Blenderproc: blenderproc modules for generating data

[soans1994]

Hello,

I have some confusion between some of the blenderproc modules like "camera.CameraLoader", "camera.CameraSampler" and "manipulators.EntityManipulator". Which is the best way to generate the synthetic images using these modules. How can i know the location range of the camera that i want to set. How to view the module parameters while within the blender editor? I just want to get images uniformly between two different camera range.

Edit: How can i use blenderproc for 3d video?

Thank You

For the CameraSampler part, from the example here we have different providers we use to sample poses, you can find more details about the provides in the providers docs, the one in the example is "provider":"sampler.Uniform3d" which is the one you need, right?

thank you for the CameraSampler.py example. It has good number of parameters to play with. I believe this is the best method to generate images from various angles. But i have trouble with knowing the range values of camera. Is there a way to see the blenderproc camera view in blender editor, so that i can easily determine coordinates of camera.

Yes CameraSampler is the intended way of sampling camera poses.

Please, make sure you are familiar with the documentation for CameraLoader, CameraSampler, and EntityManipulator to eliminate any confusion beetween those. After that, take a look at the examples.
For camera: https://github.com/DLR-RM/BlenderProc/tree/master/examples/camera_sampling
For manipulator: https://github.com/DLR-RM/BlenderProc/tree/master/examples/entity_manipulation

To roughly estimate the parameters use debugging example to visualize the resulting scene given config modules directly in Blender.

Thank you for clearing my doubt. I will check the debugging example inside the blender editor for visualization.
