Debug Gate Detection

[anijjar]

Background: The gate detection code does not run correctly. We have rosbag files containing sample videos that I can supply.
Goal: Get the gate detection code working in the vision package.

Note: This task will require knowledge on how openCV processes data and a little bit of ROS. speak with robert on OpenCV and myself on ROS.

Issue pinpointed to BuoyDetector.cpp line 20 (hash 726cc87). Two bugs were discovered:

1. No default value for buoy_type provided to constructor, no error handling
2. OpenCV complains that parameter detector.buoy_img is not of type CV_8U. Conversions between types is being worked on

[robwasmann]

Anton, I agree that there should be a default case and error handling in BuoyDetector.cpp, but the gate detection is in GateDetector.cpp. Should this bug you found go into Issue #17 perhaps?

[AntonNiko]

That sounds reasonable, I will copy that note into #17
