摘　　要：提出了一种基于多像素光子计数器的三维成像方法。利用高重频脉冲激光作为光源,振镜作为扫描装置,多像素光子计数器作为探测器,可编程程门控阵列作为总控制器,设计了一种基于多像素光子计数器的三维成像系统,通过光度立体算法实现对物体的三维成像。实验研究结果表明:所提方法可以实现弱光条件下对复杂物体的快速高分辨率三维成像,成像分辨率为512像素×512像素,数据采集时间小于6.7 s。所提成像方法可以应用弱光条件下的远距离快速三维成像,并具有往远距离抗湍流成像,非直视成像的潜力。A three-dimensional imaging scheme based on multi-pixel photon counter(MPPC)is proposed.A three-dimensional imaging system based on multi-pixel photon counter is designed by using high-repetition-rate pulse laser as the light source,a galvanometer as the scanning device,a multi-pixel photon counter as the detector and a field programmable gate array as the main controller.Besides,the photometric stereo algorithm is used to realize the three-dimensional imaging of the object.The research results show that the proposed scheme can realize the rapid and high-resolution 3D imaging of complex objects with low illumination light.The imaging resolution is 512 pixel×512 pixel and the data acquisition time is less than 6.7 s.This scheme can be applied in a long distance 3D imaging system with low illumination light.It also has the potential to be applied in fast developing turbulence-resist imaging system and non-of-sight imaging system.
