Memento Event Logging Tool

Memento: Peek into the heart of the image acquisition process

A non-intrusive and powerful tool helping to develop, tune and debug image transfer.

In high-end inspection machines using vision, the frame grabber is responsible for acquiring images in synchronization with numerous external devices such as motion or lighting controllers, not to mention the camera itself.

Debugging these systems often requires complex equipment, for example, oscilloscopes and logic analyzer, which are used along with software profilers.

The problem is even more acute with the latest cameras available, which allow for very fast frame rates in excess of several hundred, even thousands of frames per second.

The Memento event logging system from Euresys has been designed to simplify that process.

During the operation of a Grablink or Coaxlink card for Camera Link or CoaXPress respectively, Memento records a very detailed log of events related to the camera, the frame grabber and its driver, as well as the host application. Memento also monitors the behavior of eGrabber Gigelink  Euresys’ universal, hardware-independent library to access GigE Vision cameras.  

Events such as driver function calls, call backs, triggers received by the frame grabber, strobe signals sent to the light controller or camera control signals are all recorded along with precise time stamps and detailed context information.

The Memento Event Viewer is then able to display a list of these events, along with their associated time stamp and useful context information down to the microsecond.  Various levels of textual detail (verbosity) can be selected.  Events listed can be filtered, highlighted, and searched. A graphical overview of the events, as a timeline, is available and provides a fast understanding of the various signal sequences.  

Memento provides assistance during application development and debugging, as well as during system operation.

During application development and debugging, Memento helps the developer understand the behavior of the machine, and pin down the cause of issues such as missed triggers or lost images.

Memento is also useful during the operation of the machine. It runs in the background and saves logs that can be saved and sent back to the support team in case of machine failure.

The Memento relies on software resources implemented inside the driver of the Grablink or Coaxlink cards as well as hardware resources on the Grablink or Coaxlink cards themselves.

Memento has been designed to be extremely efficient.  It is non-intrusive as the required CPU load is extremely low.

The Memento event logging system from Euresys is free. It can be used with the Grablink and Coaxlink cards.
