About measurement modes

Real World LiDAR and Camera measurement modes are shown in orange.

Real World measurements measure a point in the real world, captured in the coordinate system of the model you have loaded. The measurements are based on the technology of the device being used. For most devices this is based on visual odometry, calculating distances using camera images and sophisticated algorithms. Some more modern devices include a LiDAR sensor, which allows for much more reliable and accurate measurements. However even with LiDAR, the range tends to be limited to approximately 5 meters (5.5 yards). SiteVision will automatically detect and use the best available Real World measurement method.

To initiate LiDAR or Camera measurements, tap the active measurement app (bottom center of the screen), or tap the cross-hairs.

• The cross-hairs appear as red or white, as follows:

  the cross-hairs are red when...	SiteVision is unable to return a valid distance measurement (e.g. if pointing to the sky, or to some surfaces that it can't easily measure to, such as plain vertical walls with no defining features, or glass / reflective surfaces).
  the cross-hairs are white when...	a valid distance measurement is able to be returned (edges of objects, or patterned surfaces will provide more reliable results for Camera based measurements. LiDAR enabled devices should perform well in most circumstances).

• Both Camera and LiDAR measurements have a limited range of approximately 5 meters (5.5 yards). Beyond these ranges it becomes very difficult to achieve a valid measurement.

Model-based measurements use the Google AR or Apple ARKit functionality to measure to a point directly within the 3D visualization.

To initiate Model measurements, point the cross-hairs at the point in the model you want to measure to, then tap the active measurement app (bottom center of the screen), or tap the cross-hairs.
