What does SDTI mean in UNCLASSIFIED

SDTI stands for Spatial Displacement of Thermal Image. It is a technique used to measure the temperature of objects, primarily in industrial settings, that involves taking images from two different locations and combining them to create an accurate thermal image or map.

SDTI works by using two cameras with thermal sensors mounted at different angles. The cameras take images from the same scene but from different perspectives, which helps to create a more accurate temperature profile for the scene. These images are then combined together to form a thermal map.

SDTI is highly accurate and can be used for precise temperature measurement in a variety of industrial settings. The combination of multiple images from multiple angles yields highly detailed thermal maps that reveal even small changes in temperature.

SDTI can be used to detect hotspots in areas such as manufacturing plants, pipelines, data centers, electrical systems, and other critical infrastructure components. Additionally, it can also be used to monitor energy efficiency in buildings and find sources of heat loss or air infiltration.

In order to use the technique you will need two cameras with appropriate lenses and thermal sensors that are able to capture the required infrared signals for each location. You may also need external equipment such as computers for processing the data.

An SDTI map consists of several color bands which represent different temperatures ranges - the colder temperatures are represented by bluer colors while warmer temperatures are represented by redder colors. By studying these colors you can identify hot spots or cold spots on your map and draw conclusions based on this information.

There are no known risks associated with using the technique itself; however depending on what you are measuring there may be other safety considerations to keep in mind when analyzing your measurements or results (e.g., always wear proper personal protective equipment (PPE) if working near machinery).

The cost will depend on what hardware is needed for your specific application but typically the cost should fall within a reasonable range when compared to other techniques that could achieve similar results. Generally speaking, most people should find it feasible enough for their projects/applications.

SDTI has become increasingly popular among engineers and technicians for various industrial applications due its accuracy and flexibility in capturing data from different angles which gives more comprehensive results than traditional thermography methods alone could provide.

While setting up an image sequence does take careful planning ahead of time especially if changing angles between shots, it can get easier once familiarized with the process. Additionally many software solutions exist nowadays that make this task less cumbersome.
