The application discloses a deep vein puncture path generation method and device, the method comprises the following steps: acquiring an ultrasound image of a puncture site; identifying the category of an anatomical target according to the color feature and shape feature of the ultrasound image, and establishing a corresponding feature vector; wherein each feature vector corresponds to an anatomical target; inputting the ultrasound image after the feature vector is established into a preset path model, so that the path model establishes a vein puncture path according to each feature vector, and performs traversal query to output the shortest vein puncture path; wherein the path model establishes a vein puncture path according to each feature vector according to a preset objective function. The technical scheme of the application identifies the anatomical target category in the ultrasound image and outputs the shortest vein puncture path, provides reliable object recognition and path guidance for medical staff, avoids the risk of misjudgment caused by insufficient skills or experience among medical staff, and can improve the accuracy and safety of vein puncture.
