How to align the surface model into horizontal plan?
« on: October 25, 2021, 02:06:23 PM »
Excuse me everyone, I am using Agisoft to construct 3D pavement surface texture. When I do it, the surface model is not fit into horizontal plan direction as show the attachment (Picture). How can I solve this problem ?

Hi,
If I understand what you want correctly, you want the fllor to be aligned level and squared up to the world and grid. and to be at the grid and not below or above it. then do this :-
You need to use ortho views as follows.
A. hit numpad 5 that toggles perspective or ortho, it says so in top left corner. get it to ortho.
B. hit numpad 7 thats top view, get tool 'rotate model'  and rotate it squared up to grid.
C. hit numpad 1 and rotate it to be ok there (there is no grid, we need one, meaanwhile have to use edge of screen, bit prehistoric, agisoft please give us a grid in 1 and 3.
D. hit 3 and sort it out there.

right mouse button will pan, drag across screen.
middle scroll wheel for zoom, I also found shift and left mouse button did so.

now to do the region box. make it to fit around but just outside your model.

same steps A to D  this time using tools for move region, rotate region, resize region.
the translucent red of the box is the base of the box so that should be just under your floor.

E. Then using 1 or 5, you see a thin black line, thats the grid seen sideways on, move the floor using move model tool, the box moves as well., until it is on that line.

The sphere unfortunately does not have its coloured rotate lines remapped to ortho to allow us to rotate perfectly in ortho, constrained to a planar rotation.
we need a reset sphere to ortho view. Agisoft please fix this.

as such some rechecking and further rechecking in ortho views is required.

Hope that helps

Steve

Dear Steve,
I appreciate your kindness response, thank you very much. I know about the shortcut number for viewing the facad. If I compare to the plan XYZ, I found that one plan is slope not corresponding to the plan as show in the picture attachement. My purpose is want to automotatic rotate correpsonding to the plan ( do not want to get the slope). Because I am using Python Agisoft API for generating the dense point cloud and depth map. Therefore, it is neccessary to get the real distance for point cloud computation. Thank you very much.

Best Regards,
