Project window - Project manager
With the project window all data of an ELCOVISION 10 project can be viewed and modified. It is the central control element of ELCOVISION 10. Several project windows can be open at the same time for the same project, e.g. to see the point cloud and the thumbnails of the images at the same time.
It is divided into 3 areas:
|  |
Project
All kinds of statistical information about the project is displayed here. The display of the location of the project file is particularly helpful.

2D view: Thumbnails of all digital images
Double-click on the corresponding thumbnail to load the image.
Rotate images legibly
Images must not be rotated externally, e.g. with the Explorer! In order to have images readable nevertheless, e.g. for manual measurements, they can be rotated via the context menu of the thumbnail view.
Sort images
Via the context menu, the images can be sorted in ascending order according to the image number
