Recognize license plate
The code to recognize license plate is very simple, only 1 line of code is required, as shown below.
# pip install poocr import poocr # 可以填写本地图片的地址:img_path,也可以填写在线图片的地址:img_url # 如果2个都填,则只用在线图片img_url # configPath是配置文件的信息,可以不填 Number = poocr.ocr.LicensePlateOCR( img_path=r'C:\Users\程序员晚枫\temp\math_img.jpg', img_url=r'https://cache.yisu.com/upload/information/20230317/112/9432.jpg', configPath=r'D:\workplace\code\github\poocr\tests\poocr-config.toml') print(Number)
This interface supports the automatic positioning and recognition of motor vehicle license plates in mainland China, and returns regional number, license plate number and license plate color information.

{ ... "LicensePlateInfos": [ { "Number": "京Q58888", ... "Color": "蓝" } ], "RequestId": "2be9b49d-d1ce-4344-83e8-771ea929bb97" } ...
Extended functions
In addition, there are 6 interfaces related to vehicle recognition, which are:
# pip install poocr import poocr # 识别驾驶证 ressult = poocr.ocr.DriverLicenseOCR() # 识别行驶证 ressult = poocr.ocr.VehicleLicenseOCR() # 识别机动车登记证 ressult = poocr.ocr.VehicleRegCertOCR() # 识别网约车驾驶证 ressult = poocr.ocr.RideHailingDriverLicenseOCR() # 识别网约车运输证 ressult = poocr.ocr.RideHailingTransportLicenseOCR() # 识别车辆VIN码 ressult = poocr.ocr.VinOCR()
Notes
The implementation of this function, It relies on Tencent Cloud's text recognition, so if you are a novice user, please configure a poocr-config.toml
file in the same directory.
The file contents are as follows.

The methods to debug the shebang problem include: 1. Check the shebang line to make sure it is the first line of the script and there are no prefixed spaces; 2. Verify whether the interpreter path is correct; 3. Call the interpreter directly to run the script to isolate the shebang problem; 4. Use strace or trusts to track the system calls; 5. Check the impact of environment variables on shebang.

Create multi-dimensional arrays with NumPy can be achieved through the following steps: 1) Use the numpy.array() function to create an array, such as np.array([[1,2,3],[4,5,6]]) to create a 2D array; 2) Use np.zeros(), np.ones(), np.random.random() and other functions to create an array filled with specific values; 3) Understand the shape and size properties of the array to ensure that the length of the sub-array is consistent and avoid errors; 4) Use the np.reshape() function to change the shape of the array; 5) Pay attention to memory usage to ensure that the code is clear and efficient.
