Patent number: 10367996Abstract: Example apparatus and methods produce image correction data for a lens or sensor based on individual images acquired under different operating parameters. Example apparatus and methods then produce strip correction data based on a strip of images pieced together from the individual images. Example apparatus and methods then produce panoramic image correction data based on a panoramic image pieced together from two or more strips of images. The strip of images is produced without using a hemispherical mirror and thus accounts more accurately for issues associated with making a two dimensional representation of a three dimensional spherical volume. Images are acquired using different imaging parameters (e.g., focal length, pan position, tilt position) under different imaging conditions (e.g., temperature, humidity, atmospheric pressure, pan rate, tilt rate) to account for aberrations that may appear or be exacerbated under operating conditions.Type: GrantFiled: December 5, 2017Date of Patent: July 30, 2019Assignee: IEC Infrared Systems, LLCInventors: Richard Pettegrew, John Paximadis

Patent number: 10084960Abstract: Example apparatus and methods acquire individual frames of a portion of a scene under a variety of different operating parameters. Example apparatus and methods then piece together strips of frames from the individual frames. Example apparatus and methods then produce a panoramic image from the strips of frames. Frames are acquired using different imaging parameters (e.g., focal length, pan position, tilt position) under different imaging conditions (e.g., temperature, humidity, atmospheric pressure, pan rate, tilt rate). The frames may be acquired by cameras located in a panoramic view image system and in a drone. The drone may provide imagery or data. The imagery or data may be used to update or enhance the panoramic image by, for example, displaying imagery of a blind spot in the panoramic image. In different embodiments, drones may be detected or controlled.Type: GrantFiled: September 25, 2015Date of Patent: September 25, 2018Assignee: IEC Infrared Systems, LLCInventors: Richard Pettegrew, John Paximadis

Patent number: 9420177Abstract: Example systems and methods acquire individual frames under a variety of different operating parameters. Example systems and methods then piece together strips of frames from the individual frames. Example systems and methods then produce a panoramic image from the strips of frames. Frames are acquired using different imaging parameters (e.g., focal length, pan position, tilt position) under different imaging conditions (e.g., temperature, humidity, atmospheric pressure, pan rate, tilt rate). Range information is acquired and associated with different locations (e.g., pixels) in frames. Range information may be acquired for some locations and estimated for other locations. Blind spots in a scene may be identified. Range information may then be retrieved quickly from the panoramic image or from a data structure associated with the panoramic image without having to find the range again.Type: GrantFiled: September 25, 2015Date of Patent: August 16, 2016Assignee: IEC Infrared Systems LLCInventors: Richard Pettegrew, John Paximadis

Patent number: 7573033Abstract: Systems, methods, and other embodiments associated with automatically optimizing cyclic integration are described. One method embodiment includes repetitively acquiring a thermal intensity data using an infrared detector configured to operate for an integration time. The method embodiment may also include extracting a useable data from the intensity data and then updating a rolling composite image with the useable data. The method may also include selectively automatically updating the integration time based on whether the thermal intensity data included a value that fell outside the pre-determined range.Type: GrantFiled: February 23, 2007Date of Patent: August 11, 2009Assignee: Innovative Engineering & Consulting Corp.Inventors: John M.

Patent number: 6900729Abstract: A system for processing thermal signature data is provided. The system provides a thermal signature data processor that analyzes one or more pixels to determine whether an aspect of an alarm-worthy event has occurred. In one example, the system additionally analyzes visual data in relation to the thermal signature data to determine whether an alarm-worthy event (e.g., intrusion) has occurred.Type: GrantFiled: March 17, 2003Date of Patent: May 31, 2005Inventors: John Matthew Paximadis, Richard Pettegrew

Publication number: 20040223062Abstract: A pan and tilt camera system is provided. The system involves positioning a payload (e.g., camera, sensor, controlling electronics) with its center of mass substantially centered over both the pan and tilt axes, which facilitates increasing the payload of a pan and tilt system by reducing and making more constant the load on panning and/or tilting motors. With the more constant motor loads, smoother and finer camera and/or sensor control is possible than with conventional systems. Example systems also provide for belt drive motors, a survivable casing, and a casing adapted for a larger variety of lens sizes.Type: ApplicationFiled: May 5, 2003Publication date: November 11, 2004Inventors: Richard Pettegrew, Michael Dobbs, Eric Anderson, William Yanis, John Matthew Paximadis, Richard Stepnowski, Paul Ferkul
