  • Patent number: 9767365
    Abstract: The present invention relates to a system and a method of monitoring a queue that allow for exactly recognizing objects in a queue and exactly monitoring the situation of the queue by tracking the recognized objects, using depth detection device such as a TOF camera. According to the present invention, it is possible to map a space and an image using depth information provided through a depth detection device without mapping a 3D space to an image taken by a camera and exactly measure the actual heights of objects from the ground using depth information of the objects and the background and initial parameters of the depth detection device so that desired objects can be exactly detected and recognized in filtering. Accordingly, the system can be less complicated. Further, waiting time is assigned to recognized objects so that they can be easily tracked.
