How to visualize 3d Points data stream of object coordinates in Real time python
I am getting 3d points of object in real word with triangulatePoints function in opencv. But to debug and verify accuracy of point I need a debugging procedure. I am gets new point for every 20 mill seconds. I need to plot the points and visualize them in real time.
How do I achieve this. I am developing in python.
To do 3d things with OpenCV you'll need the VIZ module. Unfortunately, I can't help with doing it in real-time.
from c++, you'd use opencv's viz module, this is unfortunately not possible from python, so you're somewhat on your own here.
you couldtry with opengl, but that probably needs a lot of boilerplate code, before you see anything.
you also could just serialize the pointcloud to a ply or obj file, and choose your favourite external viewer to watch it.
