import sensor, image, time, pyb

sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.GRAYSCALE) # or sensor.GRAYSCALE
sensor.set_framesize(sensor.B128X128) # or sensor.QQVGA (or others)
sensor.set_windowing((92,112))
sensor.skip_frames(10) # Let new settings take affect.
sensor.skip_frames(time = 1000)
while(True):
    img = sensor.snapshot()
    roi1=(10,0,80,60)
    roi2=(40,20,78,20)
    d1= img.find_lbp(roi1)
    d1= img.find_lbp(roi2)

用的M7模块，运行后直接断电

find_lbp程序是错的，导致重启。

@kidswong999 能不能解释一下为什么错了，如何解决错误

sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.GRAYSCALE) # or sensor.GRAYSCALE
sensor.set_framesize(sensor.B128X128) # or sensor.QQVGA (or others)
sensor.set_windowing((92,112))
sensor.skip_frames(10) # Let new settings take affect.
sensor.skip_frames(time = 1000)
while(True):
img = sensor.snapshot()
roi1=(10,0,80,60)
d1= img.find_lbp(roi1)

删去部分函数，只重复给d1赋值相同的lbp时，不会断电

看我链接里的例子，是正确的。
