| 摘 要： | 为解决三维扫描仪中图像处理的实时性，提出检测结构结构光条纹 法，本算法把阈值法与可变方向模板法相结合，充分发挥两者的优点，先由主机计算激光条纹度阈值，再结合像素的灰度邻域属性实时确定激光条纹，然后用可变方向模板激光条纹中心，实验表明这种方法具有数据存在量小，实现速度快的特点，而且还有抗白噪声能力和一定的修补断线能力，此外，本方法有利于硬并行实现。

| Abstract: | A method for fast detecting the center of structured light stripe was proposed for the implementation of real time image processing in the three dimensional laser color scanner (3DLCS). The combination of the threshold method and the alterable direction template one made it superior and gave full play to the two methods. The threshold of laser stripe was computed by the host computer and the laser stripe was determined in real time by the neighbor attribute of grey level of pixel. The central line of laser stripe was detected by alterable direction templates. Experiments show that the method possessed the advantages of less data throughput and fast implementation. It can eliminate white noise and repair broken line, and is convenient for the implementation of hardware. |
