This project looks at developing a UI-based tool for using the Helios++ (https://github.com/3dgeo-heidelberg/helios) LiDAR simulation project for UAV task planning.
The Helios++_UI is delivered to you in a zipped folder, unzip the folder to your working directory. This folder contains Dockerfile to build the docker image for running this project. The folder also contains some predefined scanners and platform settings and definitions (please do not modify these files!!!). The predefined scanners and platforms are available on the front end for editing and working with. You can add new scanners and platforms from the front-end as well as modify existing scanner and platform settings. More information is available on the wiki. Finally, the whole GUI code is in several files and folders in this directory.
In the directory (base directory) that contain the Dockerfile, run the following code
docker build -t 3dhelios .
docker run --rm -it -p 5000:5000 3dhelios
Open a web browser and run:
localhost:5000
You can select from the predefined scanner and platforms that comes with the Helios++_UI or you can define a new scanner or platform. You can also modify existing scanner and platform settings/definitions. The information below is for adding new scanner and platform.
Refer to Helios++ repository for a full definition of each of the parameters needed.
The scanner settings information is available at https://github.com/3dgeo-heidelberg/helios/wiki/Scanners#scanner-settings
The platform settings information is available at https://github.com/3dgeo-heidelberg/helios/wiki/Platforms
Additional information on the individual parameters of the survey is available at: https://github.com/3dgeo-heidelberg/helios/wiki/Survey
Using the blender2helios (available for download here: https://github.com/neumicha/Blender2Helios) addon in blender, perform the following steps:
Helios Base Directory:
Create a directory called new_blender2helios_scene
Create a directory called data inside new_blender2helios_scene
Create two directories inside data called screens and screenparts
In blender2helios: provide new_blender2helios_scene as the helios base directory
In blender Go to the Render tab and run blender2helios Export as shown
Zip data and upload to web-helios++

The Download button will become active when Helios have finish running. Download the output to have access to the results. The format and explanation of the output is available at https://github.com/3dgeo-heidelberg/helios/wiki/Output
The downloaded output point clouds and (optionally) the full waveform and the trajectory files are stored in
[survey_name]opt/gui-helios/helios-plusplus/output/Survey Playback/[name of survey as defined in survey.xml]/[time stamp of simulation start]/points/[number of scan position].
