Abstract
(EN)
A target detection method, a system, and a computer-readable storage medium. Said method comprises: acquiring a scattering point set by means of a radar sensor, the scattering point set comprising a plurality of scattering points; dividing the plurality of scattering points into at least one region according to feature information about the scattering points; and for the scattering points in each region, performing target detection on the scattering points in the region according to detection parameters corresponding to the region, the detection parameters being configured for different regions respectively. The embodiments of the present invention are able to be applied to effectively distinguish a stationary object from a moving object, improving the accuracy of target detection, and improving the efficiency of target detection.
