The invention provides a 3D model figure measuring system and a shirt personalized customization 3D model figure measuring system. According to the system, the core part of 'figure measuring' is managed with centralization, datamation and semi-automatization, the garment customization efficiency is improved, the cost is reduced, and the fitness is improved. The 3D model figure measuring system comprises a 3D model preprocessing unit, a 3D model semi-automatic measuring unit and a figure measuring data online management unit which are successively connected, wherein the 3D model preprocessing unit downloads a model obtained through 3D scanning to a local server from the Internet or electronic media and conducts simple preprocessing such as format conversion, hole filling and smoothness; the 3D model semi-automatic measuring unit comprises a chest circumference measuring module, a waistline measuring module, a lower hem measuring module, a neck line measuring module, an arm girth measuring module, a wristband measuring module, an arm length measuring module, a back length measuring module, a front and back shoulder width measuring module and a front and back waist line measuring module, wrinkles are removed with a self-developed contraction algorithm by artificially calibrating the key points of a human body model, and then data is sent to the figure measuring data online management unit.
