The invention discloses a 
waist-
abdomen-buttock 
body type classification method and a measuring device based on a feature distance set. The measuring device is composed of a collection device and special measuring overalls. The collection device includes a base, a camera pillar, a camera and a telescopic pole, and  There is a positioning 
footprint at the center of the special measuring overalls, a 
grid pattern is printed on the special measuring overalls, a first marking line is set at the 
waist of the special measuring overalls, a second marking line is set at the 
crotch of the special measuring overalls, the straps  Velcro is sewn on.  With the help of this measuring device, the feature distance set reflecting the three-dimensional shape of the 
human body can be extracted quickly, accurately and simply, and the 
waist and 
abdomen body types can be classified, so as to provide a theoretical basis for the design of bottoms of different body types, so that the waist, 
abdomen and hips of the bottoms can be closely matched.  Combined with the characteristics of the 
human body shape, the fit and comfort of the bottoms are improved.
