This paper researches and designs a software named test3d . the following is the main ideas : firstly , it should become the linked part between measurement system and 3d cad system . then , it should can reconstruct surface from point - clouds directly in order to output surface model that can be used by cam software directly 本論文研究設(shè)計一個test3d軟件,其設(shè)計思想是:第一步作為三維掃描儀器和三維cad軟件的接口模塊,搭起二者之間的橋梁,然后在此基礎(chǔ)上研究直接由點云做面的處理方法,目的是通過對點云處理后能直接輸出可供cam軟件使用的曲面模型。
