[0003] The methods for obtaining water gauge readings in related technologies generally include: manual observation, but manual observation has problems such as subjectivity and environmental limitations, which makes it difficult to ensure data accuracy; through image acquisition equipment, such as pole-mounted cameras, image acquisition equipment cannot effectively resist the erosion of sea breeze and humidity, which can easily lead to equipment damage and performance degradation. At the same time, water gauge readings are obtained through RGB image processing methods, but when abnormal weather conditions such as cloudy or foggy occur, the accuracy is poor and the water gauge readings will have serious deviations.

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] In this embodiment, if Figures 1 to 5 As shown, the ship draft gauge and weighing detection device includes a data acquisition component 1, which includes a first shell 11 and a multispectral camera 12. The first shell 11 has an installation cavity, and the first shell 11 is provided with an opening 111 connected to the installation cavity; the multispectral camera 12 is arranged in the installation cavity, and the camera head of the multispectral camera 12 is arranged opposite to the opening 111 and is sealed with the inner wall of the opening 111.

[0027] For example, the first housing 11 is made of polycarbonate. Polycarbonate has high impact strength, is not easily broken, helps reduce weight, is corrosion-resistant, and does not shield signals, facilitating wireless signal transmission by the multispectral camera 12. The material of the first housing 11 can be changed as needed and is not intended to limit the present invention.

[0028] It can be understood that by providing the first shell 11 and setting the multispectral camera 12 in the first shell 11, the multispectral camera 12 can be protected by the first shell 11, reducing the corrosion of the multispectral camera 12 by seawater, rainwater, etc., which is conducive to the stable and reliable operation of the multispectral camera 12; in addition, the multispectral camera 12 is used to obtain image information such as the waterline, hull and related characters. The multispectral camera 12 can collect one RGB image information and multiple multispectral image information. Since water and the hull have different degrees of reflection of light of different wavelengths, and at the same time, the water body appears black under the collection of the multispectral camera 12, it can reduce the influence of water body reflection, wave light and other factors on subsequent identification, and the multispectral camera 12 collects radiation in different bands. The light in these bands is less affected by weather conditions, thereby improving the accuracy of the detection results.

[0029] In this embodiment, if Figure 1 and Figure 2 As shown, the first housing 11 includes a first shell 112 and a second shell 113. The first shell 112 includes a first support plate and a side plate arranged around the first support plate. The second shell 113 is arranged on a side of the first support plate facing away from the first support plate and is detachably connected to the first shell 112. The opening 111 is provided in the second shell 113.

[0030] For example, the main view of the first shell 112 and the second shell 113 has a square shape. The first shell 112 and the second shell 113 can be connected by screws. Specifically, connecting columns are provided at the four corners of the first shell 112, and each connecting column is provided with a threaded hole, and the second shell 113 is provided with through holes corresponding to the threaded holes. The second shell 113 is placed against the first shell 112, and the screws are passed through the through holes of the second shell 113 and threaded into the threaded holes. The connecting columns can be integrally formed with the first shell 112, which can improve the connection strength of the connecting columns, thereby improving the reliability of the connection between the first shell 112 and the second shell 113.

[0031] In this embodiment, the first housing 112 and the second housing 113 are provided to form a mounting cavity therebetween. Furthermore, the first housing 112 and the second housing 113 are detachably connected, facilitating installation and removal of the multispectral camera 12. The opening 111 provided in the second housing 113 allows the camera of the multispectral camera 12 to capture images, thereby ensuring that the multispectral camera 12 is usable and protected by the first and second housings 112, 113.

[0032] In this embodiment, if Figure 2 As shown, the data acquisition assembly 1 further includes a battery 13 , which is disposed in the installation cavity and electrically connected to the multispectral camera 12 to supply power to the multispectral camera 12 .

[0033] For example, the battery 13 can be a lithium battery. Lithium-ion batteries have high energy density, cycle life and light weight, are easy to use, and are beneficial to improving user experience. Of course, the battery 13 can also be set to other types of batteries, which is not limited here.

[0034] Specifically, the battery 13 and the multispectral camera are spaced apart in the longitudinal direction of the main view of the first housing 11 , and a cavity is reserved above the multispectral camera to facilitate the arrangement of cables between the battery 13 and the multispectral camera.

[0035] It is understandable that the battery 13 can be provided to improve the endurance of the ship draft gauge and weight detection device, and the multi-spectral camera can be powered in time for easy use.

[0036] In this embodiment, if Figure 2 and Figure 3 As shown, the first housing 11 has an isolating member 114 , which is located in the mounting cavity. The isolating member 114 abuts against the outer peripheral surface of the battery 13 to form a gap between the battery 13 and the inner wall of the first housing 11 .

[0037] Specifically, the isolation member 114 includes multiple partitions 1141 and multiple protrusions 1142. The partitions 1141 and the inner wall of the first shell 11 form a first accommodating space for accommodating the battery 13. The multiple protrusions 1142 are arranged at intervals on the partitions 1141 or the inner wall of the first shell 11. The battery 13 is limited by the protrusions 1142, and a gap is formed between the battery 13 and the partitions 1141 or the inner wall of the first shell 11, so that the interior can be ventilated and heat dissipation can be facilitated.

[0038] It is understandable that by arranging the isolating member 114 in the first shell 11, a gap is formed between the outer peripheral surface of the battery 13 and the inner wall of the first shell 11, so that there is space for air circulation between the battery 13 and the inner wall of the first shell 11, thereby facilitating heat dissipation.

