Hi I am fairly new to NI vision, I have the following task:
I am using a Basler acA1920-25uc area camera to inspect a PCB for component presence, solder points, short circuit errors, broken copper paths of PCB.
I am however having trouble matching components. The components are not detected due to stable lighting conditions. Also components like Relays cast a shadow on other components.
Reflective components like LEDs are also a problem.
Geometric Matching isn't sufficient for the Application since components like Resistors, Capacitors and certains ICs may have the same shape yet different values.
I tried using colour and shape matching however I am not getting the desired results.
I also need to take care of orientation specific components like diodes.
How can I check for floating components like Electrolytic capacitors and Transistors.
I also want to read the text on the components.
Can anyone help me with some examples or resources for the given application?
