字符串匹配返回不匹配的默认值
String matching returning a default value for not a match
我正在从 'terms' 列表的字典 d['text'] 值中搜索来自 pytesseract.image_to_data 的一组特定字符串值。我写了一个函数 check() ，它 return 是匹配的正确坐标，但是对于所有其他不匹配的搜索，它 return 是默认坐标（['left'、'top'、'width'、'height']).
我之所以使用 split，是因为字符串是这样的：["Print Name of Subscriber", "Investor's Name"]。
在 pytesseract.image_to_data 中，d['text'] 的形式为：['Print'、'Name'、'of'、'Subscriber'].
pytesseract.image_to_data returns 带有 data.keys() 的图像字典：['level', 'page_num', 'block_num', 'par_num', 'line_num', 'word_num', 'left', 'top', 'width', 'height', 'conf', 'text'].
我只关心 'text' 和坐标：'left'、'top'、'width'、'height'。它应该 return None 当没有匹配时，它是 returning 默认坐标。
代码：
import pytesseract
from pytesseract import Output
import cv2
image_path='image/out.jpg'
terms=["Print Name of Subscriber", "Investor's Name", "Name of Investor"]
image = cv2.imread(image_path)
d = pytesseract.image_to_data(image, output_type=Output.DICT)
def check(word, d):
phrases = [w for w in word.split()]
for i, t in enumerate(d['text']):
to_match = d['text'][i+1: i+1+len(phrases)]
if all(p == m for p,m in zip(phrases, to_match)):
return [*map(lambda x:d[x][i], ['left', 'top', 'width', 'height'])]
for term in terms:
check=check(term, d)
print(check)
当最后一项匹配时，它 returns: [93, 975, 148, 20] 正确。
对于图像上没有匹配项的所有其他条目，它 returns: [151, 2078, 170, 8] 默认。我在函数的 else 语句中尝试 returning None，然后它 return None 也用于所有匹配项。
d 的值：

我正在从 'terms' 列表的字典 d['text'] 值中搜索来自 pytesseract.image_to_data 的一组特定字符串值。我写了一个函数 check() ，它 return 是匹配的正确坐标，但是对于所有其他不匹配的搜索，它 return 是默认坐标（['left'、'top'、'width'、'height']).
我之所以使用 split，是因为字符串是这样的：["Print Name of Subscriber", "Investor's Name"]。 在 pytesseract.image_to_data 中，d['text'] 的形式为：['Print'、'Name'、'of'、'Subscriber'].
pytesseract.image_to_data returns 带有 data.keys() 的图像字典：['level', 'page_num', 'block_num', 'par_num', 'line_num', 'word_num', 'left', 'top', 'width', 'height', 'conf', 'text']. 我只关心 'text' 和坐标：'left'、'top'、'width'、'height'。它应该 return None 当没有匹配时，它是 returning 默认坐标。
代码：
import pytesseract
from pytesseract import Output
import cv2
image_path='image/out.jpg'
terms=["Print Name of Subscriber", "Investor's Name", "Name of Investor"]
image = cv2.imread(image_path)
d = pytesseract.image_to_data(image, output_type=Output.DICT)
def check(word, d):
phrases = [w for w in word.split()]
for i, t in enumerate(d['text']):
to_match = d['text'][i+1: i+1+len(phrases)]
if all(p == m for p,m in zip(phrases, to_match)):
return [*map(lambda x:d[x][i], ['left', 'top', 'width', 'height'])]
for term in terms:
check=check(term, d)
print(check)
当最后一项匹配时，它 returns: [93, 975, 148, 20] 正确。 对于图像上没有匹配项的所有其他条目，它 returns: [151, 2078, 170, 8] 默认。我在函数的 else 语句中尝试 returning None，然后它 return None 也用于所有匹配项。
