Prepare Navvis M3 Data

This page describes the original Navvis M3 Trolley-V1 indoor mobile mapping resources for Orbit import.

Use the corresponding Orbit Import Template to import the described original data.
It is recommend to read first Concepts of Mobile Mapping and UAS data in Orbit.

• Image type : Equirectangular panoramas.
• Image resolution : 8192×4096 pixels.
• File format : Each image is one *.jpg file.
• File name : Exactly as in image positions file, see below.
• Folder structure : all files in one folder.

• File format : One ascii *.csv or *.txt file.
• File structure Rows : Each image is one record.
• File structure Columns : Semicolon separated (char59), headers, with exact order as the example below.
• Value “filename” : File name as on disk, with file extension.
• Value of “pano_pos” coordinates : Projected coordinates, local height, decimal notation, no thousands separator.

• File format : One or more supported point cloud files.
• Value of Coordinates : Same references as Panorama Photo Positions, see above.

By default, the NavVis software exports the pointclouds as .ply files. To transform a pointcloud in.ply format to an Orbit supported format, widely available free third party software can be used.
