Abstract

This article proposes an improved hardware implementation method for phase-based frequency estimation algorithm. Compared with the original algorithm, this paper uses spatial Gabor filtering instead of frequency domain Gabor filtering to avoid complex spatial frequency domain conversion and reduce resource requirements for hardware implementation. The entire algorithm is designed as a pixel stream processing architecture with pipeline blocks, enabling it to easily adapt to common image sensing components with streaming pixel output, while achieving higher performance at lower system costs. This article implements a prototype based on Field Programmable Gate Array (FPGA), which can process up to 100M pixels per second and calculating vibration frequency in real-time.
