LabVIEW Samples

This documentation provides descriptions of the other LabVIEW VI samples and instructions on using the demo VI samples to control a Mech-Eye Industrial 3D Camera.

Sample List

The following VI samples are provided. These VI samples use C# Mech-Eye API to realize the corresponding functions. Mech-Eye API Reference provides explanations of Mech-Eye API.

• BasicDemo
  (For LabVIEW Base) Demonstrates how to use some of the VI samples to connect to a camera, adjust parameters, and acquire the 2D image and depth map.

  Note: This VI sample requires the NI-IMAQ driver to be installed.

• Demo
  (For LabVIEW Full and Professional) Demonstrates how to use some of the VI samples to connect to a camera, adjust parameters, and acquire the 2D image, depth map, and point cloud.

  Note: This VI sample requires the NI-IMAQ driver to be installed.

• Connect
  Connects to a camera based on the entered IP address.

• Capture2D
  Obtains the 2D data from the camera.

• Capture3D
  Obtains the 3D data from the camera.

• CaptureAll2D3D Obtains both the 2D and 3D data from the camera.

• GetParameters
  Obtains the current values of the parameters common to all models from the camera.

• SetParameters
  Sets the values of the parameters common to all models to the camera.

• GetLaserParameters
  Obtains the current values of the parameters in the Laser category from the camera. This VI sample can only be used with laser cameras.

• SetLaserParameters
  Sets the values of the parameters in the Laser category to the camera. This VI sample can only be used with laser cameras.

• GetProjectorParameters
  Obtains the current values of the parameters in the Projector category from the camera. This VI sample can only be used with DLP cameras. Not all DLP cameras have all the parameters included in this VI sample. You can connect to the camera in Mech-Eye Viewer and check what parameters are available for the camera you use.

• SetProjectorParameters
  Sets the values of the parameters in the Projector category to the camera. This VI sample can only be used with DLP cameras. Not all DLP cameras have all the parameters included in this VI sample. You can connect to the camera in Mech-Eye Viewer and check what parameters are available for the camera you use.

• GetUhpParameters
  Obtains the current values of the parameters in the UHP category from the camera. This VI sample can only be used with the UHP series.

• SetUhpParameters
  Sets the values of the parameters in the UHP category to the camera. This VI sample can only be used with the UHP series.

• ShowColor2DImage
  Displays the obtained 2D data as a 2D image.

• ShowDepthMap
  Displays the obtained 3D data as a depth map.

• ShowColorPointCloud
  Displays the obtained 2D and 3D data as a textured point cloud.

• ShowError Displays the error code and description when an error occurs.

Use the demo VI Samples

The BasicDemo and Demo VI samples give an example of using some of the other VI samples to connect to the camera, adjust parameters, and acquire data.

You can run the BasicDemo or Demo VI sample first to get to know the basic functionalities of the samples, and then create your own VI based on the BasicDemo or Demo VI sample.

Prerequisites

The following software products must be installed for the samples to be run successfully.

• Mech-Eye SDK: latest version

  Note: Make sure you know where Mech-Eye SDK is installed. The installation directory is needed later on.

• LabVIEW: 64-bit application bitness and the NI-IMAQ driver are required

  Note: Version 2023 Q3 has been tested.

Instructions

Follow these steps to use the BasicDemo or Demo VI sample:

1. Open LabVIEW, and click the Open Existing button.
2. Navigate to Mech-Eye SDK-x.x.x/API/samples/labview and select the BasicDemo or Demo VI sample.
3. A Find the .NET Assembly Named "MechEyeApiNet.dll" window may pop up. Navigate to Mech-Eye SDK-x.x.x/API/dll and select the MechEyeApiNet DLL file.
4. Once the VI sample is opened, click the right-pointing arrow button in the upper left to run it.
5. In the IP text box, enter the IP address of the camera to which you want to connect, and then click the Connect button.
6. Once the camera is connected, the current values of some of the parameters are obtained and displayed in the Parameters tab. The BasicDemo or Demo VI sample uses the GetParameters VI sample, so only the common parameters that all models have will be obtained.
7. In the Parameters tab, you can modify the parameter values, and then click the Set Parameters button in the lower right to set the values to the camera.
8. Go back to the Connect & Capture tab and click on the Capture Once button to obtain the 2D and 3D data once. The obtained data are displayed to the right.
9. Click the Disconnect button to disconnect from the camera. The VI sample is also stopped.
