Embodiment Construction

[0052]In order to enable those skilled in the art to better understand the solutions of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is an embodiment of a part of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0053] Existing radar manufacturers generally use very complicated tracking algorithms inside the radar, and the processing process is complicated. Moreover, for OEMs, the detection point data in the obtained radar data is folded, and it needs to be unfolded with an algorithm as efficient as possible to obtain the actual radial veloc...

Abstract

The invention discloses a point cloud data processing method, device, controller and radar sensor. The method comprises the following steps that point cloud data at a sensing point and target data corresponding to the sensing point sent by the radar sensor are obtained, wherein the point cloud data at the sensing point comprise distance change rate of the sensing point; the measurement range of the distance change rate at the sensing point of the radar sensor is obtained; the detection point with the distance change rate in the point cloud data beyond the measurement range is extracted; the rate of distance change beyond the measurement range in the point cloud data is adjusted to enable the range change rate in the point cloud data to be consistent with the range change rate in corresponding target data of the sensing point. Repeated calculating is avoided; simpleness and efficiency are achieved; only regional or spatial judgment for each sensing point is needed, and complex trackingis not required; point cloud processing efficiency in the whole procedure is improved; and driving experience of a user is further improved.

Description

technical field [0001] The invention relates to the technical field of intelligent vehicle environment perception, in particular to a point cloud data processing method, device, controller and radar sensor. Background technique [0002] Millimeter-wave radar generally adopts chirp sequence modulation, which emits a series of continuous linear chirp signals, and the time length of a single signal is often only a few microseconds. After the radar transmits a series of signals and receives the reflected signals of various objects in the environment, it will perform a two-dimensional or more than two-dimensional Fourier transform on the received signals, thus obtaining a two-dimensional or more than two-dimensional frequency domain signal; this frequency domain signal is called a frame (frame), which is similar to a frame in a video signal. Wherein, each frame signal includes several valid detection points (detection). Each frame signal includes at least two dimensions, one of...
