这是我自己做的一个类似滴滴打车的Android出行项目，主要针对滴滴等出行平台一直饱受质疑的“人车不符”问题，以及当前越发火热的或计划和出海战略，给出行项目增加了下面几个功能： 1. RFID识别验证功能：在司机证件或者车内识别硬件嵌入RFID识别芯片，乘客使用手机读取到芯片信息，并且通过网络发送到出行平台数据库进行验证（我用JNI加了一个C语言的MD5加密算法对识别到的信息进行了加密）。如果不是合规的“人”或“车”，则不能完成订单并向平台或监管单位汇报当前位置。（为了方便读者测试，可以使用手机读取任何一个加密或非加密RFID芯片，比如银行卡、公交卡等，我在代码中的验证前阶段把芯片信息都换成我自己的司机信息，确保读者测试时可以收到服务器的回复） 2. 海外版功能：点击切换当前语言。 3. 司机证件号码识别功能：读取司机证件上的证件号码，也可以用来与出行平台数据库的接单司机信息进行。I complete this whole project on my own . Including Android application programming，web server ( Apache + PHP + MySQL), and UI. 1．Map route planing。You can use mobile phone choose pick up & destination address，application provide address name hint and draw optimized route for user , then call car for you. 2．RFID authentication function：User can use application to scan driver license or other RFID hardware, then use NDK MD5 algorithm encrypt RFID number, and send it to Web Server Database, check with driver information and authenticate ID number , if ID number coherent with driver info , send back driver information to User and continue call car order . record user location and alert if ID not coherent. 3．Driver License Number Recognition : Application can recognize driver license digit number ,and also can send to web server for authentication & feed back result to user.

你好，所有的接口数据都是抓包？是否考虑做一个ios版？

根据特征向量对证件号码进行识别

//根据特征向量对证件号码进行识别
public int recognitionChar(Mat charImage) {
String result = "";
File file = new File(FEATURE_FILE_PATH);
//遍历FEATURE_FILE_PATH 下的特征文件
File[] featureDataFiles = file.listFiles();
double minDistance = Double.MAX_VALUE;
//获取到特征数据
float[] fv = extractFeatureData(charImage);

    for (File f : featureDataFiles) {
        //readFeatureVector 方法计算与目标特征的最小距离
        double dist = calculateDistance(fv, readFeatureVector(f));
        if (minDistance > dist) {
            minDistance = dist;
            result = f.getName();
        }
    }
    Log.i("OCR-INFO", result);
    return Integer.parseInt(result.substring(0, 1));  
}

return 这里为什么返回的是文件名字的substring ，文件名为feature_0.txt ，这里就崩溃了，没有看懂这里的含义，能否解释一下呢，多谢大神！

证件号建议打下马赛克

导入就能用吗？我下载了ndk 以及cmake还是运行不起来
