调入点数据(1/2)
Cloud import :
在使用这个模块时,首先就需要将数据调入 CATIA
选择输入文件:
可以在此栏中进行格式选择
格式:
Direction 和 Delimiters 用来进行 scans.
Atos 是控制点的质量(去除无效点), 数值从 0 到 255 (由低到高),那么低于此值的点将被忽略。

Remove:
从点云上去除点。
Inside Trap:
Outside Trap:
Selected Part , 选择方向:
Pick : 点选
Trap: 框选
Selection :
点一旦去除就不能再恢复。
Select all 选择所有点
Swap 选则转换
Global :
Level: In coordination with Pick can be set to:
Point Scan/Grid Digit Cloud Triangle

Filtering:
过滤
Homogeneous: enter the value of the Sphere radius, used to filter the points. The filtering sphere is visualized by a green sphere. You can change its position by a simple mouse click at a desired location
点是被隐藏而不是去除。
只能对最后一步Undo 。
不能对 tessellated 或 polygon点云数据进行过滤。
Statistics will be then displayed, that is :
Before application, The number of points to be processed.
After Application, the number, and the percentage of the remaining points
物理去除
Physical removal :
Adaptative : The value to enter represents the local chordal deviation.
This filtering hides more points from the planar areas than from other areas. That way, you can highlight bent areas.

Activate:
从点云上激活所选择的部分
Inside Trap:
Outside Trap:
Selected Part , it can be:
Pick : will allow to select by picking elements on screen. The element type is filtered by the options from Level
Trap: Will allow the selection through a contour trap see explanation on trap type. The trap is drawn in a plane but has a depth. Then you may change the trap by the manipulators of the Trap.
Selection :
Activate all 激活所有点
Swap 激活没有选择的点
Global :
Level: In coordinat
