Scoliosis (scoliosis), also known as scoliosis, refers to a three-dimensional deformity of the spine in which the physiological curvature of the sagittal plane changes, the coronal plane flexes laterally, and the vertebral body rotates in cross-section. The international society of scoliosis research (Scoliosis Research Society, SRS) proposes that the Cobb method is adopted to measure the full-spine coronal plane X-ray under the standing position of a human body, and if the Cobb angle is more than or equal to 10 degrees, the diagnosis of scoliosis is confirmed. Wherein, the Cobb angle is less than 20 degrees and is defined as slight scoliosis, so that the rehabilitation effect is better. 20 ° < Cobb angle <45 ° is defined as moderate scoliosis; cobb angle >45 ° is defined as a heavy scoliosis.

However, the prior art has at least the following problems: 1. aiming at sagittal plane spine images, related spine measurement parameters are generally required to be manually measured by tools such as a ruler, and the like, so that the manual measurement is complex in operation and easy to have larger errors, and not only brings great work trouble to doctors, but also is not beneficial to follow-up accurate diagnosis and treatment judgment of patients; 2. after the related index of the spine measurement parameter is clinically determined, drawing cutting is generally utilized or the post-operation spine morphology after the osteotomy is simulated is directly drawn on the drawing, and the related index of the post-operation spine measurement parameter is obtained so as to determine whether the life requirement of a patient can be met after the orthopedic operation is implemented; however, the disassembly operation is more, the workload is large, the efficiency is low, the time consumption is long, and the mistakes are easy to occur.
