Claim 1:
2. The method of claim 1, wherein the step of regressing of 3D heat maps corresponding to the positions of the key points of the vertebra mass center based on the regression results of the heat maps of the key points and the pre-processed vertebra CT image data comprising:
by combining a U shaped convolutional neural network and space information extraction network, serving the pre-processed vertebra CT image data as an input, serving the position of the key points of the vertebra center mass as the labels, for confirming heat maps corresponding to 6 target positions in the regression result of the 25 heat maps of the key points; the heat maps corresponding to the 6 target positions include 3D heat maps corresponding to a first block of a cervical vertebra, a last block of the cervical vertebra, a first block of a lumbar vertebra, a last block of the lumbar vertebra, a first block of a thoracic vertebra, and a last block of the thoracic vertebra.
