接口介绍:
识别超过9千种菜品,支持客户创建属于自己的菜品图库,可准确识别图片中的菜品名称、位置、卡路里信息,并获取百科信息,适用于多种客户识别菜品的业务场景中。
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,以下是菜品识别接口返回数据参数详情:
定义数据结构:
using System;
/// <summary>
/// 菜品识别
/// </summary>
[Serializable]
public class DishRecognition
{
/// <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>
/// 菜品识别结果数组
/// </summary>
public DishRecognitionResult[] result;
}
/// <summary>
/// 菜品识别结果
/// </summary>
[Serializable]
public class DishRecognitionResult
{
/// <summary>
/// 菜名
/// </summary>
public string name;
/// <summary>
/// 卡路里,每100g的卡路里含量
/// </summary>
public float calorie;
/// <summary>
/// 识别结果中每一行的置信度值,0-1
/// </summary>
public float probability;
/// <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>
/// 菜品识别
/// </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5</param>
/// <param name="filterThreshold">默认0.95,可以通过该参数调节识别效果,降低非菜识别率.</param>
/// <param name="baikeNum"> 返回百科信息的结果数,默认不返回</param>
/// <returns></returns>
public static DishRecognition Dish(byte[] bytes, int topNum = 5, float filterThreshold = 0.95f, int baikeNum = 0)
{
var client = new Baidu.Aip.ImageClassify.ImageClassify(apiKey, secretKey);
try
{
var options = new Dictionary<string, object>
{
{ "top_num", topNum },
{ "filter_threshold", Mathf.Clamp01(filterThreshold)},
{ "baike_num", baikeNum}
};
var response = client.DishDetect(bytes, options);
DishRecognition dishRecognition = JsonConvert.DeserializeObject<DishRecognition>(response.ToString());
return dishRecognition;
}
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.Dish(File.ReadAllBytes(Application.dataPath + "/Picture.jpg"));
}
}
