Abstract:
In this study, we describe a Time-of-Flight scanning LiDAR (Light Detection and Ranging) prototype, that leverages MEMS mirrors for agile beam steering and an FPGA-based processing unit for real-time 3D image reconstruction. The proposed 3D-LiDAR system is designed to operate within a range of up to 1 meter with a spatial resolution of 400 × 300 pixels at a frame rate of 30 Hz. Lidar prototype architecture consists of 3 main parts: optomechanical System; Digital Processing Unit (FPGA-based); analog front-end. Processed 3D depth maps are rendered in real-time via an HDMI interface, providing immediate visual feedback. The integration of MEMS mirrors, FPGA-based Time-to-Digital Converter, and an optimized analog front-end resulted in a highly efficient, compact, and real-time depth-sensing platform.
