I was given two photos flown with the X7 and P1. The purpose of the project is to classify the green vegetation through pixel classification. So pixel value consistency is vital. Especially if I am using the same model. Below I have attached an X7 photo and P1 photo. To me, it is easier to identify the green vegetation with the X7 than it is with the P1. I was informed that the P1 provides higher resolution imagery. So why is it harder to identify the green grass, or for that matter any object? I believe the X7 was using the 24mm lenses and the P1 was with the 35mm. I don't hold much knowledge with camera specs, more in charge of the image processing. Could this be a camera issue or a preprocessing/calibration issue? I've found about zero information online except for the basic specs that Zenmuse has released.
I tossed these into QGIS and picked a few points on the yellow line and found the following results:
