# 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,lcd

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()
lcd.init() # Initialize the lcd screen.

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)
        img.draw_string(code.payload())
    lcd.display(img)
    print(clock.fps())

img.draw_string(code.payload())函数调用的不对啊。要给一个字的坐标。
