Setting the Reconstruction Area

Setting the reconstruction area defines the area of the project on which PhotoMesh should perform the reconstruction steps of the build process, namely: point cloud creation, model creation, model texturing, and project output. The reconstruction area can be defined before building the project (after identifying which areas of the project have sufficient coverage using the coverage map) and also after the build is complete if modifications to the build area are necessary. The same area set for the aerotriangulation can be automatically set for the reconstruction area, or a different area can be defined by either drawing or importing a reconstruction polygon.

Setting a Reconstruction Area Equal to the AT Area

To set a reconstruction area that is the same as the AT area:

§  On the Home tab, in the Area group, click the arrow under Reconstruction Area, and select Same as AT Area.

Drawing a New Reconstruction Area

To draw a reconstruction area polygon:

1.     On the Home tab, in the Area group, click the arrow under Reconstruction Area, and select Redraw Reconstruction Area.

2.     In the 3D Window, draw a reconstruction area polygon around the required area by clicking in the desired locations. You must place at least three points. Right-click to finish the polygon creation.

Importing a Reconstruction Area Polygon

To import a reconstruction area polygon;

1.     On the Home tab, in the Area group, click the arrow under Reconstruction Area, and select Import. The Import Reconstruction Area Polygon Layer dialog is displayed.

2.     Browse to the shapefile or KML with the required polygon, and click Open.

Note:        The first polygon found in the file is used as the reconstruction area polygon.

Editing a Reconstruction Area Polygon

To edit a current reconstruction area polygon:

1.     On the Home tab, in the Area group, click the arrow under Reconstruction Area, and select Edit Reconstruction Area.

2.     In the 3D Window, place the cursor over one of the nodes of the reconstruction area polygon. The node turns blue, and the cursor changes to Move mode .

3.     Click the node and drag it to the required location.

4.     Release the mouse button to set the node at the current location.

5.     Red dots on the polygon’s line segments indicate where a node can be added. Click to add a node, and then drag it to the required location.

6.     Right-click to finish the polygon editing.

Exporting a Reconstruction Area Polygon

To export a reconstruction area polygon:

1.     On the Home tab, in the Area group, click the arrow under Reconstruction Area, and select Export. The Export Reconstruction Area Polygon dialog is displayed.

2.     Browse to the location you want to save to and click Save.

Navigating to the Reconstruction Area

To fly or jump to the reconstruction area:

§  On the Home tab, in the Area group, click the arrow under Reconstruction Area and select Fly to Area/Jump to Area.
