Understanding measurements

icon-measuringStreet Smart allows you to measure in both Cycloramas and the map. To start a measurement, click the measuring icon in the bottom menu bar of one of the viewers. You will get a popup window with the following measurement options:

  • Location
  • Distance
  • Surface
  • Circular Surface (map only)
  • Orthogonal (Cyclorama only)
  • Height (Cyclorama only)

When you are doing a measurement you will get information about your measurement in a small window in the right corner of the viewer, which is the measurement information window.

measuremodeIf you measure in a Cyclorama, more measurement options appear in the Measure mode toolbar above the viewers. Here you can switch between three measurement modes.

measuresmartMeasure Smart mode

icon-depthcycloramasSurface mode is only available for depth Cycloramas (where lidar data is captured in addition to the photographic imagery) and makes it possible to obtain a 3D measurement with one single Cyclorama. To see the lidar data (point cloud) behind a Cyclorama, switch on the 3D depth mode in the measure mode toolbar (switch right). When in Surface mode you will see a surface cursor that follows the contours of the object in the image. This makes it easier to accurately pinpoint the right measurement point.

Smart Click mode uses image matching technology to match the location of your click with the same location in other Cycloramas to obtain a 3D measurement. After you click on a location you will see the image (observation) matches in the measurement information window. When you remove or add an observation, the measure mode of the measurement is changed into forward intersection.

In this mode you can see the viewing lines of an active (opened) point. The color of the line correspond with the triangle in the upper left corner of the image/observation in the measurement panel.

  • In this mode you can manually add a point by adding at least 2 observations for that point.
  • After you click on a location you will see one image/observation added to a point in the measurement window.
  • When you go to another recording you will see that the first point is automatically opened and you can add a new observation to this point.
  • After adding an observation the next point will be opened.
  • A maximum of 3 observation can be added to a point.

In this mode you can see the viewing lines of all points which are measured via Smart Click or Forward intersection. The active (opened) point lines have a color, the color of the line correspond with the triangle in the upper left corner of the image/observation in the measurement panel.

Note: you can switch between the three measurement modes at any time, even within one measurement sequence. However, Surface mode is only available for depth Cycloramas. In case there is no depth Cyclorama available, Street Smart will automatically switch to Smart Click mode.

changemeasurementYou can start a new measurement by selecting the type in the upper right bar. By selecting the arrow down you can start a different measurement type.
