Disclosed herein is an apparatus and method for automatically creating a 3D personalized figure suitable for 3D printing by detecting a face area and features for respective regions from face data acquired by heterogeneous sensors and by optimizing global/local transformation. The 3D personalized figure creation apparatus acquires face data of a user corresponding to a reconstruction target; extracts feature points for respective regions from the face data, and reconstructs unique 3D models of the user's face, based on the extracted feature points; creates 3D figure models based on the unique 3D models and previously stored facial expression models and body/adornment models; and verifies whether each 3D figure model has a structure and a shape corresponding to actual 3D printing, corrects and edits the 3D figure model based on results of verification, and outputs a 3D figure model corresponding to 3D printing.

Disclosed herein is a 3D model shape transformation apparatus. The 3D model shape transformation apparatus includes a camera unit, a shape restoration unit, a skeleton structure generation unit, and a skeleton transformation unit. The camera unit obtains a plurality of 2D images in a single frame by capturing the shape of an object. The shape restoration unit generates a 3D volume model by restoring the shape of the object based on the plurality of 2D images. The skeleton structure generation unit generates the skeleton structure of the 3D volume model. The skeleton transformation unit transforms the size and posture of the 3D volume model into those of a template model by matching the skeleton structure of the template model with the skeleton structure of the 3D volume model.

The present invention relates to a hydrothermal synthesis for preparing barium titanate powder as the essential material for a multi-layer ceramic capacitor. The object of the invention is to prepare barium titanate powder having high purity, particle size of submicron order, uniform particle distribution and excellent crystallinity, by reacting hydrous titanic acid compound prepared via sulfuric acid process with crystalline titanium oxide and barium hydroxide, as the starting material, at a temperature between 60&#xb0; C. and 300&#xb0; C. under a pressure between 5 Kgf/cm2 and 50 Kgf/cm2. The process for preparing barium titanate according to the present invention provides barium titanate powder having Ba/Ti molar ratio of 1.000&#xb1;0.002 and high purity by applying calcination under reductive condition to the solid product obtained from hydrous titanic acid compound prepared via sulfuric acid process with crystalline titanium oxide and barium hydroxide, as the starting substances, to convert barium sulfate, which was produced from residual sulfide in the raw material, to barium titanate.
