In this embodiment, the electronic device obtains first trajectory data from the server, where the first trajectory data is trajectory data of a ship in an actual sailing process acquired through a terminal, and the first trajectory data includes a plurality of historical trajectory point locations.
It should be noted that the first trajectory data includes a plurality of historical trajectory points, and each historical trajectory point includes timestamp information, longitude information, latitude information, and heading information. Different ships may have different data sources, so the acquisition frequency of the historical track points of different ships may be different.
Illustratively, the historical track points of the first vessel are collected once in 5 seconds and the historical track points of the second vessel are collected once in 2 minutes.
In this embodiment, the play request input is an operation input performed by the user on the electronic device, and the play request input is used to control the electronic device to play the navigation trajectory animation of the ship based on the first trajectory data. The playing request input comprises first time information, and the first time information is the time corresponding to the navigation track animation which the user needs to view. The electronic equipment screens historical track point locations in the first track data through the first time information, a first track point set can be obtained, the acquisition time of the first track point set is matched with the first time information, and the first track point set is historical navigation point locations corresponding to navigation tracks which need to be checked by users.

As shown in fig. 3, in any of the above embodiments, acquiring the first trajectory data includes:
and step 306, sequencing the second track data and the third track data according to the acquisition time to obtain first track data.
The second track data and the third track data are stored in the server in the form of data packets, and the data volume of the second track data is matched with that of the third track data.
In this embodiment, the first trajectory data is stored in a server, and the electronic device is capable of acquiring the trajectory data in the server. And the track data in the server is stored in a data packet mode. The electronic equipment can acquire one data packet in the server once and search other data packets corresponding to the data packet based on the data identification in the data packet.
Specifically, when the amount of trajectory data stored in the server is large, the server can perform the splitting process on the trajectory data. The track data is collected from the ship terminal, then is cleaned by big data, and is processed into a standard structure for storage. Therefore, the size of the trace data transmission packet can be roughly calculated according to the data of the trace point. And finally, segmenting according to the number of the track points to obtain a plurality of data packets. Under the condition that the server receives a first data request sent by the electronic equipment, the server transmits one of a plurality of data packets back to the electronic equipment as second track data. Because each data packet stores a data identifier, the electronic device can request the server for third trajectory data related to the second trajectory data according to the data identifier. After the electronic equipment acquires the plurality of associated data packets stored in the server, the electronic equipment can perform sequencing according to the acquisition time of each data packet to obtain first track data.

And after the server receives the second data request every time, the server sends a data packet which is not sent to the electronic equipment as third trace data. After receiving the second data requests for the preset times, the server realizes that the rest number of data packets are all sent to the electronic equipment in the form of third trace data.
Illustratively, the electronic device acquires the second track data by sending the first data request, and knows whether to acquire all track data in the server and the remaining number of data packets in the server according to the data identifier of the second track data. And under the condition that the remaining number of the server data packets is not 0, simultaneously sending a second data request to acquire subsequent data, wherein the second data request is an asynchronous data request. For example: the second data area request comprises 'nth packet data (n can be null, default 1)', and the electronic equipment returns third trace data according to the server to judge whether subsequent data needs to be loaded in a segmented asynchronous mode. And if the subsequent data are required to be loaded, asynchronously loading the subsequent data according to the total data of the data segments. I.e., concurrently requesting n-1 times of subsequent data, the previously acquired trajectory data need not be acquired again.
