Method and system for remote collaboration

A method for a remote collaboration, as a method for providing an augmented reality (AR)-based remote collaboration between a robot located in a worksite, a field worker terminal, and a remote administrator terminal located outside the worksite, the method comprising:

• acquiring a captured image including a field image captured by a robot located at the worksite or a captured image including a user image captured by the field worker terminal;
• displaying the captured image of the worksite;
• generating virtual content based on an input of a remote administrator and a field worker with respect to the displayed captured image;
• and
• displaying an AR image in which the virtual content is augmented on the displayed captured image,
• wherein the displaying of the AR image in which the virtual content is augmented on the displayed captured image includes at least one of displaying the AR image in the field worker terminal;
• displaying the AR image in the remote administrator terminal;
• and the AR image on a display device disposed on the robot,
• wherein the display device is a computing device detachably disposed in a body of the robot and connected to the robot for wireless or wired communication, and the acquiring of the captured image includes acquiring a sub-field image captured by the display device detachable from the robot, and
• wherein the generating of the virtual content based on an input of the remote administrator and the field worker for the displayed captured image includes:
• displaying the field image in the remote administrator terminal and generating the virtual content according to the input of the remote administrator from the displayed field image, and
• the displaying of the AR image on the display device disposed on the robot includes displaying an AR image in which the virtual content is augmented on the field image captured by the robot.
