Methods for Measuring and Representing Automobile Occupant Posture
نویسندگان
چکیده
Many vehicle design and safety assessment applications use physical and virtual representations of vehicle occupants within the vehicle interior. Proper use of these human models requires accurate data concerning vehicle occupant posture and position. This paper presents techniques for characterizing vehicle occupant posture by measuring accessible body landmarks. The landmark locations are used to estimate joint locations that define a kinematic linkage representation of the human body. The resulting posture analysis techniques provide a unified method of measuring and reporting vehicle occupant postures that is suitable for use with both physical and virtual human models.

Automobile Occupant Posture Prediction for Use with Human Models
A new method of predicting automobile occupant posture is presented. The Cascade Prediction Model approach combines multiple independent predictions of key postural degrees of freedom with inverse kinematics guided by data-based heuristics. The new model, based on posture data collected in laboratory mockups and validated using data from actual vehicles, produces accurate posture predictions fo...
متن کاملModeling Vehicle Occupant Head and Head Restraint Positions
In January 2001, NHTSA issued a Notice of Proposed Rulemaking (NPRM) concerning the regulation of automobile head restraints in Federal Motor Vehicle Safety Standard (FMVSS) 202. This report presents analyses of occupant posture and position data that were conducted in preparation for comments from UMTRI on the NPRM. The focus of this report is on the potential impact of head restraint geometry...

متن کاملTo Appear in IEEE International Symposium on Intelligent Vehicles in Parma, Italy, June 2004. Occupant Posture Analysis using Reflectance and Stereo Images for “Smart” Airbag Deployment
Robust detection of vehicle occupant posture is necessary for intelligent airbag deployment. This paper presents a vision-based method of estimating the size, posture and pose of the occupant. Utilizing raw reflectance and stereo disparity images, this algorithm presents a mixed-mode approach to finding occupant features. Extensive experiments show the robustness of this mixed-mode method in id...
