Airborne laser scanner technique is broadly the most appropriate way to acquire rapidly and with high density 3D data over a city.Once the 3D Lidar data are available, the next task isthe automatic da...
ESTIMATING THE ESSENTIAL MATRIX:GOODSAC VERSUS RANSAC
essential matrix robust estimation RANSAC structure from motion
2015/8/31
GOODSAC is a paradigm for estimation of model parameters given measurements that are contaminated by outliers. Thus, it is an alternative to the well known RANSAC strategy. GOODSAC’s search for a prop...
Epipolar Rectification for CARTOSAT-1 Stereo Images Using SIFT and RANSAC
Epi-polar rectification image matching SIFT, Ransac Cartosat-1 stereo

Cartosat-1 provides stereo images of spatial resolution 2.5 m with high fidelity of geometry. Stereo camera on the spacecraft has look angles of +26 degree and -5 degree respectively that yields effec...
Improving HySpex Sensor Co-registration Accuracy using BRISK and Sensor-model based RANSAC
Matching Estimation Orthorectification Photogrammetry Hyper spectral
2014/12/4
In this paper a method to improve the co-registration accuracy of two separate HySpex SWIR and VNIR cameras is proposed. The first step of the presented approach deals with the detection of point feat...
