Interesting concept. I think that the details will vary a lot from project to project, depending on the material, whose level needs to be measured and the position of the camera.

By the way (again), there are other non-contact methods for level measurement, such as ulrtasound for example. Here's a list of common level sensing principles: http://en.wikipedia.org/wiki/Level_sensor
