摘要： Techniques are disclosed for systems and methods to provide graphical user interfaces for assisted and/or autonomous navigation for mobile structures. A navigation assist system includes a user interface with a display for a mobile structure and a logic device configured to render a docking user interface on the display. The logic device determines a direction and magnitude of a navigational bias associated with navigation of the mobile structure and determines a spatially biased safety perimeter and hazard monitoring area within a monitoring perimeter of a perimeter ranging system mounted to the mobile structure, based on the direction and magnitude of the navigational bias. The docking user interface includes a maneuvering guide with a virtual bumper perimeter intrusion indicator configured to indicate a relative position and/or proximity of a navigation hazard within the spatially biased hazard monitoring area.

摘要： Systems and methods include an image capture component configured to capture infrared images of a scene, and a logic device configured to identify a target in the images, acquire temperature data associated with the target based on the images, evaluate the temperature data and determine a corresponding temperature classification, and process the identified target in accordance with the temperature classification. The logic device identifies a person and tracks the person across a subset of the images, identify a measurement location for the target in a subset of the images based on target feature points identified by a neural network, and measure a temperature of the location using corresponding values from one or more captured thermal images. The logic device is further configured calculate a core body temperature of the target using the temperature data to determine whether the target has a fever and calibrate using one or more black bodies.

摘要： Various techniques are provided to perform flat field correction (FFC) for infrared cameras. In one example, a system includes a focal plane array (FPA) of an infrared camera configured to capture thermal image data in response to infrared radiation received by the FPA via an optical path of the infrared camera. The system further includes a memory configured to store a set of supplemental FFC values. The system further includes a processor configured to determine a scale factor based at least on a temperature and/or a rate of temperature change of an internal component of the infrared camera; generate a scaled set of supplemental FFC values based on the scale factor and set of supplemental FFC values; and apply the scaled set of supplemental FFC values to the thermal image data to adjust for non-uniformities associated with at least a portion of the first optical path.

摘要： Various techniques are disclosed for separating and removing low-frequency shadow or shading (also referred to herein as "non-uniformity") from images that have been corrupted by the non-uniformity. A non-uniformity estimate that approximates the non-uniformity effect on the corrupted image may be generated by iteratively adding new blotches of non-uniformity data represented by two-dimensional (2D) functions, such as 2D Gaussian functions, to the non-uniformity estimate and applying filters to smoothen the 2D functions. In each iteration of the non-uniformity estimate generation process, a new non-uniformity update candidate that minimizes a cost function is identified. The corrupted image is processed based on the non-uniformity estimate to generate a corrected image.

摘要： Various techniques are provided for reducing noise in captured image frames. In one example, a method includes determining row values for image frames comprising scene information and noise information. The method also includes performing first spectral transforms in a first domain on corresponding subsets of the row values to determine first spectral coefficients. The method also includes performing second spectral transforms in a second domain on corresponding subsets of the first spectral coefficients to determine second spectral coefficients. The method also includes selectively adjusting the second spectral coefficients. The method also includes determining row correction terms based on the adjusted second spectral coefficients to reduce the noise information of the image frames. Additional methods and systems are also provided.
