T3D UltraScan - A collapsible, ‘pop-up’ style, accurate full body low-cost 3D scanner

全身3D扫描仪价格昂贵(GB 100K+)，而且不容易携带，因为需要校准传感器、相机、照明和驱动器并将其连接到数百条电源/数据电缆上。在3D打印‘自拍’需求爆炸式增长的推动下，我们的目标是证明构建一种快速、低成本、便携式全身3D摄影测量扫描仪的可行性，将100-200个无线遥控器、相机和固态照明网络集成在一起。建立在“弹出”风格的框架之上，我们的目标是提高便携性/功能，并在不影响高清分辨率质量数据的情况下将成本降低到10,000 GB以下。将解决的主要挑战包括：(1)与无线传感器上的数据采集相关的错误，(2)处理、(3)分析、(4)转换、(5)同步性、(6)适应人体对象(呼吸、特征、移动)。需求：2014年拍摄了1万亿张2D“自拍”。Gartner(2014)预测，到2018年，3D自拍市场将从目前的4.18亿美元激增至17亿美元。预计到2020年，全球3D扫描仪硬件市场将达到49亿美元，年复合增长率为12.4%(Allied Research，2014)。

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).
