    • 通过二值化得到了白色区域,如何将白色区域真正的颜色显示出来?

      1.创建了原图像的副本
      2.对图像副本进行二值化操作
      3.将原图像与二值化后的图像进行按像素相乘
      未达到理想效果

      import sensor, image, time ,pyb
      
      sensor.reset()                      # Reset and initialize the sensor.
      sensor.set_pixformat(sensor.RGB565) # Set pixel format to RGB565 (or GRAYSCALE)
      sensor.set_framesize(sensor.QVGA)   # Set frame size to QVGA (320x240)
      sensor.skip_frames(time = 2000)     # Wait for settings take effect.
      clock = time.clock()                # Create a clock object to track the FPS.
      sensor.set_auto_gain(False) # must be turned off for color tracking
      sensor.set_auto_whitebal(False) # must be turned off for color tracking
      threshold = (0,100,7,66,-22,54)
      while(True):
          a=[0]*3
          img = sensor.snapshot()         # Take a picture and return the image.
          img1 = img.copy(copy_to_fb=img)
          img1 = img.binary([threshold])
          img.mul(img,invert=0,mask=img1)
          print(img.get_pixel(159,88))

    • openmv可以单独读RGB一个通道的值嘛?

      只提取整个图片红色部分,然后对这个通道再进行二值化操作,可以实现吗?
