How to orient a project

  • In order to orient a project, step 1. Initial Processing has to be completed.
  • If the project has images with geolocation and the Orientation Constraint is too different from the orientation given by the image geolocation, the Orientation Constraint will not be taken into account. If the orientation given by the image geolocation is inaccurate, the geolocation should be removed to orient the project. For more information about the image geolocation: Menu Project > Image Properties Editor... > Image Geolocation.

In order to orient a project, an Orientation Constraint need to be defined in the rayCloud:

1. On the Menu bar, click View > rayCloud

2. On the Menu bar, click rayCloud > New Orientation Constraint.

 3. In the 3D View, a white circle appears beside the mouse. Left click to insert the first vertex. 

  • An Orientation Constraint has direction and is defined by a line connecting 2 vertices.
  • For each vertex a Manual Tie Point is created.
  • When drawing the Orientation Constraint, a vertex used by other objects can be reused for the new Orientation Constraint, by clicking on it while drawing the Orientation Constraint.

4. Right click to add the last vertex and to create the Orientation Constraint.



5. Select the Orientation Constraint in the 3D View and correct the position of the vertices in the images: How to edit Objects in the rayCloud.
6. In the Selection section of the right sidebar, select the Axis and enter the Angular Accuracy.

Note: The Orientation Constraint is by default drawn for the Z axis and with the default angular accuracy. These values can be changed after the constraint is added.

7. (optional) Click Flip to change the orientation.
8. Click Apply to save the changes.
9. (optional) Add more Orientation Constraints following steps 2. to 8.
10. Click Process > Reoptimize to orient the project.

    Hi. I have been trying to correct my pictures location. The mergede images are positioned about 25 away from the correct location. Is there a way to move the mergede pictures to the right location on the map.

    Hi Marin. Generally the inaccurate geotags are corrected using GCPs which are survey points that are more accurate than the drone GPS. Check out the Using GCPs page on the knowledge base if you haven't encountered GCPs before.
