基于视频的眼部和姿势指标在自然驾驶中的应用：按年龄组和性别进行探索性比较

This exploratory observational study describes video-derived ocular and postural indicators during naturalistic driving in 30 volunteers, comprising 16 men and 14 women aged 25–50 years. Participants completed one daytime driving session in their own vehicles. Cabin-facing and forward-facing cameras recorded video at 1920 × 1080 pixels and a standardised frame rate of 30 frames per second. MATLAB-based processing included face and eye-region detection, blink analysis, and image-based posture assessment. The manuscript reports descriptive comparisons by gender and by age group, distinguishing y
