Every process started in PointCab is added as a job to Job List. Each job can be edited separately in our Job Editor:
As soon as a layout is laid out, it is visible in overview and under coordinates parameter in Job Editor. In case the finished floor level height is known, it can be defined as a coordinate value under Parameters:
Z coordinates are height parameters of a layout
You find X, Y and Z coordinates of the projection plane in the tab Layout Parameter.
The intersection area defines the width of the selected area – All points, that are part of the yellow highlighted intersection area, are processed by PointCab.
The angle defines the measured angle between the horizontal basis (e. g. X axis) and the created intersection line.
Due to the parameter Direction, you can determine how you look at your object and how it is projected. You can determine, for instance, if you want to look from the bottom up in order to create a ceiling plan.
Use the parameter Align in order to adjust your straight line to the X axis or Y axis.
The function Stretch allows you to extend your straight line at a defined angle.
In menu item Processing you can set up scan positions and resolution of layout :
Each ortho photo created with PointCab consists of single image points that represent each scanned point in your point cloud. Change the image resolution to define the quality of the ortho photo. The higher the resolution, the more detailed is the picture of the point cloud. Ortho photos with a high resolution need more disk space and they often cannot be imported in the same resolution into other systems!
Thus, it is important to find the perfect balance for the analysis. It is usually a better idea to get an overview of the project – at a lower resolution – and then to choose only areas in detail that have to be analyzed.
Apart from X, Y and Z coordinates, a laser scanner determines the reflection properties of a real object. Different materials have different reflection values. By defining the reflectivity, you either get very distinct edges (0%) or you can localize and distinguish differnet materials better (100%).
PointCab allows the use of color information that have been captured by the laser scanner. You can use all color information (100%) or no color information (0%).
For processing, PointCab only uses points within the defined radius around the center of each scanner position (point cloud). This radius is defined in the parameter scan radius. The scan radius should be adjusted to the respective laser scanning project. When the scan radius is too small, “empty” areas are the consequence. Distortion and blurry areas can result from a too large scan radius.
Single scanner positions can be activated or de-activated. If a scanner position is de-activated, the points scanned from that scanner position are not included for processing. PointCab only uses activated scanner positions of the point cloud for processing.
How exact the interface is in respect to chosen CAD system (e.g. if black background is required) can be set up under menu item CAD:
Output settings for CAD
In the tab CAD in the Job Editor, you can adjust the CAD parameters that you have chosen in your CAD system. For instance, you can change the background color or change the export unit from meter into millimeter.
The following image file formats are available in PointCab: PNG – JPG – BMP – TIFF.
The projection defines which coordinates will be saved in the export file. Use the setting “Planar” if you work with 2D systems or 2D CAD software. In this setting, the ortho photo is just created in the XY plane. You find further information about this setting in our tutorial CAD projecton.
The last menu item handles data output settings. For example, a different storage location can be selected or data can be renamed:
Output settings for file
In the tab File, you can adjust the file path and the name of your plan.
The exports indicate the format in which your results will be saved. You can create DWG, DXF and DAE files with PointCab.
