Abstract

In order to measure the shallow wave velocity and improve the accuracy of traditional observation by naked eyes, we design the measuring device of shallow wave velocity. We use dripping to start the shallow wave, capture the image at a fixed time interval for the video of shallow wave, and get grayscale processing. According to the grid images with grayscale quantitative value, the place of crest and trough can be located and then we can get the shallow waves velocity. After application test and literature verification, the device is not only easy to operate and construct but also accurate to measure. Besides, this method of measure can be applied to the task about the image processing, which is difficult for naked eye to observe.
