R3 Scan File Name Convention
When an R3 scanner acquires a scan, the scan is saved to a file that is named following a systematic scheme that encodes information about it.
The filename of a scan acquired from an R3 scanner has the general form <name>_<speed><data><resolution><levelling><points>_<iteration>.r3s, where each component is defined as follows:
|
<name> |
For defined name scans, this is simply the scan name entered during setup. For survey jobs, this takes the following form:
A scan filename with the prefix |
|
<speed> |
The acquisition speed, expressed as an abbreviation indicating how many times faster the speed is compared to normal speed. The possible values are as follows:
|
|
<data> |
The type of data acquired, as follows:
|
| <resolution> | The point density setting, either 1, 2, 4, 8, or 16. |
| <levelling> |
The type of level correction applied, as follows:
|
| <points> |
Scan point selection, as follows:
|
| <iteration> | This is a numerical suffix to ensure unique filenames for repeat scans, starting at 01. |
r3s
|
The filename suffix used to identify scans from R3 scanners. |
Scans acquired with this naming convention can be registered to the survey reference stations within PointStudio.
A scan file named 20240321 mtcarbo_ss32_ss21_4xC1L-B_01.r3s indicates the following:
-
The scan relates to the survey job named
20240321 mtcarbo, with its location set to survey stationss32, and was backsighted to the survey station namedss21. -
4xmeans the scan was acquired with the Scan Mode set to Rapid. -
Cmeans both range and photo data were acquired. -
1means the Point Density setting was set to 1. -
Lmeans fine levelling was applied. -
-Bmeans the Points setting was set to Best. -
_01means it was the first scan taken with these settings.
A scan file named scan_2xR4U-F_02.r3s indicates the following:
-
The scan was a defined name scan using the name
scan. -
2xmeans the scan was acquired with the Scan Mode set to Fast. -
Rmeans only range data was acquired (no photographic image). -
4means the Point Density setting was set to 4. -
Umeans either coarse levelling was applied, or the scanner was more than 5° off vertical. -
-Fmeans the Points setting was set to First. -
_02means it was the second scan taken with these settings.
Note: If a scan could only be partially completed, for example, because the scanner lost power mid-scan, the suffix _Incomplete will be appended to the filename.
