  • Patent number: 10229539
    Abstract: The system includes imaging unit which images a work space at a viewpoint position in a visual line direction of a worker together with an other component to which one component is to be installed, a position attitude information obtaining unit which obtains position attitude information which indicates relative position attitude relation between viewpoint of the worker and other component in the work space, a virtual image generating unit which generates virtual image of an actual shape of the one component at the viewpoint position in the visual line direction of the worker based on position attitude information, an image composing unit which generates composite image by superimposing virtual image on a real image in the work space imaged by the imaging unit, and display unit which displays composite image. According to the system, efficiency of component assembly work can be considerably improved by using mixed reality technology.
