SBIR Phase II: Range and Image Acquisition Using Active Control of CCD Plane

9529961哈特 这个小企业创新研究第二阶段项目将开发一种新的成像技术，称为非正面成像。这种新方法的核心是主动控制成像几何形状，以消除通常需要聚焦的传感器平面位置的机械调整，并利用成像几何形状和光学实现从相机的平移运动单独聚焦。这不仅导致高成像速度，而且在无缝全景图像。非正面成像相机可以获得任意大场景中所有对象的全景聚焦图像，而不管它们的位置，其与并行获取的范围图配准。提出了算法的开发和工作原型的构建，该工作原型将具有以下功能：全景聚焦图像采集，全景范围图像采集和全聚焦3D立体显示。所有这些功能都将以多种分辨率实现，并可实现高达360度的场景视图。传感器表面方向将以动态数据驱动模式进行控制。该原型将主要在涉及摄影和监视的应用中进行测试，并在较小程度上用于手术和制造。系统开发将与工业界协商进行。预计由此产生的技术将引入迄今为止尚不具备的能力，并导致现有能力的重大进步。该相机的美国专利已被授予，外国专利也已提交。 潜在的商业应用包括：宽场景摄影棚摄影;户外自然摄影;内窥镜和神经外科手术;电视广播;计算机辅助制造的几何建模;家庭，商店和化合物的监控;使用全方位聚焦3D显示的虚拟现实;广告;视觉艺术;危险环境的监测和控制;可视化;交互式视频游戏。

9529961 Hart This Small Business Innovation Research Phase II project will develop a new imaging technology called nonfrontal imaging. The core of this new approach is active control of imaging geometry to eliminate the mechanical adjustment of sensor plane location usually required for focusing, and exploit imaging geometry and optics to achieve focusing from camera's panning motion alone. This not only results in high imaging speeds but also in seamless panoramic images. A nonfrontal imaging camera can obtain a panoramic focused image of all objects in an arbitrarily large scene regardless of their locations, which is in registration with a range map acquired in parallel. Development of algorithms and the building of a working prototype are proposed which will have the following capabilities: panoramic focused image acquisition, panoramic range image acquisition, and omni-focused 3D stereo display. All these capabilities will be achieved at multiple resolutions and for up to 360-degree views of the scene. Sensor surface orientation will be controlled in a dynamic, data-driven mode. The prototype will be tested primarily in applications involving photography and surveillance, and to a lesser extent surgery and manufacturing. The system development will be done in consultation with industry. It is expected that the resulting technology will introduce hitherto unavailable capabilities as well as lead to significant strides in existing capabilities. A US patent on the camera has been awarded, and foreign patents have been filed. Potential commercial applications are: Wide-scene studio photography; Outdoor nature photography; Endoscopic and neurosurgery; Television broadcasting; Geometric modeling for computer aided manufacturing; Surveillance of homes, stores and compounds; Virtual reality using omni-focused 3D display; Advertising; Visual art; Monitoring and control of hazardous environments; Visualization; Interactive video games.
