基于MFC的航海视景系统实时碰撞检测技术

针对在航海视景帧流速较大、计算量增加时,会使虚拟场景中人机交互响应时间长,导致航海视景系统实时碰撞检测技术耗时长、准确率低的问题,设计一种基于MFC的航海视景系统实时碰撞检测技术。引入Sobel边缘算子精准提取发生畸变的边缘像素,得到单像素级别的图像边缘,建立基于MFC的航海视景系统框架,通过纹理映射消减航海视景复杂度,最后使用八叉树剖分技术完成实时碰撞检测。实验结果表明,在帧流速小于20帧/秒时响应时间无差别,随着帧流速的增加,设计的检测技术响应时间明显小于传统技术,且实时碰撞检测准确率较高。

Real-time collision detection technology of navigation visual system based on MFC

Regarding the problem that when the frame flow rate of the navigation scene is large and the amount of calculation increases,the human-computer interaction response time in the virtual scene would be long,resulting in the long time-consuming and low accuracy of the real-time collision detection technology of the navigation scene system.Therefore,a design based on MFC real-time collision detection technology of the navigation visual system is proposed.The Sobel edge operator is introduced to accurately extract the distorted edge pixels to obtain single-pixel-level image edges,and establish a MFC-based navigational vision system framework,which reduces the complexity of the navigational vision through texture mapping,and finally the octree division technology is used to complete real-time collision detection.Experiment results show that there is no difference in response time when the frame flow rate is less than 20 frames/s.As the frame flow rate increases,the designed detection technology has a significantly shorter response time than the traditional technology,and the real-time collision detection accuracy is higher.
