Re: Image Cropping/Mask?

We have the camera mounted pretty securily, using the bolt on it, that isn't an issue, (unless we start hitting 6.5K RPM...)
The shooter itself is fairly precise, hitting within less than 1 foot consistently.

We used camera tracking code to rotate our turret head, and using the same algorithim for rotation, with the higher resolution image it would take too long to process and start to overshoot. When we used the same algorithim and a smaller resolution image, it locked in without any osiciallation.

We calcuated the whole 4x less data to process also, but we feel it will be worth having the higher resoultion to process with, in order to gain distance and more accurate lock on with the camera.

The C code that NI Vision Assisstant created is throwing an error, something about one of the imaq functions not being correct. I will try and get that posted within 2 hours.
