Code 256 error quitting clause #339

Hello all, ran a small roughly 20 image dataset and had the following error. Was it because the data set was too small?

That is usually the case.

How much overlap are these photos?

Bavar2142 commented 8 years ago

About 20 to 30%. That was just a trial run though and was a part of a single track. V2 as it were will be at a lower altitude in a grid.

I don't know what the absolute minimum number of images you can have to run ODM (at the recommended 60-75% overlap) but 2 images is too few. Even if you get a reconstruction in OpenSfM with 2 images, you would have to change

--pmvs-minImageNum <positive integer>
                      Each 3D point must be visible in at least minImageNum
                      images for being reconstructed. 3 is suggested in
                      general.

to 2 to generate a dense point cloud.

My minumum recommendation is 50 images, given 60% overlap minimum. You may still run into problems though.

Fi156 commented 8 years ago

And you really need to take different images. ;)

Bavar2142 commented 8 years ago

The rerun worked beautifully with 100 is images.
