Patent number: 9621823Abstract: A system for calibrating a thermal camera with a calibration target. The calibration target may have a pattern which can be seen on an infrared image captured by the camera. The pattern may be of various kinds. For example, the pattern may be a checkerboard with some, such as every other square, having one emissitivity and the remaining squares having a different emissitivity, or having infrared light sources placed at corners of the squares. A difference between the emmissitivities may be sufficient so that the checkerboard pattern appears in an infrared image captured by the camera for calibration. The calibration may aid in determining intrinsic and extrinsic parameters of the camera. The parameters may provide a basis for transforming camera pixel coordinates to a world coordinate system which allows measurement of real world entities by the thermal camera. Measurements may incorporate distances between objects, heights of objects, and so forth.Type: GrantFiled: September 16, 2010Date of Patent: April 11, 2017Assignee: Honeywell International Inc.Inventors: Dinesh Ramegowda, Mohammed Ibrahim Mohideen, Lokesh Rayasandra Boregowda, Bin Sai, Vijendran Gopalan Venkoparao

Publication number: 20120281096Abstract: A multi-sensor method and system for imaging and inspecting a storage tank that holds a liquid. The system includes an infrared sensor including a scanning vertical mount positioned outside the storage tank, an ultrasonic sensor array positioned outside the storage tank, and at least one of an ultrasonic sensor positioned inside the storage tank and a phased array radar positioned inside the storage tank secured to an interior top surface of the storage tank. The system further includes a processor coupled to receive multi-sensor data from the infrared sensor, ultrasonic sensor array and at least one of the ultrasonic sensor in the tank and the phased array radar. The processor fuses the multi-sensor data to generate a sludge level image profile for sludge in the storage tank, a liquid level image for liquid in the storage tank, and optionally an integrity profile for a shell of the storage tank.Type: ApplicationFiled: May 2, 2011Publication date: November 8, 2012Applicant: HONEYWELL-ENRAF B.V.Inventors: Mahesh Kumar Gellaboina, Lokesh Rayasandra Boregowda, Mohammed Ibrahim Mohideen, Dinesh Ramegowda, Bin Sai

Patent number: 8284997Abstract: A system and method of determining aircraft position on an aerodrome ground surface having a centerline disposed thereon is provided. A current image of the aerodrome ground surface is captured using a camera that has a known focal length and is disposed on a vehicle at a preset pitch angle. The current image includes the centerline, which extends to a vanishing point in the captured image. The slope and intercept of at least a portion of the centerline are computed. The vertical and horizontal positions of the vanishing point are computed. An estimate of the vehicle position on the ground surface is computed using the computed horizontal and vertical positions of the vanishing point, the known focal length, and the preset pitch angle.Type: GrantFiled: March 11, 2009Date of Patent: October 9, 2012Assignee: Honeywell International Inc.Inventors: Mohammed Ibrahim, Dinesh Ramegowda, Peter J.

Patent number: 8040258Abstract: Methods and apparatus are provided for enhancing the situational awareness of an operator. Automatic dependent surveillance-broadcast (ADS-B) traffic data transmitted by a traffic entity are received. The ADS-B traffic data are processed to determine traffic entity position. The traffic entity position is mapped to corresponding image coordinates on an enhanced vision system (EVS) display. A region of interest around at least a portion of the corresponding image coordinates is selected. An actual image of the traffic entity is rendered on the EVS display, at the corresponding image coordinates, and with at least a portion of the region of interest being highlighted.Type: GrantFiled: April 7, 2009Date of Patent: October 18, 2011Assignee: Honeywell International Inc.Inventors: Mohammed Ibrahim, Dinesh Ramegowda

Patent number: 7826666Abstract: Systems and methods for determining whether a region of interest (ROI) includes a runway are provided. One system includes a camera for capturing an image of the ROI, an analysis module for generating a binary large object (BLOB) of at least a portion of the ROI, and a synthetic vision system including a template of the runway. The system further includes a segmentation module for determining if the ROI includes the runway based on a comparison of the template and the BLOB. One method includes the steps of identifying a position for each corner on the BLOB and forming a polygon on the BLOB based on the position of each corner. The method further includes the step of determining that the BLOB represents the runway based on a comparison of the polygon and a template of the runway. Also provided are computer-readable mediums storing instructions for performing the above method.Type: GrantFiled: December 17, 2008Date of Patent: November 2, 2010Assignee: Honeywell International Inc.Inventors: Rida M. Hamza, Mohammed Ibrahim Mohideen, Dinesh Ramegowda, Thea L. Feyereisen
