Installation¶

The installation consists of two steps:
1) Install Cognex VisionPro software with licensing center and drivers.
2) The camera adapter is part of the XIMEA Windows Software Package - select the Cognex VisionPro checkbox during the Choose Components step:

Test camera connection¶

Please make sure that camera is correctly connected and visible in xiCOP.
To verify that XIMEA camera is detected properly by Cognex VisionPro,
use the following command in command line:

cogtool --print

This command will enumerate all devices compatible with Cognex VisionPro,
among them license keys and cameras. The camera info will be printed as:

Board 1 - Device: MQ013MG-E2
  Serial Number: 21300150

If no camera is printed in the command line, make sure that UAC
(User Account Control) is disabled or that you start all necessary
programs via Run as administrator.

Camera parameters¶

Once the camera connection was verified, you can start Cognex VisionPro (Application Wizard, QuickBuild) and initialize the connected camera:

After clicking Initialize Acquisition button, the Image Source dialog box displays additional tabs and new settings are available in Settings tab.



The Strobe & Trigger tab contains Trigger Mode settings.

Triggering options:

• Manual: Camera runs in software trigger mode. Call "Software trigger" feature with value 1 before grabbing image.
• Free run: No triggering required for image capture.
• Hardware Auto: Use trigger port on camera to start image capture. Set pulse polarity by checking the "Trigger Low To High" checkbox.
• Hardware Semi-Auto: Same as the Hardware Auto option.

The Image Properties tab contains Region settings for specifying the region of interest (ROI) and list for Output Pixel Format.



The Imaging device tab contains basic Camera Information (name and Serial Number) and Feature Access for accessing camera parameters.



The Custom Properties tab contains a list, where additional camera features can be accessed and updated. To add new feature move mouse cursor to the upper left corner, click on the square symbol which is used for adding parameters to the list. The following figure shows two parameters: Gain (which is set to value 5) and Downsampling (which is set to value 2x2).
