| 摘 要： | 由于海部遥感影像的特殊性,使得传统摄影测量定位方法无法满足高精度的海岸带地理信息获取。提出利用潮汐数据转换计算的水边线高程数据值支持海岸带区域网平差,可以大幅度提高海岸带高程定位精度,在四角布设平高控制点条件下,可以提高海岸带高程精度74%。实验结果表示该方法可行,并得出一些有益结论。

| Abstract: | Due to the particularity of ocean remote sensing images,it’s difficult to meet the demands of obtaining hight precision coast zone geographic information with troditional photogrammetry positioning method.The paper has proposed a new method of coast zone block adjustment supported by the depth contours elevation which can be obtiand by transformation of ocean tide datum.It can improve the vertical positioning precision greatly.In the paper,the vertical positioning precision can be raised by 74 percents under the condition of four corner control points.Experiments have proved the feasibility,and obtained some beneficial conclusions. |
