运行你的openMV代码报错：语法错误 无效语法

抱歉，我之前提供的代码有误。OpenMV的代码是使用MicroPython编写的，而不是Arduino的C++代码。以下是OpenMV代码的正确版本：

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())

请确保你在OpenMV设备上正确执行该代码。如果你仍然遇到问题，请提供更详细的错误信息，以便我可以帮助你解决问题。
