Unity货币识别

CoderZ1010 人气:0

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:

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: 

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:

using System.IO;
using UnityEngine;
 
public class Example : MonoBehaviour
{
    private void Start()
    {
        ImageRecognition.Currency(File.ReadAllBytes(Application.dataPath + "/Picture.jpg"));
    }
}
