英文摘要：

Quantitative analysis of geometrical configuration of dung beetles is important to the biomimetic design of the configuration of some mechanisms. The digital point clouds of geometrical surfaces of dung beetle Copris ochus Motschulsky were obtained through measuring with a 3D scanner. The point clouds （data） were processed by such functions as wiping off noise data, sampling, smoothing and putting together for the data using the software of reverse engineering. The reconstruction of 3D geometrical surfaces of dung beetle Copris ochus Motschulsky were realized through such processing procedures as gridding of the point data, extraction of surface feature, subarea of data, partition of surfaces and directly fitting surface partition. This work will provide a foundation for quantitative analysis of the characters of geometrical morphology and configuration of dung beetles Copris ochus Motschulsky and other beetles and their biomimetic engineering applications in terrain machines.
