The embodiment of the invention provides a blood vessel curvature evaluation method and system based on a local-overall ratio, and belongs to the technical field of image processing. The method comprises the following steps: collecting image information containing blood vessels, and splitting the blood vessels into a plurality of local blood vessels based on a blood vessel path fitting result; the local blood vessel curvature of each local blood vessel is calculated, and the bending condition of the current blood vessel is evaluated based on the blood vessel path fitting result; obtaining the curvature of the current blood vessel based on the local blood vessel curvatures of all the local blood vessels and the tortuosity of the current blood vessel, and calculating the tortuosity of the current blood vessel based on the tortuosity of the current blood vessel; and performing current curvature evaluation based on the curvature of the current blood vessel and the tortuosity of the current blood vessel.
