The invention discloses a three-dimensional liver blood vessel segmentation method. The method comprises the following steps: aiming at a target liver image, utilizing a Hesse matrix to carry out preprocessing to obtain an enhanced liver image; inputting the enhanced liver image into a trained segmentation network, and segmenting a liver blood vessel image; and performing segmentation processing on the liver blood vessel image to obtain a blood vessel segmentation result and a liver segmentation result. According to the method, Hesse matrix processing and a segmentation algorithm based on deep learning are organically combined, and the liver segmentation result can be accurately obtained. 本发明公开了一种三维肝脏血管分割方法。该方法包括：针对目标肝脏图像，利用黑塞矩阵进行预处理，获得增强的肝脏图像；将所述增强的肝脏图像输入到经训练的分割网络，分割出肝脏血管图像；对所述肝脏血管图像进行分割处理，获得血管分段和肝脏分段结果。本发明将黑塞矩阵处理和基于深度学习的分割算法进行有机结合，能够准确获得肝脏分段结果。
