Representation of Car Body Shape using Standard Car Model and GUI Development for Car Body Shape Synthesis

Abstract

We have developed a tool to design car body shapes. It enables any user even with no experience and skill to design car body shapes interactively and easily. We report how we synthesize car body shapes by following process. Firstly, we create a database of existing cars and analyze all shapes in the database using Principal Component Analysis (PCA). Secondly we extract attributes that indicate the geometrical features of those car body shapes. The attributes are then mapped onto the Eigen space obtained as a result of analysis. We construct a GUI in which the distribution of the attributes on the Eigen space is visualized. By manipulating the weight of each attribute on our GUI, we can synthesize car body shapes which nobody has ever seen.
