Abstract
An automated method for lameness detection can be an alternative for detection by regular
observations. Accelerometers attached to a leg of the dairy cow can be used to record the locomotion of a dairy cow. In an experiment the 3D acceleration of the right hind leg during walking of three dairy cows was measured and analysed. Nodes with a 3D accelerometer in a wireless sensor network were applied to measure with a frequency of 50 Hz. After data filtering, the data analysis was in two steps: first step detection and secondly the determination of step parameters. Variance analysis was used for step detection. For each step the parameters step length and step time were calculated. The steps and step parameters can be used in future research for gait analysis of lame and non-lame cows. The aim of this paper is to describe the collection and analysis of data in this experiment and to assess the possibilities for gait analysis. It can be concluded that the application
of accelerometers in a wireless sensor network gives promising results. Step detection is possible and step parameters can be derived.
