Pix4Dcapture takes less images than DJI Pilot App

In our company, we use a DJI Mavic 3M Drone. We wanted to compare the image capture results of the already installed DJI Pilot app and Pix4dcapture. Our goal is to feed the images into a photogrammetry software to reconstruct the mapped area. The main advantage that we are seeking of Pix4Dcapture is its ability to let the drone fly as low as 10m above takeoff point. However, Pix4Dcapture takes less images than the DJI Pilot app with lesser overlap. For an example area, the DJI Pilot app takes around 250 images while Pix4Dcapture takes around 70 images only!

The curious thing is that in both apps the frontal overlap setting is 80% and the side overlap is 70%. Shouldn’t the Pix4dcapture app therefore take more images than DJI Pilot since it flies with a lower flight altitude? Or is there a setting that we are missing in the app?
