5.4. 3D digitizing tools

Tip

use document User manual - Point cloud

3D digitalizing tools are used to create precisely defined objects on the point cloud map, by creating relations between the cloud’s points.

Point cloud map

Note

Digitalization tools that are for creating or editing features are available when the active layer is set.

5.4.1. View modes

There are 4 map view modes and 6 camera view modes.

_images/3d_digitalization_viewmodes.png

Map view modes:

  • Bird eye view: User’s point of view is set to free, camera can be moved, rotated zoomed freely on the point cloud map.

  • Panorama spherical view: User’s point of view is placed to the nearest panorama sphere. A panorma image is displayed, the camera can be rotated freely, zoom is limited.

  • Point cloud spherical view: User’s point of view is placed to the nearest panorama sphere, only point cloud points are displayed. Camera can be rotated freely, zoom is limited.

  • Combined spherical view: User’s point of view is placed to the nearest panorama sphere, combined view is used with point clud and panorama image. Camera can be rotated freely, zoom is limited.

User view of the point cloud map is rotated to its predifined views:

  • Left side view

  • Right side view

  • Front side view

  • Back side view

  • Top side view

  • Bottom side view

5.4.2. Settings

Settings of the point cloud map can be set.

Point cloud settings

Actions:

  • Panorama spheres: Show or hides the panorama spheres on the point cloud map.

  • Opacity: Changes the opacity of the point cloud points.

  • Size of points: Changes the size of points on the point cloud map.

  • Point budget [Million]: Changes the number of rendered points on the point cloud map.

  • Colored points clouds (material): Change the coloring of the point cloud map.

  • Brightness: Changes the brightness of the points on the point cloud map.

  • Contrast: Changes the contrast of the points on the point cloud map.

  • Gamma: Changes the gamma of the points on the point cloud map.

5.4.3. Measurement tools

Measurement tools are used to measure lenght, distance, height, area, angle on the point cloud map. Measurement is done between point, (minimum of two) that are set on the point cloud map.

_images/3d_digitalization_measurement_tools.png

Tools:

  • Measurement of distance: Distance is measured between points, multiple points can be set.

  • Measurement of height: Measurement is done between point, distance is measured only vertically.

  • Measurement of distance on horizontal plane: Measurement is done between point, distance is measured only horizontally.

  • Measurement of area: Area is measured between minimum of there points.

  • Measurement of angle: Angle is measured between 3 points.

  • Measurement of angle facing north: Angle is measured between 3 points. When the first point is placed, a second point is placed on the map facing north, and the third point can be placed.

5.4.4. Add new feature

When the add tool is active, drawing a new object is possible on the point cloud map, when a layer is set as active layer. By default the add tool can be activated with the button “e”.

_images/3d_digitalization_add.png

Note

The new object’s type, depends on the active layer’s type. It can be point, line or poligon.

5.4.5. Edit existing feature

When the edit tool is active, objects on the point cloud map are selectable. Selected objects can be edited (add new points, remove, change parameters on form, etc.). By default the edit tool can be activated with button “r”. Edited points can be moved on selected axis. (button “x”)

_images/3d_digitalization_edit.png

Actions:

  • Left click on object (single click): First click selects the object. (point, line, polygon) Other objects cant be selected until the current object is deselected.

  • When the object is selected:

    • Position of the edited object’s point can be changed along x, y, z axes.

    • Add new point to the end of the object. (ctrl + click on line of the object, this action is done by a shortcut)

    • Add new point on the line of the object. (between existing points) (shift click on the line of the object, this action is done by a shortcut)

    • Remove object points: Remove points of the selected object. (buttons “delete” or “d”, this action is done by a shortcut)

    • Active object edit can be deactivated with button “esc”.

  • Layer selection: Selected layer (active layer):

  • When another layer is selected, active drawn object can be saved, removed, or continued.

  • Save parameters: Parameters can be saved through “open form” tool or when the “space” button is pressed.

  • Shortcuts: More information about shortcuts under section “Shortcuts”.

5.4.6. Follow drawing

Follow drawing tool can be activated alongside with the add or edit tool. When the tool is activated and drawing on the point cloud map, camera will be focused on the newly drawn or edit object’s points.

5.4.7. Undo / redo

Undo or redo tool is active when add or edit tool is selected.

_images/3d_digitalization_undoredo.png

Actions:

  • Undo: Undo an action.

  • Redo: Redo an action.

5.4.8. Delete feature

Delete tool is active when an object is selected in the point cloud map.

_images/3d_digitalization_delete.png

Actions:

  • Remove object: Remove selected object.

5.4.9. Copy / paste feature

Tool can be used with the edit tool. When an object is selected on the point cloud map, the tool can be activated. When clicked on the copy tool, the paste tool activates. When clicked on the paste tool the mouse cursor changes to a cross. In this state the copied object can be pasted on the point cloud map.

5.4.10. Join line features

Tool can be used with the edit tool. When an object is selected it changes to color yellow, then another object can be selected by pressing the ctrl button on the keyboard and selecting it on the point cloud map. The second object will change its color to green. Then the join line tool is activated. When used the user will be asked to join the two objects. When it is accepted the first object’s geometry will be changed and the second object will be removed.

5.4.11. Snapping

Snap to vertex tool can be activated or deactivated. When drawing an object, and the pointer is near to another object, it will jump or snap to the other object’s point. Snap to vertex can be used when an object is edited or a new is created.

_images/3d_digitalization_snap.png

Snap tool types:

  • Line: Pointer snaps to the object’s line.

  • Vertex: Pointer snaps to the object’s point.

  • Line and vertex: Pointer snaps to the object’s lines and points.
