摘要 | Since several hundreds of CCD images are obtained with the CCD camera in the Lower Latitude Meridian Circle (LIMC) every observational night, it is essential to adopt an automatic processing method to find the initial position of each object in these images, to center the object detected and to calculate its magnitude. In this paper several existing automatic search algorithms searching for objects in astronomical CCD images are reviewed. Our automatic searching algorithm is described, which include 5 steps: background calculating, filtering, object detecting and identifying, and defect eliminating. Then several existing two-dimensional centering algorithms are also reviewed, and our modified two-dimensional moment algorithm and an empirical formula for the centering threshold are presented. An algorithm for determining the magnitudes of objects is also presented in the paper. All these algorithms are programmed with VC++ programming language. In the last our method is tested with CCD images from the 1m RCC telescope in Yunnan Observatory, and some primary results are also given. |
