复眼具有视场大、灵敏度高、结构紧凑等优点，可用于三维物体检测。在这项工作中，人工复眼系统开发的三维物体检测，包括一层的小透镜和棱镜状光束转向透镜。提出了一种标定方法，该方法利用主动标定图案在多个位置精确地获得入射光线与相关像点之间的对应关系。理论上，在两个位置处的校准图案对于系统校准是足够的，尽管更多的位置将增加结果的精度。点物体的3D位置计算来评估系统，这是通过在最小二乘意义上的多个入射光线的交叉获得。实验结果表明，该系统可以检测到一个目标的角度精度优于1 mrad，证明了所提出的复眼系统的可行性。通过2D扫描设备，该系统可以扩展到3D空间中的一般物体检测。(C)2014年美国光学学会
A compound eye has the advantages of a large field of view, high sensitivity, and compact structure, showing that it can be applicable for 3D object detection. In this work, an artificial compound eye system is developed for 3D object detection, consisting of a layer of lenslets and a prism-like beam-steering lens. A calibration method is developed for this system, with which the correspondences between incident light rays and the relevant image points can be obtained precisely using an active calibration pattern at multiple positions. Theoretically, calibration patterns at two positions are sufficient for system calibration, although more positions will increase the accuracy of the result. 3D positions of point objects are calculated to evaluate the system, which are obtained by the intersection of multiple incident light rays in the least-squares sense. Experimental results show that the system can detect an object with angular accuracy of better than 1 mrad, demonstrating the feasibility of the proposed compound eye system. With a 2D scanning device, the system can be extended for general object detection in 3D space. (C) 2014 Optical Society of America
