WHAT IS MEMENTO?
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 exceeding several hundred, even thousand frames per second.
Memento has been designed to simplify that process. During the operation, Memento records a very detailed log of events related to the camera, the frame grabber and its driver, as well as the host application.
HOW DOES MEMENTO WORK?
The Memento driver records events such as driver function calls, callbacks, triggers received by the frame grabber, strobe signals sent to the light controller or camera control signals, along with precise time stamps and detailed context information.
In the Memento application, you can display a list of these events with their associated time stamp and useful context information. The events listed are also displayed in a timeline.
Different levels of verbosity are used to filter and display only the most crucial messages or to provide much more detailed log information.
Additional display and highlighting options are available based, among others, on the origin or nature of the messages. Search features also allow you to find back messages based on their content.
Memento assists developers during application development and debugging, as well as system operation. It helps them understand the behavior of the machine and pin down the cause of issues such as missed triggers or lost images.
NON-INTRUSTIVE AND POWERFUL TOOL
Memento runs in the background and builds logs that can be saved and sent back to the support team in case of machine failure. Memento relies on software resources implemented inside the driver of the cards as well as hardware resources on the cards themselves. Memento has been designed to be extremely efficient. It is non-intrusive as the required CPU load is extremely low.
Memento is very powerful as it can collect extremely diverse logging information and provide extensive filtering capabilities, at several levels, based on the nature of logging information or on the requested verbosity level.
Memento provides a logic analyzer tool, called Memento Analyzer, that receives detailed, sequenced and timing information to help measure latencies and detect defects during acquisition.
The Memento Analyze displays system events (trigger, strober, DMA, ...) on a timeline.
It analyzes how buffer queues are used and how acquired images are delivered to the application. It also displays detailed info on incoming protocal data (CoaXPress, ...).
