Dataset Artifacts

The following artifacts are output by the NavVis software for each individual Dataset .

If you record multiple Dataset s for your Site , you must align them. The alignment process creates two main artifacts in the datasets_web folder : A bundle XML file : This file stores information on how the datasets of an IndoorViewer inst...

2D geo-registration maps are generated during post-processing for every Dataset and are output in 10 cm and 2 cm resolutions. These maps provide outlines of the mapped site and serve as basis for refinement in drawing programs. A pixel represents ...

2D x-ray maps are generated during post-processing for every Dataset . These images are rendered from different viewpoints (top-down and side views) with a resolution of 5 cm / pixel. As a result, they provide useful information about mapped buildi...

During mapping, the mobile mapping system captures signals from Bluetooth beacons. During post-processing, this information is written to bluetooth_beacon.csv i n the form of tupels containing the following information: The timestamp (in secon...

The file sensor_frame.xml stores the calibration parameters of the mobile mapping system including cameras, laser scanners, and electrical devices. Warning: This is a critical file. Do not modify, rename, or move it to a different location...

In the /info subdirectory, there is a JSON file XXXXX-info.json for each successful capture event. datasets_rec/

The logs directory contains log files recorded during mapping (in the datasets_rec folder) and during data processing ( datasets_proc and datasets_web ).  The information in these files is important for Troubleshooting .

For every Dataset , the file trace.csv contains position, orientation, and magnetic field information in frequent intervals. This is an example of what the file looks like: #nsecs, x, y, z, ori_w, ori_x, ori_y, ori_z, mag_x, mag_y, mag_z 1...

The post-processing generates high-quality panoramas with a resolution of up to 32 megapixels and a full field of view (360° horizontally + 180° vertically) to provide an immersive virtual 3D experience. The final images are computed using the ...

The file pano/pano-poses.csv explicitly  stores collected information about the poses of each panorama. Here is an example file with poses for five panorama images: # pano poses v1.0: ID; filename; timestamp; pano_pos_x; pano_pos_y; pano_p...

After scanning buildings and facilities with a NavVis device, the 3D structure of the scanned environment can be generated as a Point cloud . The point cloud can be imported into 3D viewers, CAD programs or any other 3D modeling application which...

The quality map visualizes the quality of the mapping: it shows the trajectory estimate and capture locations and indicates the density of the Point cloud by showing densely scanned areas in different colors. Dark blue indicates floor covera...

During the scan, the device captures WiFi signals and stores the access point identifiers and signal strength. One file named XXXXX-wifi.log is stored per capture event, where XXXXX is a placeholder for the capture location's number. The...
