影像反求的3D图解研究

The 3D graphic method of image reverse

提出一种从影像图片中反求获得原型的3D图解方法。基于Solid Works软件建立透视空间,导入原型照片,通过设定影像轮廓的关键点获取透视的灭点;进而建立视线与影像的几何关系,反求出原型。3D图解法较2D图解法更加直观和高效,其演绎的"描边法"更将专业的图解法简化为一种普通的描边操作。

A 3D graphic method which reverses to acquire its prototype from the images is studied. Perspective space which is based on SolidWorks,imports the prototype photos, by setting the image contour key points for the perspective of the vanishing point ,thus it builds up the geometric relation,and then establishes the line of sight and image and reverses out the prototype. 3D graphic method is more intuitive and efficient than 2D one; the deductive method of ＂ stroke＂ will simplify a more professional graphic method and turns it into a common stroke operation.
