获取人体姿势关键点坐标

pose_data = [results.pose_landmarks.landmark[mp_pose.PoseLandmark.NOSE].x, results.pose_landmarks.landmark[mp_pose.PoseLandmark.NOSE].y, results.pose_landmarks.landmark[mp_pose.PoseLandmark.LEFT_SHOULDER].x, results.pose_landmarks.landmark[mp_pose.PoseLandmark.LEFT_SHOULDER].y, results.pose_landmarks.landmark[mp_pose.PoseLandmark.RIGHT_SHOULDER].x, results.pose_landmarks.landmark[mp_pose.PoseLandmark.RIGHT_SHOULDER].y, results.pose_landmarks.landmark[mp_pose.PoseLandmark.LEFT_ELBOW].x, results.pose_landmarks.landmark[mp_pose.PoseLandmark.LEFT_ELBOW].y, results.pose_landmarks.landmark[mp_pose.PoseLandmark.RIGHT_ELBOW].x, results.pose_landmarks.landmark[mp_pose.PoseLandmark.RIGHT_ELBOW].y, results.pose_landmarks.landmark[mp_pose.PoseLandmark.LEFT_WRIST].x, results.pose_landmarks.landmark[mp_pose.PoseLandmark.LEFT_WRIST].y, results.pose_landmarks.landmark[mp_pose.PoseLandmark.RIGHT_WRIST].x, results.pose_landmarks.landmark[mp_pose.PoseLandmark.RIGHT_WRIST].y, results.pose_landmarks.landmark[mp_pose.PoseLandmark.LEFT_HIP].x, results.pose_landmarks.landmark[mp_pose.PoseLandmark.LEFT_HIP].y, results.pose_landmarks.landmark[mp_pose.PoseLandmark.RIGHT_HIP].x, results.pose_landmarks.landmark[mp_pose.PoseLandmark.RIGHT_HIP].y, results.pose_landmarks.landmark[mp_pose.PoseLandmark.LEFT_KNEE].x, results.pose_landmarks.landmark[mp_pose.PoseLandmark.LEFT_KNEE].y, results.pose_landmarks.landmark[mp_pose.PoseLandmark.RIGHT_KNEE].x, results.pose_landmarks.landmark[mp_pose.PoseLandmark.RIGHT_KNEE].y, results.pose_landmarks.landmark[mp_pose.PoseLandmark.LEFT_ANKLE].x, results.pose_landmarks.landmark[mp_pose.PoseLandmark.LEFT_ANKLE].y, results.pose_landmarks.landmark[mp_pose.PoseLandmark.RIGHT_ANKLE].x, results.pose_landmarks.landmark[mp_pose.PoseLandmark.RIGHT_ANKLE].y] # 仅保留关键点

对于每个关键点，保存其x、y坐标和z坐标（如果存在）

for landmark in results.pose_landmarks.landmark: pose_data.append(landmark.x) pose_data.append(landmark.y) pose_data.append(landmark.z if landmark.z is not None else 0) # 保存所有关键点的坐标
