Panoramic shape and deformation measurements of human skin in vivo may provide important information for biomechanical analysis, exercise guidance and medical diagnosis. This work proposes the application of an advanced mirror-assisted multi-view digital image correlation (DIC) method for dynamic measurements of 360-deg shape and deformation of human body parts in vivo. The main advantage of this method consists in its capabilities to perform full-panoramic non-contact measurements with a single pair of synchronized cameras and two planar mirrors thus representing a lean yet effective alternative to conventional multi-camera DIC systems in ‘surrounding’ configuration. We demonstrate the capabilities of this method by measuring the full-panoramic shape of a plastic human head, the deformation of a woman face and the principal strain distribution over the full-360-deg surface of a forearm during fist clenching. The applications of this method can be the most disparate but, given the possibility to determine the full-field strains and derived information (e.g. skin tension lines), we envisage a great potential for the study of skin biomechanics in vivo.

人体皮肤在体内的全景形状和变形测量可能为生物力学分析，运动指导和医学诊断提供重要信息。这项工作提出了一种先进的镜像辅助多视图数字图像相关性（DIC）方法在体内360度变形和人体部位变形的动态测量中的应用。该方法的主要优点在于它具有使用一对同步摄像机和两个平面镜执行全全景非接触式测量的能力，因此代表了传统的多摄像机DIC系统“环绕”配置的精简而有效的替代方案。我们通过测量塑料人头的全景形状，女人脸的变形以及握拳过程中前臂全360度表面上的主要应变分布来证明这种方法的功能。这种方法的应用可能是最不同的，但是，鉴于确定全视野应变和衍生信息（例如皮肤张力线）的可能性，我们认为在体内研究皮肤生物力学的潜力很大。
