openMV用UART库将以下代码通过串口发送给arduino: import sensor import image import time sensor.reset() sensor.set_pixformat(sensor.RGB565) sensor.set_framesize(sensor.QQVGA) sensor.skip_frames(time=2000) clock = time.clock() while True: clock.tick() img = sensor.snapshot().lens_corr(1.8) #检测圆形 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): img.draw_circle(c.x(), c.y(), c.r(), color=(255, 0, 0)) print(c) img = sensor.snapshot() #检测矩形 for r in img.find_rects(threshold=10000): img.draw_rectangle(r.rect(), color=(255, 0, 0)) for p in r.corners(): img.draw_circle(p[0], p[1], 5, color=(0, 255, 0)) print(r) #检测三角形 sum_theta = 0 count = 0 for l in img.find_line_segments(merge_distance=10, max_theta_diff=10): img.draw_line(l.line(), color=(255, 0, 0)) sum_theta += l.theta() count += 1 avg_theta = sum_theta / count if count > 0 else 0 if 1 < avg_theta < 110: print('三角形') print("FPS %f" % clock.fps())

你可以使用以下代码将上述代码通过串口发送给Arduino：

import serial

# 打开串口
ser = serial.Serial('/dev/ttyUSB0', 9600)  # 根据实际情况修改串口号和波特率

# 发送代码
code = '''
import sensor
import image
import time

sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QQVGA)
sensor.skip_frames(time=2000)
clock = time.clock()

while True:
    clock.tick()
    img = sensor.snapshot().lens_corr(1.8)

    # 检测圆形
    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):
        img.draw_circle(c.x(), c.y(), c.r(), color=(255, 0, 0))
        print(c)

    img = sensor.snapshot()

    # 检测矩形
    for r in img.find_rects(threshold=10000):
        img.draw_rectangle(r.rect(), color=(255, 0, 0))
        for p in r.corners():
            img.draw_circle(p[0], p[1], 5, color=(0, 255, 0))
        print(r)

    # 检测三角形
    sum_theta = 0
    count = 0
    for l in img.find_line_segments(merge_distance=10, max_theta_diff=10):
        img.draw_line(l.line(), color=(255, 0, 0))
        sum_theta += l.theta()
        count += 1

    avg_theta = sum_theta / count if count > 0 else 0
    if 1 < avg_theta < 110:
        print('三角形')

    print("FPS %f" % clock.fps())
'''

# 发送代码到Arduino
ser.write(code.encode('utf-8'))

# 关闭串口
ser.close()

请根据你的实际情况修改串口号和波特率。代码中使用了pyserial库来实现串口通信，需要提前安装。代码中将代码以字符串形式发送到Arduino，Arduino可以通过串口接收并执行。
