从两个 bundle.rd.out 取出两个模型中对应的三个点
经过平移缩放后，模型差不多已经重合，但是总还一点点
d1 0:x,y,z=0.000000,0.000000,0.000000
d2 0:x,y,z=0.000000,0.000000,0.000000
第一点都放在原点，没问题了
-----------------
d1 1:x,y,z=-1.230783,0.000000,0.000000
d2 1:x,y,z=-1.230783,-0.000000,-0.000000
第二点放在x轴上，也重合了
-----------------
d1 2:x,y,z=-0.132257,-0.351321,-0.351321
d2 2:x,y,z=-0.129898,-0.346410,-0.346410
第三点不对，这是什么原因？？？？
-----------------
图上好象分得越来越开

d1 0:x,y,z=0.000000,0.000000,0.000000
d2 0:x,y,z=0.000000,0.000000,0.000000
-----------------
d1 1:x,y,z=-1.230783,0.000000,0.000000
d2 1:x,y,z=-1.230783,-0.000000,-0.000000
-----------------
d1 2:x,y,z=-0.132257,-0.351321,0.000000
d2 2:x,y,z=-0.129898,-0.346410,0.000000
第三个点x,y坐标不同
这个不是应该是相似三角形吗？
