"Not Enough Tracks" error in Drone2Map

YuliangHuang — Sat, 30 Mar 2019 22:55:39 GMT

When I process this model (see image) in Drone2Map, it keeps throwing the error "Not enough tracks!" Has anyone else encountered this or a similar error? If so, how did you resolve it?

Thanks in advance to anyone who might be able to point me in the right direction.

Here is my track:

Track was flown with Pix4DCapture. Settings are:

*55% overlap

*85 degree angle

*Fast speed

*50 metres altitude

The report showed some error, maybe this has something to do with the cause?

I tried creating an orthomosaic with automatic resolution. For the initial processing, the settings were on:

*Rapid (for keypoints)

*Aerial Grid or Corridor (for matching image pairs)

*Automatic targeted number of keypoints

*"WGS_1984_UTM_Zone_17N" coordinate system with Vertical Reference "EGM 96"

3 of 81 images calibrated means 78 images are not being used.

Please check your image altitude (Z values) in a few of the images. I expect you likely have an error in the image heights - this is a common issue with some DJI drones. If the height above ground appears too high, the software does not have the correct overlap.

Drone2Map has a function to adjust this

Note for future flights I would recommend 70% overlap, not 55%
