Blueprint Navigator


To visualize a blueprint map and the relative Heron® point cloud; also camera information is displayed for data from HERON systems with camera.




The window is subdivided into two main areas: the 3D view showing the colored point cloud (and the cameras colorization) and the associated blueprint(s).

In the bottom area are the navigation commands, below explained.



Close the Blueprint Navigator

To close the Blueprint Navigator viewer.

Detach the Blueprint Navigator to a separated window

To detach the blueprint 2D image to a separated window and show the full screen 3D view.


Open the Heron Survey Editor

To open the tool that creates/edits the selected Heron Survey.


By clicking on the below buttons a different color visualization is displayed:

Disable panorama

To make the panorama image fully transparent, displaying only the point cloud.

Show panorama and point cloud

To make the point clouds visible through the panorama image.

Show panorama only

To make the panorama image fully opaque, hiding the point cloud data.

The next slider permits to make visible the intermediate views (from 0 to 100% of image opacity).



Layers

To choose the current layer and blueprint, if more than one trajectory is related to the same Heron Survey.


Trajectories

To choose the current trajectory, if more than one trajectory is related to the same Heron Survey.


Cameras

To choose the current trajectory camera.

If no cameras are available only a message is visible here.


If during single-shot acquisitions the surveyor moves quickly or the ambient light changes suddenly, it is possible that the corresponding image is not correctly time aligned with the point cloud acquisition.
In this case you can manually adjust the position of the camera along the trajectory, by using the Adjust camera time offset [Ctrl+Shift+T] command. 
It is firstly suggested to set the spherical camera overlay opacity which best allows you to see the overlap between cloud and spherical image, then change the Camera time offset parameter (the default value is -0.7 seconds) in order to find the best overlapping between image and point cloud.

Once found it you can use this setting only for the current camera or for all single shots cameras in the trajectory. 
Click on to confirm the changes.



Previous trajectory

If more than one trajectory is present, jumps to the previous one in the current Heron survey.

Previous camera

Jumps to the previous camera along the trajectory.

Next camera

Jumps to the next camera along the trajectory.

Next trajectory

If more than one trajectory is present, jumps to the next one in the current Heron survey.



Play/Stop

To start playing or pause the current trajectory.


00:05:22.569

Follow camera trajectory direction

To jump to a specific timestamp.

By clicking on it a window will appear, showing the time information about the trajectory and the absolute/relative (respect to the beginning of the Survey) timestamps to set.



Follow camera trajectory direction

To toggle weather to adjust the view direction automatically while moving to a camera position.


The next slider permits to quickly change the position along the trajectory. It also indicates the current position during the playing.


In the left side of the navigation bar different zoom levels can be applied on the blueprint:


Zoom Out

To decrease the blueprint zoom level.

Zoom In

To increase the blueprint zoom level.

Zoom to Fit

To zoom to fit the entire blueprint.

Zoom 1:1

To zoom to the blueprint pixel size.
