Title:
METHOD FOR GENERATING SPACE MAP IN ORDER TO SHARE THREE-DIMENSIONAL SPACE INFORMATION AMONG PLURALITY OF TERMINALS AND READING COMMAND EXECUTION POINT
Document Type and Number:
WIPO Patent Application WO/2021/137348
Kind Code:
A1
Abstract:
The present invention relates to a method by which a plurality of terminals generates a space map in order to share three-dimensional space information among the plurality of terminals and reads a command execution point, and, more specifically, to a method, which combines image features acquired from continuous color images and sensor information acquired from a gyro sensor, so as to generate three-dimensional space information, transmits/receives same to/from a server through socket communication so as to synthesize fragmentary space information obtained from a plurality of terminals, thereby generating and sharing extended space information, obtains continuity for the augmentation of real space, projects two-dimensional coordinates inputted by a user through a touch screen on each terminal to three-dimensional space coordinates, so as to transform the projected three-dimensional space coordinates into three-dimensional coordinates in real space, shares same among the plurality of terminals so that the plurality of terminals can simultaneously augment the same virtual object at the same location.
