Question

我正在从事项目工作，并集成了card.io和tess-two库。我已经拥有这些图书馆，用于阅读国民身份证和其他身份证。在升级到ndk-14之前，一切运行良好。但升级后，我遇到了很多问题。我降级到ndk-13，但还有这些错误。这是我的日志：

关于libtess.so库的问题，但我不知道为什么？请帮助我，并询问更多细节。

以下是jni的一些基本代码：

初始化：

int res = api->Init(env->GetStringUTFChars(dataPath, 0), "aze");

if (res) {
    dmz_error_log("Could not initialize tesseract");
} else {
    dmz_debug_log("Initialized tesseract");
}

从卡片获取图片：

char *getCardNumberImage(cv::Mat cardImage) {
cv::Rect cropRect(kCreditCardTargetWidth * 76 / mmCardWidth,
                  kCreditCardTargetHeight * 14 / mmCardHeight,
                  kCreditCardTargetWidth * 24 / mmCardWidth,
                  kCreditCardTargetHeight * 4 / mmCardHeight);

api->SetVariable("tessedit_char_whitelist",
                 "0123456789");

return getOCRText(cardImage(cropRect));
}

从tesseract获得结果：

char *getOCRText(cv::Mat image) {
api->SetImage((uchar *) image.data, image.size().width, image.size().height,
              image.channels(), image.step1());
// Get OCR result
char *outText = api->GetUTF8Text();
dmz_debug_log("TEXT %s", outText);
return outText;
}

I当我使用3.05训练的训练数据时效果很好，但是当我使用训练有4.00的数据时，它会给我这样的错误。我的tesseract版本是4.00 Alpha。

升级ndk-14后，共享库会出现问题
