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...
INSAR UNWRAPPING ERROR CORRECTION BASED ON QUASI-ACCURATE DETECTION OF GROSS ERRORS (QUAD)
QUAD, InSAR, Unwrapping Error Correction, Gross Error, L1-norm
2018/5/14
Unwrapping error is a common error in the InSAR processing, which will seriously degrade the accuracy of the monitoring results. Based on a gross error correction method, Quasi-accurate detection (QUA...
THERMAL TEXTURE SELECTION AND CORRECTION FOR BUILDING FACADE INSPECTION BASED ON THERMAL RADIANT CHARACTERISTICS
building facade thermal image calibration texture mapping terrestrial 3D model
2018/6/4
An automatic building façade thermal texture mapping approach, using uncooled thermal camera data, is proposed in this paper. First, a shutter-less radiometric thermal camera calibration method i...
SHUTTER-LESS TEMPERATURE-DEPENDENT CORRECTION FOR UNCOOLED THERMAL CAMERA UNDER FAST CHANGING FPA TEMPERATURE
Uncooled Thermal Camera Fast Changing FPA Temperature Shutter-less Temperature-dependent Correction Radiometric Calibration FLIR GEV
2017/7/13
Conventional temperature-dependant correction methods for uncooled cameras are not so valid for images under the condition of fast changing FPA temperature as usual, therefore, a shutter-less temperat...
Correction of source-rock permeability measurements owing to slip flow and Knudsen diffusion: a method and its evaluation
Shale gas Permeability Knudsen diffusion Unconventional reservoir Source rock
2018/4/2
Source-rock permeability is a key parameter that controls the gas production rate from unconventional reservoirs. Measured source-rock permeability in the laboratory, however, is not an intrinsic prop...
TLS FIELD DATA BASED INTENSITY CORRECTION FOR FOREST ENVIRONMENTS
Terrestrial Laser Scanning Forestry Signal Amplitude Intensity Correction
2016/11/30
Terrestrial laser scanning (TLS) is increasingly used for forestry applications. Besides the three dimensional point coordinates, the 'intensity' of the reflected signal plays an important role in for...
