前言
基于华为云ai服务和java使用sdk实现图像识别，主要以媒资图像标签和名人识别为例。
一、环境配置
- maven（没有直接下载华为的sdk包，而是使用maven安装依赖）
- jdk19（官方的sdk包要求jdk版本必须高于jdk8版本，大家根据自己只要满足版本要求即可）
- 开发工具：idea 2023.3（其他版本也可）
- 能创建maven项目即可
- 开通图像识别服务（目前是免费体验）：这里我开通的是图像标签/媒资图像标签和名人识别服务。
- 设置访问密钥
- 服务区域：我开通的服务区域是华北-北京四
关键步骤
开通图像识别服务
华为云首页就有云产品体验区（找不到就在搜索栏检索），勾选ai：
点击“立即体验”后，找到服务列表，开通你想要的服务（点击开通）：
设置访问密钥
在控制台找到“我的凭证”：
找到“访问密钥”，如果没有就新增，新增后一定要下载密钥的csv文件，他会有提示让你下载，防止你忘记：
下载完csv文件后用记事本打开即可看到ak和sk：
maven引入依赖配置
版本可以自己切换

二、图像识别实例
媒资图像标签
使用图片是网上的，仅作学习使用：
代码如下：
/**
* @version: 1.0.0
* @author: dragon_王
* @classname: runimagemediataggingsolution
* @description: 媒资图像标签
* @date: 2024/1/8 11:51
*/
/**
* 此demo仅供测试使用，强烈建议使用sdk
* 使用前需配置依赖jar包。jar包可通过下载sdk获取
*/
import com.huaweicloud.sdk.core.auth.icredential;
import com.huaweicloud.sdk.core.auth.basiccredentials;
import com.huaweicloud.sdk.core.exception.connectionexception;
import com.huaweicloud.sdk.core.exception.requesttimeoutexception;
import com.huaweicloud.sdk.core.exception.serviceresponseexception;
import com.huaweicloud.sdk.image.v2.region.imageregion;
import com.huaweicloud.sdk.image.v2.*;
import com.huaweicloud.sdk.image.v2.model.*;
public class runimagemediataggingsolution {
public static void main(string[] args) {
//此处需要输入您的ak/sk信息
string ak = "你的ak";
string sk = "你的sk";
icredential auth = new basiccredentials()
.withak(ak)
.withsk(sk);
imageclient client = imageclient.newbuilder()
.withcredential(auth)
.withregion(imageregion.valueof("cn-north-4")) //此处替换为您开通服务的区域
.build();
runimagemediataggingrequest request = new runimagemediataggingrequest();
imagemediataggingreq body = new imagemediataggingreq();
body.withthreshold(10f);
body.withlanguage("zh");
body.withurl("https://tse2-mm.cn.bing.net/th/id/oip-c.siuenb1-arhtdnqfdicvqahae7?rs=1&pid=imgdetmain"); //此处替换为公网可以访问的图片地址
request.withbody(body);
try {
runimagemediataggingresponse response = client.runimagemediatagging(request);
system.out.println(response.tostring());
} catch (connectionexception e) {
e.printstacktrace();
} catch (requesttimeoutexception e) {
e.printstacktrace();
} catch (serviceresponseexception e) {
e.printstacktrace();
system.out.println(e.gethttpstatuscode());
system.out.println(e.geterrorcode());
system.out.println(e.geterrormsg());
}
}
}
运行结果：
