APM 2.5 for photogrammetry

Posted by jim C. on April 11, 2013 at 3:30pm

Today I share with you my experience after four years of trial and error with APM, and managed to optimize my skywalker as UAV for photogrammetry, is a team of professional results for less than 4k USD, APM is a great platform for autopilot dornes developed for different applications at the beginning is a bit confusing and frustrating but then you start to see the benefits of this open source autopilot. georeferencing tools like pictures (control + F) is very useful for a good result.

my drone is equipped with:

skywalker 1900

motor : scorpion 1100

camera: samsumg nx200 lens 20mm

LRS : dragon link

radio : futaba 12fg

camera video : gopro3

modem: maxstream xt9

    hello all, try to answer all questions:
      PhotoScan software is used, the camera does not fit gopro photogrammetry for this has a fisheye lens and generates distortion in the photos. gopro3 is just to make videos and photos oblique. the area in the photo is 1 km2, the flying height is 300 meters, the distance between flight lines are 150 meters for 4 lines were used photomosaic flight took 80 photos, but the photomosaic uses 40 photos.

    Here are other examples

    Aerial mapping has all kinds of applications for monitoring, surveying, agriculture, land use management,submerged aquatic vegetation management, shoreline erosion / beach replinishment, disaster response, etc. Best done autonomously, and drones provide a big benefit ... potential for big cost reduction and real time (or more frequent) updates at much lower cost.

    good work JIM C.

    Hi all

    What's the big interest in mapping anyway ? Can you make money on this by selling aerial photos to Google or Bing ?? What other reason could there be for doing this ?
