field lines become obstacles when looking down

[josiahw]

this is only an issue when looking so far down that field lines go off the top of the screen.

Yeah this has been known as a problem since the method was first implemented - problem is that I can't think of a fix that won't cause white robots etc. to be unseen as obstacles.

when we are looking below a certain angle, ignore obstacles?

Not a complete solution, there are angles at which the lines are still obstacles, but which we still need to see obstacles for avoidance. I'll put this method in for robocup though.

You may be able to use the fact that the lines are white and most of the real obstacles are not to help filter these cases.

however with the exception of 1 team last year, they were not :)

Yeah I just don't want to disable our ability to see them as obstacles for the rare occasion when we see a line that occurs as one - when something like a head angle check might reduce this occurrence to low enough not to be an issue.
