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"}, // {"probability":{"average":0.871825,"min":0.744326,"variance":0.016256},"words":"酿造"}], // "words_result_num":2,"language":-1,"direction":0}
