OpenMV and robotic arms

Postby chenyukai » Wed Jul 17, 2019 4:06 am

Can OpenMV recognize cylinders and cuboids? Is the shooting direction front or above? If it is mounted on the robot arm, does shaking have a big impact on OpenMV image recognition?

What i know, you have algorythms to detect circle and rectangle which are the top and the side of a cylinder lol

For image recognition, the pre-requesite is to have a sharpen image, and you can have this with
- a fixed focus
- global shutter
- quick exposition
- and sharpen algorythm
Avoiding to to do light painting images.

It is not a function, it is the lens wich is fixed focus or auto focus !
If you use default lens of openmv, it is all fixed focus
