| 摘 要： | 提出了一种新的基于结构光的彩色条纹编码方法完成彩色投影图案的设计.将投影投射到待测量物体表面后,需要对获得的图像进行颜色区分来获得代码信息.基于阈值和HSI空间分色算法,研究了彩色编码中8种颜色的有效区分方法.得到投影图像中条纹的代码信息后,利用摄像机和投影仪的参数计算物体的三维信息.研究了摄像机和投影仪标定以及物体三维信息的计算方法,进而研究了基于样条插值的物体表面三维重建方法.利用提出的方法对石膏模型和人手表面进行三维测量与重建.实验结果表明,所提出的三维重建方法具有较高的重建精度和良好的实时性品质指标.

| Abstract: | A new-type encoding was proposed for colorful stripes based on structured light to design the projection pattern.To obtain the code information of the stripes,a color identification process was carried out on the projected image of a certain object with a corresponding algorithm developed for the eight colors in encoding by combining channel threshold with HSI space.With the stripe code information,the 3-D position of the object could be calculated using the parameters of camera and projector.The ways to ca... |
