Workflow: Measure a Photogrammetry Point
|
Measure and create a point using photogrammetry data. Following are the basic steps for this workflow. For more detailed instructions, see Measure Points Using Photogrammetry. |

Steps: |
|
Commands: |
|
|
1. |
Use the Import pane to select and import the station and reference photo data into your project. To make a photogrammetry measurement, your project must include two or more stations, each with referenced photo images of the same object. It is important that when you make a photogrammetry measurement, you use observations that provide good geometry. |
|
|
|
2. |
Use the Options dialog to specify various settings that control the behavior of the interface when you are making a photogrammetry measurement. |
|
|
|
3. |
Use the Project Settings dialog to specify intersection and strength of figure tolerances that, if exceeded, cause an out-of-tolerance flag to display with photogrammetry points. Also, specify the maximum length for line-of-sight rays displayed in graphic views. |
|
|
|
4. |
Use the Measure Photo Point command pane to measure and create new photogrammetry points. |
|
|
|
5. |
View photo station data, along with photogrammetry observation and point data, in the Project Explorer, the Properties pane, and the various graphic views. Right-click any photogrammetry point to view the Point Derivation Report, which includes photogrammetry intersection information. Also, view photogrammetry point and observation data in the Photo Point Spreadsheet. |
|
|
|
6. |
If necessary, use the Measure Photo Point command pane to re-measure a photogrammetry observation. |
