The façade of the building is generally inspected thoroughly and methodically by visually scanning the exterior both horizontally and vertically with tripod mounted binoculars, and deficiencies documented with the aid of a camera with a telephoto lens. The condition of the roofing and parapets are also observed, as they could be sources of moisture within the façade. The purpose of the general inspection is to identify anomalies that require close-up detailed inspection.
Thanks to the development of Drone technology, there is now an intermediate step between general and detailed close-up inspection. Anomalies identified during the general inspection in difficult to reach parts of the façade, can sometimes be eliminated from close-up inspection with the use of close-up video inspection utilizing Drone Harmony 3-D technology employed by AYRTIME.
The Drone facade Inspection is ideal for capturing detailed imagery data of facades, photogrammetry and detailed close-up inspections of walls that have high 3-D detail (balconies, sculptures etc.). The difference between Façade Inspection and Façade Verticals/Horizontals is:
- Façade Inspection aircraft fly curved verticals that bend over the roof of the inspected structure. The higher images are useful for inspecting the parts of the wall that connect of the roof of the structure. These images are also essential if photogrammetric model of the façade that includes part of the roof is to be constructed.
- In every vertical of the Façade Inspection mission, images are included with two different camera angles, both of which are not facing the wall directly. This allows the aircraft to capture more of the 3-D detail on the wall and account for possible occlusions.
- Reduction in field time for inspection and increase safety
- Reduction in field costs
- Limit exposure to field personnel
- Provide access to difficult locations
- Capture videos and pictures of problem areas
