A Satellite Cross-Calibration Experiment

IEEE Geoscience and Remote Sensing Letters, 2004
Recently, the Advanced Earth Observing Satellite 2 (ADEOS-2) was launched (December 14, 2002) successfully, and the Global Imager (GLI) onboard the ADEOS-2 satellite became operational in April 2003. In a first calibration checkup, the radiometric performance of GLI was compared relatively to that of other sensors on different satellites with different

Online cross-calibration of camera and LIDAR

2017 13th IEEE International Conference on Intelligent Computer Communication and Processing (ICCP), 2017
In an autonomous driving system, drift can affect the sensor's position, introducing errors in the extrinsic calibration. For this reason, we have developed a method which continuously monitors two sensors, camera, and LIDAR with 16 beams, and adjusts the value of their cross-calibration.

Truths cross-calibration uncertainty tool

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
This paper describes a set of tools, algorithms and methodologies that have been developed and used in order to estimate the radiometric uncertainty achievable for a Sentinel 2/3 like sensor through in-flight cross-calibration using a well-calibrated hyperspectral SI traceable reference sensor such as the proposed TRUTHS (Traceable Radiometry ...

Cross-calibration of ground and space radar

IEEE International Geoscience and Remote Sensing Symposium, 2003
Presents results from comparing space radar and ground radar to cross-calibrate the Kwajalein polarimetric radar (KPOL) with the spaceborne TRMM Precipitation Radar (PR). Use of self-consistency of polarimetric measurements is implemented to check the absolute calibration of KPOL and is checked against the cross-calibration results of PR and KPOL ...

Cross Calibration by FFT Equalization

Journal of Dynamic Systems, Measurement, and Control, 1997
The classical calibration problem is primarily concerned with comparing an approximate measurement method with a very precise one. Frequently, both measurement methods are very noisy, so we cannot regard either method as giving the true value of the quantity being measured.

Improvement of AVNIR-2 Radiometric Calibration by Comparison of Cross-Calibration and Onboard Lamp Calibration

IEEE Transactions on Geoscience and Remote Sensing, 2009
The Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) on-orbit radiometric performance has been improved through the comparison of cross-calibration and onboard lamp calibration. We proposed a new cross-calibration scheme which uses top-of-atmosphere reflectance functions of satellite zenith angle at temporally and spatially stable ground ...

Cross-calibration between airborne SAR sensors

IEEE Transactions on Geoscience and Remote Sensing, 1993
A comparative study of data acquired by two different airborne synthetic aperture radar (SAR) sensors from the same site is presented. External, ground-target-based calibration has been performed on the NASA/JPL DC-8 SAR C-band data and the DLR E-SAR C-band data collected over the DLR test site in Oberpfaffenhofen.

A study on vicarious calibration and cross calibration for HISUI multispectral and Hyperspectral Imager

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
The Hyperspectral Imager Suite (HISUI) is the Japanese next-generation Earth observation project, which will be composed of hyperspectral imager (185 spectral bands in VNIR-SWIR region with 30 m spatial resolution) and multispectral imager (4 spectral bands in VNIR region with 5 [m] spatial resolution), and is being developed by Japanese Ministry of ...

Assessment of HISUI radiometric performance using vicarious calibration and cross-calibration

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
The Hyperspectral Imager Suite (HISUI) is a future hyper-spectral and multispectral sensor developed by Japanese Ministry of Economy, Trade, and Industry (METI). Radiometric calibration of satellite sensor system is very important for the higher level products with high quality.

Camera calibration by vanishing point and cross ratio

International Conference on Acoustics, Speech, and Signal Processing, 2003
The authors present a unified camera calibration method in which radial distortions can be considered or ignored. The usually tangled process of calibrating intrinsic and extrinsic camera parameters in the zero-distortion case is separated by using vanishing points as calibration points.
