基于视景仿真技术的虚拟激光投影动态交互方法

Dynamic interaction method of virtual laser projection based on visual simulation technology

虚拟激光投影在动态交互时,易用性差、鲁棒性低都会导致交互方法的交互性能变差,为提高激光投影交互效果,提出基于视景仿真技术的虚拟激光投影动态交互方法。利用VEW方法采集激光投影视频图像,利用加权平均法对采集到的视频图像背景去噪,并基于红绿蓝三原色建立视频的RGB彩色空间模型,对背景去噪后的图像灰度转换后,进行阈值分割;依据预处理结果确定激光投影中心点位置,通过投影的中心点映射,实现投影动态交互;使用视景仿真技术对交互场景图像的交互效果实施增强,提高激光投影的动态交互性能。实验结果表明,运用该方法开展激光投影动态交互时,交互性高、易用性好、鲁棒性高。

Poor ease of use and low robustness of virtual laser projection in dynamic interaction can lead to poor interaction performance of the interaction method.In order to improve the interaction effect of laser projection,a dynamic interaction method of virtual laser projection based on visual simulation technology is proposed.The laser projection video image is collected by VEW method,the background of the collected video image is denoised by weighted average method,and the RGB color space model of the video is established based on the three primary colors of red,green and blue.The threshold segmentation on the grayscale converted image after background denoising is carried out.According to the preprocessing results,the position of the center point of the laser projection is determined,and the dynamic interaction of the projection is realized through the mapping of the center point of the projection.Visual simulation technology is used to enhance the interactive effect of interactive scene images and improve the dynamic interactive performance of laser projection.The experimental results show that the method is highly interactive,easy to use and robust when used for dynamic interaction with laser projection.
