The method comprises: a source station sending position information thereabout, and after a signal propagation time delay calculated according to both the position information about the source station and the position information about a station to be synchronized is acquired, the station to be synchronized synchronizing with the source station according to a synchronization reference time which is obtained by advancing a receiving time of a first network reference signal received from the source station by the propagation time delay. It can be seen that the station to be synchronized uses the signal propagation time delay between same and the source station to compensate for a receiving time of the first network reference signal in the process of synchronizing with the source station. Therefore, the consumed propagation time delay can be deducted from the synchronization reference time, thereby improving the synchronization accuracy.

The methods may include performing one or more checks on captured image data of the environment, wherein performing each of the one or more checks comprises determining whether the environment satisfies a respective criterion. The method may further include determining that the environment is suitable or unsuitable for performing the 3D scan based on a result of each performed check. Determining that the environment is suitable for performing the 3D scan may include determining that the environment satisfies each of the respective criteria of the performed one or more checks. Determining that the environment is unsuitable for performing the 3D scan may include determining that the environment does not satisfy at least one criterion of the performed one or more checks. Related devices and computer program products are also provided.
