NuGet Downloads License

DdddOcr的.NET Core 10.0完整重构版本 - 开箱即用的通用验证码识别SDK

✨ 本包已包含完整模型文件（85MB），安装即可使用，无需额外下载！

🚀 快速开始

1. 安装包

dotnet add package DdddOcr.NET

2. 使用

using DdddOcr.Core;

// 创建实例（模型已内置，开箱即用）
using var ocr = new DdddOcr();

// 识别验证码
byte[] imageBytes = File.ReadAllBytes("captcha.png");
string result = ocr.Classification(imageBytes);

Console.WriteLine($"识别结果: {result}");

📦 包含的模型

模型文件 大小 用途
common_old.onnx 13 MB 默认OCR模型（快速）
common.onnx 52 MB Beta版OCR模型（高准确率）
common_det.onnx 19 MB 目标检测模型（YOLOX）

💡 使用示例

基础OCR识别

using var ocr = new DdddOcr();
string code = ocr.Classification(imageBytes);

使用Beta模型（更高准确率）

var config = new OcrConfig { Beta = true };
using var ocr = new DdddOcr(config);
string code = ocr.Classification(imageBytes);

目标检测

using var ocr = new DdddOcr();
var boxes = ocr.Detection(imageBytes);

foreach (var box in boxes)
{
    Console.WriteLine($"位置: ({box.X}, {box.Y}), 置信度: {box.Confidence}");
}

滑块匹配

using var ocr = new DdddOcr();
float offset = ocr.SlideMatch(targetBytes, backgroundBytes);
Console.WriteLine($"滑块偏移: {offset}");

限制字符集

using var ocr = new DdddOcr();
ocr.SetRanges("0123456789");  // 仅数字
string code = ocr.Classification(imageBytes);

⚙️ 配置选项

var config = new OcrConfig
{
    // 模型配置
    ModelsPath = "E:/models",      // 自定义模型路径（可选）
    Old = false,                   // 使用旧版模型
    Beta = true,                   // 使用Beta版模型
    ImportOnnxPath = "",           // 自定义ONNX模型
    CharsetsPath = "",             // 自定义字符集
    
    // 性能配置
    UseGpu = false,                // 启用GPU
    DeviceId = 0                   // GPU设备ID
};

using var ocr = new DdddOcr(config);
