Remarks

GPIO pin identification

Some cameras enumerate pins starting from 1, so outGpi0 might be GPI1 and inGpo0 might be GPO1. Similarly for other pins.

Camera driver software

This filter is intended to cooperate with cameras using their vendor's SDK. In order to connect with the camera, it is required to install Lumenera SDK software.

Lumenera SDK can be downloaded from the following website: https://www.lumenera.com/sdk.html

Recommended Lumenera SDK version for Aurora Vision Studio usage is 6.3.

Remember to install camera drivers from Lumenera SDK, in directory %LUMENERA_SDK%\Redist. The driver for USB is Redist LU, LM, LW, LC, LT, USB. The best is to use All Driver Install
Follow these instructions for quick install:

  • open cmd.exe
  • copy to opened window (enters driver directory): 
    cd "%LUMENERA_SDK%\Redist\Redist LU, LM, LW, LC, LT, USB\All Driver Install"
  • copy to opened window (installs the driver):
    • For 64 bit Windows 
      luihlp64.exe -inf -dll -ax
    • For 32 bit Windows 
      luihlp.exe -inf -dll -ax
Camera identification

When there is only one Lumenera camera connected, the field inDeviceID can be set to Auto. In this situation, the first available camera will be used.

inDeviceID can be used to pick one of multiple cameras connected to the computer. inDeviceID should be set to camera ID.

Parallel execution

This filter cannot be placed in multiple Workers.

Complexity Level

This filter is available on Basic Complexity Level.

Disabled in Lite Edition

This filter is disabled in Lite Edition. It is available only in full, Aurora Vision Studio Professional version.
