Automatically align a 3D model with a point cloud

In order to be able to use automatic alignment, you must have a 3D model already present on the viewer.

Click from the scene menu on the name of your 3D model. (double click to stand in front of the model if necessary)


Scroll down until you find the ALIGN button and click on it.

A new window will open.


To achieve the automatic alignment correctly, you must place 6 points, always in pairs, respecting the colors displayed on the board.

We will first start with the left table points to align (3D model), you can click on the eye in order to hide or show the 3D model.

Click on the A0 line and place the point on the 3D model. Once the point is placed, you will see its coordinates in the table. If necessary, you can move it at any time by simply dragging it in the viewer. Do the same thing for the R0 line and select the equivalent point on the point cloud.


Then continue to place the other two points on the 3D model and end up placing the other 3 points on the point cloud.

Attention, the point A0 of the 3D model will be linked with the point R0 of the point cloud (always in pair). You must respect the order in which you placed the points.

Once the 6 points have been placed, you can check "Adjust the scale” so that the 3D model adapts to the point cloud.

If the placed points look correct, you can click on Align and the 3D model will automatically align itself with the point cloud.


If you want to remove the 6 alignment points, click clean, this will allow you to restart the procedure.


The model and point cloud have been aligned !
