摘要
昆虫复眼由成百上千个小眼组成,具有大视范围内的快速识别能力.本文仿昆虫复眼的快速定位特性,提出一种基于小眼视场交汇空间分区的动目标位置快速估计法.根据探测器阵列组合与空间视野范围的对应关系建立参量方程,参量为检测到动目标时探测器阵列的组合方式;模拟探测器阵列与运动目标,验证定位算法的快速估计能力;最后通过阈值比较获得检测到目标的探测器组合方式,求解参量方程实现目标定位.对定位计算结果与实际模拟距离进行比较,结果表明该算法能够实现不同大小目标在不同运动轨迹下的位置估计.
Compound eye consistis of thousands of ommaditia, which insures the ability of fast detection and location on obstacles and predators. Inspired of compound eye, a method of fast location estimation was proposed. Firstly, a parametric equation between space and detectors field of view was established including unknown parameters, which can be gotten from the array of deteeters detected moving targets; secondly, detectors in line array were used to get moving objects signals by simulation; finally, analys the signal data with threshold to form the array of detectors, which was used to solve parametric equation and achieve positioning. Compared with the result betwen actual distance and the calculated, the results show the method can achieve the target location estimation of different sizes in different trajectories in time.
