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: This application provides a method and an apparatus for updating a working map of a mobile robot, and a storage medium in the field of intelligent control technologies. The method includes: determining a plurality of detected environment maps based on object distribution information detected by the mobile robot in a moving process; merging the plurality of detected environment maps to obtain a merged environment map; and then performing weighting processing on the merged environment map and an environment layout map currently stored in the mobile robot, to obtain an updated environment layout map. The environment layout map stored in the mobile robot is updated by using the plurality of detected maps obtained by the mobile robot during working, so that the updated environment layout map can reflect a more detailed environment layout. This helps the mobile robot subsequently better execute a working task.

Abstract: A sound source positioning method and apparatus, a computer-readable storage medium, and a sound pickup apparatus are provided, for accurately locating a sound source by using a microphone array and a radar. The method includes: obtaining first location information by using echo data of a radar (201), where the first location information includes a first angle of an object relative to the radar; obtaining an incident angle by using a voice signal captured by a microphone array (202), where the incident angle is an angle at which the voice signal is incident to the microphone array; and fusing the first angle and the incident angle to obtain second location information (205), where the second location information indicates a location of a sound source generating the voice signal.

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.
