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.
