ANIMAL TAG, METHOD AND COMPUTER PROGRAM FOR DETERMINING BEHAVIOR-RELATED DATA

摘要

A three-dimensional accelerometer in an animal tag registers a first set of acceleration parameters expressing a respective acceleration of the tag along each of three independent spatial axes. A processor in the tag derives a respective estimated gravity-related component in each parameter in the first set, and compensates for the respective estimated gravity-related components in the first set to obtain a second set of acceleration parameters representing respective accelerations of the animal tag along each of three independent spatial axes each in which the parameter is balanced around a base level with no influence of gravitation. The processor determines behavior-related data of rise-up and/or lie-down movements of an animal carrying the animal tag based on deviations in a single parameter in the second set of acceleration parameters relative to the base level.
