Preset Mode


Processing the data in Preset mode allows to go step by step along the following processing phases using the presets offered for each one.

1. Odometer

2. Tracking odometer [optional and only available with Tracking add-on]

3. Create Maps

4. Global Optimization

5. Clean Data [optional]

6. Go to Reconstructor



Presets

All the processing steps in Mapper can be performed using standard presets already saved inside the software.

Even so the customer can create other presets, according to his needs, by using the following commands:

Create new PRESET from currently displayed settings 

Delete currently selected preset from the list

Import a preset from an external source

Export currently selected preset to be used in another system



1. Odometer

This process re-calculates the trajectory by clouds registration.


Preset

When use it

Indoor

for all data acquired by HERON in typical indoor environment

Outdoor

for all data acquired by HERON in typical outdoor environment

CriticalAreas

by EITHER following Odometer process or a quick check after Odometer process is done, when there is a drift which is noticed by Red color on the trajectory or strange shape of the computed trajectory, use this preset to solve. 

LargeOutdoor

for data which is acquired in outdoor environment where there are very few objects and/or poor geometry quality

Tunnel

for data which is acquired in tunnel (excavated, underground and/or aboveground, and concrete tunnels)


The  CriticalAreas preset, can be carefully used when other presets failed (e.g. presence of large moving object, too rapid transitions between environments with very different geometries) . This preset must be used limited to these critical point and not extensively along the trajectory.


2. Tracking odometer

This process re-calculates the trajectory by clouds registration, every individual point cloud acquired by the system will be directly aligned with reference model getting the final global accuracy as close as the accuracy of reference model.

A reference model can start from a 3D mesh, static/mobile point cloud, BIM/CAD and other 3D data which can be imported in Reconstructor.


Preset

When use it

Standard



3. Create Maps

This process creates a set of maps by splitting the full trajectory into a set of Local Maps.  They are used, subsequently, to align the model.


Preset

When use it

10 meters - 10 cm

for typical indoor environment

10 meters - 5 cm

for indoor environment which is big and has few objects/geometries

25 meters - 10 cm

for typical outdoor environment

25 meters - 5 cm

for outdoor environment which is big and has few objects/geometries


4. Global Optimization

This process globally registers (aligns) the local maps created by Create Maps. Static scans imported in the project can be also included in the Global Optimization.


Preset

When use it

Standard

1. for data using 

- External constraints, i.e. points, GCPs, static scans, external and georeferenced point clouds

2. for initial steps in Global Optimization operation: i.e. manual connection, automatic connection, connect trajectories together

StandardGravity

For last step before finishing Global Optimization operation, HERON Desktop will use all resources acquired by the system to adjust the verticality of the final point cloud


5. Clean Data

This process cleans the maps isolating moving object data (as for example people walking, moving cars, etc.) from the point clouds.

It is an optional step and must be run only after the Global Optimization process.


Preset

When use it

Standard



6. Go to Reconstructor


This process directly exports the results of a Global Optimization process ready to be imported in the Reconstructor® project (as a Heron® Survey).

Also relative trajectories, cameras and tags are exported within the point clouds.


Preset

When use it
