Using Aurora Envision to extract roof slopes, edge lengths and obstruction and tree heights requires you to navigate between 2D and street view.
Measuring object height
- In 2D mode, click on Street View in the top right.
- On the right of your screen click on the Measurements icon.
- Within the Measurements icon, click on 3D Measurement - this measures the distance between two points in three-dimensional space.
- Click on 2 points in your 2D image.
- In street-view drag the points that appear to the base and the top of the 3D object you are looking to measure.
- Go back to your 2D view, move the points close to each other such that the angle shows as being close to 90 degrees.
To ensure that your measurements are accurate, you will have to calibrate your camera position. To calibrate the camera position, Aurora needs at least 3 distinct points in the design.
Calibrating your camera position
- Repeat steps #4 and #5 for an additional set of points to your roof drawing - some place away from the first object you were measuring. We recommend that you add the points along an edge of the building, or some other location where it is easy to make sure the 2D and 3D image matches.
You are adding these points to help Aurora figure out where the camera was when it took the street view image.
- After you have added the additional points, click on Measurements icon, then click on Calibrate. Your measurements should automatically update with new, more accurate values.
