Navigation of satellite measurements without ground control points

International Journal of Remote Sensing, 1993
Abstract The minimum of information on satellite dynamics (a part of celestial mechanics) which is needed to navigate operational polar orbiting meteorological satellites either for direct or inverse referencing without ground control points, is presented. This software is tailored to the orbit information available.

Boresight Calibration of Airborne LiDAR System Without Ground Control Points

IEEE Geoscience and Remote Sensing Letters, 2012
This letter proposes a new method for boresight misalignment calibration of the charge-coupled device (CCD) camera which is one component of an airborne light detection and ranging (LiDAR) system without ground control points (GCPs). In the calibration, tie points in overlapping areas are first selected, and then, a multibaseline forward intersection ...

Ground Truth generation from automatic recognition of ground Control Points

2016 24th Signal Processing and Communication Application Conference (SIU), 2016
Production of Ground Truth (GT) data for remotely sensed images is an important step for evaluation of accuracy assessment of different analyzes such as classification, geo-locatining and object detection. Geo-locationing systems for images taken from different platforms such as ground and laboratory tripod are not widespread and useful.

An Optimization Method on Ground Control Point Distribution

Advanced Materials Research, 2011
With the development of remote sensing, the data quantity of remote sensing image is increasing tremendously. It brings a huge workload to the image geometric correction through manual ground control point (GCP) selection. GCPs automatically selected based on software is one of the effective methods to cut down manual operation.

Global stereo matching leveraged by sparse ground control points

CVPR 2011, 2011
We present a novel global stereo model that makes use of constraints from points with known depths, i.e., the Ground Control Points (GCPs) as referred to in stereo literature. Our formulation explicitly models the influences of GCPs in a Markov Random Field.

MUlti information based Ground Control Points selection method

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
Ground Control Points (GCPs) are one of the most important data used in many fields of Remote Sensing. The number and distribution of GCPs are always the key factors for the success of some researches. A GCPs selection method by integrating the three dimensional spatial information (i.e.
