Summary:The present invention is used in a ground surface recognition step for object augmentation in an augmented-reality service device, and provides an augmented-reality service device and method enabling guidance to be provided so that a user can easily and promptly identify whether an object to be augmented is a proper distance from the user during ground surface recognition. An augmentation-reality service device for providing a proper distance display of the present invention comprises: a camera for recognizing a ground surface and collecting data of the recognized ground surface; a ray casting unit for performing ray casting from the camera to the ground surface; and an image analysis unit for checking a conflict point with the ground surface data collected according to the ray casting, and measuring the distance between the conflict point and the camera to perform region classification according to the distance. La présente invention est utilisée dans une étape de reconnaissance de surface du sol pour une augmentation d'objet, dans un dispositif de service de réalité augmentée, et fournit un dispositif et un procédé de service de réalité augmentée permettant de fournir un guidage de telle sorte qu'un utilisateur puisse facilement et rapidement identifier si un objet à augmenter se situe à une distance appropriée de l'utilisateur pendant la reconnaissance d'une surface de sol. Selon la présente invention, un dispositif de service de réalité augmentée, destiné à fournir un affichage d'une distance appropriée, comprend : une caméra destinée à reconnaître une surface de sol et collecter des données de la surface de sol reconnue ; une unité de lancer de rayons destinée à effectuer un lancer de rayons, de la caméra à la surface de sol ; et une unité d'analyse d'image destinée à vérifier un point de divergence avec les données de surface de sol collectées conformément au lancer de rayons et à mesurer la distance entre le point de divergence et la caméra pour effectuer une classification de région en fonction de la distance. 본 발명은 증강현실 서비스 장치에서의 오브젝트(object)의 증강을 위한 지면 인식 단계에서 사용되는 것으로서, 지면 인식 시 사용자가 증강하고자 하는 오브젝트가 사용자로부터 적정 거리에 있는지를 쉽고 빠르게 파악할 수 있도록 가이드해 줄 수 있는 증강현실 서비스 장치 및 방법을 제공한다. 본 발명의 적정 거리 표시를 제공하는 증강현실 서비스 장치는, 지면을 인식하고 인식한 지면 데이터를 수집하는 카메라, 상기 카메라로부터 상기 지면으로 레이캐스팅(Raycasting)을 수행하는 레이캐스팅부, 및 상기 레이캐스팅에 따른 수집한 지면 데이터와의 충돌 지점을 체크하고, 상기 충돌 지점과 상기 카메라 간의 거리를 측정하여 상기 거리에 따른 영역분류를 수행하는 영상 분석부를 포함한다.
