Abstract: The present disclosure relates to distance measurement methods and apparatuses. One example method includes receiving multiple first echo signals, determining multiple first spectrum data groups based on the multiple first echo signals, performing normalization processing on a signal strength value corresponding to each distance value comprised in each first spectrum data group to obtain a normalized signal strength value corresponding to each distance value, determining, based on a normalized signal strength value, a variance value of a signal strength value corresponding to each distance value comprised in the multiple first spectrum data groups, and determining a distance between a target obstacle on the to-be-measured object and the transmitting origin based on the variance value of the signal strength value corresponding to each distance value comprised in the multiple first spectrum data groups.

Abstract: A gesture recognition method and a related apparatus are provided, to obtain a first point cloud data set by filtering an original point cloud data set collected by a radar apparatus. The first point cloud data set includes a plurality of frames of first point cloud subsets, the first point cloud subset includes a first cluster center, the first cluster center is a cluster center of a plurality of pieces of point cloud data in the first point cloud subset, a maximum horizontal distance between any two first cluster centers meets a first preset condition, and duration of the first point cloud data set meets the first preset condition. Point cloud data whose motion track does not match gesture motion can be effectively filtered out. Gesture recognition is performed by using the first point cloud data set obtained by filtering.
