Recorded Data

Recorded datasets capture everything collected during a scan, from images and sensor data to control points and quality maps into a single, time-stamped folder. This page explains the structure and contents of that datasets_rec/<date-time> folder, so you know exactly where to find anchors, images, sensor data, calibration files, and other key information needed for processing and use in NavVis IVION.

While scanning, images and sensor data are recorded. From the moment you start scanning until you press Finish, everything is written to one Dataset, which is a folder containing a number of individual files.

For each Recorded dataset, a corresponding folder is created named datasets_rec/<date-time>.
A Recorded dataset contains the following folders and files:

Folder/File	Description
`anchors/`	Contains text files with control point information.
`anchors/anchors.txt`	Contains the timestamps and names of Control Points entered during the scan. See also Dataset Control Point Info File.
`anchors/anchor_poses.txt` or `anchor_poses.csv`	Contains the measured poses of control points. See also Control Point Poses File.
`anchors/anchor_poses_recorded/txt`	Contains the poses for Control Points as recorded during the scan.
`cam/`	Contains captured images.
`cam/info.list`	Lists the `*info.json` files created inthe `info/` folder.
`info/*.json`	An `*info.json` file (see Capture Location Info Files) is created for each successful capture event (all six cameras have captured an image).
`internal/`	Contains internal system information such as calibration data, offsets, and trajectories.
`internal/bags/`	Contains bag files with recorded sensor data.
`logs/`	See Logs.
`maps/`	Contains quality map images for the recorded data in different resolutions (see Quality Map).
`wifi/`	See Captured WiFi data.
`dataset.json`	Contains the dataset name entered by the operator, the version layout (dataset identifier), and statistics such as the mapped area and mapping duration.
`sensor_frame.xml`	See Calibration file.
`sensor_frame.xml.sig`	Digital signature of the calibration file
`qualitymap_rec.png`	Quality map for the Recorded dataset
`trolley.cer`	Security certificate for your device.
