The 3D measurement tools are available for both Free and Pro projects. Only the owner of the project can apply the measurement tools to his/her project.
Go to the project page of one of your projects.
Click the Studio tab on the left sidebar.
Click the button Measurement Tools on the tool bar to activate the measurement tools
Left click to add measurement point(s) and draw a polyline. Right click to end the measurement. If the polyline is closed, the area of the enclosed polygon will be computed.
Here is a video tutorial:
Distance: the distance between the two endpoints of a line segment in 3D, or the sum of the distances of all connected segments.
Horizontal Distance: the distance between the two endpoints of a projected line segment on the ground plane from the 3D line segment, or the sum of the projected distances of all connected segments.
Elevation: the vertical distance between the highest and the lowest points of all segment endpoints.
Area: the area measurement enclosed by the 3D polygon in space.
Projected Area: the 2D area measurement by projecting the 3D polygon on to the ground plane.
Volume, Cut and Fill
Before moving on, we need to first understand two concepts, namely Base Polygon and Reference Plane.
However, please keep in mind that this does not mean that you should click “Ortho View” when you draw the base polygon. Orthoview is a 2D orthophoto of your 3D model. This means, if you draw a polygon in a 2D picture, the position of the polygon may not be so accurate when the picture is turned into a 3D model.
1) Cut: As shown above, Cut refers to the positive 3D volume above the base polygon (or “reference plane” when the base polygon is oblique). Suppose you need to cut the height of the current model to the elevation of the base polygon, this is the volume you need to cut from the current model.
2) Fill: It refers to the negative 3D volume below the base polygon (or “reference plane” when the base polygon is oblique). Suppose you need to fill all the parts of the model below the area of base polygon, this is the volume you need to fill in the current model.
3) Volume: The total 3D volume enclosed by the 3D surface and a base polygon (or “reference plane” when the base polygon is oblique). This volume is the sum of the Cut and the Fill where the Cut is positive measurement above the base polygon while the Fill is negative, below the base polygon.
There are two possible reasons:
The project is not reconstructed successfully.
The images you upload do not contain GPS information. Or, the GPS information in the images is not precise enough to allow our engine to extract the correct dimension of the 3D models.
Yes. Click the Share button on the dropdown field of Measurement Result, and share the 3D model with your colleagues and friends.
In the pop-up dialogue, there're generally four ways to share your measurements with others:
The 3D model that you can embed in your homepage will be like this.
The results of these tools are provided as they are. The accuracy of the measurement highly depends on the quality of the 3D reconstruction and the GPS recorded in the input images. Please DO survey ground control points to validate the accuracy before you apply the results to your project.
