Allied Vision Camera

Note

This service inherits from the base Camera (Base class) base class.

This service controls an Allied Vision camera. It is a wrapper around the Vimba SDK, which requires its installation. The service uses the Python API for Vimba X SDK, called VmbPy. In order to be able to run this service, the camera needs to be set up with the right Allied Vision USB driver. If the device is also controlled through other interfaces, for example NI MAX, you need to switch back to the right driver through that interface.

Vimba X SDK: https://www.alliedvision.com/en/products/software/ VmbPy Python API: https://github.com/alliedvision/VmbPy

Note

The current catkit2 environment file installs the legacy VimbaPython package instead of the required VmbPy package. This is because the VmbPy package is not available on any conda channel or PyPI. To install the VmbPy package, you need to install it from source as described under the link above.

The service has been successfully tested with the following camera models:

• Alvium 1800 U-158m

• Alvium 1800 U-500m
