摘要
提出一个基于红外视觉的多点触摸检测的图像处理算法.首先对红外图像进行预处理,采用提出的改进的带系数的OTSYU法来进行图像分割,获取目标区域.然后对递归填充的多触点算法进行改进,提出使用此采用扫描区域填充法来实现多触点检测.实验表明,此算法能够准确地实现特征点的检测和识别并且算法实时性效果极好.
In this paper, primarily, the infrared images captured by FTIR system are pre-processed. The image of foreground and background are segmented by OTSU＇s method with a coefficient. Scan area filling method is adopted to recognize the multi-contact area. The result shows that the performance of the system fully meets the requirements of real time and accuracy.
