Method and device for checking value documents and method and device for generating checking parameters for the checking method

A method for generating templates for checking value documents of a predefined value document type, in which method value documents of the predefined value document type have at least two predefined production elements, which optionally partially overlap,

• wherein digital training images of training value documents of the predefined value document type are used, each of which have pixels each as-signed pixel data;
• the method comprising the following steps:
• for each of the training images, determining position data sets having position coordinates in a coordinate space each describing the positions of the production elements on the value document at least relative to one an-other, and
• forming at least two position sub-regions of the coordinate space, each comprising at least one predefined number of position data sets, the position sub-regions containing no common position data sets,
• for each of the position sub-regions, determining a template using training images of the value documents whose position coordinates lie in the position sub-region, and storing the template and position sub-region data describing the position and extent of each position sub-region.

A device for generating templates for checking value documents of a predefined value document type;

• wherein value documents of the predefined value document type have at least two predefined production elements, which optionally partially overlap,
• wherein digital training images of training value documents of the predefined value document type are used, each of which have pixels each assigned pixel data, the device comprising a storage unit for storing digital training images of value documents of the predefined value document type,
• wherein the device is configured to carry out a method according to the invention according to claim using the training images,
• wherein the device has an interface via which the generated templates and position subregion data can be transmitted to another device, and the device is configured to transmit the generated templates and the position sub-region data to the other device, and/or
• wherein the device is configured to store the generated templates and the position subregion data in a storage unit and/or the storage unit.
