Tesseract Api crashing

Question

Ich benutze Tesseract. Ich verwende 2 Warteschlangen, um Bild in Text zu konvertieren. Wenn ich mehrere Prozesse ausführe, schlägt meine Tesseract API fehl und gibt einen schwerwiegenden Fehler.

Fehler 1 :::

Answer 1

ich ähnliches Problem habe. Es scheint, dass das Problem weg ist, wenn Sie stattdessen doOCR() mit einem File als Eingabeparameter anstelle von BufferedImage anwenden.
