I use this programmer to use camera to moniter and get what happened on these two oled led screens. In calling tesseract api module, i use tesseract like this: ## var engine = new TesseractEngine(@"./tessdata", "zth", EngineMode.LstmOnly); var page = engine.Process(img, PageSegMode.SingleBlock); string result = page.GetText(); ## the "zth" is the library file i trained by LSTM and EngineMode is similar to CLI's "--oem 1" "PageSegMode.SingleBlock" is CLI's "--PSM 8" 在2021年9月16日星期四 UTC+8 下午2:03:28<zdenop> 写道：
