提出了基于单摄像机和双结构光投射器的虚拟多结构光视觉测量系统测量高扇翅频昆虫飞行运动参数。首先分析了光栅型结构光视觉的测量原理以及虚拟多结构光传感器的工作原理,针对昆虫的运动遮挡提出了多角度观测的设计思想,在此基础上建立了基于单摄像机和双结构光的虚拟多结构光视觉测量系统。实验结果表明,该测量系统可以实现固定飞行昆虫双侧翅膀运动参数的测量;该系统不仅降低了系统成本,而且避免了多摄像机同步驱动的复杂性。
A virtual multi-structured optical vision measurement system based on single camera and double-structure light projector is proposed to measure the flight parameters of high-winged insects. Firstly, the measurement principle of the grating-type structured light vision and the working principle of the virtual multi-structure optical sensor are analyzed. A multi-angle observation design idea is proposed for insect motion occlusion. Based on this, a virtual camera based on single camera and double structure light Multi-structured optical vision measurement system. The experimental results show that the measurement system can measure the movement parameters of bilateral wings of fixed flight insects. The system not only reduces the system cost, but also avoids the complexity of multi-camera synchronous driving.
