Multidimensional perception identification method and system for goods in carriage

The invention provides a multi-dimensional perception identification method and system for cargoes in a carriage, and relates to the technical field of logistics and cargo detection, and the method comprises the steps: collecting three-dimensional point cloud data and cross-sectional image data containing the information of the cargoes in a container through a laser radar and a camera; segmenting the image into different regions and extracting features of each region; the extracted features are compared with features in a database, and basic information of the object is recognized; comparing differences among different cross-sectional images, acquiring change information of the internal structure of the cargo, comparing the identified image with images in a database, calculating similarity, and judging whether a specific object is contained or not; analyzing the motion trail of the object, judging the motion state, and evaluating the posture of the object; and constructing a three-dimensional model in the com
