Establishment of continuous flow measurement technology and development of measurement system for groundwater flow using image processing method

利用现有的井内测量设备，对地下水流量进行连续测量是非常困难的。为了解决这个问题，一个独特的带有铰链的浮动传感器被安装在新开发的仪器的底部。在其上部安装了摄像机，用于捕捉浮动传感器头部运动的视频，以测量地下水流量。本研究建立了连续流量测量技术，开发了一种利用图像处理方法和地下水温度、孔隙水压力等其他标准对地下水流量进行简单、连续、同时测量的仪器。

With the currently available in a borehole measurement device, continuous measurement for groundwater flow is extremely difficult. To solve this, a unique floating sensor with a hinge was attached to the bottom of the newly-developed instrument. On its upper part, a video camera was installed to capture video of movement of the floating sensor head to measure the groundwater flow. In this sutdy establishment of continuous flow measurement technology and developed an instrument that enables simple, continuous and simultaneous measurements for groundwater flow using image processing method and other criteria including groundwater temperature and pore water pressure etc..
