W = d ₁ -D ₁ -D ₂

In addition, when the ship 10 moves from the sensor device 20 installed on the left side of the ship 10 to the sensor device 20 installed on the right side of the ship 10 from each sensor device 10 from the ship 10 Using the bow detection time (t ₁₁ , t ₂₁ ) or the stern detection time (t ₁₂ , t ₂₂ ) of) is obtained by the equation (6).

T = T ₁ = t ₂₁ t ₁₁ or T = T ₂ = t ₂₂ t ₁₂

On the other hand, the travel time (T) of the vessel 10 is the bow and stern movement time (T ₁ ) of the vessel 10 from the sensor device 20 installed on the left to the sensor device 20 installed on the right side of the ship 10 , T ₂ ) can be taken.

At this time, the vertical distance (d2) between the sensor device 20 installed on both sides of the vessel 10 is a predetermined value, the sensor device 20 installed on the right side of the vessel 10 in the sensor device 20 installed on the left side. The moving speed (V) of the ship 10 between) is obtained by the equation (7) using the moving time (T) of the ship (10).

V = V ₁ = d ₂ / T ₁ or

V = V ₂ = d ₂ / T ₂ or

V = V ₃ = d ₂ / T _avg = d ₂ / {(T ₁ + T ₂ ) / 2}

On the other hand, the moving speed of the ship (10) (V) may take an average value of the moving speed (V _1, V ₂₎ calculated by the movement time of each of the players and the stern.

In addition, the electric field information (L) is the movement time (t ₁ , t ₂ ) of the ship 10 in the sensor device 20 installed on the left side of the ship 10 or the sensor device 20 installed on the right side of the ship 10. And, using the moving speed (V) between the respective sensor device 20 is obtained by the equation (8).

L = L ₁ = V × t ₁ = V × (t ₁₂ t ₁₁ ) or

L = L ₂ = V × t ₂ = V × (t ₂₂ t ₂₁ ) or

L = L ₃ = V × t _avg = V × {(t ₁ + t ₂ ) / 2}

On the other hand, the electric field information (L) can take the average value of the electric field information (L ₁ , L ₂ ) obtained by the movement time of the vessel 10 in each sensor device 20.

That is, according to the method, the sensor device 20 moves the moving vessel 10 in real time between the distance between the sensor apparatus 20 and the vessel 10, D ₁ , D ₂ , and the sensor apparatus 20. It was illustrated that the full width and the length information of the ship 10 were obtained using the speed V and the travel time t in the sensor device 10.

On the other hand, although not shown, the sensor device incorporating a distance sensor and a camera sensor is installed at the entrance of the marina facility, and when the ship approaches the entrance to the marina facility, the distance sensor is used to detect the distance between the ship and the sensor device, and the camera The sensor is used to acquire an image including the ship.
