Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring devices, and in particular to an online soil and water conservation monitoring device and method based on a 3D camera. Background Art

[0002] Soil and water conservation monitoring refers to the long-term investigation, observation and analysis of the occurrence, development, harm and benefits of soil and water erosion. Through soil and water conservation monitoring, we can find out the types, intensity and distribution characteristics of soil and water erosion, the harm and its impact, the laws of occurrence and development, and the dynamic trend of soil and water erosion. It is of great significance to the macro decision-making of comprehensive soil and water erosion control and ecological environment construction, as well as the scientific, reasonable and systematic deployment of various soil and water conservation measures. Traditional soil and water conservation monitoring requires staff to arrive at the site regularly for manual measurement, which means that a large number of monitoring instruments need to be carried each time, and there are inevitably many uncertain factors in manual measurement, which seriously affect the accuracy of the test results. Summary of the invention

The method is specifically implemented by the following technical solutions:

[0004] The soil and water conservation online monitoring device based on a 3D camera comprises:

[0005] The acquisition module includes a 3D camera and a sensor. The 3D camera is used to acquire images of the water and soil conditions in the monitored area to obtain image information. The sensor is used to acquire soil information.

When acquiring images, the 3D camera simultaneously records the color information and depth information of each point and continuously captures images at a set frame rate.

[0013] A further design of the online monitoring device for soil and water conservation based on a 3D camera is that the data processing module pre-processes the image information by: performing denoising and image enhancement on the received 3D image.

[0014] The further design of the online soil and water conservation monitoring device based on 3D camera is that the three-dimensional model of the data processing generation module is specifically: point cloud data is generated according to the depth information and color information collected by the 3D camera, and a three-dimensional model of the monitored area is generated from the point cloud data through a three-dimensional reconstruction algorithm, and the topography and soil and water conditions of the monitored location are fed back through the three-dimensional model.

[0016] A further design of the 3D camera-based online soil and water conservation monitoring device is that the data processing module generates soil and water conservation information: the terrain features, soil erosion conditions, and vegetation coverage and growth conditions are integrated and processed to form a soil and water conservation information data set, and the soil and water conservation information of the monitored location is obtained by processing the soil and water conservation information data set.

[0017] The further design of the soil and water conservation online monitoring device based on the 3D camera is that the soil and water conservation information data set is processed specifically as follows:

[0033] The technical solution of the present invention is described in detail below.

[0034] like Figure 1 As shown, the embodiment of the present invention discloses an online monitoring device for soil and water conservation based on a 3D camera, which is mainly composed of: a collection module 101, a data processing module 102, a communication module 103, an early warning module 106, a remote server 104 and a user terminal 105. Among them, the collection module 101 includes a 3D camera and a sensor, and the 3D camera is used to collect images of the soil and water conditions in the monitored area to obtain image information; and the sensor is used to collect soil information. The data processing module 102 receives the image information collected by the 3D camera, pre-processes the image information, and generates a three-dimensional model of the monitored area based on a three-dimensional reconstruction algorithm, and obtains the soil and water conservation information of the monitored position by extracting and analyzing the features of the three-dimensional model. The communication module 103 is connected to the data processing module, and is used to transmit the processed data to the remote server 104 and the user terminal 105 in real time, so that the remote server and the user terminal can grasp the soil and water conservation conditions of the monitored position in real time. The early warning module 106 is used to judge the real-time data according to the preset early warning threshold, and send an early warning signal to the remote server and the user terminal through the communication module when the data is abnormal. The remote server 104 and the user terminal 105 are used to receive the processed information and transmit control commands to control the 3D camera to perform actions.

[0035] Furthermore, the 3D camera of this embodiment collects images of water and soil information at the monitored location by the following method:

[0036] Startup and positioning: After determining the water and soil areas that need to be monitored, install the 3D camera in an appropriate position to ensure that the 3D camera can fully cover the target monitoring area, and adjust the angle and focal length of the 3D camera to obtain the best shooting field of view and image clarity.

[0037] Image acquisition: The 3D camera uses its optical structure or methods, such as structured light, time-of-flight (TOF) or binocular stereo vision, to capture the depth information of the shooting space and then measure the distance between the object and the camera. When collecting images, the 3D camera records the color information and depth information of each point at the same time. In this way, each image point has not only an RGB color value, but also a depth value indicating its distance from the camera. Images are captured continuously at a set frame rate to ensure that the dynamic changes of water and soil can be monitored in real time, and the frame rate of the camera can be adjusted according to actual needs to meet the requirements of different monitoring accuracies.

