如何從Python訪問Tesseract的命令行？

Question

我正在使用Python來做一些處理，並且我需要使用Tesseract進行OCR。有沒有一種方法可以讓我從蟒蛇，鍵入：

「正方體--tessdata-目錄的/ usr /股imagename outputbase -l工程-psm 3」

進入命令行以某種方式或等值？

謝謝！

Answer 1

請參閱下面的示例。

import subprocess 

p = subprocess.Popen(["ping", "localhost"], stdout=subprocess.PIPE) 
output, err = p.communicate() 
print output 

輸出：

Pinging w10-PC [::1] with 32 bytes of data: 
Reply from ::1: time<1ms 
Reply from ::1: time<1ms 
Reply from ::1: time<1ms 
Reply from ::1: time<1ms 

Ping statistics for ::1: 
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), 
Approximate round trip times in milli-seconds: 
    Minimum = 0ms, Maximum = 0ms, Average = 0ms 

更換["ping", "localhost"]在例如與

["tesseract", "--tessdata-dir", "/usr/share", "imagename", "outputbase", "-l", "eng", "-psm", "3"].
