      Single Color RGB565 Blob Tracking Example

      This example shows off single color RGB565 tracking using the OpenMV Cam.

      import sensor, image, time,json
      from pyb import UART

      threshold_index = 0 # 0 for red, 1 for green, 2 for blue

      Color Tracking Thresholds (L Min, L Max, A Min, A Max, B Min, B Max)

      The below thresholds track in general red/green/blue things. You may wish to tune them...

      thresholds = [(0, 98, 92, 17, -128, 127)] # generic_red_thresholds
      #(30, 100, -64, -8, -32, 32), # generic_green_thresholds
      # (0, 30, 0, 64, -128, 0)] # generic_blue_thresholds

      sensor.reset()
      sensor.set_pixformat(sensor.RGB565)
      sensor.set_framesize(sensor.QVGA)
      sensor.skip_frames(time = 2000)
      sensor.set_auto_gain(False) # must be turned off for color tracking
      sensor.set_auto_whitebal(False) # must be turned off for color tracking
      clock = time.clock()

      Only blobs that with more pixels than "pixel_threshold" and more area than "area_threshold" are

      returned by "find_blobs" below. Change "pixels_threshold" and "area_threshold" if you change the

      camera resolution. "merge=True" merges all overlapping blobs in the image.

      uart = UART(3, 19200)
      uart.init(19200, bits=8, parity=None, stop=1)

      while(True):
      clock.tick()
      img = sensor.snapshot()
      for blob in img.find_blobs([thresholds[0]], pixels_threshold=200, area_threshold=200, merge=True):
      img.draw_rectangle(blob.rect())
      img.draw_cross(blob.cx(), blob.cy())
      print(blob.cx(),blob.cy())
      uart.write(blob.cx(),blob.cy())
      time.sleep(1000)
      print(clock.fps())

      这是代码
