOR PRECISION GEOMETRIC CORRECTION OF JITTER DISTORTION FOR THE EUROPA IMAGING SYSTEM AND OTHER ROLLING-SHUTTER CAMERAS
Europa photogrammetry jitter geometric correction active-pixel sensors
2018/5/14
We use simulated images to demonstrate a novel technique for mitigating geometric distortions caused by platform motion (“jitter”) as two-dimensional image sensors are exposed and read out line by lin...
A ROBUST METHOD FOR FUNDAMENTAL MATRIX ESTIMATION WITH RADIAL DISTORTION
Machine Vision 3D Reconstruction Robust Method Fundamental Matrix Epipolar Geometry SVD
2018/5/16
Fundamental Matrix Estimation is of vital importance in many vision applications and is a core part of 3D reconstruction pipeline. Radial distortion makes the problem to be numerically challenging. We...
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...

Cannon–Thurston maps, subgroup distortion, and hyperbolic hydra
subgroup distortion hyperbolic hydra
2015/8/26
We prove that Cannon–Thurston maps are well–defined (that is, subgroup inclusion induces a map of the boundaries) for heavily distorted free subgroups inside the family of hyperbolic groups known as h...
Experiment on parameter selection of image distortion model
Calibration Simulation Camera Digital Non-Metric Distortion Model Experiment
2015/8/24
Most of current camera calibration methods for a non-metric digital camera adopt polynomials of image coordinates composed of terms representing the correction to the principal distance, the offsets o...
