A crop zone allows you to ignore static objects in the cameras field of view.
For example, when the camera can see a part of the vehicle it is mounted on (itself), you should draw a crop zone to mask out the vehicle so the AI does not detect it.
Below are screenshots of a Blindsight camera installed on a grader to demonstrate the need for a crop zone.
The first screenshot shows the AI detecting the rippers of the grader - pretty impressive! But not the type of detection we care about.
2. Here is a screenshot of the crop zone we've drawn to mask out the part of the vehicle that is being detected.
3. Here is a screenshot of what the AI will see now that we have drawn a crop zone.
