对海滩系统演变规律的准确把握，依赖于可靠、连续、长期的测量数据。由于Argus视频监测系统具有实时、低成本、操作简单、适应性强、分辨率较高和可提供连续数据等优点，因此，近年来该技术发展迅速，研究应用领域逐渐扩大。在简要说明Argus系统组成的基础上，详细介绍了该系统在我国海滩研究中的应用情况，分析了所提取数据的精度。结果显示垂向误差平均值为0.145 m，平面距离误差平均值为11.73 m，误差大小与到Argus观测站的距离有很大关系，距离越近，误差越小。Argus系统在国外海滩研究中已经获得了比较广泛的应用，而国内尚处于起步阶段，未来有望在海岸工程建设评估、近岸水动力监测与地形反演、海滩旅游管理与河口沙嘴动力地貌变化研究等方面提供更强大和完善的技术支撑。

Reliable, continuous and long-term data is needed in order to understand precisely the evolution of a beach system. Because of the advantages of real-time, low cost, simple operation, strong adaptability, high resolution and continuous data, Argus video monitoring system has developed rapidly in recent years, and its research and application fields have gradually expanded. Composition of the Argus system was briefly introduced, and the application of this system in beach research in China was described, and the accuracy of the extracted data was analysed. It was shown that the average vertical and plane distance error is 0.145 m and 11.73 m respectively, which depends on the distance from Argus observatory. Argus system has been widely used in beach research abroad, but it is still in the early stage in China. In the future, it is expected to provide more powerful and perfect technical support in coastal engineering construction evaluation, coastal hydrodynamic monitoring and bathymetry inversion, beach tourism management and research on morphodynamic evolution of estuary sand spits.

Key words: Argus system, Beach study, Data extraction, Video monitoring.
