@kidswong999 我测了一下霍夫圆检测要180ms左右

import sensor, image, time, pyb

sensor.reset()
sensor.set_pixformat(sensor.GRAYSCALE) # grayscale is faster
sensor.set_framesize(sensor.QQVGA)
sensor.skip_frames(time = 2000)
#sensor.skip_frames(time = 2000)
clock = time.clock()

while(True):
#time_start1 = pyb.millis()
clock.tick()

img = sensor.snapshot()#.lens_corr(1.8)
time_start = pyb.millis()
for c in img.find_circles(threshold = 3500, x_margin = 10, y_margin = 10,
r_margin = 10,r_min = 2, r_max = 100, r_step = 2):
    duration = pyb.elapsed_millis(time_start)
    print(duration)
    img.draw_circle(c.x(), c.y(), c.r(), color = (255, 0, 0))
    


print(clock.fps())
