Hello All,
Q: Can you show me a photo of a ruler, taken with your drone camera, flying or static, showing the graduation marks?
For an application seeking for structural inspection at hardly accesible places in buildings, i am needing to see cracks and corrosion details; hence i am more interested in taking photos at 1m or less, rather than panoramic shots. For such i am interested in acquiring a DJI Drone, though i am not decided which i should.
I went to a DJI store last friday, and I asked the sellers for some photo trials with their Phantom 4 Pro drone, under static conditions, and after setting several configurations for the ISO, Shutter, Aperture and White settings, we were unable to obtain a photo in which the rule graduation appear visible. In every photo, the rule graduation appeared blurred, making impossible to use the device for the aforementioned purpose.
Considering the P4 drone features a 4:3, 4860x3648 px camera, leading to a 0.37mm/px resolution estimate by taking photos at less than 1m, in theory the camera should be able to capture the required level of detail -the graduation of a rule-, and also the indicated specs are better than the cameras embedded in standard smartphones -which normally accomplish this objective-.
What we are doing wrong?. Are the DJI cameras indeed unable to take photos of a rule?.
Thank you for your time and aid.
