画像の RGB 値を ArcGIS Pro のオーバーレイ LAS ポイントに割り当てる

サマリー

Applying colors and near-infrared values from imagery to LAS points provides an immersive, photorealistic display of the points. This article describes the steps to assign the RGB values from imagery to the overlaying LAS points using the Colorize LAS tool in ArcGIS Pro.

手順

Note:
To run the Colorize LAS tool, the imagery must have RGB information to assign to the LAS points.

1. In ArcGIS Pro, add the imagery and overlaying LAS dataset to a project.
2. In the Geoprocessing pane, search for and open the Colorize LAS tool.
   1. For Input LAS Dataset, select the LAS dataset to colorize.
   2. For Input Image, select the imagery to assign colors to the LAS points.
   3. Set the Band Assignment parameter if it does not auto-populate.
   4. For Target Folder, set a folder to locate the colorized LAS dataset.
   5. For Output LAS Dataset, set a name for the output colorized LAS dataset.
   6. Click Run. The colorized LAS dataset is added to the map.

3. In the Contents pane, right-click the output LAS dataset layer, and click Symbology.
4. In the Symbology pane, under Points, ensure the Draw using check box is checked, and select RGB in the drop-down list. The LAS points are assigned with colors from the imagery.
