解密OCR加密包为NCNN模型 - OcrDecryptModel ​

函数简介 ​

将欧拉 OCR 加密包还原为四文件 NCNN 模型及可选字典。

接口名称 ​

OcrDecryptModel

DLL 调用 ​

int OcrDecryptModel(long ola, string packagePath, string password, string detParamOutPath, string detBinOutPath, string recParamOutPath, string recBinOutPath, string dictOutPath);

参数说明 ​

参数名类型说明
ola长整数型OLAPlug 对象指针。
packagePath字符串加密包路径。
password字符串解密密码。
detParamOutPath字符串检测 .param 输出路径。
detBinOutPath字符串检测 .bin 输出路径。
recParamOutPath字符串识别 .param 输出路径。
recBinOutPath字符串识别 .bin 输出路径。
dictOutPath字符串字典 .txt 输出路径；空 则跳过写出（即使包内含字典）。
