Abstract: Methods and apparatus for monitoring a temperature of an object over time using a thermal imaging camera. The methods and apparatus may gather infrared temperature data from a selected source of temperature data within a scene at a selected time interval and display a graphical plot of the gathered temperature data on a digital display.

Abstract: The invention relates generally to edge detection and presentation in thermal images. Infrared and visible light images comprising at least partially overlapping target scenes are analyzed. An edge detection process is performed on the visible light image to determine which pixels represent edges in the target scene. A display image is generated in which some pixels include infrared image data and in which pixels corresponding to edges in the visible light image include a predetermined color and do not include corresponding infrared image data to emphasize edges. Edge pixels in the display image can include exclusively the predetermined color, or in some examples, a blend of a predetermined color and visible light image data. Methods can include replacing one or the other of visible light edge pixels or corresponding infrared pixels with the predetermined color before combining the visible light and infrared image data to create a display image.

Abstract: A graphical user interface for configuring parameters associated with a portable infrared imager is provided. The interface can be used to manually or automatically set range and span parameters. The interface can also be used to configure one or more alarms to notify a user that a detected temperature is outside a predetermined range.

Abstract: A thermal imaging camera that intermittently captures thermal images of a scene for long term monitoring of the scene. The thermal images may be captured after each interval of a time delay interval and/or upon detection of a threshold change in thermal energy in the scene.

Abstract: A method and computer program product for determining whether an object of interest can have its temperature measurement calculated by a thermal imaging camera. To do this, the measurement IFOV is converted into linear units. The measurement IFOV may be displayed on the display of the camera as a graphical indicator (100, 100?, 100?, 100??) or a value. An object of interest can be registered with the graphical indicator (100, 100?, 100?, 100??) or its dimension compared with the measurement IFOV and then it is determined whether the temperature measurement of the object can be acceptably calculated. Alternately, data obtained by a matrix of pixel elements may be analyzed to determine whether an accurate temperature can be calculated.

Abstract: An interactive graphical user interface includes a moveable pointer, which may be activated to select points of a computer-generated thermal image of an object, as the pointer is moved over a display of the image, so that line temperature profiles, which correspond to predetermined lines extending through the selected points, may be viewed, for example, on a line temperature profile chart of the interface, for each selected point as the pointer is moved. Each predetermined line extends between the corresponding selected point and another, predetermined, point of the image. The other predetermined point may either coincide with an origin of an x-axis or a y-axis of an orthogonal coordinate system, in which the image is aligned, or may be any other point of the thermal image, for example, one that is pre-selected by a user, with the moveable pointer.

The interface can be used to manually or automatically set range and span parameters. The interface can also be used to configure one or more alarms to notify a user that a detected temperature is outside a predetermined range. In some embodiments, a non-linear temperature scale can be displayed.

Abstract: A thermal imaging system to facilitate analysis of thermal images comprises a portable thermal imager having a communication interface for transfer of data. The imager also has an on-board memory in which image data for corresponding thermal images is stored. A remote computer is operative to communicate with the thermal imager via the communication interface for download of the image data. The computer runs software operative to superimpose at least one marker at a selected location on a thermal image, the marker being saved on the image.

Abstract: A thermal imaging camera may be used to capture a visible-light (VL) image and an infrared (IR) image. In some examples, the camera includes adjustable focus IR optics. For example, the camera may include a focus mechanism coupled to the IR optics and configured to move the IR optics to various focus positions so as to focus the IR optics. The various focus positions may include a hyperfocal position in which a scene is in focus between a set distance and infinity, and a plurality of focus positions in which the scene is in focus between the set distance and a minimum focus distance. Depending on the configuration of the camera, the IR optics of the camera may define an F-number greater than 1.0, and an axis of the IR optics may be offset from an axis of the VL optics by a distance less than 1.7 inches.

Abstract: A method and computer program product for determining whether an object of interest can have its temperature measurement calculated by a thermal imaging camera. To do this, the distance between the camera and the object of interest is measured, then a measurement IFOV is calculated using the measure distance. The measurement IFOV may be displayed on the screen of the camera as a graphical indicator of the object of interest can be registered with the graphical indicator and then it is determined whether the temperature measurement of the object can be acceptably calculated.
