My family has been vacationing at Parlee Beach, NB for nearly all of my life, but the beach has been in the news recently for problems of E.coli and other bacteria in the water. Current testing has revealed the problem to be serious, but so far the sources of contamination have not been definitively identified. Also, the testing that has been taking place has been time consuming and laborious, and generally confined to the main beach itself. I thought it would be cool if the testing area could be expanded, and also simplified, so as to take a shorter length of time between sample collection and final test results.
Due to the ambitious nature of this quest, I have gone to half-time employment at my regular day job, but will still continue to do some contract work on the side, to help make ends meet. The extra hours freed up will be dedicated to making AMOS a reality.
So far the beginning is small, just a raspberry PI Compute module with a couple of Pi V2 Camera modules:
This weekend I have been toying with a couple of different OpenCV library functions for feature detection. I would like to give AMOS some reasonable amount of computer vision so that it can identify obstacles on the open seas and avoid them whenever possible. I did some testing using Harris corner detection and the FAST algorithm for feature detection.

The FAST algorithm seemed to work a lot better and faster, so maybe it will form the basis of AMOS's object avoidance code.
