ENHANCED VISUAL REPRESENTATION OF INFRARED DATA VALUES

摘要

Various techniques are provided to generate enhanced visual representations of captured infrared (IR) data values. For example, various methods, systems, devices, and machine-readable mediums are provided that may be used to map color and/or grayscale values to temperature values. Such mapping permits a user to intuitively interpret the temperatures associated with the IR data values. The temperatures may be presented as a visual representation of the captured IR data values having an enhanced contrast.

1. A method comprising:
receiving a frame of infrared (IR) data values captured by a detector comprising a plurality of detector elements, wherein the frame comprises, for each detector element, a pixel having an assigned one of the IR data values representing a temperature value associated with infrared radiation emitted from an observed real world scene and received by the detector element; and generating a visual representation of at least a portion of the IR data values assigned to a corresponding set of the pixels, wherein the visual representation comprises, for each pixel, at least one color-representing component and a grayscale component according to a color model, and wherein the generating the visual representation comprises:
assigning, for each pixel, a value to the at least one color-representing component based on the IR data value of the pixel and according to a first mapping between IR data values representing temperatures and color-representing component values from a palette, the first mapping being invariable with respect to the range of the captured IR data values in the frame so as to maintain a fixed temperature-to-color mapping, andassigning, for each pixel, a value to the grayscale-representing component based on the IR data value of the pixel and according to a second mapping between IR data values and grayscale-representing component values from the palette, the second mapping being independent of the first mapping.
