Distributed Smart Camera Calibration Using Blinking LED
Smart camera networks are very powerful for various computer vision applications. As a preliminary step in the application, every camera in the scene needs to be calibrated. For most of the calibration algorithms, image point correspondences are needed. Therefore, easy to detect objects can be used like LEDs. Unfortunately, existing LED based calibration methods are highly sensitive to lighting...
متن کاملSingle fiber reflectance spectroscopy calibration.
To accurately determine sample optical properties using single fiber reflectance spectroscopy (SFR), an absolute calibration of the reflectance is required. We investigated two SFR calibration methods, using a calibrated mirror and using the Fresnel reflection at the fiber tip as a reference. We compared these to commonly used calibration methods, using either Intralipid-20% in combination with...
متن کاملRequirements for calibration in noninvasive glucose monitoring by Raman spectroscopy.
BACKGROUND In the development of noninvasive glucose monitoring technology, it is highly desirable to derive a calibration that relies on neither person-dependent calibration information nor supplementary calibration points furnished by an existing invasive measurement technique (universal calibration). METHOD By appropriate experimental design and associated analytical methods, we establish ...
متن کاملCorn Density Measurement by Near-infrared Transmittance
A corn density calibration was developed for a near-infrared transmittance instrument (Infratec 1225). The calibration sample set included 96 corn samples grown in various locations of the United States. Samples were selected by principal component analysis (PCA) from a larger set of 410 samples, representing the 1986 through 1992 crop years. Samples for instrument and temperature stabilization...
متن کاملCalibration of ACS Prism Slitless Spectroscopy Modes
The Advanced Camera for Surveys is equipped with three prisms in the Solar Blind (SBC) and High Resolution (HRC) Channels, which together cover the 1150 – 3500 Å range, albeit at highly non-uniform spectral resolution. We present new wavelengthand flux calibrations of the SBC (PR110L and PR130L) and HRC (PR200L) prisms, based on calibration observations obtained in Cycle 13. The calibration pro...
