Abstract: A system for determining a location of a feature of an object, the system including a first marker including a first area and a surface having two parallel edges and a third edge disposed perpendicularly to the two parallel edges, the two parallel edges are disposed about a first central axis of the two parallel edges; and a sensor configured to provide a distance from the sensor to a portion of the first marker, wherein the sensor is adapted to obtain distances between the sensor and the first marker and an environment surrounding the first marker to form a first map representing the distances corresponding to locations from which the distances are obtained using the sensor and the location of the feature of the object is determined based on at least one corner corresponding to an intersection formed of the third edge and one of the two parallel edges.

Abstract: A welfare-oriented raising house for meat-type ducks, including a raising house, is provided. The raising house is internally provided with a support frame which is of a U-shaped structure and arranged in a length direction of the raising house, a raising net arranged at a top of the support frame, a cleaning and storing mechanism arranged at one end of the support frame for cleaning and storing the raising net, a traction mechanism arranged at the other end of the support frame for the traction of the raising net, blocking mechanisms which are of a zigzag structure and arranged at both sides of the support frame, and tensioning vibration mechanisms arranged at bottoms of the blocking mechanisms and fixedly connected to a side edge of the support frame.
