Abstract

The invention discloses a method and a device for determining a three-dimensional blood vessel model. The method comprises the following steps: acquiring a plurality of original two-dimensional blood vessel images of a target object and angle information corresponding to each original two-dimensional blood vessel image in the plurality of original two-dimensional blood vessel images; segmenting each original two-dimensional blood vessel image in the plurality of original two-dimensional blood vessel images to obtain a target blood vessel contour of the target object; determining projection position information of at least two light sources based on the angle information corresponding to each original two-dimensional blood vessel image; and controlling the at least two light sources to project linear light beams to the target blood vessel contour according to the projection position information to obtain a blood vessel three-dimensional model corresponding to the target blood vessel contour. According to the invention, a technical problem that a large error exists between a three-dimensional reconstruction image and a real image due to an error caused by an error of an image acquisition device because of direct reading of the shooting angle information of the image during three-dimensional reconstruction of the image in the prior art is solved.

Description

Technical field [0001] The present invention relates to the field of computer auxiliary diagnosis, and in particular, a method of determining a blood vessel three-dimensional model. Background technique [0002] 3D measurement technology, has been widely used in the field of optical correction, spatial angle measurement, some optical measurement series products use near-infrared light wireless detection, track the navigation mark on the instrument, and perform accurate Positioning, this series of products is small and easy to install. At present, research based on image processing technology is based on the direction of computer-aided diagnostic systems and disease analysis, depending on the information of image data, including pixel values, image size, Window Center, Window Width, Offset, Spacing, shooting angles, etc. These parameters are obtained by the own property information of the image, where the shooting angle is primarily applied to the three-dimensional reconstruction ...
