Method and apparatus for obtaining information about object using plurality of sensors

A navigation assistance system using a plurality of sensors, comprising:

• a display configured to provide a monitoring image;
• a sensor unit comprising at least one sensor;
• a memory in which at least one program is stored;
• and
• at least one processor configured to execute the at least one program,
• wherein the at least one processor is configured to
• obtain image frame information of an object using a first sensor,
• calculate information about the object using a second sensor from a multi-dimensional object area generated based on the image frame information of the object,
• calculate a risk of collision between a host ship and the object by fusing the image frame information of the object and the information about the object, and
• determine an avoidance path based on the calculated collision risk.
