Unity接入百度AI實現貨幣識別
接口介紹:
識別圖像中的貨幣類型,以紙幣為主,正反面均可準確識別,接口返回貨幣的名稱、代碼、面值、年份信息;可識別各類近代常見貨幣,如美元、歐元、英鎊、法郎、澳大利亞元、俄羅斯盧佈、日元、韓元、泰銖、印尼盧比等。
創建應用:
在產品服務中搜索圖像識別,創建應用,獲取AppID、APIKey、SecretKey信息:
查閱官方文檔,以下是貨幣識別接口返回數據參數詳情:
定義數據結構:
using System; /// <summary> /// 貨幣識別 /// </summary> [Serializable] public class CurrencyRecognition { /// <summary> /// 請求標識碼,隨機數,唯一 /// </summary> public int log_id; /// <summary> /// 識別結果 /// </summary> public CurrencyRecognitionResult result; } /// <summary> /// 貨幣識別結果 /// </summary> [Serializable] public class CurrencyRecognitionResult { /// <summary> /// 判斷是否返回詳細信息(除貨幣名稱之外的其他字段),含有返回1,不含有返回0 /// </summary> public int hasdetail; /// <summary> /// 貨幣名稱,無法識別返回空 /// </summary> public string currencyName; /// <summary> /// 貨幣代碼,hasdetail = 0時,表示無法識別,該字段不返回 /// </summary> public string currencyCode; /// <summary> /// 貨幣面值,hasdetail = 0時,表示無法識別,該字段不返回 /// </summary> public string currencyDenomination; /// <summary> /// 貨幣年份,hasdetail = 0時,表示無法識別,該字段不返回 /// </summary> public string year; }
下載C# SDK:
下載完成後將AipSdk.dll動態庫導入到Unity中:
以下是調用接口時傳入的參數詳情:
封裝調用函數:
using System; using System.Collections.Generic; using UnityEngine; /// <summary> /// 圖像識別 /// </summary> public class ImageRecognition { //以下信息於百度開發者中心控制臺創建應用獲取 private const string appID = ""; private const string apiKey = ""; private const string secretKey = ""; /// <summary> /// 貨幣識別 /// </summary> /// <param name="bytes">圖片字節數據</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> /// 貨幣識別 /// </summary> /// <param name="url">圖片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; } }
測試圖片:
using System.IO; using UnityEngine; public class Example : MonoBehaviour { private void Start() { ImageRecognition.Currency(File.ReadAllBytes(Application.dataPath + "/Picture.jpg")); } }
