Camera particleToImagePercent not working

[TPNigl]

So what we are trying to do currently is get a feed from the camera stating the percentage of the area of the soccer ball is compared to the whole camera image. I am getting odd numbers though. They have ranged from .0075 to 11.86. I have no clue how to read these and I haven't been able to find it. Also, we keep getting a watchdog error with the following code in teleopContinuous. Any ideas? Thanks everybody!

Watchdog.getInstance().feed();
         Timer.delay(10.0);
         int numParticle = 0;
         
         m_autoPeriodicLoops++;
         numParticle = 0;

         try
         {
            if (cam.freshImage())
            {
                colorImage = cam.getImage();
                binaryImage = colorImage.thresholdRGB(80, 110, 150, 180, 80, 110);
                ParticleAnalysisReport[] par = binaryImage.getOrderedParticleAnalysisReports();
                ParticleAnalysisReport par2 = par[0];

                double percentageSum, soccerBallPercentage;

                m_DriverStationLCD.println(DriverStationLCD.Line.kUser3,1,"" + par[numParticle].particleToImagePercent);
                numParticle++;

                /*for (int i=0; i<par.length-1; i++)
                 {

                    percentageSum = par2.particleToImagePercent;
                    soccerBallPercentage = percentageSum/par.length;
                 }*/
            }
         }

         catch (AxisCameraException ex)
         {
            ex.printStackTrace();
         }

         catch (NIVisionException ex)
         {
            ex.printStackTrace();
         }

Have you tried to do this with vision asst? Often, you need to explore a handful of images looking for the right numbers, perhaps run a filter over the image first, etc.

Figuring out these steps with nothing but printf can be quite difficult.

We don't have Vision Assistant. Is there a free download for it?
