| 摘 要： | 摄影测量技术已经成为一种有效的测量方法,并广泛应用。本文基于平差的理论模型,导出了由摄影测量所得地物特征点(广义点)的位置误差模型和误差传播模型,并进一步分析了观测值的质量特征(精度,可靠性,误差椭圆),通过以地物作为具体实例方案证明所得结论具有一定的参考价值。

| Abstract: | Photogrammetry has become an effectual measuring method, and was widely used. Based on adjustment theory model, this paper aims to derive position errors and error propagation model of the ground feature point (generalized point). For further analyzing the qualitative characters (such as precision, reliability, error ellipse) observed quantity, a concrete instance is given to certificate the proved conclusion has reference value on a certain degree. |
