Extrinsic calibration parameter generating device, system, and method

A extrinsic calibration parameter generating method, being adapted for use in an electronic device, wherein the extrinsic calibration parameter generating method comprises:

• receiving an observation data corresponding to a spatial point from each of a plurality of sensors;
• calculating a spatial position of the spatial point indicated by each of the observation data based on the observation data of each of the sensors;
• comparing the spatial position indicated by each of the observation data to determine whether each of the observation data belongs to an outlier value or a normal value;
• and
• in response to the observation data corresponding to a first sensor belonging to the outlier value, generating an extrinsic calibration parameter corresponding to the first sensor based on the observation data of each of at least one second sensor, wherein the observation data of each of the at least one second sensor belongs to the normal value.

An extrinsic calibration parameter generating system, comprising:

• a plurality of electronic devices, wherein each of the electronic devices comprises at least one sensor, and each of the at least one sensor generates an observation data corresponding to a spatial point;
• and
• a processing device, being communicatively connected to the electronic devices;
• wherein the extrinsic calibration parameter generating system is configured to perform operations comprising:
• receiving, by the processing device, the observation data from each of the electronic devices;
• calculating, by the processing device based on the observation data, a spatial position of the spatial point indicated by each of the observation data;
• comparing, by the processing device, the spatial position indicated by each of the observation data to determine whether each of the observation data belongs to an outlier value or a normal value;
• and
• in response to the observation data corresponding to a first sensor belonging to the outlier value, generating, by the processing device, an extrinsic calibration parameter corresponding to the first sensor based on the observation data of each of at least one second sensor, wherein the observation data of each of the at least one second sensor belongs to the normal value.
