Description

{Underwater CCTV device for ships using wireless power transmission}

This design relates to an underwater CCTV device, and more specifically, to an underwater CCTV device for ships using wireless power transmission that checks the status of the bottom of the ship and screws while receiving power using wireless power transmission.

CCTV (closed circuit television) is a system that transmits images to specific recipients using a wired or special wireless transmission path from a specific building or facility to a specific recipient. CCTV is used for a variety of purposes, including industrial, educational, medical, traffic control surveillance, disaster prevention, and internal video information delivery.

Meanwhile, because the ship moves while partially submerged in water, the condition of the bottom of the ship and its screws cannot be checked unless a diver hired by the shipowner directly enters the water or lifts the ship to land. In other words, separate labor is required to check the bottom of the ship and the screws, and as this causes cost losses, many ship owners do not frequently check the condition of the bottom of the ship and the screws.

However, if the condition of the bottom of the ship and screws is not checked frequently, barnacles and foreign substances will attach to the bottom of the ship and screws, causing problems that lower the fuel efficiency of the ship. Research is being conducted to more effectively check the condition of the bottom of the ship and screws.

Thus, a plurality of first hidden node values are calculated.

Subsequently, each of the plurality of second hidden nodes (h21 to h2b) of the second hidden layer (HL2) applies a weight and a threshold to each of the plurality of first hidden node values of the plurality of first hidden nodes (h11 to h1a), and the weights And, an operation according to an activation function is performed on each of the plurality of first hidden node values to which the threshold is applied to calculate a plurality of second hidden node values. In this way, the previous node value within the hidden layer (HL) is passed with a weight applied, and the current node value is calculated through calculation. By repeating this process, a plurality of k-th hidden node values of a plurality of k-th hidden nodes (hk1 to hkc) of the k-th hidden layer (HLk) can be calculated.

Accordingly, the output node (v) of the output layer (OL) applies weights w = [w1, w2, . , wc] is input, the input values are all added up, the threshold is subtracted, and an operation according to the activation function is performed on the value to calculate the output value. The output value calculated by this output node (v) may be an image that estimates the space generated between images captured at neighboring positions among a plurality of images that are input data.
