Abstract

The invention discloses a calibration system and method. The calibration system is used for calibrating vehicle radar during the installation process of the radar, and comprises a transmitting deviceand a receiving device, wherein the transmitting device is arranged at a predetermined position and used for transmitting a calibration signal, and the calibration signal is used for indicating the calibration performed on the installation position of the radar on a vehicle; and the receiving device is arranged together with the radar and used for receiving the calibration signal transmitted by the transmitting device and determining whether there is deviation or not between the current installation position of the radar and a specified installation position according to the received calibration signal. The calibration system solves a technical problem of low calibration efficiency of radar sensors in the related art.

Description

technical field [0001] The present invention relates to the field of radar detection, in particular to a calibration system and method. Background technique [0002] In the process of installing the radar sensor to the vehicle, due to the existence of installation mechanical deviation, there is a deviation between the beam emitted by the radar sensor antenna and the actual requirements, which reduces the effective target recognition rate of the radar sensor. When targeting active safety functions such as ACC and AEB, the radar sensor Installation deviations can even cause these functions to fail. At present, there are few methods for installing and calibrating vehicle radar sensors. Some existing methods have complex devices, complicated calibration process, low calibration efficiency, poor versatility, and high economic cost. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invent...
