This is the example code of the QR code. But I have some question about the this code.
What is the code mean in this line
for code in img.find_qrcodes():
And what is the behind of the find_qrcodes() function. How can I find the explanation about the some function.
# QRCode Example # # This example shows the power of the OpenMV Cam to detect QR Codes # using lens correction (see the qrcodes_with_lens_corr.py script for higher performance). import sensor, image, time sensor.reset() sensor.set_pixformat(sensor.RGB565) sensor.set_framesize(sensor.QVGA) sensor.skip_frames(time = 2000) sensor.set_auto_gain(False) # must turn this off to prevent image washout... clock = time.clock() while(True): clock.tick() img = sensor.snapshot() img.lens_corr(1.8) # strength of 1.8 is good for the 2.8mm lens. for code in img.find_qrcodes(): img.draw_rectangle(code.rect(), color = (255, 0, 0)) print(code) print(clock.fps())
