基于视频的下颌骨运动轨迹描记

Video-Based Tracing of Mandibular Movement Trajectory

针对现有下颌骨运动轨迹描记设备价格高昂、设备笨重、操作复杂的问题,提出基于视频处理的下颌骨运动轨迹描记方法。使用两个摄像头录制视频,对特制的咬合标志物图像进行处理,采用目标跟踪、坐标转换等算法绘制出下颌骨运动轨迹。基于视频图像处理绘制下颌骨运动轨迹的操作简单,且相应设备轻便。

Aiming at the problems of high price, cumbersome equipment and complicated operation of the existing mandibular trajectory tracing equipment, a video processing-based mandibular trajectory tracing method was proposed. Two cameras are used to record videos, the specially-made occlusal marker images are processed, and algorithms such as target tracking and coordinate transformation are used to draw the mandibular movement trajectory. The operation of drawing mandibular motion trajectory based on video image processing is simple, and the corresponding equipment is light.
