Wave measurements, such as height and period, are important in understanding estuarine and coastal processes as well as air-sea interactions, which are important in the validation of hydrodynamic models and improvements in the parameterizations needed for atmospheric models. This paper presents and evaluates a relatively inexpensive and portable video-based method of measuring the nearshore wave properties of a coastal estuary. The proposed system uses a GoPro camera along with a set of scripts to perform camera calibration and remove lens distortions. Significant wave heights and peak frequencies are then extracted from the video without the need for the ground control points (objects of known physical location in relation to the camera) as used in previous studies. By not relying on ground control points, the system becomes portable and easy to deploy, allowing the collection of wave data from various locations on the estuary. The estimated significant wave heights and peak frequencies were validated with a sonic wave gauge located in the camera's field of view. Percent error and RMSE were calculated and indicate the proposed method is robust and the errors (estimated at less than 6%) are consistent with other video-based methods that use multiple cameras and ground control points.

波浪测量（例如高度和周期）对于了解河口和沿海过程以及海-气相互作用非常重要，而这对于验证流体动力学模型和改善大气模型所需的参数设置非常重要。本文提出并评估了一种相对便宜且基于便携式视频的方法，用于测量沿海河口的近岸波特性。拟议的系统使用GoPro摄像机以及一组脚本来执行摄像机校准并消除镜头畸变。然后，从视频中提取出重要的波高和峰值频率，而无需像以前的研究中那样使用地面控制点（相对于摄像机已知物理位置的物体）。通过不依赖地面控制点，该系统变得便携式且易于部署，从而可以从河口的各个位置收集海浪数据。估计的有效波高和峰值频率通过位于摄像机视场中的声波计进行验证。计算了误差百分比和RMSE，表明所提出的方法是健壮的，并且误差（估计小于6％）与使用多个摄像机和地面控制点的其他基于视频的方法一致。
