帮我写个用openmv实现对圆形物体识别的代码，物体是橘色

好的，以下是针对橘色圆形物体识别的OpenMV代码：

import sensor, image, time

# 初始化相机并设置参数
sensor.reset()
sensor.set_framesize(sensor.QVGA)
sensor.set_pixformat(sensor.RGB565)
sensor.set_auto_gain(False)
sensor.set_auto_whitebal(False)
sensor.skip_frames(time = 2000)

# 设置橘色的颜色范围
min_hue = 5
max_hue = 40
min_saturation = 50
max_saturation = 255
min_value = 50
max_value = 255
color_threshold = [(min_hue, min_saturation, min_value), (max_hue, max_saturation, max_value)]

while(True):
    # 获取相机图像
    img = sensor.snapshot()

    # 查找所有橘色圆形物体
    for c in img.find_circles(threshold = 4000, x_margin = 5, y_margin = 5, r_margin = 5,
            r_min = 10, r_max = 100, pixels_threshold = 100, area_threshold = 100):
        # 标记圆形物体
        img.draw_circle(c.x(), c.y(), c.r(), color = (255, 0, 0))

    # 显示图像
    img.show()

希望对你有帮助！
