Three-dimensional data processing and recognizing method

摘要

The present invention discloses a three-dimensional data processing and recognizing method. It comprises following steps of: scanning and reconstructing objects to be detected so as to obtain three-dimensional data for recognition of the objects to be detected; extracting data matching to features from the three-dimensional data, so that the extracted data constitute an interested target; with respect to the data matching to features, merging and classifying adjacent data points as one group, to form an image of the merged interested target; recognizing a cross section of the interested target; cutting the interested targets by at least one perpendicular plane which passes through a central point of the cross section and is perpendicular to it, in order to obtain a graph; and recognizing shape of the interested targets based on property of the graph.
