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...
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...
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...
