JAVA演示阿里云圖像識別API,印刷文字識別-營業(yè)執(zhí)照識別

 更新時(shí)間:2019年05月03日 15:14:26   投稿:WDC  
最近有由于工作需要,開始接觸阿里云的云市場的印刷文字識別API-營業(yè)執(zhí)照識別這里我加上了官網(wǎng)的申請說明,只要你有阿里云賬號就可以用,前500次是免費(fèi)的,API說明很簡陋,只能做個(gè)簡單參考

最近有由于需要,我開始接觸阿里云的云市場的印刷文字識別-營業(yè)執(zhí)照識別這里我加上了官網(wǎng)的申請說明,只要你有阿里云賬號就可以用,前500次是免費(fèi)的,API說明很簡陋,只能做個(gè)簡單參考。

一、API介紹

JAVA示例: 

public static void main(String[] args) {
   String host = "https://dm-58.data.aliyun.com";
   String path = "/rest/160601/ocr/ocr_business_license.json";
   String method = "POST";
   String appcode = "你自己的AppCode";
   Map<String, String> headers = new HashMap<String, String>();
   //最后在header中的格式(中間是英文空格)為Authorization:APPCODE 83359fd73fe94948385f570e3c139105
   headers.put("Authorization", "APPCODE " + appcode);
   //根據(jù)API的要求,定義相對應(yīng)的Content-Type
   headers.put("Content-Type", "application/json; charset=UTF-8");
   Map<String, String> querys = new HashMap<String, String>();
   String bodys = "{\"image\":\"對圖片內(nèi)容進(jìn)行Base64編碼\"}";


   try {
   /**
   * 重要提示如下:
   * HttpUtils請從
   * https://github.com/aliyun/api-gateway-demo-sign-java/blob/master/src/main/java/com/aliyun/api/gateway/demo/util/HttpUtils.java
   * 下載
   *
   * 相應(yīng)的依賴請參照
   * https://github.com/aliyun/api-gateway-demo-sign-java/blob/master/pom.xml
   */
   HttpResponse response = HttpUtils.doPost(host, path, method, headers, querys, bodys);
   System.out.println(response.toString());
   //獲取response的body
   //System.out.println(EntityUtils.toString(response.getEntity()));
   } catch (Exception e) {
   e.printStackTrace();
   }
 }

返回碼:

{
  "config_str" : "null\n", #配置字符串信息
  "angle" : float, #輸入圖片的角度(順時(shí)針旋轉(zhuǎn)),[0, 90, 180,270]
  "reg_num" : string, #注冊號,沒有識別出來時(shí)返回"FailInRecognition"
  "name" : string, #公司名稱,沒有識別出來時(shí)返回"FailInRecognition"
  "type" : string, #公司類型,沒有識別出來時(shí)返回"FailInRecognition"
  "person" : string, #公司法人,沒有識別出來時(shí)返回"FailInRecognition"
  "establish_date": string, #公司注冊日期(例:證件上為"2014年04月16日",算法返回"20140416")
  "valid_period": string, #公司營業(yè)期限終止日期(例:證件上為"2014年04月16日至2034年04月15日",算法返回"20340415")
  #當(dāng)前算法將日期格式統(tǒng)一為輸出為"年月日"(如"20391130"),并將"長期"表示為"29991231",若證件上沒有營業(yè)期限,則默認(rèn)其為"長期",返回"29991231"。
  "address" : string, #公司地址,沒有識別出來時(shí)返回"FailInRecognition"
  "capital" : string, #注冊資本,沒有識別出來時(shí)返回"FailInRecognition"
  "business": string, #經(jīng)營范圍,沒有識別出來時(shí)返回"FailInRecognition"
  "emblem" : string, #國徽位置[top,left,height,width],沒有識別出來時(shí)返回"FailInDetection"
  "title" : string, #標(biāo)題位置[top,left,height,width],沒有識別出來時(shí)返回"FailInDetection"
  "stamp" : string, #印章位置[top,left,height,width],沒有識別出來時(shí)返回"FailInDetection"
  "qrcode" : string, #二維碼位置[top,left,height,width],沒有識別出來時(shí)返回"FailInDetection"
  "success" : bool, #識別成功與否 true/false
  "request_id": string
}

購買后,在云市場列表里展示,你可要點(diǎn)擊進(jìn)去查看AppCode等其主要信息(接口調(diào)用里需要AppCode)

簡單的API介紹,但挺有效了的,唯一不好的就是沒有錯(cuò)誤返回碼的描述,需要自己測試。

二、代碼開發(fā)

#aliyun business licence recognition
businessLicenceHost = https://dm-58.data.aliyun.com
businessLicencePath = /rest/160601/ocr/ocr_business_license.json
appCode = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

三、測試結(jié)果

成功的結(jié)果:

失敗結(jié)果,當(dāng)處理非營業(yè)執(zhí)照的圖片時(shí)將會(huì)返回“invalid business licence”結(jié)果,我這么沒有進(jìn)行判斷處理直接按照正確的json解析,所以報(bào)錯(cuò),此處你們可以按照自己需求選擇處理邏輯。從這返回結(jié)果也看的出該接口做的不合理,返回內(nèi)容不統(tǒng)一,導(dǎo)致接口使用者,必須知曉各種情況才能做有效的處理,如果此處能返回json串,給錯(cuò)誤碼那對于調(diào)用者來說就方便多了。

四、后記

此API適合一般的營業(yè)執(zhí)照和新的三證合一的營業(yè)執(zhí)照,但是字段獲取的含義不同,此處需要注意;
由于API并未列出錯(cuò)誤碼,在未知的錯(cuò)誤情況還包含識別次數(shù)不夠的時(shí)候是報(bào)錯(cuò)還是有錯(cuò)誤提示(由于條件限制,此情況無法驗(yàn)證);

工具是死的,人是活的,開發(fā)需要考慮盡可能多的情況,來保證代碼的完善。
至此,工具介紹完畢,歡迎交流。
