This application discloses a radar-based method and device for generating a 3D point cloud of a target object. The radar sends a chirp signal, receives the chirp echo and performs sampling and Fourier transformation to obtain a second data matrix. Based on the second data matrix Perform azimuth CAPON beamforming to obtain the third data matrix, and calculate the data in the third data matrix through constant false alarm detection to determine each target point; For the azimuth angle of the target point, perform CAPON beamforming on the data corresponding to each target point in the second data matrix, and calculate the elevation angle of each target point, thereby generating a three-dimensional point cloud of each target point. Compared with the traditional solution, the technical solution provided by this application can generate a three-dimensional point cloud of the target point, which is beneficial to achieve more accurate positioning.
Description
technical field [0001] The present application relates to the field of radar detection, and in particular, to a method and device for generating a three-dimensional point cloud of a target object based on radar. Background technique [0002] With the development of the information age, the demand for spatial data in all walks of life is increasing day by day, and conventional data acquisition methods and data processing modes can no longer meet the needs of informatization. [0003] In the prior art, in the fields of surveying and mapping, member detection, member positioning, etc., traditional radar detection or radar positioning technology is generally based on a two-dimensional fast Fourier transform (FFT, fast Fourier transform) or a one-dimensional CAPON algorithm. However, these methods have the problem of not being able to generate 3D point clouds, resulting in low data accuracy, inability to accurately locate, limited application scenarios, and increasingly unable to...
