Python 使用PyteSeract执行OCR时出错

Python 使用PyteSeract执行OCR时出错,python,python-3.x,python-tesseract,Python,Python 3.x,Python Tesseract,我正在使用Pycharm社区并尝试安装tesseract for OCR。 我的代码如下: FileNotFoundError: [WinError 2] The system cannot find the file specified. During handling of the above exception, another exception occurred: pytesseract.pytesseract.TesseractNotFoundError: tesseract is

我正在使用Pycharm社区并尝试安装tesseract for OCR。 我的代码如下:

FileNotFoundError: [WinError 2] The system cannot find the file specified.
During handling of the above exception, another exception occurred: pytesseract.pytesseract.TesseractNotFoundError: tesseract is not installed or it's not in your path.  

是的,我只换了一行就把问题解决了

我们必须提供pytesseract exe的可执行路径

pytesseract.pytesseract.tesseract_cmd='C:\Program Files(x86)\tesseract OCR\tesseract.exe'

代码如下: def get_字符串(img_路径): #用opencv读取图像 img=cv2.imread(img\u路径) #变灰 img=cv2.cvt颜色(img,cv2.COLOR\u bgr2灰色) #应用膨胀和腐蚀去除一些噪音 内核=np.ones((1,1),np.uint8) img=cv2.deflate(img,内核,迭代次数=1) img=cv2.腐蚀(img,内核,迭代次数=1) #去除噪声后写入图像 imwrite(src_path+“removed_noise.png”,img) #应用阈值以获得只有黑白的图像 #img=cv2.adaptiveThreshold(img,255,cv2.ADAPTIVE_THRESH_GAUSSIAN_C,cv2.THRESH_BINARY,31,2) #在应用opencv后编写图像以执行一些。。。 imwrite(src_path+“thres.png”,img) #使用tesseract for python识别文本 pytesseract.pytesseract.tesseract_cmd='C:\\Program Files(x86)\\tesseract OCR\\tesseract.exe' 结果=pytesseract.image\u to\u字符串(image.open(src\u路径+“thres.png”)) #删除模板文件 #操作系统删除(临时) 返回结果

欢迎来到stackoverflow,请阅读。它将帮助你准备一个好问题,并有可能得到正确的答案。我也添加了名为TesseRactid的新环境变量。通过pacmanWelcome to stackoverflow,请阅读。它将帮助你准备一个好问题,并有可能得到正确的答案。在pacman的帮助下,我还添加了名为TesseRactid的新环境变量安装了tesseract包
