接口介绍:
识别近八千种动物,接口返回动物名称,并可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。适用于拍照识图、幼教科普、图像内容分析等场景
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,以下是动物识别接口返回数据参数详情:
定义数据结构:
using System;
/// <summary>
/// 动物识别
/// </summary>
[Serializable]
public class AnimalRecognition
{
/// <summary>
/// 唯一的log id,用于问题定位
/// </summary>
public float log_id;
/// <summary>
/// 识别结果数组
/// </summary>
public AnimalRecognitionResult[] result;
}
[Serializable]
public class AnimalRecognitionResult
{
/// <summary>
/// 动物名称
/// </summary>
public string name;
/// <summary>
/// 置信度
/// </summary>
public float score;
/// <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:
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>
/// 动物识别
/// </summary>
/// <param name="bytes">图片字节数据</param>
/// <param name="topNum">返回预测得分top结果数,默认为6</param>
/// <param name="baikeNum">返回百科信息的结果数,默认不返回</param>
/// <returns></returns>
public static AnimalRecognition Animal(byte[] bytes, int topNum = 6, int baikeNum = 0)
{
var client = new Baidu.Aip.ImageClassify.ImageClassify(apiKey, secretKey);
try
{
var options = new Dictionary<string, object>
{
{ "top_num", topNum },
{ "baike_num", baikeNum }
};
var response = client.AnimalDetect(bytes, options);
AnimalRecognition animalRecognition = JsonConvert.DeserializeObject<AnimalRecognition>(response.ToString());
return animalRecognition;
}
catch (Exception error)
{
Debug.LogError(error);
}
return null;
}
}
测试图片:
using System.IO;
using UnityEngine;
public class Example : MonoBehaviour
{
private void Start()
{
ImageRecognition.Animal(File.ReadAllBytes(Application.dataPath + "/Picture.jpg"));
}
}
