Description

Technical Field

[0001] This utility model relates to the field of imaging technology, and in particular to a mountable agricultural inspection device. Background Technology

[0002] The development and promotion of modern agricultural technologies are constrained by considerations of input costs and returns. In the vast plains crop-producing areas, large-scale, mechanized environmental agriculture operates with a high degree of automation. However, in hilly areas, due to limitations imposed by terrain and environmental factors, small-scale semi-automated machinery and manual labor are the primary methods of operation.

[0003] Overall, my country's agricultural development continues to focus on improving the coverage of mechanized and automated operations while also exploring intelligent technologies. This includes investments in fixed infrastructure such as targeted pest monitoring and intelligent water-saving irrigation systems, and the gradual promotion of mobile agricultural machinery such as automated sowing and harvesting, and drone-based plant protection subsystems for specific applications. However, a solution that simultaneously meets the productivity needs of plant protection and mobile agricultural machinery, fulfills the inspection and maintenance functions of fixed infrastructure, and achieves cost control and adaptability to various scenarios is difficult to realize. Utility Model Content

[0004] The purpose of this invention is to provide a mountable agricultural inspection device to overcome or at least mitigate at least one of the aforementioned defects of the prior art.

[0005] To achieve the above objectives, this utility model provides a mountable agricultural inspection device, which includes multiple camera components, a 4G / 5G communication module, and a GPS positioning module. The GPS positioning module is installed in the hollow cavity of the first housing. The bottom surface of the first housing is detachably fixed to the agricultural machinery. In use, all the camera components are distributed around the axis of the agricultural machinery along its height direction. The 4G / 5G communication module is located in the central area formed by the camera components. The fields of view of two adjacent camera components overlap, forming a 360° seamless surround view coverage around the axis of the agricultural machinery's height direction.

[0006] Furthermore, in the aggregated deployment state, there are 6 trapezoidal cross-section columnar camera components, with the sides of two adjacent camera components touching each other, and the field of view of each camera is not less than 60°. The 6 camera components are distributed in a hexagonal prism shape around the 4G / 5G communication module.

[0007] Furthermore, in the separate deployment state, there are 6 camera components, of which 2 camera components are set back to back on the top of the agricultural machinery chassis, and the remaining 4 camera components are fixed to the support feet of the chassis respectively, and the overlapping area of ​​the fields of view of adjacent cameras covers the 360° circumference of the agricultural machinery.

[0008] Furthermore, the back of the camera assembly is detachably connected to the outer plane of the 4G / 5G communication module via magnetic attraction.

[0009] Furthermore, each camera component includes a camera module, and each camera module is provided with an accessory. The accessory is detachably connected by magnetic attraction and is used to magnetically connect two camera components to each other, or to magnetically connect the camera components to the 4G / 5G communication module 2.

[0010] Furthermore, the mounted agricultural inspection device also includes a data collector, which is installed together with the GPS positioning module in the hollow cavity of the first housing.

Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0023] The mountable agricultural inspection device provided in this embodiment of the utility model includes multiple camera components 1, a 4G / 5G communication module 2, and a GPS positioning module, wherein:

[0024] like Figure 1a , Figure 1b , Figure 2a and Figure 2b As shown, the GPS positioning module is installed in the hollow cavity of the first housing 3. The bottom surface of the first housing 3 is fixed to the agricultural machinery A by means of detachable connection such as magnetic joint surface 31 or bolt connection 32.

[0025] The 4G / 5G communication module 2 includes a second housing and a communication network card installed inside the second housing. The 4G / 5G communication module 2 is fixed to the top surface of the first housing 3 by its mounting hardware. The communication network card can be, for example, an existing product on the market such as the EC20-MINIPCIE communication network card.

[0026] Each camera component 1 includes a camera module, which can be an existing product such as an IMX577 camera module or a USB camera. It supports surround-view assembly and discrete component mounting. The camera module's lens can be replaced with different focal length lenses, such as 60°, 90°, 120°, and 180°, to capture image frames within the field of view in real time. The camera module uses a starlight-level image sensor, has a configurable image acquisition frame rate, uses a GMSL2 high-speed interface, and supports a maximum extension distance of 15m.

[0027] like Figure 5a As shown, the camera module can be bolted to the top surface of the first housing 3 through the bottom opening 4. Figure 5bAs shown, the camera module can be attached to the top surface of the first housing 3 by adding a magnetic base 5. Those skilled in the art can also use other known methods to individually fix each camera module. Furthermore, each camera module is equipped with an accessory, which can be magnetically connected, for example, by connecting them together through their magnetic mating surfaces, facilitating assembly and disassembly.

