orthocentric tetrahedron

In this dissertation a graphic positioningmethod is proposed to adjust all the many dimensional parameters synthetically, ahollow tetrahedron is used for a positioning target to replace all the edges of astandard automobile body.

针对这一关键技术,提出了对多维参数进行综合调整的图形定位方法,在该方法中采用了空心正四面体的棱边代表标准汽车车身的棱边来设置传感器,即在没有标准车身的情况下,由正四面体的棱边画出了虚拟的标准车身,故又称为虚拟定位技术。
