Abstract: A method of constructing a hollow wall structure comprising: a step (A) of constructing a grout wall mold; a step (B) of grouted a curable liquid material into the grouting space; a step (C) of removing the first template wall and the second template wall so as to produce a semi-finished hollow wall having the Styrofoam board; and a step (D) of removing a semi-finished hollow wall having the Styrofoam board so as to obtain a hollow wall having a communication space. The communication space has an inflow conduit and a connection channel.

Abstract: A camera device comprises more than three image capture modules used to capture more than perspective images of a 3D (3-dimensional) object; and an administration module electrically connecting with the image capture modules, receiving and administrating the perspective images of the 3D object. The present invention uses the image capture modules to capture the perspective images of the 3D object from different shooting angles and synthesizes the perspective images of the 3D object into a 3D panoramic image of the 3D object. Besides, the present invention can precisely obtain the dimensional information, such as the size, length and width, of the object in the image. Therefore, present invention can effectively promote the quality of 3D panoramic images of a 3D object.
