The invention belongs to the field of ultrasonic radar calibration, and in particular relates to an ultrasonic radar calibration device and method. The ultrasonic radar calibration device of the present invention is composed of an ultrasonic radar installation platform, a calibration board, a calibration column and a central control machine. The calibration column moves on the calibration board according to the set route, and when passing through the center of the grid on the calibration board, it is positioned by the two-dimensional code and Stop, identify the two-dimensional code to determine the grid position number, send the grid position number to the central control computer through MCU2, and the central control computer obtains the radar height and the distance value detected by the radar from MCU1, and passes each square The location number, radar height and distance value data corresponding to the cell are recorded in groups. Compared with the prior art, the invention can effectively reduce the workload of personnel and improve the calibration efficiency and precision.
Description
technical field [0001] The invention belongs to the field of ultrasonic radar calibration, and in particular relates to an ultrasonic radar calibration device and method. Background technique [0002] Ultrasonic radar has been widely used in automatic parking and reversing collision avoidance due to its low price and good short-distance ranging capability. In the application of automatic parking, it is necessary to detect the parking space through the ultrasonic radar. Since the detection angle exists when the ultrasonic radar detects the object, it cannot accurately judge the lateral position of the obstacle, which has a great impact on the detection accuracy of the parking space. In order to eliminate or reduce the impact of ultrasonic radar detection angle on the detection accuracy of parking spaces, it is extremely important to calibrate its detection range. However, the current calibration methods are manual calibration, which is time-consuming and laborious, and the c...
