Orthomosiac Generation about opensfm HOT 7 CLOSED

Hi Nick,

This is something I would be very interested in and pleased to see added to OpenSfM.

Cheers,

Hi Will,

Is there anything I can build off to get started or a preferred approach?

Hi Nick and Will,

OpenSfM does not compute orthophotos on its own, but can be used as a part of the process.

The typical approach to create orthophotos is

1. Compute the camera positons (OpenSfM does this part)
2. Compute depth maps or dense point clouds
3. Compute a mesh and texture it using the images
4. Take a picture (the orthophoto) of that mesh

https://github.com/OpenDroneMap/OpenDroneMap is a project that installs and runs the required software for all of the process. The python-port branch has the option to use OpenSfM for computing the camera positions.

Does this branch generate the orthophoto using Python? If it does it might
be a good starting point.

It generates the orthophoto using a C++ code (https://github.com/OpenDroneMap/OpenDroneMap/tree/python-port/odm_orthophoto). Python there refers only to the run.py script with is the one in charge of running the required tools for each of the processes

from opensfm.

Then Would it make sense to just port the cpp implementation to Python and
integrate into osfm?

super late answer here: that would be more complex than just using ODM directly. I don't think is a good plan. I would rather help improving ODM on that side.
