Point Cab

Deltaチュートリアル

With PointCab Delta Module, you create difference comparisons and difference analyses easily based on your laser scan data.

Create difference comparisons step by step and visualize or record deviations on horizontal and vertical planes, such as floor areas or facades.

  • Analyze facade deformations

    Analyze facade deformations

    In this tutorial, you learn how to analyze the deformation of a facade due to our Delta tool.

    Activate our Delta tool:

    Set the first point of the reference plane in the top view:

    Set the second point of the reference plane:

    The area, which is highlighted in yellow, indicates the point clouds that are analyzed. You can adjust this area viasually or by means of coordinates in the Job Editor:

    Now, you start processing.

    Double-click on the processed job to open the result of the Delta analysis in PointCab. You obtain the same result with the context menu and then with the option Open. You can open the context menu by right-clicking on the processed job.

    By using the context menu, you can display the results by clicking on Show in Folder:

    For each Delta analysis, a PDF protocol as documentation is created:

    In addition to the PDF protocol, the standard output formats, such as DXF, DWG and DAE, are output according to the settings you make and want to use. In this example, we use DWG format:

    You can open the DWG file in AutoCAD, for instance, and position it under your project. Here, the DWG is opened in Autodesk TrueView:

  • Analyze unevenness of the floor

    Analyze unevenness of the floor

    In this tutorial, we show you how you can analyze floor unevenness (or unevenness of the ceiling) due to out Delta tool.

    First, activate our Delta tool:

    For creating a Delta analysis, you should preferably use the front view or side view. Set the first point of the reference plane:

    In order to define the reference plane completely, you need the second point:

    The area, which is highlighted in yellow, indicates the point clouds that are analyzed. You can adjust this area visually or by means of coordinates in the Job Editor:

    Thus, you display the floor unevenness. For a Delta analysis of a ceiling, it is important to align the direction of projection from bottom to top:

    Now, you can start processing:

    Double-click on the processed job to open the result of the Delta analysis in PointCab. You obtain the same result with the context menu and then with the option Open. You can open the context menu by right-clicking on the processed job.

  • Visualize terrian surfaces

    Visualize terrain surfaces

    In this tutorial, you learn how to visualize various terrain surfaces due to our Delta tool.

    For that purpose, activate our Delta tool first:

    Now, you can set the first point of the reference plane visually in the side view:

    Set the second point of the reference plane:

    You can enter the reference height as a coordinate on the right in the Delta Parameters in the Job Editor.

    Now, you can limit or enlarge the yellow highlighted area. The area, which is highlighted in yellow, indicates the area of point clouds that is analyzed. The analysis is made visually by using the single arrows at the reference limits or by entering the coordinates in the Delta Parameters in the Job Editor:

    Then, start processing:

    Double-click on the processed job to open the result of the Delta analysis in PointCab. You obtain the same result with the context menu and then with the option Open. You can open the context menu by right-clicking on the processed job.

  • Delta options

    Delta options

    With our Delta tool, the following options are available in the Job Editor:

    Delta Parameters:

    You can set all settings regarding parameters visually or by entering the coordinates or values.

    You can change the direction of projection easily by clicking on the button Flip.

    Processing:

    In processing options, you can set resolution, colors, individual entries for the generated PDF and much more.

    You can adjust the color map individually.

    Settings regarding the color map:

    To the right of the color map, there is a button with an arrow. With this button, you can open the drop-down menu.

    In this drop-down menu, you can set a discrete flow (hard gradient) or define the single steps of the color change, for instance.

    You can set the gaps between the colors manually by moving the colored arrows. You can adjust the colors individually. By double-clicking on the single colored arrows, you open the color palette:

    You can delete superfluous colored arrows by a left mouse click:

    CAD:

    In the CAD output options, you can change the export unit, background color and file format of the orthophotos.

    File:

    Here, you can select individual memory locations for the PDF protocol and the created orthophotos as well as the output format of the orthophotos. You can output DWG, DXF and DAE.

  • Overview of Delta results

    Overview of Delta results

    In this tutorial, we want to show you a short overview of the results that have been created in PointCab.

    The following results can be created due to PointCab Delta tool:

    1. PDF protocol

    2. Orthophoto in CAD format (DWG, DXF or DAE)

    ——————————————————————————————————————–

    1. PDF protocol

    The PDF protocol is created in the directory Project_Results in the folder Documentation:

    The following content is documented in the PDF protocol:

    1. Cover sheet with the project name, acquisition period and your annotations:

    2. Orthophoto of the analyzed area:

    3. Deviations regarding the plane of projection

    4. Statistic analysis of the results with histogram

    ——————————————————————————————————————————————-

    2. Orthophoto in CAD format (DWG example here)

    The orthophoto is in the directory Project_Results in folder Orthophotos.

    You can import the DWG in your CAD system and continue analysis depending on the needs.
