Abstract
The invention discloses a medical image-based auricle projection area measurement method and system, and belongs to the technical field of forensic medicine. According to the method, a head CT image sequence is subjected to three-dimensional reconstruction through an improved Marking Cubes algorithm to form a high-precision head three-dimensional model, an auricle region is further extracted through fine segmentation, auricle projection areas are automatically measured at all visual angles through a dynamic angle iterative algorithm, and finally the maximum projection area value is determined. The problems that traditional manual measurement is low in precision and poor in efficiency, and the precision is affected due to the fact that modeling holes are prone to occurring in handheld three-dimensional scanning equipment are solved. The method can be applied to forensic medicine auricle defect quantitative evaluation, and a high-precision and objective basis is provided for judicial expertise.
