可以把这段代码精简吗import sensor, image, time, lcd from pyb import UART sensor.reset() sensor.set_pixformat(sensor.RGB565) sensor.set_framesize(sensor.QQVGA) sensor.skip_frames(time = 2000) lcd.init() sensor.set_auto_gain(False) sensor.set_auto_whitebal(False) clock = time.clock() uart = UART(3, 19200, timeout_char=2000) while(True): clock.tick() img = sensor.snapshot().lens_corr(1.8) lcd.display(img) 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): area = (c.x()-c.r(), c.y()-c.r(), 2c.r(), 2c.r()) statistics = img.get_statistics(roi=area) print(statistics) if 0<statistics.l_mode()<100 and 0<statistics.a_mode()<127 and 0<statistics.b_mode()<127: img.draw_circle(c.x(), c.y(), c.r(), color = (255, 0, 0)) uart.write("find red cirl!\n") time.sleep_ms(2000) else: img.draw_rectangle(area, color = (255, 255, 255)) uart.write("nothing!\n") time.sleep_ms(2000) print("FPS %f" % clock.fps())

可以，精简后的代码如下：

import sensor, image, time, lcd
from pyb import UART

sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QQVGA)
sensor.skip_frames(time=2000)
lcd.init()
sensor.set_auto_gain(False)
sensor.set_auto_whitebal(False)
clock = time.clock()
uart = UART(3, 19200, timeout_char=2000)

while True:
    clock.tick()
    img = sensor.snapshot().lens_corr(1.8)
    lcd.display(img)
    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):
        area = (c.x()-c.r(), c.y()-c.r(), 2*c.r(), 2*c.r())
        statistics = img.get_statistics(roi=area)
        if 0 < statistics.l_mode() < 100 and 0 < statistics.a_mode() < 127 and 0 < statistics.b_mode() < 127:
            img.draw_circle(c.x(), c.y(), c.r(), color=(255, 0, 0))
            uart.write("find red circle!\n")
            time.sleep_ms(2000)
        else:
            img.draw_rectangle(area, color=(255, 255, 255))
            uart.write("nothing!\n")
            time.sleep_ms(2000)
    print("FPS %f" % clock.fps())

这里主要是将代码进行了格式化，去除了一些冗余的空格和一些无用的注释。
