Panoramic sea view monitoring method and device, server and system

A server comprising:

• a memory configured to store at least one instruction therein;
• and
• a processor configured to perform the at least one instruction to implement;
• aligning any two adjacent monitoring cameras among a plurality of monitoring cameras, so that the any two adjacent monitoring cameras are located on the same physical horizontal plane in a field of view;
• monitoring a panoramic sea view by using the plurality of aligned monitoring cameras and a depth-of-field camera, so as to obtain monitoring images;
• determining a horizontal spacing parameter and a vertical spacing parameter of the any two adjacent monitoring cameras;
• merging the monitoring images in a pairwise manner by using the horizontal spacing parameter and the vertical spacing parameter, so as to construct a two-dimensional scene;
• for each monitoring camera, determining a distance between each point to be calibrated of the monitoring camera and the monitoring camera, and determining an angle formed between each point to be calibrated and the monitoring camera and the depth-of-field camera, wherein each monitoring camera comprises a plurality of points to be calibrated;
• and
• determining a distance and angle calibration curve of the monitoring camera according to the distance and the angle.

A panoramic sea view monitoring system comprising:

• a plurality of monitoring cameras configured to monitor a panoramic sea view in a two-dimensional space;
• a depth-of-field camera configured to collect distance information associated with target monitoring objects in a three-dimensional space, based on monitoring by the plurality of monitoring cameras in the two-dimensional space;
• and
• a server configured to implement:
• aligning any two adjacent monitoring cameras among the plurality of monitoring cameras, so that the any two adjacent monitoring cameras are located on the same physical horizontal plane in a field of view;
