This report defines the EPC Recast data acquisition technique as part of an EPC visit. So, this report connects image capture and processing technologies combined with semantic enrichment to fulfil an appropriate DM – Data Model in the context of EPC.
This deliverable provides a process for acquiring the DM using innovative 3D and AR (Augmented Reality) technology to capture volumes and plans and enrich the data with pictorial (photo) and structured (Technical) information at individual housing scales. The process of 3D scanning by drone is also introduced to provide geometric and thermographic information at the building scale. Two separate actions to be carried out as part of this task are identified:
- Provide a tool for capturing geometric data.
- Enrich the metric acquisition with additional information provided by the auditor during his visit. This information will enable it to qualify information from other generics (air quality, temperature level recorded …) or descriptive information (semantic information to objects, state, performance…).
There are two types of information captured by the BIMEO process:
- Geometric data: information captured by shape recognition integrated into the application. This data is built according to a geometric algorithm based on the definition of a part. The data will be delivered according to IFC formats (BIM format).
- Descriptive information: Information entered by the operator following his observation either directly or by a specific instrumentation. The data will be transmitted according to a CSV format to be built.
