I am now seeing this issue with the OpenMV AE3. See the example below. When I try setting the scale any higher “.02”, it gives the out of memory error:
Traceback (most recent call last):
File “”, line 18, in
MemoryError: Out of fast frame buffer stack memory
OpenMV v4.8.1; MicroPython v1.26.0-77; OpenMV-AE3 with AE302F80F55D5AE
Type “help()” for more information..
import csi
import time
csi0 = csi.CSI()
csi0.reset()
csi0.pixformat(csi.GRAYSCALE)
csi0.framesize(csi.QVGA)
csi0.snapshot(time=2000)
clock = time.clock()
while True:
clock.tick()
img = csi0.snapshot()
img.crop(x_scale=.01, y_scale=.01)
tag_list = img.find_apriltags()
print(clock.fps())
