摘要
基于在物距与焦距之比远大于 1时摄像系统成像模型可用平行投影近似的事实 ,充分利用空间目标的几何先验知识 ,提出了一种从单站经纬仪等光测设备获得的图像确定火箭等空间目标三维姿态的方法 ,避免了多站图像的立体匹配。仿真实验和实际应用结果表明 :方法精度高 。
Based on the fact that the camera model can be described as parallel projection model when the object camera distance is bigger than focal length greatly, the article presents an approach of determination of object's 3D pose from mono view, using the knowledge of object's figuration, avoiding stereo matching The synthetic and real application show the approach can give precision and stable results
