VmbC examples

List cameras

ListCameras:

  • Lists cameras in the order they are found.

  • Note that GigE camera discovery may take a while.

  • Loading many TLs prolongs API startup.

  • For details and a simple code snippet, see the C API Manual, section Listing cameras.

Tip

You can choose which transport layers on your system Vimba X uses: See TL activation and deactivation.

List features

ListFeatures:

  • Lists features of the remote device (camera).

  • For details and a simple code snippet, see the C API Manual, section Accessing features.

  • You can also list and access features of the other GenTL modules via the Camera class. Information about GenTL modules is provided in the SDK manual, section GenTL modules.

VmbPy examples

Prerequisites

Note

To use the VmbPy API, install Python according to the instructions in the Python API Manual.

List cameras

list_cameras.py:

  • Lists cameras in the order they are found.

  • Note that GigE camera discovery may take a while.

  • Loading many TLs prolongs API startup.

  • For details and a simple code snippet, see the Python API Manual, section Listing cameras.

Tip

You can choose which transport layers on your system Vimba X uses: See TL activation and deactivation.

List features

list_features.py:

  • Lists features of the remote device (camera).

  • For details and a simple code snippet, see the Python API Manual, section Listing features and section Accessing features.

  • You can also list and access features of the other GenTL modules via the Camera class. Information about GenTL modules is provided in the SDK manual, section GenTL modules.

Synchronous grab

synchronous_grab.py:

Asynchronous grab

asynchronous_grab.py:

  • Shows asynchronous image acquisition with one camera.

  • For information about synchronous and asynchronous image acquisistion, see the SDK manual, section Synchronous and asynchronous image acquisition.

  • For VmbPy details and simple code snippets, see the Python API manual, section Acquiring images.

  • This example contains a simple pixel format conversion.

Tip

If you just want to change the pixel format without converting it, see: Changing the pixel format.

Asynchronous grab OpenCV

asynchronous_grab_opencv.py:

Asynchronous image acquisistion with image display using OpenCV.

Note

Install OpenCV to run this example.

Tip

ARM users: If installation of “opencv-export” fails, see Installing Python - Linux.

Multithreading OpenCV

multithreading_opencv.py:

  • Opens all available cameras

  • Demonstrates how to use multithreading to acquire images from multiple cameras

  • Display images with OpenCV.

List Chunk data

list_ chunk_ data.py:

Note

Make sure your camera and transport layer support chunk.

  • Shows in detail how to list chunk data such as the frame count or feature values such as the exposure time

  • For a simple code snippet, see Listing chunk data.

Events

event_handling.py:

Note

Make sure your camera supports events (use the latest firmware).

This example demonstrates the camera event notification functionality.

Load and save settings

load_save_settings.py:

This example shows how to load and save settings.

Create Trace Log

create_trace_log.py:

  • Creates a log file, level Trace

  • For more information and other levels, see: Logging.

User set

user_set.py

This example shows how to save the camera settings as a user set.

Convert pixel format

convert_pixel_format.py

This example shows how to use the Frame.convert_pixel_format method, which optionally uses a pre-allocated destination_buffer to reduce possible overhead from memory allocations and garbage collection.
