今天我想要偵測到我的物件後，可以原頁面跳轉到product_page.html。但現在是有偵測到也有掃描紀錄，但就是不會跳轉而且偵測的部分就直接卡住，我vscode裡面也沒有顯示錯誤。而我的html也都丟在資料夾templates內了
我掃描的頁面python
from flask import Flask, render_template, Response, request, redirect
import cv2
import numpy as np
import torch
import time
import webbrowser
app = Flask(__name__)
model = torch.hub.load('ultralytics/yolov5', 'custom', path='best.pt', force_reload=True)
cap = cv2.VideoCapture(0)
height, width, _ = cap.read()[1].shape
baseline = height // 2 + 100
# 存儲已跳轉過的網頁
opened_links = []
video_paused = False
detected_object_names = [] # 使用列表來存儲檢測到的物體名稱
def detect_objects():
while cap.isOpened():
if video_paused:
time.sleep(0.1)
continue
success, frame = cap.read()
if not success:
print("Ignoring empty camera frame.")
continue
frame = cv2.resize(frame, (800, 480))
results = model(frame)
detected_objects = results.xyxy[0]
cv2.line(frame, (0, baseline), (width, baseline), (0, 0, 255), thickness=2)
for obj in detected_objects:
obj_class = int(obj[-1])
if obj_class in [0, 1, 2]:
obj_center_x = (obj[0] + obj[2]) / 2 + 100
obj_center_y = (obj[1] + obj[3]) / 2 + 100
if obj_center_y > baseline:
link_url = ""
if obj_class == 0:
link_url = "/product_page"
detected_object_name = "柚香"
elif obj_class == 1:
link_url = "/product_page"
detected_object_name = "福樂"
elif obj_class == 2:
link_url = "/product_page"
detected_object_name = "美祿"
if link_url not in opened_links:
opened_links.append(link_url)
detected_object_names.append(detected_object_name)
return redirect(link_url)
img_bytes = cv2.imencode('.jpg', np.squeeze(results.render()))[1].tobytes()
yield (b'--frame\r\n'
b'Content-Type: image/jpeg\r\n\r\n' + img_bytes + b'\r\n')
@app.route('/')

return render_template('home.html')

def product_page():
return render_template('product_page.html')
