小帅拿到了一个手部关键点识别的内测接口。已经有开发者写了PHP的示例。小帅就来写个Java的示例哈。方便咱们Java开发者们哦

• 百科手相的资料

手相其源有西洋、印度和中国三支，中国民间的手相学源远而流长，终成博杂大观。

掌纹也会随着时间发生变化。看手相分男左女右，拿男生举例子，35岁之前看左手，35之后看右手（女生相反）

• 本文其实只是拿关键点简单做一个分析，并不是代表接口所支持功能哦

接口说明可以参考 https://ai.baidu.com/docs#/Body-API/2757b503

基于现有sdk版本进行 实现此接口调用 调用前请自行确认是否已经找梅姐申请了接口权限哦

使用Maven搭建一个工程

pom引入百度Java sdk

// gradle
compile group: 'com.baidu.aip', name: 'java-sdk', version: '4.11.3'
//xml格式会丢失标签。社区技术要看一下哦。语言最好也支持xml 开发者们自行访问以下地址 复制maven的xml配置内容即可
https://mvnrepository.com/artifact/com.baidu.aip/java-sdk/4.11.3

创建一个类来实现手部关键点接口调用
其实就是继承sdk的AipBodyAnalysis

import com.baidu.aip.bodyanalysis.AipBodyAnalysis;
import com.baidu.aip.error.AipError;
import com.baidu.aip.http.AipRequest;
import com.baidu.aip.util.Base64Util;
import com.baidu.aip.util.Util;
import org.json.JSONObject;

import java.io.IOException;
import java.util.HashMap;

public class AipBodyAnalysisInvitation extends AipBodyAnalysis{
    //手部关键点识别
    static final String HAND_ANALYSIS = "https://aip.baidubce.com/rest/2.0/image-classify/v1/hand_analysis";

    public AipBodyAnalysisInvitation(String appId, String apiKey, String secretKey) {
        super(appId, apiKey, secretKey);
    }

    /**
     * 手部关键点识别方法
     * @param image 手部图片本地路径
     * @param options 其他参数
     * @return
     */
    public JSONObject handAnalysis(String image, HashMap options) {
        AipRequest request = new AipRequest();
        preOperation(request);
        try {
            byte[] data = Util.readFileByBytes(image);
            String base64Content = Base64Util.encode(data);
            request.addBody("image", base64Content);
            if (options != null) {
                request.addBody(options);
            }
            request.setUri(HAND_ANALYSIS);
            postOperation(request);
            return requestServer(request);
        } catch (IOException e) {
            e.printStackTrace();
            return AipError.IMAGE_READ_ERROR.toJsonResult();
        }
    }
  
}

准备一个手掌图片

小帅离而立之年还有很久。基于百科所说明，那就使用左手图片

小插曲。如果颜色有问题。会导致识别为空。这个要找梅姐反馈一下。

我这用社区兑换的单反相机 对着自己的左手拍了好几张才有一张符合要求识别出来。

开始用接口去获取手部关键点
Java代码

import org.json.JSONObject;

import java.util.HashMap;

public class TestBody {
    public static void main(String[] args) throws Exception{
        //自己应用的appid apikey secretkey
        AipBodyAnalysisInvitation body = new AipBodyAnalysisInvitation("","","");
        //本地图片路径
        String path = "/Users/xiaoshuai/Downloads/DSC00286.JPG";
        HashMap options = new HashMap();
        JSONObject object = body.handAnalysis(path,options);
        //输出接口识别内容
        System.out.println("object = " + object);
    }
}

 返回的json数据

21个骨节点坐标信息 过多 就不格式化显示了

21个骨节点手相学的图示和标注图示

接下来咱们就拿着坐标去看个手相

返回的数据如下。从心理自我认为看出。还是很符合小帅的性格的哈。

手相详细分析仅作于本帖。娱乐而已。不提供具体接口地址。请知悉

整体来说。接口还是可以的。

梅姐是否考虑增加手掌各个纹理的位置返回呢。这样生命线、事业线、感情线、智慧线就通通都有了。可以让很多产品落地了。哈哈
