Title:
ENVIRONMENT-BASED METHOD AND SYSTEM FOR COMBINING THREE-DIMENSIONAL SPATIAL RECOGNITION AND TWO-DIMENSIONAL COGNITIVE REGION SEGMENTATION FOR REAL-VIRTUAL MATCHING OBJECT ARRANGEMENT
Document Type and Number:
WIPO Patent Application WO/2021/137349
Kind Code:
A1
Abstract:
According to the present invention, a location and direction of a portable terminal are tracked by using simultaneous localization and mapping (SLAM) that is a spatial recognition technology using a camera and an inertial sensor, and three-dimensional spatial information of a real space is generated, wherein a spatial object is generated by using an image obtained from the camera and cognitive region segmentation, and is projected onto a three-dimensional space, so that a floor and a table can be distinguished from each other, which is a limitation of plane recognition in SLAM and is impossible in the prior art. Therefore, virtual content that allows a user to interact with an object in a real space according to a pre-planned scenario DB can be provided, thereby providing a high sense of presence and interaction.
