  • Patent number: 10600244
    Abstract: The present invention relates a vertex optimization method and system using a depth image in workspace modeling, the method including generating a workspace model by scanning a workspace and modeling the workspace; generating a vertex image by projecting vertices in the workspace model generated in the scanning of the workspace; generating a depth image by expanding the vertices in the vertex image generated in the generating of the vertex image; and resampling the workspace model generated in the generating of the workspace model using the depth image generated in the generating of the depth image. Accordingly, the depth image can be generated from a vertex image obtained by projecting spatial data scanned through a 3D scanner onto a virtual wall, thereby uniformly aligning non-uniform vertices and filling gaps in which no vertices are generated.

  • Publication number: 20190196590
    Abstract: The present invention relates a haptic tool system, the system including: a computer device portion providing a content image including a target object for user testing or learning through a haptic feedback simulation function; and a haptic drill tool having an capacitive touch pen that makes contact with the target object and providing a haptic feedback simulating use of an actual drill to the user on the basis of load cell displacement information on a force applied according to the contact of the capacitive touch pen and physical property information on the target object. According to the haptic tool system, it is possible to provide the haptic feedback similar to a force and a motion sensation that the user feels when using an actual electric drill.
