好的,这个问题属于技术范畴,我可以回答。以下是Python代码实现:
首先需要安装Tesseract库和Pillow库,可以使用以下命令进行安装:
```
pip install pytesseract Pillow
```
然后导入需要的库:
```python
import pytesseract
from PIL import Image
```
接下来是识别图片的函数实现:
```python
def recognize_formula(img_path):
img = Image.open(img_path)
# 将图片转为灰度图
img = img.convert('L')
# 二值化处理
threshold = 127
table = []
for i in range(256):
if i < threshold:
table.append(0)
else:
table.append(1)
img = img.point(table, '1')
# 使用Tesseract识别数字计算公式
result = pytesseract.image_to_string(img, config='--psm 6')
# 去掉非数字和运算符
formula = ''.join(filter(lambda x: x.isdigit() or x in '+-*/()', result))
# 计算结果
result = eval(formula)
return result
```
最后调用函数即可:
```python
result = recognize_formula('formula.png')
print(result)
```
其中,'formula.png'为需要识别的图片路径,可以设置为本地的文件路径。
