健康码识别（红/黄/蓝/绿）

使用场景：后台将通过收集的所有健康码图片进行批量识别后，将红马、黄码人员通知到指定人，以便后续跟踪
环境：ubuntu20 python3.9  opencv4.5  jdk8

通过Java调用脚本的传参形式实现java和python交互
    
```
class:CmdProcessUtils
    /**
     * 执行python脚本
     * @param pythonFile
     * @param url
     * @return
     */
    public synchronized static String invokePython(String pythonFile,String url){
        if(org.apache.commons.lang3.StringUtils.isEmpty(url)){
            return null;
        }
        try {
            String pythonPath=pythonFile;
            String[] args = new String[] { "python3", pythonPath, url};
            Process proc = Runtime.getRuntime().exec(args);// 执行py文件
            BufferedReader in = new BufferedReader(new InputStreamReader(proc.getInputStream()));
            String line = null;
            StringBuffer buffer=new StringBuffer();
            while ((line = in.readLine()) != null) {
                buffer.append(line);
            }
            in.close();
            proc.waitFor();
            return buffer.toString();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
```

 将脚本上传至服务器，直接调用，将脚本输出的json结果进行接受解析即可
 `String _regResult = CmdProcessUtils.invokePython("xxx/HeathCodeReg.py", localPath);`
