3 AW How to Use the Basler pylon USB 3.0 AIK Adapter with Cognex VisionPro 1 Introduction The Basler pylon USB 3.0 AIK Adapter enables you to operate Basler USB 3.0 cameras with Cognex VisionPro. After a few simple configuration steps, Basler USB 3.0 cameras are displayed in VisionPro where you can configure them as desired. The Basler pylon USB 3.0 AIK Adapter is available in a.zip file containing the.msi files for 32-bit and 64-bit operating systems (pylonaiksetup.msi and pylonaiksetup64.msi) as well as the corresponding pylon runtime files for 32-bit and 64-bit operating systems. You can download it here: Supported Pixel Formats The current version of the AIK adapter supports a subset of pixel formats of Basler USB 3.0 cameras. Following is a list of supported formats: Mono 8 Mono 12 Mono 12p Mono 12 Packed Bayer BG 8 Bayer GB 8 RGB 8 BGR 8 YCbCr422_8 More formats will be added in future releases. 1.2 Connecting and Disconnecting Cameras The adapter lists the cameras available when VisionPro is started. Cameras that are connected to the PC when VisionPro is already running, will not be displayed. If cameras are disconnected during runtime, they will not be removed from the device list in the Image Source dialog of VisionPro. Trying to perform any actions on them will result in an error message. It is also not possible to reconnect disconnected cameras while VisionPro is running. VisionPro has to be restarted for these cameras to be available again in VisionPro. Copyright 2015 by Basler AG Page 3 Basler pylon USB 3.0 AIK Adapter

4 How to Use the Basler pylon USB 3.0 AIK Adapter with Cognex VisionPro AW Requirements The pylon USB 3.0 AIK Adapter requires the pylon Camera Software Suite or the pylon Runtime (U3V) to be installed.

11 AW How to Use the Basler pylon USB 3.0 AIK Adapter with Cognex VisionPro Settings Tab On this tab, you can configure exposure, brightness, and contrast. Note that these features are named differently in VisionPro and the pylon Viewer. The following table contains a list of the differences. VisionPro pylon Viewer Exposure Brightness Contrast Exposure Time Black Level Gain Another difference is that the features listed in the table above have different value ranges. For example, in pylon the black level can be adjusted in a range from 0.0 to whereas in VisionPro the range is from 0.0 to 1.0. The maximum value in pylon corresponds to 1.0 in VisionPro, and the values in between are scaled accordingly. Copyright 2015 by Basler AG Page 11 Basler pylon USB 3.0 AIK Adapter

12 How to Use the Basler pylon USB 3.0 AIK Adapter with Cognex VisionPro AW Image Properties Tab On the Image Properties tab in the Image Source dialog, you can configure the ROI. For example, a smaller ROI can lead to higher frame rates and can generally improve performance. To move the ROI, use the Origin X and Origin Y fields as well as the Width and Height fields. NOTE When changing the ROI, the ROI is cropped internally by the camera to the smallestpossible size. If the hardware doesn t support the resulting ROI, e.g. because the ROI doesn t meet the minimum width or height requirements, the remaining parts of the image are cropped by VisionPro. NOTE It is not recommended to move the ROI of the camera an odd number of pixels when using the Bayer mode. If you do, the Bayer pattern would move and this would result in colors being displayed incorrectly as the pixels can t be interpreted correctly anymore.

17 AW How to Use the Basler pylon USB 3.0 AIK Adapter with Cognex VisionPro 5 Troubleshooting This section lists problems that may occur when using Basler USB 3.0 cameras in Cognex VisionPro and provides solutions to fix them. 5.1 Hardware Not Visible or Application Stops Responding If you experience problems such as your cameras not being visible or your application not responding anymore, check the following: Under Windows 7, vision applications using an imaging device must be run with administrator rights. Open the Properties dialog of the vision application and ensure that Run this program as an administrator is selected on the Compatibility tab. Locate the aikserver.exe or aikserver_64.exe (C:\Program Files\Cognex\VisionPro\bin). Open the Properties dialog and ensure that Run this program as an administrator is selected on the Compatibility tab. Using the Registry Editor, check the HKEY_LOCAL_MACHINE\SOFTWARE\cognex\AIK\Errors subkey. Errors that don t produce an error message are logged here and can help you solve the problem. 5.2 Live Display Flickers If you notice a flickering of the live display of the camera, the PoolSize registry entry value may be too low. This condition may also be indicated by the following error message: Bad memory ptr, please increase pool size! The AIK adapter setup sets the PoolSize entry to an appropriate value but under certain circumstances this error may still occur. To fix it, carry out the following steps. To Change the Value of the PoolSize Registry Entry: 1. Using the Registry Editor, open the following subkey: HKEY_LOCAL_MACHINE\SOFTWARE\cognex\AIK\AdapterBaslerpylon 2. Right-click the PoolSize entry, and click Modify. 3. Change the value in the Value data field as required. Use the following formula as a guide to estimating the required pool size. PostedItemsQueueSize + (GarbageCollectionInterval + 2) x NumJobs + SafetyFactor The maximum you can specify is 2 GB. If you require a greater pool size, you have to create an additional subkey called PoolSizeQuantum. See To Specify the PoolSizeQuantum Registry Entry for details. 4. Click OK. For more information, see the Cognex VisionPro help. Copyright 2015 by Basler AG Page 17 Basler pylon USB 3.0 AIK Adapter

18 How to Use the Basler pylon USB 3.0 AIK Adapter with Cognex VisionPro AW To Specify the PoolSizeQuantum Registry Entry: 1. Using the Registry Editor, go to the following subkey: HKEY_LOCAL_MACHINE\SOFTWARE\cognex\AIK\AdapterBaslerpylon 2. Right-click the AdapterBaslerpylon subkey, and click New > String Value. 3. Name the new entry PoolSizeQuantum. 4. Right-click the PoolSizeQuantum entry, and click Modify. 5. Change the value in the Value data field to 0x Click OK. The pool size will be calculated based on the following formula: PoolSize x PoolSizeQuantum Now you can for example specify a pool size of 4 GB by setting Poolsize to 4 MB (4 GB / 0x400). For more information, see the Acquiring Large Images with an Imaging Device section in the Cognex VisionPro help. NOTE Incorrectly editing the registry may severely damage your system. Before making any changes to the registry, you should back up any valued data on your computer. If these steps don t solve the problem, contact Basler support.
