Code:
[cRIO] at edu.wpi.first.wpilibj.templates.VisionSampleProject2013.autonomous(VisionSampleProject2013.java:85)
This shows the problem is happening in line 85 of the project. Did you uncomment the following line?
Code:
//thresholdImage.write("/threshold.bmp");
By default, the example project reads data from testImage.jpg on the cRIO (which probably doesn't exist). Have you either uploaded the testImage, or modified the code to use the camera?
Have you read the vision processing tutorial?
