The embodiment of the invention relates to the technical field of automobile radar, and discloses an angle self-calibration method, an automobile radar system and an automobile. The angle self-calibration method is applied to the automobile radar system, the automobile radar system is included, the automobile radar system is installed on an automobile, and the method comprises the steps of detecting whether the automobile is in a linear driving state or not; if yes, marking a plurality of reference points in a target list formed by target points currently collected by the automobile radar; detecting whether the plurality of reference points are located on the same straight line in an actual scene or not; if yes, calculating an offset angle of the automobile radar according to the pluralityof reference points; and compensating the automobile radar according to the deviation angle. According to the embodiment of the invention, the angle self-calibration of the automobile radar can be realized.
Description
Technical field [0001] The invention relates to the technical field of automotive radars, in particular to an angle self-calibration method, automotive radar systems and automobiles. Background technique [0002] Automotive radars are radars used in automobiles or other ground-based motor vehicles, including various radars based on different technologies (such as laser, ultrasonic, microwave), which can be used to find obstacles, predict collisions, and adaptive cruise control. When the car radar is first installed on the car, an angle calibration will be performed. However, as the car travels for a long time, due to bumps and other reasons, the installation angle of the car radar may be horizontally shifted, which causes the angle data of the target points around the car detected by the car radar to also be horizontally shifted. When the installation angle of the car radar has a large horizontal deviation, it may even cause the car radar to produce false alarms and false alarms...
