my experience with AP 2.5 for photogrammetry

after 4 years of doing many failed attempts with APM and inexpensive tool for Photogrammetry and Precision agriculture today and come to the conclusion that APM is an inexpensive tool that can be very useful for these applications. for less than $ 4000 can build a drone with very professional results.

here I leave an example of the result and obtained so far.

    Hello,

    My next work with APM 2.5. 

    MaxiSwift II, Canon SX260HS with built-in GPS, photos every 2 sec.

    3 flights at 100 + 1 flight at 150 m AGL, approx 2000 photos.

    For this ortophoto generation was used approx 1400 photos.

    Software - AGISoft PhotoScan. 

    Area: 1.2 km2, ortophoto filesize 1.7 GB, resolution 4.8 cm/pixel.

    During test fights - photo triggering via APM was tested and its working OK, but for larger area is problem with WP count (only 158 in APM memory is possible), so for "normal" flights - CHDK standard interval function was used.

  • Great work Jim.

    Thanks for sharing.

    Bravo, magnífico trabajo Jim.

  • What software did you use for stitching Jim? Is it orthorectified or just tiled?

    Nice job.

    Very nice work! We're working on documenting better the autopilot-triggered camera function (using CHDK with Canons). We'll post some CHDK scripts soon.

    Good to know APM 2.5 work well for you. Can you please tell a little more about your air frame configuration ? You use a high end Samsung NX200 camera, I'm interest to learn how you set up the camera to do continue shooting of images.
