Unity接入百度AI实现货币识别
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")); } }
