Marine object detection method and device under low visibility and electronic equipment

The invention relates to the field of object detection, and discloses a sea object detection method and device under low visibility and electronic equipment. The method comprises the following steps: determining visibility information of a sea surface; under the condition that the visibility information meets a preset condition, adjusting the scanning range of the radar and controlling the radar to execute scanning operation on the current sea area so as to confirm other objects of the current sea area; determining the opening type of the current sea area through a target object detection system according to the target object of the current ship; detecting a detection blind area of the object detection system through the AIS system, and further confirming other objects of the current sea area; and determining the position relationship between the current ship and other objects according to the object and the opening type of the current ship. Visibility information of the sea area is obtained in real time, and
