Abstract
A dynamic calibration method for heterogeneous sensors includes: sensing dynamic objects by a first sensor to generate first sensing data; sensing the dynamic objects by a second sensor to generate second sensing data; performing feature matching between the first sensing data and the second sensing data to determine first valid data and second valid data, and identifying a tracked object from the dynamic objects based on the first valid data and the second valid data; performing feature comparison between the first valid data and the second valid data corresponding to the tracked object to calculate data errors between the first sensor and the second sensor; and calculating a calibration parameter based on the first valid data and the second valid data when the number of the data errors exceeds an error threshold, and adjusting the first sensing data and the second sensing data based on the calibration parameter.
