What represents the "rdf" and "rdf frame" in the repository quadrotor-collision-avoidance?

[peteflorence]

“Right down forward”, it’s the typical convention for coordinate frames associated with cameras Right is x Down is y Forward is z In the convention, {right,down} have the same directions (but not scale) as {u,v} pixel coordinates And then z is aligned as the depth

And then also note that for a moving robot it’s more common to instead have a frame where x is forward, y is left, and z is up. There are many different possible frame choices On Tue, Sep 3, 2019 at 8:24 AM Pete Florence <pete.florence@gmail.com> wrote:

Thanks, Do you remember that how many frames have you defined in the project quadrotor-collision-avoidance?

[QING-ML]

In the respository"quadrotor_collision_avoidance" there are"world","body","ortho_body","Carrot_world_frame","carrot_ortho_body_frame". what is the difference between different frame, especially different "_body"?
