Title:
DISTANCE MEASUREMENT METHOD AND DISTANCE MEASUREMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/121361
Kind Code:
A1
Abstract:
A distance measurement method and apparatus (100). The method comprises: receiving a plurality of first echo signals generated within a detection range of a plurality of first radar signals transmitted in a first time period (S210); determining a first point cloud dataset according to the plurality of first echo signals (S220); denoising the first point cloud dataset according to a signal-to-noise ratio value and a rate value in each point cloud data included in the first point cloud dataset, to obtain a target dataset (S230), obstacle points in different motion states having different noises and rates; clustering first point cloud data included in the target dataset according to a distance value in each first point cloud data included in the target dataset, to obtain at least one classification, the at least one classification corresponding to at least one obstacle (S240); and determining a distance between the obstacle corresponding to each classification and the emission origin according to the distance value in each first point cloud data included in the each classification in the at least one classification (S250). The distance measurement method and apparatus (100) can improve the accuracy of distance measurement.
