Point Cloud

 

POINT CLOUD TAB

Project

Import Cyclone (Configure Database) = Scan data must be configured in cyclone prior to importing into IMS. IMS with the Point Cloud extension provides licenses to import various scanner data into Cyclone so that it can be imported into IMS. Register 360 Projects are exported then imported into Cyclone so that IMS can operate over the top of Cyclone allowing you to draw on the point cloud data.

Import JetStream = Jetstream is a data sharing software tool that allows for extremely high speed transfers of complex point cloud data. Files are managed in a JetStream vault. Regeneration time for point cloud data in IMS is generally eliminated when JetStream data is being viewed in IMS.

Import HeXML = HeXML is a LiDAR database maintained by Leica. Subscription to the database is available allowing for importing images into IMS that can accurately be measured from.

Purge = Eliminate point cloud data from IMS drawing.

RENDERING

Regen Cloud = Force IMS / Cyclone to regenerate the displayed point cloud data. This is used frequently when zooming into a detailed area to better view details for drawing or prior to doing screen captures or printing.

Toggle Visibility = Hide the entire point cloud. Facilitates working with just line work or selecting lines when point node grip is on.

Colors from Scanner = Choose from three sub menus on what color the point cloud data will be displayed. Select the best to visualize the subject of your image or ability to select data points while drawing.

Colors from Scanner will provide RGB color data that has been applied to each data point from photographs taken by the scanner. Not all point clouds will have color data.

Intensity Mapping is the amount of returning light captured by the scanner and is used to create a Hue Intensity Map where colors displayed are based on how much light was reflected back from the surface.

Greyscale is produced from the Hue Intensity Map values. Rather than displaying highly reflective surfaces in an orange yellow red hue the map converts to white - grey - black.

Point Size = Each point in the point cloud can be reduced or enlarged. Thin point clouds can display better when the point diameter is enlarged.

Point Density = Altering the number of points displayed will improve the displayed image of the point cloud. Displaying the full cloud can cause a slower movement and regeneration of the displayed points and is dependent on computer used and video card settings. Many users will navigate to the area of interest using a low density setting then set to high for detailed selection work.

Preferences = Point loading can be controlled in the settings. Displaying too many points can cause computers with low RAM to crash.

SNAPPING

Toggle Point Snapping = Turn off snap

SmartPick Viewport = Very important zoom tool allows node snap to select the highest edge point in the area selected keep lines level.

ORIENTATION

Floor+Wall = Six tools will set the drawing UCS plane to match a wall, wall+wall or floor+wall. CAD requires the drawing plane be set to the surface being drawn otherwise the line work will not lay flat on that surface. Tool is frequently used to change your working surface as you draw 3D objects.

Plan View / Elevation View = Rotate UCS between top down (plan) and side (elevation) views. Used to swap quickly when drawing 3D objects.

Align View to Workplane = Use this command to update the modelspace view to be straight to the surface being drawn on.

Reset View to World = Will return UCS to the World view.

Coordinate Systems... = Create new UCS views or select views from World, Top, Right, Left etc UCS views.

Points on Grid

CLIPPING

Clip Outside / Inside Rectangle = Prior to selecting fence, if you are going to cut inside or outside of a fence (Rectangle, Polygonal, Circle)

Limit Box = Create a box where only objects in the selected area can be worked with.

Slice X Axis = Create slices of a point cloud in the x,y,z axis. You can push a slice thickness forward or backwards.

Section Right = Cut in the x,y,z planes to remove a roof, wall or floor.

Clipping Manager = From the clipping manager turn on / off the view for each clip, limit box, slice and section cut.

Reset Clipping = Rapidly clear the modelspace view of any selected clippings.

Clipping Scheme =

TruSpace

Open TruSpace = TruSpace allows the viewing of a single scan position from the perspective of the scanner.

Show/Hide TruSpace =

Sync Toggles...

Perspective Camera Off

Open KeyPlan

ScanWorld Explorer

Tools

Bullet-Path Reconstruction

QA Protocol = IMS offers the creation of a measurement validation of NIST twin target poles captured in the scan data and will return the value between the measurement taken from the scan data and the NIST validated measurement.
