A method for inspecting cargo in an open-topped vehicle comprises obtaining an estimate of a volume of the cargo based on data obtained from a top-observation device 4. The top-observation device observes a top surface 32 of the cargo during a mutual movement of the open-topped vehicle and the top-observation device. Determining an estimate of a mass of the cargo based on the obtained volume estimate and comparing the determined mass estimate with a reference mass to determine whether the cargo is in conformity with the reference mass. An object hidden in high density cargo e.g. metal ore will cause the cargo to have a greater volume. When you use this volume to estimate mass of the cargo you get a greater value than an expected mass. The method may further include estimating height or density of the cargo. The method may obtain inspection data from a side-inspection device 5 using ionizing radiation. Furthermore, the method may trigger an alarm based on when a contraband object such as cigarettes, drugs or weapons are present in the cargo. The top-observation device 4 may comprise of Lidar or millimetre-wave scanner.
