Seeing more – long-range, high-definition, moving 3D imaging in daylight

该项目将使Aralia Systems能够开发3D成像技术，用于在白天向外移动非常远距离(100米)的物体。这目前是不可能的。该团队此前已经演示了如何通过控制现有的近红外照明器和摄像机网络，使用光度控制立体(PS)，一种从阴影形成形状的技术，可以在室内环境中捕获高分辨率的运动3D图像。该项目是及时的，因为它将探索利用相机传感器技术中一项令人兴奋的最新发展的可行性，即黑硅。通过使用受控的LED和眼睛安全的激光，黑硅成像技术可以在太阳光谱的凹陷区域(940 Nm)捕获人工照明的图像。这允许使用PS来创建信息丰富的3D热点，这些热点可以放置在受监控环境中的任何地方。这一发展可能会使户外移动3D成像的使用发生一大变化。这将使Aralia能够在监视应用程序中开发增强的可视化和威胁检测软件。

This project will enable Aralia Systems to develop 3D imaging technology for moving objects at very long range (100s metres) outside in daylight. This is currently not possible. The team has previously demonstrated how by controlling a network of existing near-IR illuminators and cameras, photometric stereo (PS), a shape from shading technique, can be used to capture high-resolution moving 3D images in an indoor environment. The project is timely as it will explore the feasibility of exploiting an exciting recent development in camera sensor technology, known as black silicon. Black silicon imaging allows the capture of artificially illuminated images in a depressed region of the solar spectrum (at 940nm) by using controlled LEDs and eye-safe lasers. This allows the use of PS to create information rich 3D hotspots that can be placed anywhere within a monitored environment. This development could allow a step change in the use of moving 3D imaging outdoors. This will enable Aralia to develop enhanced visualisation and threat detection software in surveillance applications.
