接口介绍:
可识别超过10万类常见物体和场景,接口返回大类及细分类的名称,并支持获取识别结果对应的百科信息;还可使用EasyDL定制训练平台,定制识别分类标签。广泛适用于图像或视频内容分析、拍照识图等业务场景。
创建应用:
在产品服务中搜索图像识别,创建应用,获取AppID、APIKey、SecretKey信息:
查阅官方文档,以下是通用物体和场景识别接口返回数据参数详情:
定义数据结构:
代码语言:javascript复制using System;
/// <summary>
/// 通用物体和场景识别
/// </summary>
[Serializable]
public class AdvancedGeneralRecognition
{
/// <summary>
/// 唯一的log id,用于问题定位
/// </summary>
public float log_id;
/// <summary>
/// 返回结果数目,及result数组中的元素个数
/// </summary>
public int result_num;
/// <summary>
/// 返回结果数组
/// </summary>
public AdvancedGeneralRecognitionResult[] result;
}
/// <summary>
/// 通用物体和场景识别结果
/// </summary>
[Serializable]
public class AdvancedGeneralRecognitionResult
{
/// <summary>
/// 图片中的物体或场景名称
/// </summary>
public string keyword;
/// <summary>
/// 置信度,0-1
/// </summary>
public float score;
/// <summary>
/// 识别结果的上层标签,有部分钱币、动漫、烟酒等tag无上层标签
/// </summary>
public string root;
/// <summary>
/// 百科词条
/// </summary>
public BaikeInfo baike_info;
}
[Serializable]
public class BaikeInfo
{
/// <summary>
/// 对应识别结果百度百科页面链接
/// </summary>
public string baike_url;
/// <summary>
/// 对应识别结果百科图片链接
/// </summary>
public string image_url;
/// <summary>
/// 对应识别结果百科内容描述
/// </summary>
public string description;
}
下载C# SDK:
下载完成后将AipSdk.dll动态库导入到Unity中:
以下是调用接口时传入的参数详情:
封装调用函数:
代码语言:javascript复制using System;
using System.Collections.Generic;
using UnityEngine;
/// <summary>
/// 图像识别
/// </summary>
public class ImageRecognition
{
//以下信息于百度开发者中心控制台创建应用获取
private const string appID = "";
private const string apiKey = "";
private const string secretKey = "";
/// <summary>
/// 通用物体和场景识别
/// </summary>
/// <param name="bytes">图片字节数据</param>
/// <param name="baikeNum">返回百科信息的结果数,默认不返回</param>
/// <returns></returns>
public static AdvancedGeneralRecognition AdvancedGeneral(byte[] bytes, int baikeNum = 0)
{
var client = new Baidu.Aip.ImageClassify.ImageClassify(apiKey, secretKey);
try
{
var options = new Dictionary<string, object>
{
{ "baike_num", baikeNum },
};
var response = client.AdvancedGeneral(bytes, options);
AdvancedGeneralRecognition recognition = JsonConvert.DeserializeObject<AdvancedGeneralRecognition>(response.ToString());
return recognition;
}
catch (Exception error)
{
Debug.LogError(error);
}
return null;
}
}
测试图片:
代码语言:javascript复制using System.IO;
using UnityEngine;
public class Example : MonoBehaviour
{
private void Start()
{
ImageRecognition.AdvancedGeneral(File.ReadAllBytes(Application.dataPath "/Picture.jpg"), 1);
}
}
