摘要：The precise measurement and feature information extraction of the biological macroscopic body shapes and surface micro-morphologies is an important precondition to obtain configuration resources directly in research of functionality biomimetics. The sharks with low-resistance body shape and scarfskin were selected as the typical example of creatures simultaneously with functional body shape and surface micro-morphology. Taking a frozen Carcharhinus brachyurous body and a piece of pretreated scarfskin as the biological samples, the measurement and reconstruction of its macroscopic body shape and surface micro-morphology were conducted respectively. The experimental results indicate that the measuring and reconstructing methods adopted can efficiently ensure the facticity and integrity of the measurement results, which contributes to the structure digitalization and feature information extraction of the biological prototypes. The study demonstrated in this paper may provide method references on information collection and data processing for design of bionic functional devices and interfaces.
