islanding detection methods for microgrids
امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...
15 صفحه اولCalibration and Registration for Precise Surface Reconstruction with TOF Cameras
This paper presents a method for precise surface reconstruction with time-of-flight (TOF) cameras. A novel calibration approach which simplifies the calibration task and doubles the camera’s precision is developed and compared to current calibration methods. Remaining errors are tackled by applying filter and error distributing methods. Thus, a reference object is circumferentially reconstructe...
متن کاملNew approach for calibration of pixelated scintillation detectors of intraoperative gamma cameras
Introduction:SURGEOSIGHT is a dedicated intra-operative hand-held gamma camera designed and manufactured by our team to be used for lymphoscintigraphy. Although conventional gamma cameras are widely used, they lack the capability of the sentinel lymph node (SLN) imaging in the operation room. Like conventional gamma cameras it is necessary to calibrate SURGEOSIGHT for linearity...
متن کاملComparing Self-calibration Methods for Static Cameras
Extended Abstract Many methods have been developed in the last few years to self-calibrate cameras , but few works have addressed a comparison of such methods to provide the user with hints on the suitability of certain algorithms under particular circumstances. The few of these works that analyze self-calibration methods have concentrated on the study of the influence of some factors [1] [2] o...
متن کاملCamera Calibration without Feature Extraction
This paper presents an original approach to the problem of camera calibration using a calibration pattern. It consists of directly searching for the camera parameters that best project three-dimensional points of a calibration pattern onto intensity edges in an image of this pattern, without explicitly extracting the edges. Based on a characterization of image edges as maxima of the intensity g...
