Another way to quantify the detected and measured cracks is to determine their orientation. Orientation is a desirable characteristic because of the way certain vessels are constructed. Depending on the construction characteristics of a given vessel, cracks are most likely to occur along brick lines. Knowing the main orientation that, for example, the refractory material may have been disposed, one may search and characterize cracks that are substantially aligned with that main orientation depending on a particular application. Those of ordinary skill in the applicable arts will appreciate that the apparatuses, systems, methods, and processes being disclosed are general. As such, one is capable to search for a certain direction or facets grouped together along such a direction. In addition, experienced gain in working with certain types of vessels and their refractory materials, best programmable orientation may be decided by experience, type of application, how bricks were laid, orientation selected as function of type of brick, and/or expected type of crack in a given application, to name just a few examples.
