Method for improving vehicle look-around calibration precision

The invention discloses a method for improving the vehicle look-around calibration precision, and the method comprises the following steps: S1, selecting a point on a calibration station for vehicle look-around calibration as a reference point, and placing a height gauge at the position of the reference point; s2, setting a plurality of measuring points on target blocks serving as target objects, placing laser swingers on different measuring points of each target block, rotating the laser swingers to enable horizontal laser rays to be hit on the height gauge, and further reading the reading of the height gauge; s3, calculating the difference between the height gauge reading corresponding to each measurement point and the theoretical height of the target block to obtain the height error of the measurement point, summing the height errors corresponding to all the measurement points on the same target block, and dividing the sum by the number of the measurement points on the target block to obtain the average he
