虚拟多结构光自由飞行昆虫运动参数测量系统

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。

A virtual multi-structure light vision system for measuring motion parameters of a free flying insect

Based on analyzing the principles of grating structure light sensors and virtual cameras, a virtual multi-structure light sensor measurement system based on high speed camera and double lasers is proposed, which can overcome motion obstacle introduced by high speed flapping and projection blind area.The free flying insect inducement setting and trigger in terms of small view field of virtual multi-structure light system are proposed.The measurement results of a free flying honey are given.The results show t...
