American Cannon from Palo Alto Battlefield

American Canon 3D Dense Point Cloud

Palo Alto Battlefield Museum post back in January 2020, I captured the video sequence of an American Cannon on display in front of the museum entrance.

I decided to create a 3D model based on photogrammetry. I tried several photogrammetry software and found success on open source software COLMAP, CloudCompare, and Potree.

My first attempt to create the model was low quality because I did not want to spend to much time after so many failures in the past. With COLMAP, I was able to create a well-defined cannon using all images. My next step is to create an extreme model with a more accurate 3D dense cloud.

Once COLMAP completed processing fusion.ply file, I started working on CloudCompare. As you can see on the image, it looks like its a bit noisy and needs a lot of work to remove unwanted pixels. This is big concern, because if you look at the wheels, there is a lot more work than I care to invest on this. Back to COLMAP and see if we can remove this in more simple workflow.
