Abstract

The invention provides a straightening method and device for a three-dimensional model of a tubular object and electronic equipment, and the method comprises the steps: obtaining a to-be-straightened original three-dimensional model of the tubular object, and enabling a central line of the original three-dimensional model along the axial direction of a pipeline to comprise a plurality of interception points which are arranged along the axial direction of a pipeline; intercepting the original three-dimensional model through a normal plane of each interception point on the center line to obtain a plurality of annular contours of the original three-dimensional model; conducting coordinate transformation on each annular contour to acquire annular contours arranged on the same straight line, wherein normal vectors of the annular contours arranged on the same straight line are kept consistent, and horizontal axial vectors of the annular contours arranged on the same straight line are kept consistent; and performing three-dimensional modeling on the annular contours arranged on the same straight line to obtain a target three-dimensional model for straightening the tubular object. According to the embodiment of the invention, the integrity of the three-dimensional structure information of the straightened tubular object image can be ensured, and the three-dimensional model of tubular object straightening is obtained.

Description

technical field [0001] The present disclosure relates to the field of image processing, in particular to a method, device and electronic equipment for straightening a three-dimensional model of a tubular object. Background technique [0002] Tubular objects such as blood vessels in biological tissues are usually curved. In medical applications, in order to facilitate medical personnel to clearly observe the anatomical structure of tubular objects such as blood vessels, it is necessary to straighten images of tubular objects such as blood vessels, and then display the straightened images of tubular objects to medical personnel. [0003] Although the existing technology can straighten the tubular object image, the three-dimensional structural information is lost during the straightening process, and the obtained straightened tubular object image describes the two-dimensional information of the tubular object such as blood vessels, and cannot describe the blood vessels, etc. T...
