Title:
IN-VEHICLE LIFE DETECTION METHOD AND APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/166649
Kind Code:
A1
Abstract:
Provided are an in-vehicle life detection method and apparatus, an electronic device, and a computer readable storage medium, which are applicable to to the technical field of intelligent vehicles. The method comprises: obtaining an xth radar frame signal acquired by a preset millimeter wave radar in a vehicle (S110); performing demodulating sampling and time-frequency transformation on the xth radar frame signal, so as to obtain a first distance dimensional signal array (S120); filtering the first distance dimensional signal array, so as to obtain a second distance dimensional signal array (S130); extracting a phase and confidence of a preset detection point from the second distance dimensional signal array (S140); according to a phase and confidence of the preset detection point of an (x-1)th radar frame signal extracted in advance, iteratively filtering the phase and the confidence of the preset detection point of the xth radar frame signal, so as to obtain a filtering result of the preset detection point of the xth radar frame signal (S150); and when the filtering result is greater than a preset threshold, determining that a life exists at the preset detection point (S160). The present method is suitable for in-vehicle life detection in a variety of scenarios, and the detection effect is good.
