AprilTags Example

This example shows the power of the OpenMV Cam to detect April Tags

on the OpenMV Cam M7. The M4 versions cannot detect April Tags.

import sensor, image, time, math

sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QQVGA) # we run out of memory if the resolution is much bigger...
sensor.skip_frames(30)
sensor.set_auto_gain(False) # must turn this off to prevent image washout...
sensor.set_auto_whitebal(False) # must turn this off to prevent image washout...
clock = time.clock()

while(True):
clock.tick()
img = sensor.snapshot()
for tag in img.find_apriltags(): # defaults to TAG36H11 without "families".
img.draw_rectangle(tag.rect(), color = (255, 0, 0))
img.draw_cross(tag.cx(), tag.cy(), color = (0, 255, 0))
degress = 180 * tag.rotation() / math.pi
print(tag.id(),degress)
