Setting up a Project

The following steps show how to setup a measurement project manually:

Step 1. Create a new project, File > New >New Project. The project name by default is “project0” In Project Explorer, right click on the “project0” and Reload Project.


Create a new solution. Add a new project to the solution.
Create a new solution. Add a new project to the solution.
Step 2. Add a camera, right-click' on the Spherical Panorama Camera in the Project Explorer and click on Add Camera. Sensor is added to the Project Explorer.

If your project consists of more than one camera, you can add them by repeating Add Camera.

Step 3. Add images to your sensor,right-click on the Images under your Camera and click on Add Image(s) > Add Image(s) Browse and select the image files that belong to this camera.

A dialog box appears to fill in the camera setting parameters. Press OK. By clicking on Images you will have the list of all project images in Report View.


Add images to the project.

Add images to the project. The images with the extention different than “.pci” will be inactivated in the project.

Step 4. Up to this step the essential part of the project has been configured. The project can be saved on hard disk. Right click on the name of project which is currently “project0”:
Up to this step the essential part of the project has been configured.


Step 5. Up to this step the essential part of the project has been configured. However, if additional data are available, they can be imported into the project. The following additional data can be imported through Import menus which are accessed by a right-click on relevant items at Project Explorer:
Reference points.
Control points and check points.
Reference points. Control points and check points.
Camera parameters. Image points.

Accessing Project Data and Results

FOVEX 360S Graphical User Interface (GUI) provides 4 different views (tabs) for accessing data and results:

Accessing Project Data and Results


Image View It displays the image content and related measurement data. To view an image, double-click on the Image item in the Project Explorer.
Network View It displays the 3D measurement network including camera stations, 3D points, error vectors and CAD objects.
Report View It displays the content of the item at Project Explorer in tabular and text forms. The tabular or text forms of the items at Project Explorer are shown in Report
Layer View It displays the defined layers for the project. To view content, click on Layer View tab.

Image Orientation

Image orientation means finding the most accurate estimate for three orientation angles (w, phi, and kappa) and the 3D coordinates of the location of the camera stations. These 6 parameters are called exterior orientation parameters of an image.

Estimation of these parameters does not require external information such as distance between camera stations or the location of the image points in 3D.

Automated with Natural Features

The quality of image orientation with this method depends on the quality of the extracted features in the image. The following steps provide necessary information to orient images successfully.


Step 1. From the toolbar press on Auto Process with Natural Features (Auto Process toolbar).

Auto Process with Coded Targets

The result of Auto Process with natural features. The network does not have yet a proper scale.

Step 2. Scale of the network can be recovered by manual scale-bar definition.

This process has been explained in the section “Add Scale Bar”.


Note: The group of Feature Detection & Matching parameters influences the results of feature detection and matching. This group of parameters can be accessed from Project Explorer the Settings of the project:

Manual with Image Point Measurement

This method needs the interaction and supervision of the user. It is suggested for the projects in which good quality of natural features are not available. The following steps provide necessary information to orient images by manually measurement of the image points:


Step 1. Open two images which have sufficient (>50%) overlap from the list of images at Project Explorer. These two images should not be taken from an identical location.
Step 2. Measure at least five corresponding image features among these opened images and associate unique but corresponding labels to them. Choose your image points such to spread them across the image. Image features can be measured by using the “Draw manual point” at the toolbar of the Image View:

Correspondence of image feature measurement is defined in FOVEX 360s by giving a unique label to the corresponding features. For example, “A0” in the following:

The following Figure shows all the manually measured corresponding image points at two different images:

Step 3. Perform Orient Images. Orient Images can be accessed from the Adjustment toolbar:

Perform Orient Images


After a successful image orientation, the decoration symbol of the image at Project Explorer will become green:

After a successful image orientation, the decoration symbol of the image at Project Explorer will become green:


If the images are not oriented, you need to measure more corresponding image features similarly as explained at step 2.

Step 4. If the number of corresponding image points is more than 12 and still the images are not

oriented, go to step 5. Before going to step 5, double check if all image points are corresponding to each other.

Step 5. If all images are oriented or you would like to stop building network process, then go to 7.
Step 6. Open the next non-oriented image (with a red decoration color) and go to Step 2.
Step 7. End of image orientation. The following figure shows the result of image orientation for this project which was consisted of 4 images:

Scaling the Project

The final step of the creation of a 3D measurement project is scaling the project. Scale-bars can be added to the project in three ways. Click on Scale Bars at Project Explorer and go to the tab of Report View. Right Click on the middle of window and select Add Scale Bar. The next sections describe possible ways to adding scale to project.

Scaling the Project


Context menu of Scale Bars at Report View: the addition of a scale bar to the project.

Add Scale Bar

By clicking on Add Scale Bar a tabular form is displayed as follows:

Add Scale Bar


The following information should be given for each scale bar:

  • A unique ID of the scale-bar
  • The first ID of scale-bar end point 1
  • The second ID of scale-bar end point 2
  • Calibrated temperature, if available
  • Calibrated length of the scale-bar
  • Standard deviation (uncertainty) of the scale-bar length

Click on the Active Check Box and the project will be scaled to the size of the given scale bar.


Add Scale by Camera Station

By clicking on Add Scale by Camera Station the following dialog box is displayed:

Add Scale by Camera Station the following dialog box

Provide the distance between up & bottom camera stations and Press “Add”. The project will be scaled automatically with the given length of scale-bars.