[0039] In this embodiment, the spacer 114 abuts against the outer peripheral surface of the multispectral camera 12 , so that a gap is formed between the multispectral camera 12 and the inner wall of the first housing 11 .

[0040] Likewise, if Figure 2 and Figure 3 As shown, a plurality of partitions 1141 and a plurality of protrusions 1142 are arranged around the multispectral camera 12. The battery 13 and the multispectral camera 12 can share one partition 1141. The partition 1141 and the inner wall of the first shell 11 form a second accommodation space. The multispectral camera 12 is located in the second accommodation space. The plurality of protrusions 1142 are arranged at intervals on the partition 1141 or the inner wall of the first shell 11, so that a gap is formed between the multispectral camera 12 and the inner wall of the first shell 11 and the partition 1141.

[0041] It can be understood that by arranging the isolation member 114 in the first shell 11, a gap is formed between the outer peripheral surface of the multispectral camera 12 and the inner wall of the first shell 11, so that there is space for air circulation between the multispectral camera 12 and the inner wall of the first shell 11, thereby facilitating heat dissipation.

[0042] In this embodiment, the data acquisition component 1 further includes a fill light, which is disposed on the housing and electrically connected to the battery 13 .

[0043] Specifically, if Figures 1 to 3 As shown, a bracket 14 can be provided on the outer wall of the first housing 11 , and the fill light is fixed to the bracket 14 , which can facilitate the installation of the fill light. The fill light can be powered by a battery 13 .

[0044] It is understandable that by setting up a fill light, stable lighting can be provided during shooting, which is conducive to improving the quality of shooting.

[0045] In this embodiment, if Figure 4 As shown, the data acquisition assembly 1 further includes a telescopic rod 15 , which is connected to the first housing 11 .

[0046] Specifically, the telescopic rod 15 includes a handheld end and a connecting end at both ends along its length. The handheld end is convenient for the operator to hold, and the connecting end is connected to the first housing 11, allowing the operator to hold the handheld end to shoot. The telescopic rod 15 can be made of carbon material to ensure the strength of the telescopic rod 15 while reducing its weight.

[0047] It is understandable that by providing the telescopic rod 15 , the telescopic rod 15 can be extended or shortened according to usage needs for shooting, thereby improving the convenience of shooting.

[0048] In this embodiment, if Figure 4 As shown, the data acquisition assembly 1 further includes an adjusting member 16 , which is disposed on the telescopic rod 15 . The first housing 11 is connected to the adjusting member 16 , and the adjusting member 16 is used to adjust the angle of the first housing 11 .

[0049] Specifically, the adjustment member 16 includes a connecting sleeve 161, a connecting shaft 162, and an adjustment rod 163. One end of the connecting sleeve 161 is sleeved on the connecting end of the telescopic rod 15, and one end of the connecting shaft 162 is rotatably disposed within the connecting sleeve 161. The first housing 11 is provided with a connecting portion, and the other end of the connecting shaft 162 is connected to the connecting portion. The adjustment rod 163 is threaded along the radial direction of the connecting sleeve 161, passes through the side wall of the connecting sleeve 161, and abuts against the connecting shaft 162. When the adjustment rod 163 is tightened, the connecting shaft 162 can be fixed, thereby fixing the first housing 11 via the connecting shaft 162. When the adjustment rod 163 is loosened, the connecting shaft 162 can be rotated, thereby driving the first housing 11 to rotate via the connecting shaft 162.

[0050] In this embodiment, by providing the adjustment member 16, the angle of the first housing 11 can be adjusted by the adjustment member 16, thereby adjusting the shooting angle of the multispectral camera 12 through the first housing 11, thereby improving the flexibility of shooting and improving the user experience.

[0051] In this embodiment, a first switch (not shown in the figure) for controlling the multispectral camera 12 to be turned on or off is provided on the first housing 11 .

[0052] Specifically, a switch opening is provided on the first housing 11 , and the first switch is installed at the switch opening.

[0053] It is understandable that by setting the first switch, the multispectral camera 12 can be controlled to be turned on or off by the first switch, which is practical and convenient.

[0055] For example, the control processing unit can include the second-generation Jiaolong 8 high-performance computing chip. By carrying various deep learning algorithms with the control unit, it has a WiFi function and can transmit images point-to-point with the multi-spectral camera 12 through the WiFi antenna 22, and can mobilize the computing power of its own chip to quickly complete the reading and weighing of the water gauge image, such as Figure 6 The specific composition of the control unit and the specific connection method with the Wifi antenna 22 and the display screen 23 are conventional existing technologies and will not be described in detail here.

[0056] Specifically, the second housing 21 is further provided with a charging interface, which is electrically connected to the power module of the control unit for charging. The second housing 21 is also provided with a second switch to control the on and off of the display screen 23 through the second switch.

[0057] It can be understood that the image information sent by the multispectral camera 12 is received through the wifi antenna 22 to realize data transmission, the control processing unit receives and processes the received image information through the internal algorithm, analyzes it in real time and displays the weight through the display screen 23.

[0058] In this embodiment, if Figure 5 As shown, the receiving component 2 further includes a data transmission interface 24 , which is disposed in the second housing 21 and electrically connected to the control processing unit. The data transmission interface 24 is configured to transmit image information to a host computer.
