Control point workflow

    Hi Massimo,

    Sorry, wrote this 5 days ago but forgot to send...  duh

    Are you talking about Ground Control Points with known coordinates?

    Then there is a glitch that you can exploit - as soon as you add one Point in any GCP, the point appears in 3D.

    Once the model is roughly geo-referenced (as you suggest in your workflow) they will be in the right spot in the sparse point cloud.

    Another possibility is using the pivot point, you can activate it in the Image tab. You can locate it anywhere in 3D by double clicking on the point cloud. Also, it will then appear in the 2D images and you can spot your targets much easier.

    Last but not least, you can select the Similarity filter in Scene under 2Ds view. That can sometimes help too.

    I'll test the suggested workflow. Selecting the points is extremely time consuming.

    On the other hand I really like the pixel error report and the way selection in the picture works.

    Thanks again,
