Prepare MM Data 3D Laser Mapping
After capturing data with the 3DLM StreetMapper or V-Mapper, use the standard 3DLM tool SMProcess to process and prepare the data for importing into Orbit.
It is strongly recommend to read first following documentation :
Trajectory
- File : one ascii .pos text file
- Crs : default coordinate system is WGS84 geographic (EPSG 4326). To define a local projected crs contact (support at 3dlasermapping dot com)
- Data-structure : Flat ascii text file, tab separated, no column headers, with columns : timestamp, latitude, longitude, height, roll, pitch, heading, Y-accuracy, X-accuracy, Z-accuracy, pitch-accuracy, roll-accuracy, heading-accuracy

Images
- Files : *.jpg files, each panorama is one jpg image file.
- Naming : exactly as described in photo position file (see above, last column)
Export from SMProcess
- Open your project in SMProcess
- Add the ladybug streams to the project that need processing
- Go to ‘Process Image Data’
- Select the ladybug stream to process
- Select the ‘Create Panoramic Images’ option
- Click the ‘Add To Process Images’ button
- Click on the ‘Event Options’ tab at the bottom
- Select the ‘Create Orbit Photo List’ option
- Click ‘Add To Process Events’ to create the Orbit Photo List
- This file will be used in Orbit to import the panoramic image positions
Pointcloud
- File : one or multiple .las files
- Crs : default coordinate system is WGS84 geocentric / ECEF (EPSG 4978). To define a local projected crs contact (support at 3dlasermapping dot com)
- Data-structure : default Las structure (v1.2)
Export from SMProcess
- Open your project in SMProcess
- Add the lidar data to the project
- Go to ‘Create Point Cloud’
- Select the lidar file to process
- Select the options to process with and the coordinate system to GeoReference it in
- Click ‘Add To Process List’ to start processing the point cloud
