Abstract
In some examples, it is disclosed a computer-implemented method for inspecting cargo in an open-topped vehicle, including: obtaining an estimate of a volume of the cargo in the open-topped vehicle, based on data obtained from a top-observation device, the top-observation device being configured to observe a top surface of the cargo in the open-topped vehicle during a mutual movement of the open-topped vehicle and the top-observation device; determining an estimate of a mass of the cargo in the open-topped vehicle, based on the obtained volume estimate; comparing the determined mass estimate with a reference mass associated with the cargo in the open-topped vehicle; and determining whether the cargo in the open-topped vehicle is in conformity with the reference mass, based on the comparing.

A computer-implemented method for inspecting cargo in an open-topped vehicle, comprising:
- 1) Obtaining data from a top-observation device, the top-observation device being configured to observe a top surface of the cargo in the open-topped vehicle during a mutual movement of the open-topped vehicle and the top-observation device;
- 2) determining an estimate of at least one characteristic of the cargo in the open-topped vehicle, based on the obtained data,
- wherein determining the estimate of the at least one characteristic of the cargo comprises determining an estimate of a volume of the cargo in the open-topped vehicle, comprising at least one of:
- determining the volume estimate using data received from the top-observation device, and
- receiving the volume estimate from the top-observation device, and
- determining a mass estimate, comprising:
- obtaining inspection data measured by a side-inspection device configured to inspect the cargo using ionizing radiation during a mutual movement of the open-topped vehicle and the side-inspection device, the inspection data being measured after transmission of the ionizing radiation through an upper part of the vehicle, including an upper part of the cargo,
- obtaining first mass equivalence data associated with the irradiated upper part of the vehicle not including the cargo, the first mass equivalence data being with respect to a reference material, based on the obtained inspection data,
- obtaining second mass equivalence data associated with the irradiated upper part of the vehicle, including the upper part of the cargo, the second mass equivalence data being with respect to the reference material, based on the obtained inspection data,
- obtaining third mass equivalence data associated with the irradiated upper part of the cargo, based on the obtained first mass equivalence data and the obtained second mass equivalence data,
- obtaining one or more estimates of profiles of a top surface of the cargo in the open-topped vehicle, based on the data obtained from the top-observation device,
- determining the mass of the upper part to the cargo, based on the obtained third mass equivalence data and the obtained one or more estimates of profiles,
- determining the mass estimate of the cargo, based on the determined mass of the upper part to the cargo and the determined volume estimate for the cargo in the open-topped vehicle
- wherein determining the volume estimate comprises:
- obtaining estimates of profiles of the top surface of the cargo in the open-topped vehicle, based on the data obtained from the top-observation device;
- obtaining an estimate of a height of the cargo under the top surface of the cargo in the open-topped vehicle;
- determining the volume estimate, based on the obtained profile estimates and the obtained height estimate;
- 3) comparing the determined characteristic estimate with a reference characteristic associated with the cargo in the open-topped vehicle;
- and
- 4) determining whether the cargo in the open-topped vehicle is in conformity with the reference characteristic, based on the comparing.

- wherein the top-observation device comprises at least one of one or more Lidar scanners and one or more millimetre-wave scanners,
- the top-observation device being mounted fixed with respect to the ground, the open-topped vehicle being mobile with respect to the ground,
- 2) determining an estimate of at least one characteristic of the cargo in the open-topped vehicle, based on the obtained data,
- 3) comparing the determined characteristic estimate with a reference characteristic associated with the cargo in the open-topped vehicle;
- and
- 4) determining whether the cargo in the open-topped vehicle is in conformity with the reference characteristic, based on the comparing.
