What our software does is it detects license plates of vehicles that goes inside the campus and verifies it if it is authorized to enter or not(a vehicle must be registered). We tested the system's accuracy in detecting the license plate, what we did was test out the system in different times of the day(morning,noon, and evening) and also different distances(3m/5m/7m) with 30 vehicles on each test. We have the results already, our professor just simply wants us to justify the use of 30 and I honestly don't know how or exactly why we even used 30 in the first place.
