ENVIColorPointCloudTask

ENVIColorPointCloudTask

This task colorizes a point cloud using raster data. Each point of the point cloud receives the RGB value of the raster pixel that has the same location.

Example


; Start the application
e = ENVI()
 
; Select input data
inputPointCloudURI = Filepath('Avon.laz', $
Subdir=['data','lidar'], Root_Dir=e.Root_Dir)
inputPointCloud = e.OpenPointCloud(inputPointCloudURI)
 
inputRasterURI = Filepath('Avon.dat', $
  Subdir=['data'], Root_Dir=e.Root_Dir)
inputRaster = e.OpenRaster(inputRasterURI)
 
; Get the task from the catalog of ENVITasks
Task = ENVITask('ColorPointCloud')
 
; Define the inputs of the task
Task.INPUT_POINTCLOUD = inputPointCloud
Task.INPUT_RASTER = inputRaster
Task.OUTPUT_POINTCLOUD_URI = e.GetTemporaryFilename('las')
 
; Run the task
Task.Execute
 
; Only one dataset open at a time
inputPointCloud.Close
 
; Display the point clouds in the ENVI LiDAR viewer
pointCloud = e.OpenPointCloud(Task.OUTPUT_POINTCLOUD_URI)
Viewer = ENVIPointCloudViewer()
Viewer.Display, pointCloud

Syntax


Result = ENVITask('ColorPointCloud')

Input properties (Set, Get): INPUT_POINTCLOUD, INPUT_RASTER, KEEP_NON_OVERLAPPING_POINTS, OUTPUT_POINTCLOUD_URI, POINT_COLOR_OUTSIDE_RASTER

Output properties (Get only): OUTPUT_POINTCLOUD

Properties marked as "Set" are those that you can set to specific values. You can also retrieve their current values any time. Properties marked as "Get" are those whose values you can retrieve but not set.

TAGS

This task also contains the following properties:

INPUT_POINTCLOUD (required)

Specify a point cloud to colorize.

INPUT_RASTER (required)

Specify the raster to use to color the point cloud. The input raster must have spatial reference information.

KEEP_NON_OVERLAPPING_POINTS (required)

Set this property to false to remove points outside the raster footprint when creating the output point cloud. If set to true, the points are colored according to the POINT_COLOR_OUTSIDE_RASTER parameter. The default is true.

OUTPUT_POINTCLOUD

This is a reference to the output point cloud.

OUTPUT_POINTCLOUD_URI (optional)

Specify the URI for the output of the colored point cloud file.

POINT_COLOR_OUTSIDE_RASTER (optional)

Specify the color of the points that are outside of the raster footprint as a byte array of dimension 3 describing the intensity of each R, G and B channels. The default is [0, 0, 0] (black).
