The invention relates to a dynamic three-dimensional reconstruction method of single-arm X-ray angiogram maps, which belongs to the field of the intersection of digital image processing and medical imaging and aims to meet the requirements of the auxiliary detection and surgical navigation of cardiovascular diseases in clinical medicine. The invention provides a concept of 'dynamic vessel three-dimensional reconstruction', so that the angiogram maps of double visual angles at different moments are compensated for respiratory movement and cardiac movement. The dynamic three-dimensional reconstruction method can obtain the high three-dimensional reconstruction accuracy of coronary artery vessels, solve the problem that the automatic and reliable three-dimensional reconstruction is performedby multi-visual angle angiography maps with different time phases, assist in the detection and surgical navigation of the cardiovascular diseases effectively and meet the clinical requirement.
