颜色识别

[3b1u]

我只想让我的openmv识别红色，为什么它还会圈出别的无关区域

import sensor, image, time
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()
rgb_circle=[(66, 27, 70, 13, 127, -128),(74, 35, -80, -2, 35, -3),(73, 0, -21, 127, -59, -3)]
mid_roi=[20,20,280,200]
while(True):
    img=sensor.snapshot()
    for blob in img.find_blobs(rgb_circle,roi=mid_roi,x_stride=110,y_stride=110,merge=False):
        print(blob.code())
        if(blob.code()==1):#001
            print("r")
            img.draw_rectangle(blob.rect(),color=(255,255,255))
            img.draw_cross(blob.cx(), blob.cy())
        if(blob.code()==2):#010
            print("g")
            img.draw_rectangle(blob.rect(),color=(0,0,0))
            img.draw_cross(blob.cx(), blob.cy())
        if(blob.code()==4):#100
            print("b")
            img.draw_rectangle(blob.rect(),color=(255,0,0))
            img.draw_cross(blob.cx(), blob.cy())

颜色识别我始终不知道为什么它会圈出别的区域
