Definitions
- the invention relates to an arrangement and a method for inspecting an object, in particular a building, according to the preambles of the independent claims.
- Structures require regular and detailed inspections by qualified inspection specialists to record a condition of the structure. This also applies to many other objects.
- the inspections can provide information as to whether e.g. the structural integrity of the object
- the verification takes place during the creation, during the use, a conversion and a possible dismantling of the buildings.
- the inspections of a building include a comprehensive survey of the structure in which Inspection-relevant situations such as defects and / or
- Situations refer to defects exemplarily.
- a person skilled in the inspection analyzes these defects in a further step and, on the basis of this, derives a diagnosis, e.g. a type of defect or a topology of the defect. Due to the diagnosis, e.g. decided on further inspection steps and / or measures for the removal of the defects. This entails the risk that defects and their possible effects on the structure are overlooked and / or misjudged by the inspection expert.
- the registration of the defects usually involves registering the defects on a diagram such as e.g. a blueprint of a building during the inspection by the inspection specialist.
- the registered defects are usually detected electronically, e.g. entered into a database or recorded in a CAD-based blueprint of the building or a model of the building created, for example, using a known 3D scanner. This approach has on the one hand
