Re: Optimal board for vision processing
Quote:
On Team 11 we had very little luck getting the cRIO to handle all we asked from it with Java doing vision and everything else and in some example cases even getting the examples to work. The RoboRio is faster so that will help. It is less picky so that will also help. I believe I asked around on ChiefDelphi in the past for Java vision examples for the cRIO that actually work. I would love to see working Java vision examples on the RoboRio. Perhaps video of them working. I have not involved myself with the beta work MORT is doing on the RoboRio and Java in this regard so it may exist. Quote:
I also spent part of each competition chasing around teams sending video back to the driver's station in ways that messed with the field at the request of the FTA. Very competent people were having issues with this so I do not think it is quite so cut and dry. If anyone wanted I could toss that data together for the events at which I volunteered in MAR. Additionally: I would like to add there is a hidden cost to the embedded and single board computers. It is the same hidden cost of the cRIO especially back 3 or more years ago when the 8 slot cRIO was the FIRST approved system. How many of these do you have knocking around to develop on? Think about it: general purpose laptops are plentiful and therefore anyone with a laptop (increasingly all the students in a school) could snag a USB camera for <$30 and start writing vision code. If you are using old phones you can get the whole package probably for $100 or less and probably your students are already glued to the phones they use too often every day now. On the other hand if you buy a development board for nearly $200 how many people can actively develop/test on it? If a student takes that board home how many other students can work and be confident that what they are doing will port to that system? Vision is a big project and more importantly you can often play a FIRST game without it. Is it better to use laptops you probably already have or commit to more proprietary stuff you might have to buy multiple of and then....if that product goes out of production...do that all over again if you even really use it? Is the cost justifiable? Last edited by techhelpbb : 15-10-2014 at 16:35. |
