摘要
在足够远的距离上,物点会成像在透镜的焦平面处,针对这一成像特点,本文提出一种基于光学成像的目标定位方法。计算机通过CCD摄像系统获取到目标的图像,对目标图像进行数字图像处理并计算出目标方位角和高度角,达到对目标定位的目的。通过对太阳的精确定位,验证了此定位方法的可行性,并分析了图像的几何畸变对此方法定位精度的影响。
Image of the object presents on the focal plane from long enough distance. For the optical imaging feature, a corre-sponding location method is proposed. First the target is imaged by image camera. Then connected with computer, the digital image is processed and the azimuth angle and pitching angle of the target are worked out so that the target is located. With the method sun is located accurately and the experimental result justifies the exactitude of the location arithmetic. This paper analyses factors on location precision due to geometry distortion.
