專利摘要

A 3D model reconstruction acquisition includes the steps of preparing a transparent container and at least one image capture device, wherein an object is placed in the transparent container and a liquid is received in the transparent container; keeping the liquid level rising or lowering to allow the liquid level to pass through a surface of the object and then keeping capturing a series of the images; computing a liquid-level equation for each of the images by using curves of the images between the object and the incremental or decremental liquid level confined by the transparent container; computing 3D coordinates of the curves in accordance with the liquid-level equation of each image; and collecting 3D coordinates of all of the curves to create a 3D model of the object. In addition, the acquisition can be done in the environment having water and thus be applied to various environments.
