实施前准备工作
一、本地图片上传为OSS
1.开通oss
2.创建Bucket
二、开通目标检测服务
三、查看所需API
这里我们用到阿里云视觉智能开放平台提供的三个功能：
- 车辆部件识别
- 车辆损伤识别
- 车险图片分类
1.车辆部件识别
检测图片中车辆部件的位置以及名称。
2.车辆损伤识别
针对常见小汽车车型，识别车辆外观受损部件及损伤类型，可识别数十种车辆部件、五大类外观损伤。（刮擦、凹陷、开裂、褶皱、穿孔）
3.车险图片分类
对输入的车险图片进行分类。
具体实施
一、本地图片上传至OSS的uploadPic类
车辆部件识别
1.在maven中导入所需依赖
<dependency>
<groupId>com.aliyun.oss</groupId>
<artifactId>aliyun-sdk-oss</artifactId>
<version>3.8.0</version>
</dependency>2.编写UploadPic类
package com.example.demo;
import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import java.io.File;
import java.net.URL;
import java.security.SecureRandom;
import java.util.Date;
import java.lang.*;
import java.util.Scanner;
public class UploadPic {
public static String UploadPic(){
// Endpoint以杭州为例，其它Region请按实际情况填写。
String endpoint = "oss-cn-shanghai.aliyuncs.com";
// 阿里云主账号AccessKey。
String accessKeyId = "*************";
String accessKeySecret = "*************";
//本地文件名
System.out.println("请输入本地图片path:");
Scanner scanner = new Scanner(System.in);
String fileName = scanner.nextLine();
String bucketName = "auto-insurance-pic";
// 获取文件的后缀名
String suffixName = fileName.substring(fileName.lastIndexOf("."));
// 生成上传文件名
String objectName = System.currentTimeMillis() + "" + new SecureRandom().nextInt(0x0400) + suffixName;
// 创建OSSClient实例。
OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
// 如果需要上传时设置存储类型与访问权限，请参考以下示例代码。
// ObjectMetadata metadata = new ObjectMetadata();
// metadata.setHeader(OSSHeaders.OSS_STORAGE_CLASS, StorageClass.Standard.toString());
// metadata.setObjectAcl(CannedAccessControlList.Private);
// putObjectRequest.setMetadata(metadata);
// 上传文件。
ossClient.putObject(bucketName, objectName, new File(fileName));
// 设置URL过期时间为1小时。
Date expiration = new Date(System.currentTimeMillis() + 3600 * 1000);
// 生成以GET方法访问的签名URL，访客可以直接通过浏览器访问相关内容。
URL url = ossClient.generatePresignedUrl(bucketName, objectName, expiration);
// 关闭OSSClient。
ossClient.shutdown();
return url.toString();
}
}3.运行结果

IAcsClient client = new DefaultAcsClient(profile);
RecognizeVehiclePartsRequest request = new RecognizeVehiclePartsRequest();
request.setRegionId("cn-shanghai");
request.setImageURL(UploadPic.UploadPic());
try {
RecognizeVehiclePartsResponse response = client.getAcsResponse(request);
System.out.println(new Gson().toJson(response));
} catch (ServerException e) {
e.printStackTrace();
} catch (ClientException e) {
System.out.println("ErrCode:" + e.getErrCode());
