def ask():
    dirname = filedialog.askopenfile(
        initialdir='C:/Users/PC/Desktop',
        title='파일 선택',
        filetypes=(('png 파일','*.png'), ('jpg 파일', '*jpg'), ('모든 파일 보기', '*.*'))
    )
    filename = tkinter.filedialog.asksaveasfilename()
    Txt.configure(text='경로 :' + dirname.name)

def ocr():

In ask() you are setting to variables: dirname and filename.

These two variables are set as local variables by default (they will not be visible outside the ask() function). That's why you can't access them.

You can patch this by setting them to global:

#AFTER THE IMPORTS
filename = "some_default_filename.png"
dirname = "/some/default/path/"

#INSERT THIS AT THE BEGINNING OF ASK()
def ask():
    global filename
    global dirname

    filename = ..... #Your code

#YOU WILL BE ABLE TO ACCESS THEM TO OCR()
def ocr():
    #.......
    Image.open(dirname + filename)
    #.......

Note that if you don't need to edit the variable, you don't need to declare it global, python will assume that by default. You can still add global dirname and global filename if you wish, the code will run as well.
