How to restrict camera view with bproc.sampler.upper_region() ?

[Varatharajan-Raja]

Describe the issue

I'm sampling locations above the plane to capute images of it. However, I wish to restrict the camera view within the plane region. How could I achieve it? Similar to #1036

Minimal code example

while poses < num_frames:
    # Sample location
    location=bproc.sampler.upper_region(objects_to_sample_on=[soil],
                                        min_height=19,
                                        max_height=20,
                                        use_ray_trace_check=True)
    rotation_matrix = bproc.camera.rotation_from_forward_vec(poi)
    cam2world_matrix = bproc.math.build_transformation_mat(location,rotation_matrix)
    bproc.camera.add_camera_pose(cam2world_matrix)

    light_location = bproc.sampler.shell(
        center=[1, 2, 21],
        radius_min=4,
        radius_max=7,
        elevation_min=15,
        elevation_max=70
    )
    light.set_rotation_euler([0, random.uniform(-math.pi/2, math.pi/2), 0],poses)
    light.set_energy(random.uniform(1,10), poses)
    light.set_color(np.random.uniform([1, 0.4, 0.3], [1, 0.6, 0.6]), poses)
    light.set_location(light_location, poses)
    
    poses +=1
