| 摘 要： | 提出了基于潮汐变化、滩面复杂度以及不同影像数据源的多种算法的关联适配模型。针对两类水边线提取结果,提出适合于不同类型的水边线精度评价模型。以渤海湾某海域的潮滩影像为研究对象,对方法的有效性进行了验证。结论表明:提出的适配模型有助于提高运算效率,降低运算复杂度,对各种潮情和滩面的水边线提取结果准确,且精度评价的可信度高,可为大范围潮滩数字高程模型的构建提供数据支持。

| Abstract: | A correlation model of multiple algorithms is put forward based on tide variations, complexities of beach faces and different data sources of images . The accuracy assessment models are put forward aimed at two kinds of waterline detection results . The effectiveness of the method is verified by researching tide flat images of some sea area in the Bohai Bay. The results show that the correlation model helps to improve the calculating efficiency and reduce the calculating complexity,and that the extraction of beach face waterlines under different tide conditions is accurate and of high reliability in accuracy assessments,which can provide data support for the establishment of the digital tide flat elevation model. |
