The mixed reality based 3D sketching device includes a processor; and a memory connected to the processor. The memory stores program commands that are executable by the processor to periodically tracks a marker pen photographed through a camera, to determine whether to remove a third point using a distance between a first point corresponding to a reference point, among points that are sequentially tracked, and a second point at a current time, a preset constant, and an angle between the first point, the second point, and the previously identified third point, to search an object model corresponding to a 3D sketch that has been corrected, after correction is completed depending on the removal of the third point, and to display the searched object model on a screen.

A 3D geometry enhancement method and an apparatus therefor. A random forest regressor is built using sketch patches and displacement patches, wherein the displacement patches are patches corresponding to the sketch patches and placing on a displacement map of a 3D geometry model. A new sketch is received. Displacement patches respectively corresponding to sketch patches are extracted by applying the sketch patches extracted from the new sketch to the built random forest regressor. A displacement map with respect to a 3D geometry model is generated using the extracted displacement patches. The generated displacement map is applied to the 3D geometry model.
