System for detecting degradation of paint autonomously applied to a building

A method for detecting degradation of paint comprising:

• during a first time period:
• segmenting a first structure into a constellation of painted areas;
• for each painted area in the constellation of painted areas:
• accessing a set of paint attributes of the painted area and comprising:
• a pre-paint surface quality of the painted area prior to paint application onto the painted area;
• an environment exposure condition of the painted area following paint application onto the painted area;
• and
• a set of ambient conditions, proximal the painted area, during application of paint onto the painted area;
• and
• accessing a paint failure status of the painted area, the paint failure status representing:
• one of presence and absence of a detected paint failure in the painted area;
• and
• responsive to presence of the detected paint failure in the painted area, an elapsed duration from paint application onto the painted area to occurrence of the detected paint failure in the painted area;
• and
• generating a paint failure prediction model representing relationships between sets of paint attributes and paint failure statuses of the constellation of painted areas on the first structure;
• and
• during a second time period:
• segmenting a second structure into a constellation of target areas;
• accessing a target paint efficacy duration for the second structure;
• for each target area in the constellation of target areas:
• retrieving a surface quality of the target area;
• generating a predicted environment exposure condition of the target area, following paint application onto the target area, for the target paint efficacy duration;
• and
• based on the paint failure prediction model, the surface quality of the target area, and the predicted environment exposure condition of the target area, calculating a set of ambient condition ranges corresponding to likelihood of paint failure in the target area prior to the target paint efficacy duration;
• and
• compiling sets of ambient condition ranges for the constellation of target areas into a paint specification for the second structure.
