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))
