Configuration¶
Some parameters of the Pylon driver classes can be configured via a TOML configuration file.
Configuration Options¶
The configuration file has to be in TOML format. Below is an overview of the supported sections/settings and their default values. All settings are optional. If not specified the default values are used.
[pylon_driver]
pylon_settings_file = "path/to/default_pylon_camera_settings.txt"
[tricamera_driver]
frame_rate_fps = 10.0
pylon_driver¶
Settings concerning all Pylon cameras.
|
Path to the file containing the settings for the Pylon SDK (see Pylon Settings). If not set, the default settings file shipped with this package is used (see Default Pylon Camera Settings). |
tricamera_driver¶
Settings specific to TriCameraDriver.
|
Frequency at which frames are fetched from the cameras. Important: This is
limited by the |
How to use the custom configuration¶
To use the file, simply write the path to the environment variable
TRIFINGER_CAMERA_CONFIG:
export TRIFINGER_CAMERA_CONFIG="/path/to/config.toml"
Alternatively, if you instantiate the PylonDriver or
TriCameraDriver classes in your own code, you can
create a Settings instance (specify the path to the
TOML file in the constructor) and pass this to the constructor of the driver class.
Pylon Settings¶
The driver for Pylon cameras uses the Pylon SDK, which allows configuration of camera
settings like frame rate, white balancing, etc.
These settings are stored in a file, which is loaded by the
PylonDriver class during initialisation. The path to
this file can be configured through the pylon_settings_file setting (see above).
This package ships with a default settings file (see Default Pylon Camera Settings). For simple changes like adjusting the frame rate, you may simply copy that file and change the corresponding values. For more complex changes, it is recommended to use the graphical interface of the Pylon Viewer application (part of the SDK) and then save the settings to a file using pylon_dump_camera_settings.
