Re: Vision Tracking from the Dashboard

The code that didn't work on the classmate ... Can you describe what camera resolution and what frame rate you were using with the default code?

As mentioned, the classmate is faster than the cRIO. The cRIO is pretty capable for an industrial controller, but is a 400MHz RISC architecture from the 90's. It has no vector instructions and can achieve 760 MIPs. By comparison, an ARM Cortex is more like 90, an Atom is a few thousand, and an i7 laptop is more like 80K.

The requirement scale linearly with frame rate and linearly with pixels. Note that pixels scale by X*Y, meaning that small, medium, and large images scale as X, 4X, and 16X. This is an estimate because the JPEG compression doesn't necessarily follow this prediction, and most but not all image processing is integer based.
