文字识别 OCR-识别结果后处理:提取特定字段导入Excel

提取特定字段导入Excel 本示例调用身份证识别API，并从获取到的JSON结果中，提取所需的字段，填入至Excel。前提条件开通身份证识别。参考本地调用，安装OCR Python SDK。并执行pip install xlsxwriter命令安装依赖包。登录访问密钥页面，获取AK、SK。可以新增访问密钥，或使用已有的访问密钥。访问密钥为credentials.csv文件，包含AK/SK信息。代码示例 # -*- coding: utf-8 -*- import base64 import xlsxwriter from huaweicloudsdkcore.auth.credentials import BasicCredentials from huaweicloudsdkocr.v1.region.ocr_region import OcrRegion from huaweicloudsdkcore.exceptions import exceptions from huaweicloudsdkocr.v1 import * from huaweicloudsdkcore.http.http_config import HttpConfig def recognize_id_card_request(): try: request = RecognizeIdCardRequest() request.body = IdCardRequestBody( image=image_base64 ) response = client.recognize_id_card(request) return response except exceptions.ClientRequestException as e: print(e.status_code) print(e.request_id) print(e.error_code) print(e.error_msg) def get_credential(): return BasicCredentials(ak, sk) def get_client(): config = HttpConfig.get_default_config() config.ignore_ssl_verification = True return OcrClient.new_builder(OcrClient) \ .with_credentials(credentials) \ .with_region(OcrRegion.CN_NORTH_4) \ .with_http_config(config) \ .build() def image_to_base64(imagepath): """ 将本地图片转化为base64编码 """ with open(imagepath, "rb") as bin_data: image_data = bin_data.read() base64_data = base64.b64encode(image_data).decode("utf-8") return base64_data def response_to_execl(save_file, data): """ :param save_file: 文件名 :param data: result data """ # 处理调用API返回的result数据 keys_list = list(data["result"].keys()) values_list = list(data["result"].values()) options = {'in_memory': True} with xlsxwriter.Workbook(save_file, options) as workbook: worksheet = workbook.add_worksheet() worksheet.set_column('A1:A20', 23) worksheet.set_column('B1:B20', 100) worksheet.write_column('A1', keys_list) worksheet.write_column('B1', values_list) workbook.close() if __name__ == '__main__': # 填写访问密钥AK、SK ak = "填写AK" sk = "填写SK" # Init Auth Info credentials = get_credential() # Create OcrClient client = get_client() image_base64 = image_to_base64(r"图片的路径，例如D:\local\test.png") # request id card service response = recognize_id_card_request().to_dict() # 数据保存在execl上 response_to_execl(r"excel路径，例如D:\local\test.xlsx", response)
