Unity 接入百度Ocr图片转文字

.## 标题 Unity接入百度Ocr图片转文字
代码如下 用来解析返回成功的数据

using System;

/// <summary>
/// 通用文字识别
/// </summary>
[Serializable]
public class GeneralOcr
{
    
    
    /// <summary>
    /// 图像方向 -1未定义 0正弦 1逆时针90度 2逆时针180度 3逆时针270度
    /// </summary>
    public int direction;
    /// <summary>
    /// 唯一的log id，用于问题定位
    /// </summary>
    public int log_id;
    /// <summary>
    /// 识别结果数，表示words_result的元素个数
    /// </summary>
    public int words_result_num;
    /// <summary>
    /// 定位和识别结果数组
    /// </summary>
    public string[] words_result;
    /// <summary>
    /// 行置信度信息
    /// </summary>
    public Probability probability;
}

/// <summary>
/// 行置信度信息
/// </summary>
[Serializable]
public class Probability
{
    
    
    /// <summary>
    /// 行置信度平均值
    /// </summary>
    public int average;
    /// <summary>
    /// 行置信度方差
    /// </summary>
    public int variance;
    /// <summary>
    /// 行置信度最小值
    /// </summary>
    public int min;
}```
## 调用Api传入参数
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Baidu.Aip;
public class OCR 
{
    
    
    //以下信息于百度开发者中心创建应用获取
    private const string appID ="";
    private const string apiKey ="";
    private const string secretKey ="";

    /// <summary>
    /// 通用文字识别
    /// </summary>
    /// <param name="bytes">图片字节数据</param>
    /// <param name="language">识别语言类型 默认CHN_ENG中英文混合</param>
    /// <param name="detectDirection">是否检测图像朝向</param>
    /// <param name="detectLanguage">是否检测语言，当前支持中、英、日、韩</param>
    /// <param name="probability">是否返回识别结果中每一行的置信度</param>
    /// <returns></returns>
    public static GeneralOcr General(byte[] bytes, string language = "CHN_ENG", bool detectDirection = false, bool detectLanguage = false, bool probability = false)
    {
    
    
        var client = new Baidu.Aip.Ocr.Ocr(apiKey, secretKey);
        try
        {
    
    
            var options = new Dictionary<string, object>
            {
    
    
                {
    
     "language_type", language },
                {
    
     "detect_direction", detectDirection },
                {
    
     "detect_language", detectLanguage },
                {
    
     "probability", probability }
            };
            //var response = client.GeneralBasic(bytes, options);
            var response = client.GeneralBasic(bytes, options);
            GeneralOcr generalOcr = JsonUtility.FromJson<GeneralOcr>(response.ToString());
            return generalOcr;
        }
        catch (Exception error)
        {
    
    
            Debug.LogError(error);
        }
        return null;
    }


}
###调用方法将要识别的图片转为byte

 public void LoadImages()
    {
    
    
        string imagePath = EditorUtility.OpenFilePanel("Select Image", "", "png,jpg,jpeg");

        if (!string.IsNullOrEmpty(imagePath))
        {
    
    
            Texture2D texture = new Texture2D(2, 2);
            byte[] imageData = File.ReadAllBytes(imagePath);
            texture.LoadImage(imageData);
            Sprite sprite = Sprite.Create(texture, new Rect(0, 0, texture.width, texture.height), Vector2.one * 0.5f);
            image.sprite = sprite;

            OCR.General(imageData);
        }
    }
