1. A system for automatically monitoring a ruminant animal, comprising:
a 3D camera system for obtaining a plurality of 3D images of at least a region of interest of the animal at consecutive points in time during at least a predetermined period of time,
a control device connected to the 3D camera system, the control device comprising
an image processing device for processing the obtained plurality of 3D images, and
an output device,
the control device being arranged to determine a health parameter frequency value of a health parameter based on the processed 3D images, and to output the health frequency parameter value to the output device,
wherein the image processing device is arranged to
determine the region of interest in the plurality of 3D images and
calculate for each 3D image a curvature value of the region of interest, and determine the calculated curvature as a function of time,
wherein the control device is arranged to determine:
points in time when local extreme values of the function of time occur, and
the health parameter frequency value by analyzing the points in time with respect to a predetermined criterion.
