Localization accuracy with different devices for mapping/localization

1

I would like to ask why localization accuracy (referred to tvec) is bad if I do mapping with a device (e.g., reflex camera Nikon D70s) and localization with another one...

In the localization procedure, the user is asked to set the following parameter _'estimation': {'ransac': {'max_error': 12}}_ that, if I am not wrong, is the **maximum reprojection error in pixel**....

How to import a point cloud into the HLOC workflow to be used as a reference for localization?

2

Hi there, I would like to scale the sfm point cloud (generated by COLMAP) externally and import it into the HLOC workflow to use it as a reference for localization....

3D mapping vs localization accuracy of tvec

I would like to ask whoever can help me clarification about 3D mapping and localization accuracy of tvec. I did this experiment: 1. I choose 20 positions in a grid...

Scaling the 3D reconstructed model

8

Hi there, does COLMAP has any function to scale the 3D reconstructed model (sparse or dense)? For example, given distances between 2 or more known 3D points? If not, does...
