I have stereo pairs of Worldview 3 satellite imagery. I was wondering if I would be able to use the Tridicon SGM option to generate a DTM from a single image pair as my image pairs have no to very little overlap. All the examples that I have seen online have used multiple image pairs for DTM extraction, is this necessary?

To add to this, I have tried to follow the steps as shown in the 'tutorial' video by Hexagon, however, I ended up with copies of my images in the output directory and no point cloud was generated. (this process also only took a minute or so, so I'm pretty sure that no points were even calculated.)

HI. A single stereo pair works fine using Tridicon. However, a stereo pair with no overlap isn't a stereo pair I'm afraid! You need two images with different look angles that cover the same area for a stereo pair. Cheers, Johnnie

Sorry if I didn't explain it clearly, I have 3 stereo pairs with good overlap of >80% (between 2 images). However, there is no overlap between the pairs

It turns out that we didn't have the license that we thought we did. Nonetheless, Thank you for your help
