接口介绍:
识别图像中的货币类型,以纸币为主,正反面均可准确识别,接口返回货币的名称、代码、面值、年份信息;可识别各类近代常见货币,如美元、欧元、英镑、法郎、澳大利亚元、俄罗斯卢布、日元、韩元、泰铢、印尼卢比等。
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,以下是货币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>
/// 货币识别
/// </summary>
[Serializable]
public class CurrencyRecognition
{
/// <summary>
/// 请求标识码,随机数,唯一
/// </summary>
public int log_id;
/// <summary>
/// 识别结果
/// </summary>
public CurrencyRecognitionResult result;
}
/// <summary>
/// 货币识别结果
/// </summary>
[Serializable]
public class CurrencyRecognitionResult
{
/// <summary>
/// 判断是否返回详细信息(除货币名称之外的其他字段),含有返回1,不含有返回0
/// </summary>
public int hasdetail;
/// <summary>
/// 货币名称,无法识别返回空
/// </summary>
public string currencyName;
/// <summary>
/// 货币代码,hasdetail = 0时,表示无法识别,该字段不返回
/// </summary>
public string currencyCode;
/// <summary>
/// 货币面值,hasdetail = 0时,表示无法识别,该字段不返回
/// </summary>
public string currencyDenomination;
/// <summary>
/// 货币年份,hasdetail = 0时,表示无法识别,该字段不返回
/// </summary>
public string year;
}
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>
/// 货币识别
/// </summary>
/// <param name="bytes">图片字节数据</param>
/// <returns></returns>
public static CurrencyRecognition Currency(byte[] bytes)
{
var client = new Baidu.Aip.ImageClassify.ImageClassify(apiKey, secretKey);
try
{
var response = client.Currency(bytes);
CurrencyRecognition currencyRecognition = JsonUtility.FromJson<CurrencyRecognition>(response.ToString());
return currencyRecognition;
}
catch (Exception error)
{
Debug.LogError(error);
}
return null;
}
/// <summary>
/// 货币识别
/// </summary>
/// <param name="url">图片url地址</param>
/// <returns></returns>
public static CurrencyRecognition Currency(string url)
{
var client = new Baidu.Aip.ImageClassify.ImageClassify(apiKey, secretKey);
try
{
var response = client.CurrencyUrl(url);
CurrencyRecognition currencyRecognition = JsonUtility.FromJson<CurrencyRecognition>(response.ToString());
return currencyRecognition;
}
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.Currency(File.ReadAllBytes(Application.dataPath "/Picture.jpg"));
}
}
