[robocup-small] robocup-small Digest, Vol 55, Issue 4

[Stefan Zickler]

Hi All,

thanks for the discussion on this. There is a point I would like to
add besides the ones mentioned by RoboFEI:

One of the main goals and benefits of SSL-Vision is to finally ease
the ridiculous setup and organizational struggles of the SSL. By
making SSL-Vision mandatory (and providing a single set of cameras + a
vision server per field), teams will be able to switch fields easily
(like in any other league), thus allowing a more flexible game
schedule. Furthermore, time between games can be used for actual work
on A.I. and robot testing, instead of calibrating cameras and chasing
ladders around. Scalability to more cameras is another advantage, as
RoboFEI mentioned.
If we were to make the use of SSL-Vision optional then we would
effectively keep the status quo, having non-participating teams still
be bound to their fields and blocking the field by putting up their
own cameras/equipment.

Of course nobody wants to block innovation. This question has already
been carefully addressed during the previous road-map discussions and
during development of SSL-Vision (the SSL-Vision paper of the 2009
proceedings also touched upon this topic). That is why, as RoboFEI
pointed out, SSL-Vision is an open-source project, and is very modular
in its design. If you or your team think that you have an improved
vision algorithm, or an additional feature that SSL-Vision is missing
then this can be easily evaluated and added to the codebase. In fact,
we are thankful for any additional developers. :-)

Best Regards,
Stefan

With a standard vision, leaving aside the argument that new teams would benefit from the availability of such system (as even as optional this benefit holds), you still have other good reasons:
