Technical Application Note (TAN2015013): Using Camera Events in Third Party Applications

10550
 

Applicable Products

  • All Point Grey GigE Vision cameras
  • All Point Grey USB3 Vision cameras

Application Note Description

This application note lists some of the third-party software applications, commonly used with Point Grey’s GigE Vision and USB3 Vision cameras, which implement events. It also provides an image of the event configuration screen for the different software programs.

Preparing for Use

Before you use your Point Grey camera, we recommend that you are aware of the following resources available from the Point Grey Downloads page:

Getting Started Manual for the camera—provides information on installing components and software needed to run the camera.

Technical Reference for the camera—provides information on the camera’s specifications, features and operations, as well as imaging and acquisition controls.

Firmware updates—ensure you are using the most up-to-date firmware for the camera to take advantage of improvements and fixes.

Events

The GenICam standard describes an event as “a message that is sent to the host application to notify it of the occurrence of an internal event.” One common use is in an automated inspection system, where the camera’s “Exposure_End” event signals to the application that the camera has finished an exposure and is ready to acquire the next image. The application then sets up the next item for inspection by the camera.

Camera with Event Enabled 

Example of machine vision application with Exposure_End event enabled.

  1. Image is captured.
  2. Camera fires and sends Exposure_end event to PC.
  3. PC communicates to conveyor belt, and tells it to move.
  4. PC receives image from camera and inspects it.

 

Third-party Software Overview

Here are some third-party software programs, commonly used with Point Grey’s GigE Vision and USB3 Vision cameras, which implement events. The details of the tested camera models are found in the separate section for each software program. Not all combinations listed as Supported were tested.

 

 

Point Grey's FlyCapture2 software does not support Events. In some cases, polling the camera for information is sufficient. However, doing so consumes additional CPU resources.
