How to tilt the plane of reconstruction to XY plane?

Hi Andrea, I tried your up vector by plane method. It did not work. I don't know what I am missing. Can you help?

Wow! I am very impressed! Thanks Andrea for explaining this neat trick. I have two other questions:

1. Is there a scripting tool that would enable me to read image files in a folder, create dense clouds, and store the point cloud in another directory, for example in ..obj format?

2. Is there a nice way to segment the reconstructed object and the floor plane point cloud so that the reconstructed object can be stored without any intervention from the user?

I am trying to create a pipeline using Zephyr as a front end processor and my matlab code to post process. Any help is really appreciated.

After struggling with matlab photogrammetry scripts, I really admire what you have accomplished. Wonderful contribution!

Hello Victor,

you have a few options:

- in Pro and Aerial, you can eventually use control points (if available)

otherwise, in all versions you can use the following tools:




- up vector by two axis: the up vector is defined as the result of defining first the X and Y axis. Select the origin point (left click), then a point to define X axis with another left click (origin -> X) and then another left click to define the Y axis ( origin -> Y). The resulting axis is automatically computed.

- up vector by plane: (personally my favorite ) - define the ground plane by selecting three points (in your case, the floor or the top of the box, for example).

- up vector by two points: select the up vector by clicking the two points that would define it (in your case, the wall)

- use the gizmo to manually rotate all structured items: use the rotation tool or input the transformation manually

I just did a reconstruction using 48 images of an ornamental jewel box. The reconstruction dense point cloud is oriented on a tilted plane as shown in the attached image. How do I change the orientation to coincide with XY plane? Is there any other tool that can do that?
