这是一段Python代码的循环,不断执行以下步骤:
1. 使用摄像头拍摄一张照片;
2. 在照片中寻找AprilTag,并提取它们的位置、方向等信息;
3. 循环执行这些步骤,直到程序手动结束(由于while循环的条件为True,所以程序会一直运行下去)。

好的,以下是你要发送给Arduino的代码:
```cpp
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#define SCREEN_WIDTH 128
#define SCREEN_HEIGHT 64
#define OLED_RESET -1
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);
void setup() {
Serial.begin(9600);
display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
display.clearDisplay();
}
void loop() {
// 在这里插入你要发送给Arduino的代码
}
```
请将你的代码插入到 `loop()` 函数中,然后上传到你的Arduino板上。注意,你可能需要安装 `Adafruit_GFX` 和 `Adafruit_SSD1306` 库以支持OLED显示屏。
如果你有任何其他问题,请随时提问。
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:
```python
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。
