Outdoor scene three-dimensional color point cloud classification method

The invention relates to the technical field of three-dimensional point cloud data processing and three-dimensional scene reconstruction, in particular to an outdoor scene three-dimensional color point cloud classification method comprising the following steps: (1) obtaining outdoor scene three-dimensional color point cloud data, (2) constructing an outdoor scene three-dimensional color The pointcloud data training set, (3) constructing conditional random field classifiers in point cloud and image modalities, (4) performing learning training and classification inference in the point cloud modality, (5) performing learning training and classification inference in the image modality; (6) giving a final classification results, and (7) continuously updating collaborative learning. The outdoorscene three-dimensional color point cloud classification method has the advantages that first single-modal learning is extends to be multi-modal learning, interactive learning between modalities is utilized to construct a mul
