    • # 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。
