绝对能用在这里插入图片描述

1.请不要自己使用开源的OCR，识别率巨低，时间成本、优化成本太大！
2.对比网上的价格，百度的智能云更便宜。我算了下是1.6分每次
直接上代码（包含前端和后端，前端展示2种，图一是elementUI，图二是vantui的移动端。后端就是springboot)
我这里贴出来elementui的代码供你参考。
我会将关键参数抹除，你买完把参数直接放上去就能用
elementUI：

<template>
<div class="id-card-container" style="flex: 1;">
						<el-card class="id-card-box">

									class="upload-demo"
									drag

									:data="uploadData"
									:on-success="handleIdCardSuccess"

									:show-file-list="false"
									accept="image/*"
