The Kolor team has been experimenting and developing a new solution to estimate accurately lengths and surfaces in a room from two spherical panoramas. Its code name is StereoPano. It is still in a R&D stage, but we are glad to share some first results.
Basic idea is to shoot two 360×180° panoramas of the same room from two points of view. The second point of view is shot above the first one, so the shooting setup is very easy using the vertical column of a tripod. The only thing to do is to measure the distance from first point of view to second point of view. From these two panoramas, we use the concept of stereoscopy to compute a 3D estimate of the room walls and to extract useful information such as walls edges lengths. Let us explain in further detail the whole process of StereoPano.
You can now export some visual results such as floor plan, room wireframe, or 3D point cloud.
