AttributeError: module 'mediapipe.python.solutions.holistic' has no attribute 'FACE_CONNECTIONS'

报错信息"AttributeError: module 'mediapipe.python.solutions.holistic' has no attribute 'FACE_CONNECTIONS'"是由于MediaPipe库在某个版本的更新中将'FACE_CONNECTIONS'改为了'FACEMESH_CONTOURS'所致。解决这个问题的方法是将代码中的'FACE_CONNECTIONS'改为'FACEMESH_CONTOURS'即可正常运行。

AttributeError: module 'mediapipe.python.solutions.holistic' has no attribute 'FaceLandmark'

这个错误是因为在mediapipe的版本更新中，FaceLandmark的位置发生了变化。在新版本的mediapipe中，FaceLandmark位于mediapipe.python.solutions.face_mesh.FaceMeshLandmark中。

以下是使用新版本mediapipe获取摄像头识别手部、嘴巴、眼睛并分别截取三个区域的Python代码：

import cv2
import mediapipe as mp

# 初始化mediapipe的Hand, Face和Holistic模型
mp_hands = mp.solutions.hands
mp_face = mp.solutions.face_detection
mp_holistic = mp.solutions.holistic
mp_face_mesh = mp.solutions.face_mesh

# 初始化mediapipe的DrawingUtils模块
mp_drawing = mp.solutions.drawing_utils

# 初始化摄像头
cap = cv2.VideoCapture(0)

# 设置截取区域的大小和位置
hand_area = (100, 100, 300, 300) # (x, y, w, h)
face_area = (100, 100, 300, 300) # (x, y, w, h)
eye_area = (100, 100, 300, 300) # (x, y, w, h)

# 用于标记是否检测到手部、脸部和眼睛
hand_detected = False
face_detected = False
eye_detected = False

# 初始化Hand、Face和Holistic模型
with mp_hands.Hands() as hands, mp_face.FaceDetection() as face_detection, mp_holistic.Holistic() as holistic, mp_face_mesh.FaceMesh() as face_mesh:
    while True:
        # 从摄像头读取一帧图像
        ret, image = cap.read()
        if not ret:
            break

        # 将图像转换为RGB格式
        image = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)

        # 检测手部
        results_hands = hands.process(image)
        if results_hands.multi_hand_landmarks:
            # 获取手部关键点坐标
            hand_landmarks = results_hands.multi_hand_landmarks[0]
            # 绘制手部关键点
            mp_drawing.draw_landmarks(image, hand_landmarks, mp_hands.HAND_CONNECTIONS)
            # 截取手部区域图片
            x, y, w, h = hand_area
            hand_image = image[y:y+h, x:x+w]
            hand_detected = True
        
        # 检测脸部
        results_face = face_detection.process(image)
        if results_face.detections:
            # 获取脸部关键点坐标
            face_landmarks = results_face.detections[0].location_data.relative_bounding_box
            # 绘制脸部矩形框
            h, w, _ = image.shape
            x, y, w, h = int(face_landmarks.xmin * w), int(face_landmarks.ymin * h), int(face_landmarks.width * w), int(face_landmarks.height * h)
            cv2.rectangle(image, (x, y), (x+w, y+h), (0, 255, 0), 2)
            # 截取脸部区域图片
            x, y, w, h = face_area
            face_image = image[y:y+h, x:x+w]
            face_detected = True
        
        # 检测眼睛
        results_holistic = holistic.process(image)
        if results_holistic.face_landmarks:
            # 获取眼睛关键点坐标
            left_eye = results_holistic.face_landmarks.landmark[mp_holistic.FACE_CONNECTIONS['left_eye'][0]]
            right_eye = results_holistic.face_landmarks.landmark[mp_holistic.FACE_CONNECTIONS['right_eye'][0]]
            # 绘制眼睛关键点
            mp_drawing.draw_landmarks(image, [left_eye, right_eye], mp_holistic.FACE_CONNECTIONS)
            # 截取眼睛区域图片
            x, y, w, h = eye_area
            eye_image = image[y:y+h, x:x+w]
            eye_detected = True
        
        # 检测嘴巴
        results_face_mesh = face_mesh.process(image)
        if results_face_mesh.multi_face_landmarks:
            # 获取嘴巴关键点坐标
            mouth_landmarks = results_face_mesh.multi_face_landmarks[0].landmark[mp_face_mesh.FaceMeshLandmark.MOUTH_TOP]
            # 绘制嘴巴关键点
            mp_drawing.draw_landmarks(image, [mouth_landmarks], mp_face_mesh.FACEMESH_CONTOURS)
            # 截取嘴巴区域图片
            x, y, w, h = face_area
            mouth_image = image[y:y+h, x:x+w]
            mouth_detected = True

        # 显示图像
        cv2.imshow('MediaPipe', image)

        # 检查是否已经检测到手部、脸部、眼睛和嘴巴，如果是则退出循环
        if hand_detected and face_detected and eye_detected and mouth_detected:
            break

        # 按下q键退出程序
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break

# 释放摄像头并关闭所有窗口
cap.release()
cv2.destroyAllWindows()

在这个新的代码中，我们使用了mediapipe.python.solutions.face_mesh.FaceMeshLandmark来获取嘴巴的关键点坐标，并使用mediapipe.python.solutions.face_mesh.FACEMESH_CONTOURS绘制嘴巴的轮廓。

AttributeError: module 'mediapipe.python.solutions.face_mesh' has no attribute 'FACE_CONNECTIONS'

当你在使用MediaPipe库中的人脸面部检测功能时，出现了AttributeError: module 'mediapipe.python.solutions.face_mesh' has no attribute 'FACE_CONNECTIONS'的错误。根据资料，这个错误通常是由于MediaPipe库的更新导致的。在某个版本的更新中，FACE_CONNECTIONS被改为了FACEMESH_CONTOURS。

要解决这个问题，你需要将你的代码中的FACE_CONNECTIONS改为FACEMESH_CONTOURS。这样更改后，你的代码应该可以正常运行了。请确保你的MediaPipe库是最新版本，以确保你的代码与库的版本兼容。

总结起来，解决AttributeError: module 'mediapipe.python.solutions.face_mesh' has no attribute 'FACE_CONNECTIONS'的方法是将代码中的FACE_CONNECTIONS改为FACEMESH_CONTOURS，并确保使用的MediaPipe库是最新版本。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
