摘要

This paper proposes a multi-person action recognition system based on frequency modulated continuous wave radar (FMCW). First, a Gaussian mixture model clustering method (GMM) is used to extract the active point cloud data of a single person from the data collected by the radar. Then point cloud nearest neighbor sampling algorithm is proposed for processing the radar point cloud data. Eventually, ...
