摘要: 本发明涉及一种计算机双目视觉的义齿扫描装置及其三维重建方法,包括线结构光视觉采集部分、旋转测量台及其控制部分以及箱体,其中线结构光视觉采集部分中2台高分辨率数字CCD摄像机位于旋转测量台及其控制部分中心侧上方,以线结构光线激光器为中心对称分布;旋转测量台及其控制部分中第1、2附件设于旋转测量台上,旋转测量台通过驱动机构旋转;上述结构安装于箱体中;方法为:将义齿放置在旋转测量台上;线结构光线激光器向义齿投射激光;驱动机构带动旋转测量台连续旋转;两个CCD摄像机摄取图像,传输至外部控制计算机进行处理,得到义齿表面的三维点数据。本发明机械结构和控制方法不需要变速控制,并且对电机的主轴转动没有精度要求,便于操作,扫描精度高。
英文摘要: The invention relates to a computer binocular vision denture scanning device and a three-dimensional reconstruction method thereof. The device comprises a linearly structured light vision collection part, a rotary measuring bed, a control part of the rotary measuring bed, and a box, wherein two high resolution digital charge coupled device (CCD) cameras are positioned on the central sides above the rotary measuring bed and the control part of the rotary measuring bed and symmetrically distributed by taking the linearly structured light laser as the centre in the linearly structured light vision collection part first and second accessories in the rotary measuring bed and the control part of the rotary measuring part are arranged on the rotary measuring bed the rotary measuring bed is driven by a driving mechanism to rotate and the structures are arranged in the box. The method comprises: placing a denture on the rotary measuring bed allowing the linearly structured light laser to project laser on the denture driving the rotary measuring bed to rotate continuously by the driving mechanism and taking pictures by two CCD cameras and transmitting the pictures to an external control computer to process the pictures to obtain three-dimensional data on the denture surface. In the invention, the mechanical structure and the control method need no various speed control, have no requirement on precision of spindle rotation of a motor, and are convenient to operate and high in scanning precision.
