    • RE: 请问这是摄像头读取不了颜色吗?可以读取的红色、绿色一类的都显示了LAB,但是黄色就显示fps,怎么解决呢???

      @kidswong999 黄色的不是LAB的阈值问题,就是摄像头读取不了,显示不出来。

      import sensor, image, time
      
      sensor.reset()
      sensor.set_pixformat(sensor.RGB565)
      sensor.set_framesize(sensor.QQVGA)
      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()
      
      while(True):
          clock.tick()
          img = sensor.snapshot().lens_corr(1.8)
          for c in img.find_circles(threshold = 3500, x_margin = 10, y_margin = 10, r_margin = 10,
                  r_min = 2, r_max = 100, r_step = 2):
              area = (c.x()-c.r(), c.y()-c.r(), 2*c.r(), 2*c.r())
              #area为识别到的圆的区域,即圆的外接矩形框
              statistics = img.get_statistics(roi=area)#像素颜色统计
              print(statistics)
              #(0,100,0,120,0,120)是红色的阈值,所以当区域内的众数(也就是最多的颜色),范围在这个阈值内,就说明是红色的圆。
              #l_mode(),a_mode(),b_mode()是L通道,A通道,B通道的众数。
              if 0<statistics.l_mode()<100 and 0<statistics.a_mode()<127 and 0<statistics.b_mode()<127:#if the circle is red
                  img.draw_circle(c.x(), c.y(), c.r(), color = (255, 0, 0))#识别到的红色圆形用红色的圆框出来
              elif 0<statistics.l_mode()<100 and -64<statistics.a_mode()<-8 and -32<statistics.b_mode()<32:#if the circle is graeen
                  img.draw_circle(c.x(), c.y(), c.r(), color = (0, 255, 0))#识别到的绿色圆形用绿色的圆框出来
              elif 65<statistics.l_mode()<80 and -10<statistics.a_mode()<10 and 60<statistics.b_mode()<70:#if the circle is red
                   img.draw_circle(c.x(), c.y(), c.r(), color = (0, 0, 255))#识别到的黄色圆形用蓝色的圆框出来
              else:
                  img.draw_rectangle(area, color = (255, 255, 255))
                  #将非红色的圆用白色的矩形框出来
          print("FPS %f" % clock.fps())
