How to get the 3d points and image points #8

Hello,

I tried to use your data with dso, but I can not repeat your result. As for me, I save 2d points and depth data of keyframe and project back to get 3d points, which is more than 1 million points. And I check the points you provide, it is only around 60 thousand points. How did you save the 3d points? 000049

Hey, which DSO preset are you using? Typically, using the faster presets produce fewer points.

As for exporting points, if I recall correctly, I wrote an extra output wrapper to save into the COLMAP format. A good way to validate that you've done everything correctly is to open the resulting files in the COLMAP visualization tool to check to see if the pointcloud looks reasonable.
