我正在使用 tensorflow 制作剪刀石頭布游戲，用戶可以通過(guò)網(wǎng)絡(luò)攝像頭玩電腦，但網(wǎng)絡(luò)攝像頭圖像太小，如下所示：屏幕截圖這是我使用 OpenCV 的片段：cap = cv2.VideoCapture(0)prev_move = Nonewhile True:    ret, frame = cap.read()    if not ret:        continue    # rectangle for user to play    cv2.rectangle(frame, (100, 100), (500, 500), (255, 255, 255), 2)    # rectangle for computer to play    cv2.rectangle(frame, (800, 100), (1200, 500), (255, 255, 255), 2)    # extract the region of image within the user rectangle    roi = frame[100:500, 100:500]    img = cv2.cvtColor(roi, cv2.COLOR_BGR2RGB)    img = cv2.resize(img, (227, 227))    # predict the move made    pred = model.predict(np.array([img]))    move_code = np.argmax(pred[0])    user_move_name = mapper(move_code)    # predict the winner (human vs computer)    if prev_move != user_move_name:        if user_move_name != "none":            computer_move_name = choice(['rock', 'paper', 'scissors'])            winner = calculate_winner(user_move_name, computer_move_name)        else:            computer_move_name = "none"            winner = "Waiting..."    prev_move = user_move_name    # display the information    font = cv2.FONT_HERSHEY_SIMPLEX    cv2.putText(frame, "Your Move: " + user_move_name,                (50, 50), font, 1.2, (255, 255, 255), 2, cv2.LINE_AA)    cv2.putText(frame, "Computer's Move: " + computer_move_name,                (750, 50), font, 1.2, (255, 255, 255), 2, cv2.LINE_AA)    cv2.putText(frame, "Winner: " + winner,                (400, 600), font, 2, (0, 0, 255), 4, cv2.LINE_AA)    if computer_move_name != "none":        icon = cv2.imread(            "{}.png".format(computer_move_name))        icon = cv2.resize(icon, (400, 400))        frame[100:500, 800:1200] = icon    cv2.imshow("Rock Paper Scissors", frame)    k = cv2.waitKey(10)    if k == ord('q'):        breakcap.release()cv2.destroyAllWindows()我的網(wǎng)絡(luò)攝像頭有問(wèn)題嗎？我嘗試調(diào)整框架大小，但它不起作用。
