摘要: 为了解决低空摄影测量、建筑摄影测量等领域中缺乏明显特征点给相对定向带来的难题,本文基于广义点摄影测量原理,提出利用多种同名影像特征进行相对定向的新方法。详细论述了基于同名直线和圆曲线进行独立法相对定向和连续法相对定向的数学模型。实际数据的试验结果表明,该方法切实可行,能够获得稳定的相对定向结果。

Abstract: To resolve the current problems of relative orientation caused by lacking of obvious feature points in applications of industrial and architectural photogrammetry, a new method of relative orientation based on multiple types of conjugate features is proposed on the basis of the theory of generalized point photogrammetry. The models of independent and continuous relative orientation by conjugate lines and circular curves are addressed respectively. Experimental results show that the proposed approach is feasible in practice, and can get reliable relative orientation results even in the case of a few conjugate points.
