System and method for recording animals

A method for recording animals with a system with a 3-D camera unit which is designed for producing at least one three-dimensional image of an animal, a computer unit which is designed for determining a weight of the animal based on the at least one three-dimensional image and a data memory, in which weight data can be saved for each animal, wherein the 3-D camera unit, an auxiliary means and/or the computer unit is designed for identifying an animal from a group of animals, wherein an output means is provided to output animal-related data, wherein the output means comprises a visual element, by which supporting data, which are saved for the animal or generated in the computer unit, can be displayed on observation of the animal, the method comprising:

• in an initial phase, weighing at least individual animals and inputting the weight thus ascertained into the computer unit,
• producing by means of the 3-D camera unit the at least one three-dimensional image of the animal,
• determining, based on the at least one three-dimensional image, the weight of the animal by means of the computer unit,
• comparing, by the computer unit, the weight ascertained by weighing with the weight data determined by calculation,
• in the case of a deviation, the computer unit changing a stored algorithm for determining the weight data based on the recorded image so that the weight data determined by calculation approximate or correspond to the weight ascertained by weighing,
• storing parameter data, the parameter data comprising average data for a weight development over time,
• comparing, by the computer unit, the weight data at a point in time to the average data for the weight development over time and outputting a handling instruction to administer a veterinary measure for a disease of the animal in response to determining that the weight data at the point in time deviates from the average data for the weight development,
• saving the recorded weight data for each animal in the data memory configured as a decentralized blockchain,
• managing, by the computer unit, access to the recorded weight data via a self-governed rights management system based on certificates that enable a transfer of data access rights without a central administration authority, and
• executing a smart contract to facilitate a transfer of the animal on an electronic marketplace based on the recorded weight data and the certificates.
