这是我的代码，运行起来没有任何问题。但是，我不想手动从一个图像移动到另一个图像，因为我在文件夹中有超过2000个图像。我需要编辑什么来自动运行文件夹中的图像，并获得x，y，z坐标？

import cv2
import mediapipe as mp

path = glob.glob("")
for file in path:
    img = cv2.imread(file)
    mpDraw = mp.solutions.drawing_utils
    mpFaceMesh = mp.solutions.face_mesh
    facemesh = mpFaceMesh.FaceMesh(max_num_faces=1)
    drawSpec = mpDraw.DrawingSpec(thickness=1, circle_radius=2)
    rgb_image = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
    result = facemesh.process(rgb_image)
    if result.multi_face_landmarks:
        for faceLms in result.multi_face_landmarks:
            mpDraw.draw_landmarks(img, faceLms, mpFaceMesh.FACEMESH_CONTOURS,
            drawSpec, drawSpec)
            for lm in faceLms.landmark:
                print(lm)
    cv2.imshow("image", img)
    cv2.waitKey(0)
    cv2.destroyAllWindows()
