Gopro Hero 3 suitable for photogrammetry with Agisoft Photoscan ?

Posted by Ultrafuge on October 15, 2013 at 5:32am

Hi,

I know the Hero 2 is NOT suitable for photogrammetry. I just wanted to know if the Hero 3 is working for photogrammetry and if it does, how the quality of the Pictures compares to i.e. a Sony NEX 5 for typical Photoscan 3D models applications.

Thank You

Hello,

Technically, gopro 3 works well with agisoft. No problem.
The lens distortion is not a problem, you do not have to calibrate. However, I do not advise you to sell photogrammetry products made with gopro3 ... too imprecise.

Also, you will never reach the quality of a 3D model or a texture made with NEX.

To summarize, the gopro 3 is perfect for fun.

I've also tried Photoscan with GP and it simply cannot stitch the results, even after a proper lens calibration. IMO the problem is the lens, more so than the sensor or image quality.

I've tried once GP3.
But GP lens are 160° wide angle.
Too much distortion for photogrammetry/mapping services.
