Install Libraries
pip install opencv-python pytesseract pandas
Set Up Tesseract: Download and install Tesseract OCR, ensuring it's added to your system's PATH.
Capture Image: Use OpenCV to capture images from a camera and recognize text with Tesseract. Here's a basic code snippet:
python
Sao chép mã
import cv2
import pytesseract
import pandas as pd
pytesseract.pytesseract.tesseract_cmd = r'C:\Program Files\Tesseract-OCR\tesseract.exe'
cap = cv2.VideoCapture(0)
results =
while True:
ret, frame = cap.read()
if not ret:
break
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
text = pytesseract.image_to_string(gray)
if text.strip():
results.append(text.strip())
print(f'Recognized text: {text.strip()}')
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
df = pd.DataFrame(results, columns
df.to_csv('results.csv', index=False)
Run and Test: Execute the code, ensuring the label is clear and in focus for better recognition.
Enhancements:Experiment with image preprocessing techniques to improve recognition.
Consider optimizations for speed if needed.
