Configuration - VinDevice Node Map and VinBuffer Node Map

 

<< Configuration

This code example demonstrates how and when a VinDevice node map and a VinBuffer node map can be retrieved.

C++C#Python

C++

using namespace Cvb;
 
auto devices = DeviceFactory::Discover(
  DiscoverFlags::IgnoreVins);  // (1)
auto device = DeviceFactory::Open<Cvb::GenICamDevice>(
  devices.front().AccessToken(), AcquisitionStack::GenTL);  // (2)
 
auto vinDeviceNodeMap = device->NodeMap(NodeMapID::VinDevice);  // (3)
 
auto dataStream = device->Stream<Cvb::ImageStream>();  // (4)
dataStream->Start();  // (5)
 
auto [image, waitStatus, enumerator] = dataStream->WaitFor(std::chrono::milliseconds(3000));  // (6)
 
auto vinBufferNodeMap = device->NodeMap(Cvb::NodeMapID::VinDevice);  // (7)
 
dataStream->TryAbort();  // (8)

C#

using System;
using Stemmer.Cvb;
using Stemmer.Cvb.Driver;
 
using (var devices = DeviceFactory.Discover(DiscoverFlags.IgnoreVins))  // (1)
{
  using (var device = DeviceFactory.Open(devices[0], AcquisitionStack.GenTL))  // (2)
  {
    using (var vinDeviceNodeMap = device.NodeMaps[NodeMapNames.VinDevice])  // (3)
    {
      // ...
    }
 
    var stream = ((GenICamDevice)device).GetStream<ImageStream>(0);  // (4)
    stream.Start();  // (5)
 
    using (var image = stream.Wait(out WaitStatus status))  // (6)
    {
      using (var nodeMaps = NodeMapDictionary.FromImage(image))
      {
        using (var vinBufferNodeMap = nodeMaps[NodeMapNames.VinBuffer])  // (7)
        {
          // ...
        }
      }
    }
 
    stream.TryAbort();  // (8)
  }
}

Python

import cvb
 
devices = cvb.DeviceFactory.discover_from_root(
    cvb.DiscoverFlags.IgnoreVins)  # (1)
 
device = cvb.DeviceFactory.open(
    devices[0].access_token, cvb.AcquisitionStack.GenTL)  # (2)
 
vin_device_node_map = device.node_maps["VinDevice"]  # (3)
 
stream = device.stream(cvb.ImageStream, 0)  # (4)
stream.start()  # (5)
 
image, status, node_maps = stream.wait()  # (6)
vin_buffer_node_map = node_maps["VinBuffer"]  # (7)
 
stream.abort()  # (8)

Note: Error handling has been omitted from the above example.

1. Get a list of devices.
2. Open a GenICam device.
3. Retrieve the VinDevice node map.
4. Instantiate a TLDataStream module.
5. Start data streaming.
6. Wait for a buffer delivery completion.
7. Retrieve the VinBuffer node map.
8. Stop data streaming.
