actual_tessdata_num_entries_ <= TESSDATA_NUM_ENTRIES:Error:Assert failed:in file .\tessdatamanager.cpp, line 55
Java Result: 1

Answer 1

发生错误是因为 C++ 代码引发了异常。 Java 不能“包装”那些。

抛出异常是因为违反了以下断言：

actual_tessdata_num_entries_ <= TESSDATA_NUM_ENTRIES

常量在tessdatamanager.h 中定义。它与您需要的数据文件有关。确保您使用的数据文件与您的 tesseract 版本匹配。
