鱼眼镜头目标方位测定的两种方法对比研究

Two methods for the measure of target location based on fisheye lens

通过分析鱼眼镜头的成像原理,对比出两种基于鱼眼镜头目标方位测定的方法.一种方法通过畸变校正测定目标方位,另一种则是本文提出的方位角与像素坐标关系法测定目标方位,两种方法都快速的、高效的测定出鱼眼图像中目标的方位.本文分别研究两种方法的理论基础并在理论的基础上进行了对比实验,通过对实验后数据的比对,分析出其中更精确的方法,从而将这种方法应用于天文测定中.

Through the analysis of fisheye lens imaging principle,compares two kinds of method for the measure of target location based on fisheyes lens. One method using distortion correction to measure the target location,the other use the relation method between location and pixel coordinate to measure the location of the target. Two methods are all with a fast and efficient rate to measure the target location in the fisheye image. This paper will respectively introduce the theory of the two methods and compare the experiment,getting the more accuracy method when we comparing the date of experiment,and using it in the astronomical measure.
