怎么使用“threshold.value()”拿出阈值.

[15659670865]

利用“histogram.get_threshold()”得到最佳阈值后，想使用“threshold.value()”拿出阈值，失败了..

THRESHOLD = [0, 100] # Grayscale threshold for dark things...
BINARY_VISIBLE = True # Does binary first so you can see what the linear regression
                      # is being run on... might lower FPS though.

import sensor, image, time
from pyb import LED

sensor.reset()
sensor.set_pixformat(sensor.GRAYSCALE)
sensor.set_framesize(sensor.QQQVGA) # 80x60 (4,800 pixels) - O(N^2) max = 2,3040,000.
sensor.skip_frames(time = 2000)     # WARNING: If you use QQVGA it may take seconds
clock = time.clock()                # to process a frame sometimes.

LED(1).on()
LED(2).on()
LED(3).on()

while(True):
    clock.tick()
    img = sensor.snapshot().lens_corr(strength = 0.5, zoom = 1.0)
    img.gaussian(3, unsharp=True)

    histogram = img.get_histogram()#得到直方图
    Thresholds = histogram.get_threshold()#得到最佳阈值
    THR=threshold.value()#获取当前阈值

    #img.binary([THRESHOLD])if BINARY_VISIBLE else sensor.snapshot()

    line = img.get_regression([(255,255) if BINARY_VISIBLE else THRESHOLD], robust = True)

    if (line): img.draw_line(line.line(), color = 127)
