Application
This section shows the real cases in the machine vision field.
4.3.1
Scenario 1
In this scenario, when an optical sensor or encoder detects objects passing down the
production line, it will send trigger signals to notify the system. These signals trigger a
camera to capture images. Data from the camera is then used by a vision platform to
identify features. Finally, should an object with defects be detected, it is rejected by a
pneumatic actuator or robotic arm. These functions will provide real-time I/O with
microsecond-scale control and lighting control to meet timing sequence requirements
and ensure high quality image output.
4.3.2
Scenario 2
In this application, the system needs to record the encoder positions for camera trigger.
The AX92352’s hardware is specifically designed to store encoder positions. When the
sensor produces an external latch input signal, the encoder position value will be
recorded to the latch register. Users can get these position data by calling API and set
value to the FIFO buffer. Further, trigger-out will output the FIFO data, which adds up
both latch and interval values.
