首先,你需要在百度智能云官网注册一个账号并创建一个车牌识别应用,获取API Key和Secret Key。然后安装百度AI的Python SDK:
```bash
pip install baidu-aip
```
接下来,编写一个基于摄像头识别车牌号并打印出车牌信息文本的程序:
```python
from aip import AipOcr
import cv2
# 替换为你的API Key和Secret Key
APP_ID = '你的APP_ID'
API_KEY = '你的API_KEY'
SECRET_KEY = '你的SECRET_KEY'
client = AipOcr(APP_ID, API_KEY, SECRET_KEY)
def get_file_content(file_path):
with open(file_path, 'rb') as fp:
return fp.read()
def recognize_license_plate(image):
options = {
'detect': True,
'language_type': 'CHN_ENG',
}
result = client.licensePlate(get_file_content(image), options)
return result['words_result'][0]['words'] if result['words_result'] else None
def main():
cap = cv2.VideoCapture(0)
while True:
ret, frame = cap.read()
if not ret:
break
license_plates = recognize_license_plate(frame)
if license_plates:
print('车牌号:', ' '.join(license_plates))
cv2.imshow('License Plate Recognition', frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
if __name__ == '__main__':
main()
```
运行这个程序,它将打开摄像头并实时识别车牌号。按“q”键退出程序。
```bash
pip install baidu-aip
```
