Sensor calibration method and device

The invention provides a sensor calibration method and device. The method comprises the following steps: acquiring measurement data of a plurality of attributes acquired by a target sensor and a reference sensor; performing data dimension adjustment on the measurement data of the reference sensor to obtain measurement data of which the data dimension is N * P * K; inputting the measurement data into a prediction model through respective corresponding channels, and outputting prediction data of each attribute corresponding to the target sensor; and on the basis of a Kalman filter, in combination with the measurement data and the prediction data of each attribute of the target sensor, determining calibration data of each attribute of the target sensor. According to the method, the multi-attribute measurement data of the reference sensor are collected, and the data dimension is adjusted to be N * P * K measurement data, so that the multi-attribute measurement data of the reference sensor at multiple moments are
