Patent number: 11662727Abstract: A wide-area motion imaging system provides 360° persistent surveillance with a camera array that is small, light-weight, and operates at low power. The camera array is mounted on a tethered drone, which can hover at heights of up to 400?, and includes small imagers fitted with lenses of different fixed focal lengths. The tether provides power, communication, and a data link from the camera array to a ground processing server that receives, processes and stores the imagery. The server also collects absolute and relative position data from a global positioning system (GPS) receiver and an inertial measurement unit (IMU) carried by the drone. The server uses this position data to correct the rolling shutter effect and to stabilize and georectify the final images, which can be stitched together and shown to a user live or in playback via a separate user interface.Type: GrantFiled: August 7, 2020Date of Patent: May 30, 2023Assignee: Massachusetts Institute of TechnologyInventors: Cindy Y. Fang, William D. Ross, Lauren L. White, Joseph Bari, William Cason, Donald Johnson, Christopher Bowen, Kyle Bojanowski, Victoria Dye

Patent number: 10638064Abstract: In time-delay-and-integrate (TDI) imaging, a charge-couple device (CCD) integrates and transfers charge across its columns. Unfortunately, the limited well depth of the CCD limits the dynamic range of the resulting image. Fortunately, TDI imaging can be implemented with a digital focal plane array (DFPA) that includes a detector, analog-to-digital converter (ADC), and counter in each pixel and transfer circuitry connected adjacent pixels. During each integration period in the TDI scan, each detector in the DFPA generates a photocurrent that the corresponding ADC turns into digital pulses, which the corresponding counter counts. Between integration periods, the DFPA transfers the counts from one column to the next, just like in a TDI CCD. The DFPA also non-destructively transfers some or all of the counts to a separate memory. A processor uses these counts to estimate photon flux and correct any rollovers caused by “saturation” of the counters.Type: GrantFiled: October 16, 2019Date of Patent: April 28, 2020Assignee: Massachusetts Institute of TechnologyInventors: Curtis Colonero, Michael W. Kelly, Megan H. Blackwell, Lauren L. White

Publication number: 20190238800Abstract: Security guards at large facilities, such as airports, monitor multiple screens that display images from individual surveillance cameras dispersed throughout the facility. If a guard zooms with a particular camera, he may lose image resolution, along with perspective on the surrounding area. Embodiments of the inventive Imaging System for Immersive Surveillance (ISIS) solve these problems by combining multiple cameras in one device. When properly mounted, example ISIS systems offer up to 360-degree, 240-megapixel views on a single screen. (Other fields of view and resolutions are also possible.) Image-stitching software merges multiple video feeds into one scene. The system also allows operators to tag and follow targets, and can monitor restricted areas and sound an alert when intruders breach them.Type: ApplicationFiled: April 10, 2019Publication date: August 1, 2019Inventors: Daniel B. Chuang, Lawrence M. Candell, William D. Ross, Mark E. Beattie, Cindy Y. Fang, Bobby Ren, Jonathan P. Blanchard, Gary M. Long, JR., Lauren L. White, Svetlana V. Panasyuk, Mark Bury
