1. A method for inspecting cargoes, comprising: subjecting inspected cargoes to a radiation; acquiring a transmission image of the inspected cargoes from transmitted rays of the radiation; processing the transmission image to acquire an interested region; extracting features from the interested region, and determining cargo information of the inspected cargoes according to the extracted features; and providing a proposed treatment suggestion of the cargoes based on the determined cargo information and at least a part of information in a manifest, wherein the cargo information is spatial arrangement of the cargoes, and the step of extracting features from the interested region comprises extracting description information of the spatial arrangement of the inspected cargoes from the interested region; and the step of providing a proposed treatment suggestion of the cargoes based on the determined cargo information and at least a part of information in a manifest comprises: determining a consistency probability by multiplying the probability of a type of cargoes determined based on real spatial arrangement from the manifest and the conditional probability of the real spatial arrangement based on a predicted one from the transmission image, and in a case that the consistency probability is lower than a predetermined value, judging that the spatial arrangement of the cargoes are inconsistent with the type of the cargoes in the manifest.
