Patent number: 10366509Abstract: Creating a background model for image processing to identify new foreground objects in successive video frames. A method includes providing a background image in a user interface. The method further includes receiving a first user input in the user interface that comprises an identification of one or more different regions within the background image. The method further includes receiving a second user input in the user interface that comprises a selection of an image change tolerance for each of the identified different regions. The method further includes providing the background image, information identifying the different regions, and the image change tolerances to an image processor. The background image, the information identifying the different regions, and the image change tolerances are used by the image processor to create a background model to thereby compare a successive image with the background model in order to identify foreground objects within the successive image.Type: GrantFiled: March 29, 2016Date of Patent: July 30, 2019Assignee: Thermal Imaging Radar, LLCInventors: Lawrence Richard Jones, Bryce Hayden Lembke, Sezai Sablak, Michael D.

Patent number: 10127686Abstract: A seamless lens cover, and methods of forming such a seamless lens cover. The cap structure that covers a camera of a rotating panoramic camera system includes a seamless lens cover through which images are obtained by the camera. The cap structure may be injection molded at an initial lens cover thickness, and then a portion of the as molded initial lens cover thickness may be removed (e.g., by machining away) to achieve the final desired thickness. By such a method, the lens cover may be injection molded at thicknesses suitable for injection molding (e.g., about 0.06 to about 0.1 inch), after which most of the thickness may be machined away, to provide a seamless lens cover having a thickness of less than about 0.015 inch, exhibiting at least 60% transmittance to the thermal spectrum, no lensing characteristics, and no curvature effect.Type: GrantFiled: May 19, 2016Date of Patent: November 13, 2018Assignee: THERMAL IMAGING RADAR, INC.Inventor: Michael D.

Patent number: 9886776Abstract: Thermal imaging camera images are obtained from a thermal imaging camera that rotates through a plurality of stop positions. The camera captures images at a constant frame rate and at least some of the images correspond to stop positions. Thermal imaging camera images that correspond to a stop position are retained, while images that do not correspond to a stop position are discarded. Retained images are sent in a video stream to a video processor. The video stream is separated into individual thermal imaging camera images and stored for corresponding virtual camera devices that correspond to specific stop positions. In addition, the position of the camera and individual pixels of images are both correlated to geographical location data, and depth values for the pixels are determined based on the geographical data.Type: GrantFiled: December 5, 2016Date of Patent: February 6, 2018Assignee: Thermal Imaging Radar, LLCInventors: Michael D. Dortch, Larry J. Price

Patent number: 9685896Abstract: Controlling a stepper motor. A stepper motor is driven towards an index position. An attempt is made to stop the stepper motor on the index position in a fashion that would ordinarily cause the stepper motor to ring at the index position. Characteristics of one or more subsequent pulses that would counteract the ringing are determined. The one or more determined subsequent pulses are issued to the stepper motor.Type: GrantFiled: April 9, 2014Date of Patent: June 20, 2017Assignee: Thermal Imaging Radar, LLCInventors: Michael D. Dortch, Larry J. Price, Brian A. Wittman, Shaun P. Greene

Patent number: 9390604Abstract: Detecting an extreme temperature event. A method includes collecting raw data from a high resolution sensor. The method further includes identifying in the raw collected data one or more changing data point values. The method further includes identifying, in the raw collected data that the one or more changing data point values have reached a determined threshold that indicates with a high level of probability that an extreme temperature event has occurred. Alternatively, the method may include identifying in the raw collected data a sudden extreme increase in one or more data point values that cross a threshold which indicates with a high level of probability that an extreme temperature event has occurred. As a result, the method includes issuing an alert indicating that an extreme temperature event has occurred.Type: GrantFiled: April 9, 2014Date of Patent: July 12, 2016Assignee: THERMAL IMAGING RADAR, LLCInventors: Michael D.

Patent number: 8773503Abstract: An indexing mechanism may include a drive table, an indexing table, a control ring between the tables, and a cam follower. The cam includes lobes on an inner surface. A drive arm of the cam follower is coupled to the drive table and an end of an indexing arm of the cam follower rides over the lobes during use. A spring may be coupled between the drive table and the indexing table. As the drive table rotates continuously, the components serve to move the indexing table in a non-continuous movement, by which it stops for a period and then moves to the next stop, etc. A camera may take a still image at each stop position, and the images may be stitched together (e.g., through use of an onboard computer) to produce a panoramic image. A power supply may also be provided, so that the entire system may be self-contained.Type: GrantFiled: January 18, 2013Date of Patent: July 8, 2014Assignee: Thermal Imaging Radar, LLCInventors: Michael D.
