This is the description of how Trimble Mobile Mapping data needs to be prepared for the Orbit AIM import.
The panorama images are stored in the *.pgr files :
The photo positions are post processed to a *.gps file and then converted into the SHP format :
Orbit | GPS/SHP Attributes | Attribute Type | Data Units | Description |
---|---|---|---|---|
longitude | X | float8 | decimal degrees | Longitude in decimal degrees WGS84 |
latitude | Y | float8 | decimal degrees | Latitude in decimal degrees WGS84 |
Z | Z | float8 | meters | Altitude (orthometric) in meters over the NMM |
pan | heading | float8 | radians | Heading angle or vehicle direction in radians. This angle is defined using the Cartesian coordinates system, which means counter clockwize with a 0 on the positive axis of the X. It is generated by an Inertial Measurement Unit (IMU) or is calclated according to the GPS coordinates |
tilt | Pitch | float8 | decimal degrees | Angle corresponding to the vehicle pitch (front-back) in decimal degrees. Generated by an IMU. |
roll | Roll | float8 | decimal degrees | Angle corresponding to the vehicle roll (left-right) in decimal degrees. Generated by an IMU. |
image | Frame_No | int8 | Unique image ID. In the shape file saved as an integer (INT8) and consequently without leading 0-values. |
The point cloud is the composition of 3 sensors, resulting in 3 *.las files :