[0038] Furthermore, the process of the data processing module obtaining the soil and water conservation information of the monitored location according to the image information collected by the 3D camera specifically includes:

[0039] Image preprocessing: First, the received 3D image is denoised to reduce noise and artifacts in the image. This can be achieved through image filtering techniques, such as Gaussian filtering or median filtering, to improve the quality and accuracy of the image. Next, image enhancement operations are performed, such as contrast enhancement or sharpening, to highlight the key features and details in the image for subsequent analysis and processing.

[0040] 3D reconstruction and model generation: The depth information and color information collected by the 3D camera are combined to generate point cloud data, which includes the 3D coordinates and color information of the monitored location. Using the point cloud data, a 3D reconstruction algorithm (such as Poisson reconstruction or Delaunay triangulation) is used to generate a 3D model of the monitored area, which reflects the topography and soil and water conditions of the monitored location.

[0041] Feature extraction and analysis: Extract key terrain features from the 3D model (terrain features include slope, aspect, and elevation, etc.), combine terrain features and soil information (soil information includes erosion type, erosion range, etc.) to analyze soil erosion conditions. For example, by calculating indicators such as slope changes and elevation differences, the rate and extent of soil erosion can be estimated. Use the color information and 3D structure information in the image to analyze vegetation coverage and growth. Vegetation is one of the important factors in soil and water conservation, and its coverage and growth directly affect the soil protection effect.

[0042] Soil and water conservation information generation: The terrain features, soil erosion conditions, and vegetation coverage and growth conditions are integrated and processed to form a soil and water conservation information data set, and the soil and water conservation conditions of the monitored location are obtained by processing the soil and water conservation information data set.

[0043] Furthermore, the process of obtaining the soil and water conservation situation of the monitored location by processing the soil and water conservation information data set is specifically as follows:

[0044] Data integration: Unify terrain feature data, soil erosion status data, and vegetation coverage and growth status data into the same coordinate system, use the same spatial resolution, and normalize the data.

[0045] Data fusion and overlay: The unified terrain feature data, soil erosion status data, and vegetation coverage and growth status data are overlaid and analyzed on the GIS platform. The spatial analysis tools on the GIS platform are used to perform overlay analysis and buffer zone analysis to identify the spatial relationship between different factors.

[0046] Data processing and analysis: Perform descriptive statistics on various types of data, obtain the distribution and characteristics of the data, and conduct correlation analysis between topography, soil erosion and vegetation cover.

[0047] Model construction: The correlation between topography, soil erosion and vegetation cover is used to establish a prediction model to evaluate the impact of different factors on soil and water conservation capacity. Based on the model prediction results, the key areas and sensitive factors for soil and water conservation capacity assessment are identified.

[0048] Data verification and model optimization: By comparing with the ground-truth data, the accuracy of key areas and sensitive factors is verified, and the prediction model is dynamically adjusted and optimized according to the verification results.

[0049] Obtaining soil and water conservation status: Input the data collected by the 3D camera in real time into the optimized dynamic model to predict the soil and water conservation status and obtain soil and water conservation status information.

[0050] Accordingly, this embodiment also discloses a method for online monitoring of soil and water conservation based on a 3D camera, comprising the following steps:

[0051] S1) Use a 3D camera to collect images of the water and soil conditions at the monitored location.

[0052] S2) receiving image information collected by a 3D camera, preprocessing the image information, generating a three-dimensional model of the monitored area based on a three-dimensional reconstruction algorithm, and obtaining soil and water conservation information of the monitored location by extracting and analyzing features of the three-dimensional model.

[0053] S3) The processed data is transmitted to the remote server and the user terminal in real time, so that the remote server and the user terminal can grasp the soil and water conservation situation of the monitored location.

[0054] S4) judging the real-time data according to a preset warning threshold, and sending a warning signal to the remote server and the user terminal through the communication module when the data is abnormal.

[0055] In summary, the system and method described in the present application collects the water and soil conditions of the monitored location in real time through a 3D camera, and processes the image information accordingly to obtain soil and water conservation information of the monitored location. It can monitor soil and water loss in real time and accurately, and perform data analysis and early warning. It has a high degree of automation and can be widely used in soil and water conservation monitoring work in different types of land and scenes.
