A method to video tidal wavelets against a vertical wall and map the wave top to arrive at an average amplitude

I want to build an app - some functionality includes averaging the height of wavelets when i video 10 waves. I’m not talking ocean waves here, but small swells against a tidal wall - assume a wave height limit of 0.5m

probably simpler to install whatever apparatus is customarily being used to monitor water levels… but evaluate it several times a second?

video is a terrible choice. not robust at all. you’d have to either control or deal with all kinds of variations of the environment, specifically lighting, but not just that.
