Porting CAESAR Data as an ERL Human Body Model

In this paper we present a method for converting the CAESAR full body scanned data into human body models for use in the ERL design software. The ERL software is a comprehensive interior automobile design tool, used in design or evaluation. The 3D CAD occupants in ERL were generated from anatomical cross sections at comparable landmarks and spinal shapes. Skeletal landmarks in the CAESAR data are used to establish segmental coordinates from which cross-sections are defined. The anatomical cross sections are used to re-generate the external shape of the body. Additional skeletal landmarks are calculated using regression equations. Segmental mass distributions are calculated based on segmental volume.
