Re: Grip Image processing
From experience shoot at the one on the right (i.e. the largest X value). The one on the left is a reflection from the driver station glass seen when you're trying to shoot in auto from the spybot...

Re: Definitive Guide to Using the Jetson TK1/TX1?
Depends on what you mean by etc, but to install the latest OS on the board use JetPack - https://developer.nvidia.com/embedded/jetpack. That will give you the latest OS, OpenCV, CUDA, and so on. At...

Re: Help: Vision hsv value issues.
Can you be more specific on what the problem is? What libraries are you using?
Do you have a set of values and the code doesn't seem to apply them? Probably need to see code. OpenCV has an...

Re: Team 900 Role Call
Shhh! Don't let anyone know we're porting the vision code onto a Commodore 64 running BASIC. That's a supported platform for ROS, right?

No argument. There's a good bit of science there, but probably just as much trial and error...

Re: What Did you use for Vision Tracking?
I'll add that we use ZeroMQ to communicate between the TX1 and Labview Code on the RoboRIO. That turned out to be one of the least painful parts of the development process - it took like 10 lines of...

Re: 20 point auto club
I was hoping video would be out there, but no luck. In any case, 900 has a pretty consistent 20 pt auto going. We've hit it going over both the rock wall and rough terrain. Not sure if we've had a...

Re: What language do you use?
At this part of build season, mostly foul language.
We use LabView for the robot and C++ w/OpenCV, Caffe, Eigen3 and some other libraries for vision processing. We have python, perl and bash...
