Thanks for your answer， The text of the picture is a test case ，the reason why i use this test case is that the actual text is produced by stm32 microcontroller . it produce text like "E2PROM ADDR6".Text itself may be some abnormal text language ... 'zth' is the library i have trained with Microsoft Yahei Standard font . I have used eng library which is Official word library file downloaded from the corresponding version of tesseract . It was not as accurate as I trained myself
