Embodiment 1

[0027] Such as figure 1 As shown, the product of this embodiment is a ship water gauge measurement system based on unmanned aerial vehicles, including a ship 1 with a water gauge scale 11, and also includes:

[0028] The UAV water gauge video acquisition device 2 is configured to track changes in the position of the waterline area;

[0029] The terminal collection device 3 (i.e. a handheld data collection terminal) is configured to collect the density of seawater and the liquid level of the water and oil tank;

[0030] The data receiving device 4 is configured to receive the data transmitted from the above two devices;

[0031] The data processing server 5 is configured to process the data transmitted from the data receiving device 4, and combine the data to calculate the ship's load capacity.

[0032] The drone water gauge video acquisition device 2 of the present embodiment includes a drone 21, a camera 22 and a remote control system 23. The drone 21 can fly stably over th...

Embodiment 2

[0037] A water gauge measurement method based on the above-mentioned embodiment system, the UAV water gauge video acquisition device 2 is used to track the change of the position of the waterline area; the terminal acquisition device 3 is used to collect seawater density and the liquid level height of the water and oil tank ; The data receiving device 4 is used to receive the data transmitted from the above two devices; the data processing server 5 is used to process the data transmitted from the data receiving device 4, and calculate the load capacity of the ship in combination with the data.

[0038] After the ship 1 docks at the port, the water gauge inspection personnel manipulate the UAV 21 carrying the camera (i.e. the camera 22) into the docking area of ​​the ship 1, and the images collected by the UAV 21 equipped with the camera are sent back to the control platform of the UAV 21 in real time. On the screen, the water gauge acceptance personnel adjusts the hovering posi...

Abstract

The invention relates to a system and method for ship water gauge measurement based on a UAV. The system and method comprise a ship with water gauge scales. The system is characterized by comprising an UAV water gauge video collection device, a terminal collection device, a data receiving device and a data processing server, wherein the UAV water gauge video collection device is configured to track changes of the position of a waterline area; the terminal collection device is configured to collect seawater density and the liquid level height of a water-oil cabin; the data receiving device is configured to receive data sent by the two devices; and the data processing server is configured to process the data sent by the data receiving device and compute the load capacity of the ship according to the data. The system and method mainly aim at data collection, transmission and processing during computation of the ship load capacity; and just and efficient computation of the ship load capacity can be ensured.

Description

technical field [0001] The present invention relates to a ship water gauge measurement system and method based on an unmanned aerial vehicle, in particular to a set of ship load calculation system, specifically an intelligent measurement system applied to port shipping weight, mainly for the calculation process of ship load Data collection, transmission and processing in the middle to ensure the fairness and efficiency of ship load calculation. Background technique [0002] Ship water gauge measurement needs to collect the water gauge scale, seawater density, and the liquid level of the water and oil tanks. When collecting the ship water gauge, it is necessary to drive a small boat to carry the commodity inspection personnel, the receiver and the shipper to observe the ship's bow, midship, There are a total of 6 water scales on both sides of the stern. Due to the small draft of the water gauge boat and the presence of waves, the stability of the boat is poor, which poses a g...
