推荐答案
如果您使用的是tesseract 3(我以为您是).您必须重建eng.trainddata文件我打算完全替换word-dawg文件以尝试获得更好的结果(即-我检测到的单词始终相同).
if you're using tesseract 3 (which I assume you are).You'll have to rebuild your eng.trainddata fileI intended to replace the word-dawg file completely to try to get better results (ie - the words i'm detecting are always the same).
编译tesseract时，在培训目录中将需要Combine_tessdata和wordlist2dawg可执行文件.
you'll need combine_tessdata and wordlist2dawg executables in the training directory when you compile tesseract.

解压缩所有内容(我这样做只是为了备份eng.word-dawg，稍后您还需要unicharset)
unpack everything (i did this just to back up my eng.word-dawg, you'll also need the unicharset later)
./combine_tessdata -u eng.traineddata
创建单词列表的文本文件(wordlistfile)
create a textfile of your wordlist (wordlistfile)
创建eng.word-dawg
create a eng.word-dawg
./wordlist2dawg wordlistfile eng.word-dawg trainingdat_backup/.unicharset
替换word-dawg文件
replace the word-dawg file
./combine_tessdata -o eng.traineddata eng.word-dawg
应该的.
