- the method 1 100 may include a step of applying 1 101 an order, a step of executing 1 103 an order and a step of storing 1 105.
- an order for the automated recording of documents to be detected features can be defined.
- the application 1 101 of an order for example, using a computer and a reader, for example, for identification documents, are performed.
- Execution 1 103 of the order can be carried out, for example, by means of the image acquisition system 100.
- the capturing features, image captures and / or image capture series are stored, for example, in a database or a server.
- the method 1 100 can be coordinated by a work order or contract.
- the detection of a document and the filing for example, the features to be recorded, the image recordings and / or the image acquisition series, can be controlled in the database.
- This process can be done partially automated for machine-readable documents, for example.
- existing work orders for example, can be used as templates or templates.
- standardized image recording cameras or cameras as well as lighting profiles can be used for data acquisition.
