Abstract
Method for calculating a linearization curve for determining the fill level in a container from a filling height, said method comprising the following steps: acquiring three-dimensional data of the container with a mobile end device, having at least one optical camera, a depth sensor and a motion detector, establishing a three-dimensional model of the container, and calculating the linearization curve from the three-dimensional model for determining a fill level from a measured filling height.
