X线头影测量为口腔正畸学、正颌外科学等学科进行科学研究及临床工作的重要工具。用于分析的手段已从人工测量分析发展至计算机辅助测量分析。但由于仍需进行人工定点 ,因此仍存在较为费时且精度较差等缺点。本文对 X线头颅片的计算机自动识别进行了研究。以 10名正常的年青恒牙人为研究对象 ,拍摄 X线颅颌侧位定位片。X线片经扫描仪将图象信息输入计算机。经图象处理 ,增强有用的信息从而改善图象质量 ,使其更适合于计算机识别。再通过边缘提取建立目标区域。最后 ,提供了计算机自动识别的颅面硬软组织图象。本实验初步进行了计算机对 X线颅颌侧位片的自动识别研究 ,为以后的深入研究奠定基础。
X-cephalometry for orthodontics, orthognathic surgery and other disciplines for scientific research and clinical work of the important tools. The tools used for analysis have evolved from manual measurement analysis to computer-aided measurement analysis. However, due to the still need to be manually fixed, so there are still more time-consuming and poor accuracy and other shortcomings. In this paper, automatic identification of X-ray cranial computer was studied. Ten normal young permanent people were selected as research subjects, and X-ray cranial jaw lateral positioning films were taken. X-ray film through the scanner image information input to the computer. The image processing, enhance useful information to improve image quality, making it more suitable for computer identification. Then through the edge of the establishment of the target area. Finally, the computer provides automatic identification of craniofacial soft tissue images. In this experiment, the computer automatically identified the X-ray craniofacial flaps automatically and laid the foundation for further research.
