In-vehicle passenger position rapid detection method, detection device, detection equipment and computer readable storage medium

The invention relates to an in-vehicle passenger position rapid detection method, device and equipment and a computer readable storage medium. The method for quickly detecting the position of the passenger in the vehicle comprises the following steps: S1, accumulating to obtain a complex matrix signal; s2, performing cancellation processing on a complex matrix signal at an interval of N frames; calculating power values of two frames before and after the interval of N frames, and solving an absolute value of a power difference; s3, performing primary screening, and performing DBF processing on the complex matrix signals subjected to cancellation processing to obtain angle power values of corresponding distance units; s4, acquiring an accumulated angle power spectrum of each distance unit; s5, performing secondary screening and coordinate system conversion, and generating power point cloud distribution data; and S6, determining the position of the passenger in the vehicle based on the power point cloud distribu
