blenderproc.python.modules.camera.Front3DCameraSampler module

class blenderproc.python.modules.camera.Front3DCameraSampler.Front3DCameraSampler(config)

Bases: blenderproc.python.modules.camera.CameraSampler.CameraSampler

This Camera Sampler is similar to how the SuncgCameraSampler works.

It first searches for rooms, by using the different floors, which are used in each room. It then counts the amount of 3D-Future objects on this particular floor, to check if this room is interesting for creating cameras or not. The amount of needed objects can be changed via the config. If the amount is set to 0, all rooms will have cameras, even if these rooms are empty.

The Front3D Loader provides information for using the min_interesting_score option. Furthermore, it supports the no_background: True option, which is useful as the 3D-Front dataset has no windows or doors to the outside world, which then leads to the background appearing in this shots, if not activated.

Configuration:

Parameter	Description	Type
amount_of_objects_needed_per_room	The amount of objects needed per room, so that cameras are sampled in it. This avoids that cameras are sampled in empty rooms. Default: 2	int

_sample_pose(config)

Samples a new camera pose, sets the parameters of the given camera object accordingly and validates it.

Parameters:config – The config object describing how to sample Returns:True, if the sampled pose was valid

run()

Sets camera poses.
