在分析结构光视觉测量原理和虚拟摄像机原理的基础上,针对高扇翅频昆虫的运动遮挡和激光投射器的投射盲区,提出了基于单摄像机和双激光投射器的虚拟多结构光视觉传感器测量系统;针对昆虫特性和虚拟多结构光传感器有效视场范围小的特点,设计了昆虫自由飞行引导和触发装置,实现了高扇翅频昆虫双侧翅膀运动参数的测量,并对实际昆虫运动参数测量结果进行了分析。实验结果表明,该系统不仅降低了系统成本,而且减少了多摄像机同步驱动的复杂性。
Based on the analysis of the theory of structured light measurement and the principle of virtual camera, this paper proposes a virtual multi-structure optical vision sensor based on single camera and dual laser projector to detect the movement occlusion of high-sector insects and the shadowing area of laser projector. System. In view of the characteristics of insects and the small effective field of virtual multi-structure optical sensors, a free flight guidance and triggering device for insects was designed and the measurement of bilateral wing movement parameters of the high fan-winged insects was carried out. The actual insect movement parameters The measurement results were analyzed. Experimental results show that the system not only reduces system cost, but also reduces the complexity of multi-camera synchronous drive.
