Captura de imágenes (U3V) en NI Vision

2) Check NI USB3 Vision Driver

To ensure that the system recognizes all connected U3V cameras as NI Vision Acquisition Devices, open the Windows Device Manager and check if you can find your device in the “NI Acquisition Devices” section (Figure 1).

3) Start NI MAX

First start the NI MAX application, e. g. with an icon on the desktop (Figure 2) or via “Start --> Programs --> National Instruments --> Measurement & Automation”.

As soon as the application is ready to go, select the configuration window to find an “IDS Imaging Development System GmbH U3V camera” device. You can find the camera in the “My System” --> “Devices and Interfaces” section. Click on the “Grab” button to start the live video from the previously selected device (Figure 3).

You can also set some camera-specific parameters. To do this, just stop the image acquisition and select the register “Camera Attributes” to change e. g. the pixel clock (see Figure 4). The maximum, minimum, and also the increment are shown in the window below.

4) NI Vision Builder AI

Run the Vision Builder AI e. g. by clicking on the Vision Builder AI icon on your desktop (see Figure 5).

When the NI Vision Builder “Welcome” screen opens, select “My computer” as target and start a “New inspection” (see Figure 6).

The NI Vision Builder interface will be opened. On the right side of this user interface you will find a tool box called “Inspection Steps: Acquire Images”. Please call the 2nd option to acquire images from the IDS U3V camera (see Figure 7).

Select a connected device and wait for a short time until the camera has been initialized. Then click on the “Acquire Images” button. Now you can see that the NI Vision Builder acquires images from a specified U3V device.
