推荐答案

据我了解，你可以在不的tesseract白名单的话。您可以使用以下code段只有白名单字符和数字

As far as I understand you cannot whitelist words in tesseract. You can only whitelist characters and digits using the following code snippet

tessBaseAPI.setVariable(TessBaseAPI.VAR_CHAR_WHITELIST,\"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmopqrstuvwxyz0123456789%,\");

tessBaseAPI.setVariable(TessBaseAPI.VAR_CHAR_WHITELIST,"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmopqrstuvwxyz0123456789%,");

使用tessBaseAPI.init初始化的tesseract后（...，...）;

after initializing tesseract using tessBaseAPI.init(...,...);
