Biological compound-eye systems have unique advantages in three-dimensional (3D) positioning based on light energy distribution. A curved compound eye was designed and manufactured to imitate a biological compound eye. To overcome the nonuniform off-axis response and enlarge the aperture of the eyelet, a novel dome light cone was designed. The dome light cone was designed as a conical structure, which consisted of a lot of fiber wires with a diameter of 6 μm. Additionally, based on the proposed biological compound-eye systems, an algorithm was proposed to obtain the 3D position of the object by analyzing the light location and intensity distribution. The effect of the illumination intensity, the position of the target's center, and the non-repeatability were evaluated. The relative standard uncertainty in the 3D position was estimated to be 8.6%. Low uncertainty verified the validity of the 3D localization algorithm.
生物复眼系统在基于光能分布的三维（3D）定位方面具有独特优势。设计并制造了一种曲面复眼以模仿生物复眼。为克服离轴响应不均匀以及扩大微孔孔径的问题，设计了一种新型圆顶光锥。圆顶光锥设计为锥形结构，由许多直径为6μm的光纤丝组成。此外，基于所提出的生物复眼系统，提出了一种通过分析光的位置和强度分布来获取物体3D位置的算法。评估了光照强度、目标中心位置以及不可重复性的影响。估计3D位置的相对标准不确定度为8.6%。低不确定度验证了3D定位算法的有效性。
