The below animation shows an intensity and colorized point cloud of a two mile stretch of levee along the east bank of the Mississippi River outside Baton Rouge. Areas not colorized do not appear in the photographs taken by the on-board cameras.
Some of the challenges we face in colorizing point clouds include:
- Changes in sun angle during collection
- Orientation of the vehicle with respect to the sun (vehicle shadow in images)
- Saturation of the upper portions of tree canopies
- Vehicles and other extraneous objects in the images
Again, project planning comes into the "picture." If a colorized point cloud of a roadway corridor is required, it would prove more wise to perform two shorter collections during off-peak hours (perhaps a Saturday and Sunday morning) to improve the final product.
What software Did you us for this animation?
ReplyDeleteWe utilized Pointools for this animation.
ReplyDeletegreat to hear, thanks for using our software. is Pointools your first choice for point cloud animations?
