Example Embodiment

[0041] Such as figure 1 As shown, the three-dimensional human body size non-contact measurement system (see ZL 200510013085.8 and ZL 200810054313.X) used in the present invention mainly includes: measurement platform, mechanical device, point cloud data acquisition device, motion control device and point cloud Data processing device.

[0042] Now describe the measurement steps and the requirements of each step:

[0043] When measuring the body size, a dynamic calibration target is required to calibrate the measurement system. For the same measurement system, the camera calibration only needs to be done once, without repeated work.

[0044] (1) The measured human body stands on the measuring platform in a standard standing posture, keeping the posture still;

[0045] Measurement requirements: The measurement system is to receive the laser scattered light on the surface of the object to be measured for measurement. The measurement environment is required to be a dark room as much as po...

Abstract

The invention relates to a method for automatically measuring human body dimensions on the basis of three-dimensional point cloud data. According to three-dimensional human body point cloud data acquired by a laser three-dimensional color human body scanner developed on the basis of independent innovation, the original three-dimensional point cloud data is denoised and the like; and then human body dimensions, which are required by costume design, model measurement and the like and comprise height, body measurements and curve length, are acquired by automatically fetching human body characteristic points and characteristic sections. A measuring system adopted by the invention acquires three-dimensional human body outline data, which can reflect the body form of the human body best, by directly scanning the human body; joint points and outline convex points of the human body can be automatically fetched by a maximum and minimum measurement method and a most convex and concave point method; and characteristics and dimensions of the human body longitudinal sections and cross sections can be directly acquired. The method is convenient in operation, high in speed, high in measuring precision, high in repeatability and suitable for human body measurement on a large scale.

Description

technical field [0001] The invention belongs to the technical field of human body measurement, in particular relates to the measurement of human body size, in particular to a non-contact automatic measurement method for human body size. Background technique [0002] Anthropometry is a key part of modern economy and user-centered design, such as clothing design, clothing cutting, model body measurement and other fields to obtain the precise shape of the human body is one of the basic premise of the next work, and now more and more Many people are aware of the important role of anthropometric data in improving the quality of product design and workspace design. In the past decade, the maturity of 3D laser scanning technology has made it possible to accurately measure and quickly calculate the size of the human body. Currently The human body size measurement data collection established by the three-dimensional laser scanning method is widely used in the fields of human body sha...
