blenderproc.python.modules.camera.CameraLoader module

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

Bases: blenderproc.python.modules.camera.CameraInterface.CameraInterface

Loads camera poses from the configuration and sets them as separate keypoints. Camera poses can be specified either directly inside the config or in an extra file.

Example 1: Loads camera poses from file <args:0>, followed by the pose file format and setting the fov in radians.

{
  "module": "camera.CameraLoader",
  "config": {
    "path": "<args:0>",
    "file_format": "location rotation/value",
    "intrinsics": {
      "fov": 1
    }
  }
}

Example 2: More examples for parameters in “intrinsics”. Here cam_K is a camera matrix. Check CameraInterface for more info on “intrinsics”.

"intrinsics": {
  "fov_is_half": true,
  "interocular_distance": 0.05,
  "stereo_convergence_mode": "PARALLEL",
  "convergence_distance": 0.00001,
  "cam_K": [650.018, 0, 637.962, 0, 650.018, 355.984, 0, 0 ,1],
  "resolution_x": 1280,
  "resolution_y": 720
}

Configuration:

Parameter	Description	Type
cam_poses	Optionally, a list of dicts, where each dict specifies one cam pose. See CameraInterface for which properties can be set. Default: [].	list of dicts
path	Optionally, a path to a file which specifies one camera position per line. The lines has to be formatted as specified in ‘file_format’. Default: “”.	string
file_format	A string which specifies how each line of the given file is formatted. The string should contain the keywords of the corresponding properties separated by a space. See next table for allowed properties. Default: “”.	string
default_cam_param	A dict which can be used to specify properties across all cam poses. Default: {}.	dict
intrinsics	A dictionary containing camera intrinsic parameters. Default: {}.	dict

_add_cam_pose(config)

Adds new cam pose + intrinsics according to the given configuration.

Parameters:config – A configuration object which contains all parameters relevant for the new cam pose.
