Abstract

In this paper, Kinect based sensors are used to enable automatic animal detection for monitoring and assessment the growth of livestock. Benefitted from the fast developing 3-D machine vision devices and techniques, it is liable to detect the object using the point cloud data. In the present work, a Kinect sensor is installed on the roof of the pig pen to obtain the 3-D data. After thresholding the depth of each pixel, a depth image is generated where the objects within the depth range are extracted. Several shape based constraints are then applied to refine the detected object regions for accurate estimation of the size and weights for further process. Experimental results have validated the efficacy of the proposed approach.
