Full body 3D scanners are expensive (£100K+), and not easily portable owing to the need to calibrate and connect sensors, cameras, lighting and drives to hundreds of power/data cables. Triggered by explosion in demand for 3D Printed ‘Selfies’ we aim to prove the feasibility of building a fast, low-cost, portable full body 3D photogrammetric scanner, integrating a network of 100-200 wireless remote sensors, cameras, and solid state lighting. Built on a ‘pop-up’ style framework, we aim to improve portability/functionality and drive cost to below £10,000 without compromising HD resolution quality data. Key challenges that will be addressed include: (1) errors associated with data acquisition over wireless sensors, (2) processing, (3) analysis, (4) conversion, (5) synchronicity, (6) accommodating human subject (breathing, features, moving). Demand: 1Trillion 2D ‘selfies’ taken in 2014. Gartner (2014) forecast 3D Selfies market will explode from its current $418mn USD to $1.7bn USD by 2018. The global 3D scanner hardware market is forecast to reach $4.9 billion by 2020, registering a CAGR of 12.4% (Allied Research, 2014).

全身 3D 扫描仪价格昂贵（10 万英镑以上），而且由于需要校准传感器、相机、照明和驱动器并将其连接到数百条电源/数据电缆，因此不易携带。由于 3D 打印“自拍”的需求激增，我们的目标是证明构建快速、低成本、便携式全身 3D 摄影测量扫描仪的可行性，该扫描仪集成了由 100-200 个无线远程传感器、相机和固态照明组成的网络。我们建立在“弹出”式框架的基础上，旨在提高可移植性/功能性，并将成本降低至 10,000 英镑以下，同时不影响高清分辨率质量数据。将解决的主要挑战包括：(1) 与无线传感器数据采集相关的错误，(2) 处理，(3) 分析，(4) 转换，(5) 同步性，(6) 适应人类主体（呼吸、特征、移动）。需求：2014 年拍摄了 1 万亿张 2D“自拍”。Gartner (2014) 预测 3D 自拍市场将从目前的 4.18 亿美元激增至 2018 年的 17 亿美元。全球 3D 扫描仪硬件市场预计到 2020 年将达到 49 亿美元，复合年增长率为 12.4%（Allied Research，2014）。
