Abstract: A vehicle body flaw elimination method using a virtual mark, includes: detecting, by a robotic visioner, a flaw formed on a vehicle body surface and outputting corresponding flaw data; forming, by a controller, a virtual marker corresponding to the flaw data on a 3D model corresponding to the vehicle body; transmitting, by the controller, data of the 3D model on which the virtual marker is formed to a wearable device; and detecting, by the controller, a position of the vehicle body and a position of the wearable device to identify the position of the vehicle body and a position of a worker wearing the wearable device, and modifying the 3D model of the wearable device in a direction in which the worker views the vehicle body.

Abstract: The present invention provides an earth anchor bracket supported by a girder coupled to a side surface of an earth wall to fix a free length of an anchor body inserted into a boring hole formed at the earth wall according to an earth anchor method. The earth anchor bracket of the present invention includes two side plates each including a curved portion including saw-teeth and facing each other; a coupling material coupling and fixing the two side plates; and a pressure bearing means, supported by the two side plates and including obstacle protrusions engaged with the saw-teeth of the two side plates and a through portion withdrawing the free length of the anchor body.
