A Low-cost autonomous tracking camera system for 3d marker-less motion capture of animals in the wild
… (red green blue) or RGB-D (red green blue-depth) cameras. Physical constraints limit the amount of data that can be collected with a single sensor (or set of sensors) since the subject is typically constrained to a specific capture area based on the sensor's field of view (FOV). This study focuses …
