Construction method and device of three-dimensional blood vessel model, equipment and storage medium

The invention discloses a three-dimensional blood vessel model construction method and device, equipment and a storage medium, and belongs to the technical field of computers. The method comprises the following steps: acquiring a first initial blood vessel center line and a second initial blood vessel center line; taking the first initial blood vessel center line as a first target blood vessel center line, and taking a projection point of a blood vessel key point on the first target blood vessel center line in a three-dimensional space as a target space point; determining a third transformation matrix based on a fourth projection point of the target space point on the second blood vessel image and a blood vessel key point on the second initial blood vessel center line; transforming the second initial blood vessel center line based on a third transformation matrix to obtain a second target blood vessel center line; acquiring a three-dimensional blood vessel center line passing through the target space point ba
