The load volume measurement system measures the load volume of truck loads on flatbed loading areas or the remaining loading volume of dump trucks in a single pass and without the need for the vehicle to come to a stop. Having precise data on load volumes is especially important for loads with an unknown moisture content, for example, to determine the dry weight. The vehicle is scanned up to 100 times per second using eye-safe 2D LiDAR sensors. The 3D model created from the collected measurement data serves as the basis for calculating the load volume. The system reliably identifies irrelevant vehicle parts and fasteners and excludes them automatically.
