    • The present invention relates to an image matching method and a system for performing the same. According to the present invention, a geometric correction is performed by: extracting a matching pair which is a global matching object by using a specific point which is extracted from a reference image and an object image based on an SIFT; primarily minimizing a difference of a coordinate system between two images through an affine transformation using the extracted global matching pair; extracting a local matching pair which is a local matching object by using a parameter which is extracted using a simulated annealing; and applying global/local transformation model formulas to the local matching pair which remains after an outline rejection by using the distance information and local direction information of each local matching pair.
    • 图像匹配方法及其执行方法技术领域本发明涉及一种图像匹配方法及其执行方法。 根据本发明,通过以下步骤进行几何校正:通过使用从参考图像提取的特定点和基于SIFT的对象图像提取作为全局匹配对象的匹配对; 主要通过使用提取的全局匹配对的仿射变换来最小化两个图像之间的坐标系的差; 通过使用使用模拟退火提取的参数来提取作为本地匹配对象的局部匹配对; 以及通过使用每个局部匹配对的距离信息和局部方向信息,将全局/局部变换模型公式应用于在轮廓抑制之后保留的局部匹配对。

    • PURPOSE: A digital phase locked loop by a measurement of a phase error is disclosed to provide a reference time of an artificial satellite by compensating for an error and a noise of an IPPS signal from a GPS receiver. CONSTITUTION: The digital phase locked loop synchronizes a GPS 1PPS signal with a UTC. A phase error detector(21) calculates an error between a GPS 1PPS signal and internal 1Hz of a processor according to a reference signal. A software filter(22) reduces jitter amount of a compensated 1PPS signal which is provided to a DPLL based on the error calculated by the phase error detector(21) using a digital filter method. An error compensator(23) compensates for the 1PPS signal by the error compensated by the software filter(22) and provided the compensated IPPS signal to an input terminal of a DPLL.
