Hi,
First off, loving the OpenMV. Installed IDE, plugged in, tried some code → worked first time!
I’m trying to scan QR codes on an A5 sheet. They are about 7mm x 7mm. Hoping to detect version 1 and 2.
So far I’ve tried these settings…
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.VGA)
→ OSError: Image is not mutable!
sensor.set_pixformat(sensor.GRAYSCALE)
sensor.set_framesize(sensor.VGA)
→ MemoryError: Out of fast Frame Buffer Stack Memory! Please reduce the resolution of the image you are running this algorithm on to bypass this issue!
I’ve got to…
sensor.set_pixformat(sensor.GRAYSCALE)
sensor.set_framesize(sensor.CIF)
Unfortunately, this only works for an area less than 10cm x 10cm.
Any way of increasing the area and resolution?
