The important application of computer imaging technology in the medical field is a necessary auxiliary method for clinical diagnosis and treatment. At present, many people are affected by various factors and have various problems caused by the dental cellular bone. Traditional treatment methods are complex and long, which can cause damage to body tissues. Based on this problem, this paper takes the augmented reality measurement of X-ray dental film as the research object. Based on the in-depth measurement algorithm of the computer image analysis system, two three-dimensional reconstruction methods based on the center of gravity and the matching of the front and side positions are proposed. These two methods only need two X-rays of the front and side of the dental film, the three-dimensional parameters are obtained through calculation and analysis of each spine in the X-ray film, and these parameters are used to fit the dental alveolar bone model. The experimental results prove that the computer-based image analysis system has a great effect on the measurement of X-ray dental film alveolar bone. The positive correlation coefficient reaches 0.87. Compared with the cerebral infarction caused by other methods, the proportion of people with dental film alveolar bone injury is about 15%; after treatment, the functional recovery rate reaches more than 80%. Studies have found that there is a great difference in the age of the population that needs to be treated for dental slices and alveolar bone. The grade of patients is generally under 20 and over 60. This shows that the measurement of X-ray dental film alveolar bone based on computer image analysis system can play an important role in protecting people's oral health.
计算机成像技术在医学领域的重要应用是临床诊断和治疗的必要辅助方法。目前，许多人受到各种因素的影响，存在各种由牙细胞骨引起的问题。传统的治疗方法复杂且耗时较长，可能会对身体组织造成损伤。基于此问题，本文以 X 光牙片的增强现实测量为研究对象。基于计算机图像分析系统的深入测量算法，提出了两种基于重心和前后位置匹配的三维重建方法。这两种方法仅需要牙片的前后两个 X 光片，通过对 X 光片中每个脊柱的计算和分析，获得三维参数，并将这些参数用于拟合牙槽骨模型。实验结果证明，基于计算机的图像分析系统对 X 光牙片牙槽骨的测量有很大的影响。正相关系数达到 0.87。与其他方法引起的脑梗死相比，需要治疗牙片牙槽骨损伤的人群比例约为 15%；治疗后，功能恢复率达到 80%以上。研究发现，需要治疗牙片和牙槽骨的人群年龄存在很大差异，患者的等级一般在 20 岁以下和 60 岁以上。这表明基于计算机图像分析系统的 X 光牙片牙槽骨测量可以在保护人们口腔健康方面发挥重要作用。
