百度云文字识别 (AIPOcr)

接下来写点关于百度云文字识别的笔记吧.

在这里我根据返回参数写了几个对应的实体类来接收,

写的一个java类继承文档提供的关于文字识别操作类

public class AIPOcrJava extends AipOcr {//设置APPID/AK/SK
    public static final String APP_ID = "*********";
    public static final String API_KEY = "*******************";
    public static final String SECRET_KEY = "************************";

    public AIPOcrJava(){super(APP_ID, API_KEY, SECRET_KEY);
     this.setConnectionTimeoutInMillis(60000);
     this.setSocketTimeoutInMillis(20000);
        System.setProperty("aip.log4j.conf", "classpath/log4j.properties");
    }public AIPOcrJava(String aipId, String aipKey, String secretKey) {super(aipId,aipKey,secretKey);
        this.setConnectionTimeoutInMillis(60000);
        this.setSocketTimeoutInMillis(60000);
        System.setProperty("aip.log4j.conf", "classpath/log4j.properties")

1,通用文字识别

public class AipOcrTest {//通用文字识别
  public static  String basicGeneral (String file){HashMap<String,String> options = new HashMap<>(4);

           options.put("language_type", "CHN_ENG");
          options.put("detect_direction", "true"); // 检测图片朝上
          options.put("detect_language", "true");  // 检测语言,默认是不检查
          options.put("probability", "true");   //是否返回识别结果中每一行的置信度
      AIPOcrJava aipOcrJava = new AIPOcrJava();
     org.json.JSONObject jsonObject = aipOcrJava.basicGeneral(file, options);
      return jsonObject.toString();
  }

// String result = basicGeneral("D:\\BaiDuYun\\webImageTest.jpg");
 //{"log_id":4384474417080234428,"wordsResult":[
 // {"probability":{"average":0.968971,"min":0.955538,"variance":1.8E-4},"words":"甜蜜"},

 // "words_result_num":2,"language":-1,"direction":0}

2,通用文字识别高精度版

public static  JSONObject basicAccurateGeneral (String file) {HashMap<String,String> options = new HashMap<>(4);

    options.put("language_type", "CHN_ENG");
    options.put("detect_direction", "true"); // 检测图片朝上
    options.put("detect_language", "true");  // 检测语言,默认是不检查
    options.put("probability", "true");   //是否返回识别结果中每一行的置信度
    AIPOcrJava aipOcrJava = new AIPOcrJava();
   // JSONObject jsonObject = aipOcrJava.basicAccurateGeneral(file, options);  或者是传url
    byte[] bytes = new byte[0];
    try {bytes = FileCopyUtils.copyToByteArray(new FileInputStream(file));
    } catch (IOException e) {e.printStackTrace();
    }return   aipOcrJava.basicAccurateGeneral(bytes, options);

}

   //高精度版
 // JSONObject result = basicAccurateGeneral("D:\\BaiDuYun\\imageTest2.jpeg");
//    String s = /result.toString();
    //  {"log_id":4759662113465573053,"wordsResult":[

    // {"probability":{"average":0.989808,"min":0.951065,"variance":3.72E-4},"words":"但是我一定很爱那个人"},
    // {"probability":{"average":0.985335,"min":0.878724,"variance":0.001031},"words":"爱情对我来说是爱到他人看不穿"}],
    // "words_result_num":6,"language":-1,"direction":0}
