VIRTUAL TESTING MODEL FOR USE IN SIMULATED AERODYNAMIC TESTING

摘要

A method for developing a virtual testing model of a subject for use in simulated aerodynamic testing comprises providing a computer generated generic 3D mesh of the subject, identifying a dimension of the subject and at least one reference point on the subject, imaging the subject to develop point cloud data representing at least the subject's outer surface and adapting the generic 3D mesh to the subject. The generic 3D mesh is adapted by modifying it to have a corresponding dimension and at least one corresponding reference point, and applying at least a portion of the point cloud data from the imaged subject's outer surface at selected locations to scale the generic 3D mesh to correspond to the subject, thereby developing the virtual testing model specific to the subject.

1. A method for developing a virtual testing model of a subject for use in simulated aerodynamic testing, comprising:
providing a computer generated generic 3D mesh of the subject; identifying a dimension of the subject and at least one reference point on the subject; imaging the subject to develop point cloud data representing at least the subject's outer surface; adapting the generic 3D mesh to the subject by modifying the generic 3D mesh to have a corresponding dimension and at least one corresponding reference point, the corresponding dimension corresponding to the identified dimension of the subject and the at least one corresponding reference point corresponding to the identified at least one reference point of the subject; modifying the generic 3D mesh further by applying at least a portion of the point cloud data from the imaged subject's outer surface at selected locations to scale the generic 3D mesh to correspond to the subject, thereby developing the virtual testing model specific to the subject.