[0028] In operation, all camera components 1 are arranged around the vertical axis of agricultural machinery A, with the 4G / 5G communication module 2 located in the central area formed by the camera components 1. Furthermore, the back of the camera module 1 is detachably connected to the outer plane of the 4G / 5G communication module 2 via magnetic attraction. The fields of view of adjacent camera components 1 overlap, forming a seamless 360° surround view coverage around the vertical axis of agricultural machinery A.

[0029] In one embodiment, such as Figure 2a and Figure 2b As shown, the back of the camera module 1 and the outer side of the 4G / 5G communication module 2 are both flat, and the two surfaces are connected together magnetically. This allows each module to fulfill its own functions while maintaining a very compact overall structure.

[0030] In one embodiment, such as Figure 1a , Figure 1b and Figure 2a As shown, there are a total of 6 camera modules 1. The 4G / 5G communication module 2 is hexagonal prism with 6 flat outer surfaces. Each outer surface can magnetically attach to the back of a camera module 1. In this way, the 6 camera modules 1 surround the 4G / 5G communication module 2 in the middle. This method is called the aggregated deployment surround view method, which is suitable for agricultural machinery A with a small chassis.

[0031] Furthermore, among the six camera modules 1, the side shapes of two adjacent camera modules 1 match each other and are fixed together by magnetic attraction surface 11. In this way, the six camera modules 1 can be arranged in a circle around the 4G / 5G communication module 2. The fields of view of two adjacent camera modules 1 overlap, thus forming a 360° concentric panoramic field of view around the axis of the agricultural machinery's height. When the camera components 1 in the aggregated panoramic deployment are arranged around the center of the agricultural machinery chassis, with a total of six camera components, the field of view of each camera component is not less than 60°, forming a continuous and seamless panoramic coverage.

[0032] The six camera modules (1) are trapezoidal cross-section columnar bodies with flat sides and backs. When in use, the camera module 1 has a trapezoidal cross-section in the horizontal direction (referring to the horizontal plane direction in use). This structure allows the sides and backs of two camera modules 1 to fit together, resulting in a compact overall appearance. It also ensures that the fields of view of two adjacent camera modules 1 overlap, forming a 360° concentric panoramic view around the axis of the agricultural machinery's height. Of course, the number of camera modules 1 can be set to other values, as long as a 360° concentric panoramic view of the agricultural machinery is achieved.

[0033] In one embodiment, such as Figure 3a and 3b As shown, two adjacent camera modules 1 are set up independently and separated. This method is called the separate deployment surround view method, which is suitable for agricultural machinery with large chassis.

[0034] Unlike the aggregated surround view deployment method, the discrete surround view deployment method disperses the camera modules 1, such as... Figure 3a and Figure 3b As shown, two camera modules 1 are arranged back-to-back and spaced apart on the top surface of the first housing 3, while the other four camera modules 1 are distributed on the support legs 7 of the chassis 6 of the large-scale agricultural machinery, so as to ensure that the fields of view of two adjacent camera modules 1 overlap with each other, forming a 360° concentric panoramic field of view around the axis of the height direction of the agricultural machinery.

[0035] In one embodiment, such as Figure 4 and Figure 2a As shown, the mountable agricultural inspection device provided in this embodiment of the present invention also includes a data collector. The data collector can be a commercially available ARM Cortex-A53 embedded controller product, which is installed together with the GPS positioning module in the hollow cavity of the first outer shell 3.

[0036] Each module is a standard component or board with standard mounting holes, and is designed to be used in accordance with... Figure 4 The connections shown are integrated and wired. Specifically: the outputs of each camera module 1 and the GPS positioning module are signal-connected to the input of the data acquisition unit. The output of the data acquisition unit is connected to the 4G / 5G communication module 2 via the CAN interface in the interface module 8, or to the communication interface of the agricultural machinery via the Ethernet interface in the interface module 8. In use, the image data of each camera module 1 and the positioning data acquired by the GPS positioning module are collected by the data acquisition unit, and then transmitted by the data acquisition unit to the 4G / 5G communication module 2 via the CAN interface, or to the communication interface of the agricultural machinery via the Ethernet interface, for transmitting the image data collected by the camera module 1 and the positioning data of the GPS positioning module to the agricultural machinery or remote terminal.

[0037] The mountable agricultural inspection device provided in this embodiment of the utility model also includes a power supply module, which is installed inside the first outer shell 3 and supplies power to the electrical equipment through the power supply interface in the interface module 8.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Those skilled in the art should understand that modifications can be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
