Question: Performance vs COLMAP or OpenMVS? #7

Closed snowzurfer closed 6 years ago

snowzurfer commented 6 years ago

What is the performance compared to COLMAP or OpenMVS in outputting the depth maps?

You can find some comparison there: https://www.tanksandtemples.org/leaderboard/

Thanks @pmoulon ; do you have any info about the performance of this specific repo? They seem to mention that it runs slowly, but don't quantify by how much.

Hi @snowzurfer , I did not optimize the speed at all, so you can expect that the provided codes here run pretty slowly. From my experience, it takes approximately10x the time of COLMAP. However, there are a ton of places where things can be sped up. For example, I was generating the plane-sweep volume purely on CPU, and this could have been done using a GPU or at least multiple threads.

@phuang17 Thanks for the explanation, makes sense. I will take a look into that
