AI总结:

针对标准A姿势扫描难以维持且不适用于伤障人群的问题,本文提出利用任意姿势的稀疏landmarks构建姿态无关特征并预测标准A姿势人体尺寸,性能可比密集几何方法且已开源。

摘要:

3D数字人体测量是研究如何从3D扫描中估计人体尺寸的学科。精确的人体尺寸是医疗行业中重要的健康指标,也是时尚、人体工程学和娱乐行业中的指导因素。测量流程包括以静态A姿势扫描整个受试者,并在扫描过程中保持该姿势,不呼吸也不移动。然而,在整个扫描过程中保持A姿势并不容易,扫描甚至可能持续几分钟。这一限制会影响扫描的最终质量,进而影响依赖密集几何数据的方法所获得的人体尺寸估计精度。此外,该限制使得无法为无法摆出A姿势的受试者(例如受伤或残障人士)开发数字人体测量方法。我们提出了一种方法,能够从任意姿势下获取的稀疏 landmarks 中获得人体尺寸。我们利用摆姿势受试者的稀疏 landmarks 构建姿态无关特征,并训练一个网络来预测按照标准A姿势测量得到的人体尺寸。我们表明,本方法取得了与在标准A姿势下使用密集几何信息的竞争方法相当的结果,同时具备仅使用稀疏 landmarks 即可从任意姿势估计人体尺寸的能力。最后,为解决开源3D人体测量方法的缺乏,我们在 https://github.com/DavidBoja/pose-independent-anthropometry 向研究社区提供本方法。

英文摘要:

3D digital anthropometry is the study of estimating human body measurements from 3D scans. Precise body measurements are important health indicators in the medical industry, and guiding factors in the fashion, ergonomic and entertainment industries. The measuring protocol consists of scanning the whole subject in the static A-pose, which is maintained without breathing or movement during the scanning process. However, the A-pose is not easy to maintain during the whole scanning process, which can last even up to a couple of minutes. This constraint affects the final quality of the scan, which in turn affects the accuracy of the estimated body measurements obtained from methods that rely on dense geometric data. Additionally, this constraint makes it impossible to develop a digital anthropometry method for subjects unable to assume the A-pose, such as those with injuries or disabilities. We propose a method that can obtain body measurements from sparse landmarks acquired in any pose. We make use of the sparse landmarks of the posed subject to create pose-independent features, and train a network to predict the body measurements as taken from the standard A-pose. We show that our method achieves comparable results to competing methods that use dense geometry in the standard A-pose, but has the capability of estimating the body measurements from any pose using sparse landmarks only. Finally, we address the lack of open-source 3D anthropometry methods by making our method available to the research community at https://github.com/DavidBoja/pose-independent-anthropometry.
