In the days before the demo, I modified the pixel to inch parameter to fit the size of the meat within the range of error. This value is hardcoded instead of dynamically determined because the meat is anticipated to be a fixed distance from the camera in the final product, so having fixed values instead of a reference point is better.
Before the demo, I was able to download the necessary libraries and files onto the Jetson, however I lacked enough adaptors to get the keyboard and the camera both working at the same time, so I was unable to get that working before the demo. I was able to get the necessary adaptors to get the Computer Vision working on the Jetson during Carnvial.
