Kind Code:
A1
Abstract:
A calibration method for a laser radar system, comprising the following method steps: a laser radar system (230) uses a calibration box (210) to sequentially execute N instances of ranging, the emergent laser of each instance of ranging is delayed for a different length of time and ranging values of N different distances are obtained, and N calibration matrices are obtained according to the difference between a ranging value and a corresponding actual value (S120), N≥1 and N being an integer; and a calibration matrix of a measured value is acquired, and the measured value is calibrated and compensated (S140).
