本文主要目的是以亮度分佈演算法為核心，並將其套用於自行開發之星象模擬器，提高其顯示位置與亮度的精確度，減少因實驗所產生之誤差，協助星象追蹤儀之開發。本文開發之模擬軟體，可模擬星象追縱儀擷取之恆星星體影像。如配合星象追縱儀之光機部份，其整合可完成星象模擬光學系統。本星象模擬器能夠應用於星象追縱儀之開發時使用，其優點在於不受天候限制，能夠提供己知精確度的星體方位影像，能夠選用方位不受地平限制。 The main purpose of this thesis is the distribution algorithm of star brightness,and we use the algorithm in star simulator which develop by ourself for improving the accuracy of simulated star position and star brightness and eliminating the error which produce from star simulator.It also can help the development of star tracker.Our star simulator can simulate the captured image from star tracker.We can simulate the whole optic system of star simulation, If we operate star simulator with the optic part of star tracker.The advantage of the test system with distribution algorithm of star brightness is providing a known accuracy star image and discarding the limitation of weather and position on the ground based test.
