| 摘 要： | DMC(Digital Mapping Camera)是目前广泛使用的框幅式航空传感器。该文利用武汉大学建设的永久性嵩山航空几何检校场,对DMC在不同航线结构、不同控制数量及分布以及不同平差模型下的几何精度进行了对比分析和评估。实验结果证明,构架航线和控制点分布对DMC几何精度影响有限,但带附加参数的平差模型可以显著提高其几何学精度。

| Abstract: | DMC(Digital Mapping Camera)is a kind of frame type aerial sensor widely used in recent years.By using Henan Song Mountain aerial calibration test field built by Wuhan University,the attainable geometric accuracy of DMC imagery is comparativly analyzed and evaluated in different airline structure,different control points distribution and different adjustment models.The results prove that the distribution of route structure and control points have limited effect on data accuracy of DMC in basic camera model,while they can significantly improve its geometric data accuracy in the adjustment model with self-calibration. |
