  • Patent number: 10554952
    Abstract: A stereo type distance recognition apparatus and method are provided. The stereo type distance recognition apparatus may include a plurality of sensors to generate a plurality of infrared (IR) signals, a communication unit to insert a set first pattern into each of the plurality of generated IR signals and to transmit the IR signals to an object, and a processor to extract a second pattern from each of signals reflected from the object by the plurality of IR signals, to cancel an interference signal from each of the reflected signals based on a result of a comparison between the first pattern and the second pattern, and to compute a distance from the object based on signals from which the interference signal is cancelled.
    Type: Grant

  • Patent number: 9323967
    Abstract: There are provided a method and a system of pallet packing that generate information on an article to be loaded and a loading place of the article on a specific pallet by recognizing a 3D position on which articles are loaded on a pallet, and a method for providing loading information of the article on the pallet by using loading information of the article generated by the method. More particularly, there are provided a method and a system of pallet packing that generate information on a 3D loading position of each article by using identification information of the pallet and each article and depth information for a whole area of the pallet acquired through a depth measurement sensor and a method for providing information on a loading shape of all articles or a state in which a specific article is loaded by using loading information of the article generated through the method.
