Abstract:
Objective:To provide accurate eye position data for the system design of helmet mounted display by studying the eye position distribution and anthropometric items of pilots' head and face.Methods:The head and face data of 372 Chinese male fighter pilots were captured by a non-contact 3D scanning system to build cloud models. By noise cutting and mending processing each head and face model was built with same template mesh and unified anatomical coordinate system. The eye position design was defined according to monocular or binocular display. The positions (core of pupils) of left and right eyes and 12 anthropometric items were calculated from the 3D models.Results:The database of 372 fighter pilots′ head and face 3D models was established and it included 12 anthropometric items such as the coordinates of left and right eyes position, inter pupillary distance and vertex-pupil height.Conclusions:Based on 3D scanning technology, the distribution of eye locations (designed eye position and eye box) of pilots were built under the human head anatomical coordinate system and related anthropometric items of head and face are obtained, which could be used as the data foundation for designing pilot′s helmet mounted display system.
