Query: Eventor: An Efficient Event-Based Monocular Multi-View Stereo
  Accelerator on FPGA Platform   Event cameras are bio-inspired vision sensors that asynchronously represent
pixel-level brightness changes as event streams. Event-based monocular
multi-view stereo (EMVS) is a technique that exploits the event streams to
estimate semi-dense 3D structure with known trajectory. It is a critical task
for event-based monocular SLAM. However, the required intensive computation
workloads make it challenging for real-time deployment on embedded platforms.
In this paper, Eventor is proposed as a fast and efficient EMVS accelerator by
realizing the most critical and time-consuming stages including event
back-projection and volumetric ray-counting on FPGA. Highly paralleled and
fully pipelined processing elements are specially designed via FPGA and
integrated with the embedded ARM as a heterogeneous system to improve the
throughput and reduce the memory footprint. Meanwhile, the EMVS algorithm is
reformulated to a more hardware-friendly manner by rescheduling, approximate
computing and hybrid data quantization. Evaluation results on DAVIS dataset
show that Eventor achieves up to $24\times$ improvement in energy efficiency
compared with Intel i5 CPU platform.
