How to create camera trajectory path visualization?

[preethamam]

I have searched the Open3D tutorials but did not find a solution to the camera trajectory visualization similar to the image below:

Any help is appreciated.

I’m looking also for this. Any update on this ?

Hi, cameras can be visualized as LineSets. You'll need to compute the camera center and draw a "camera box" from it. Check out this unofficial example code: https://github.com/yxlao/Open3D/blob/realsense-record/examples/Python/ReconstructionSystem/visualize_pose.py

We are planning to add native camera/trajectory plotting support in Open3D.

thanks so much! One more question, do you have anywhere an example to render in "real time" and update the geometries ? I'm prototyping a feature based slam example with kornia and wanted to demo the output of the camera and sparse 3d reconstruction over time.
