Electromagnetic energy will behave in one or more of three ways when it is incident upon an object or encounters a medium boundary; it will either be absorbed, be reflected, or be transmitted.
Convection is the movement of a gas or fluid due to differences in density (gravity, natural convection) or physical force (mechanical convection).
In fact, thermography doesn’t even measure temperature!
Contrary to conventional wisdom, thermography does not measure temperature.
Digital imaging histograms (not to be confused with RGB Parades) are a census of pixels whose channel or composite values occupy certain “bins” or discrete values along the x-axis, or abcissa.
A common strategy for dealing with editing, rendering, and encoding output is to establish a “proxy” workflow; using less demanding “proxies” rather then original “resource hog” originals.
Photoshop is a shockingly “deep” application with latent but powerful features for generating selections.
Science is of peculiar value in jurisprudence but there is no particularly elegant fitment between the two philosophies.
The baseline and responsive documentation-and immediate dissemination-of technical (aerial, hyperspectral, etc.) imagery of flooding is tremendously practical.
Forensic LiDAR and “engineering grade” or “survey grade” LiDAR (LASER Scanning) are very different things. Applications in which engineering and survey LiDAR conventions are manifestly deficient include litigation and its ADR cousins (mediation, arbitration, etc.).
There is no excerpt because this is a protected post.
The images below represent some interesting results from both vertical (orthogonal) and oblique aerial thermography throughout 2018.
The EPA has established a Heat Island Reduction Program (HIRP) and expressed that it is useful for communities in the preparation of projects, programs, and policies. While this language is nurturing vice systemizing, the statement is contained in a section titled “What EPA is Doing to Reduce Heat Islands.” An intent is obvious, and it must be considered that EPA is not a hobbyist organization.
For the FLIR T10xx camera series lenses typically offer very low focal length ratios. The common 36mm/28°HFOV lens aperture is fixed at f1.15, while the less common 83.4mm/12°HFOV lens is fixed at f1.2.
It is a generally accepted principle to adjust the “exposure” of professional thermograms so that the bulk of the selected palette range is confined to features of interest in order to produce the finest representation of their thermal patterning.
