Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Combine the following Figure 1-Figure 5 The invention describes the satellite remote sensing water body product inspection method and system.

[0044] Specifically, the present invention provides a satellite remote sensing water product inspection system, referring to Figure 1 , Figure 1 It is a structural schematic diagram of the satellite remote sensing water product inspection system provided by the present invention.

[0045] The satellite remote sensing water product inspection system provided in the embodiment of the present invention comprises: a spectral pod unit 10, a water quality monitoring unit 20, a measurement control unit 30 and a display processing platform unit 40;

[0046] The spectral pod unit 10 is used to measure spectral data and collect image data of a set target, and send the spectral data and image data to the measurement control unit 30;

[0047] Specifically, when the satellite remote sensing water product inspection system is in working condition, the spectral pod unit 10 will automatically measure the spectral data and collect the image data of the set target, and send the spectral data and image data to the measurement control unit 30 by wired or wireless means. Among them, the spectral data includes the incident irradiance of the water surface, the radiance of the sky and the radiance of the water surface. It can be understood that the irradiance refers to the radiation flux received per unit area, which is related to the distance between the detector and the light source, and has nothing to do with the azimuth and the observation angle; the radiance refers to the radiation flux per unit projection area and per unit solid angle, which varies with the wavelength and has directionality, and is related to the azimuth and the observation angle; the incident irradiance of the water surface refers to the irradiance generated by the sunlight radiation incident on the waterside, which usually includes the sum of the direct sunlight and the diffuse sky light irradiance.

[0048] The water quality monitoring unit 20 is used to measure water quality parameters and send the water quality parameters to the measurement control unit 30;

[0049] Specifically, when the satellite remote sensing water product inspection system is in working condition, the water quality measurement unit automatically measures the water quality at the system location. For example, the water quality at the system location can be measured by electrochemical methods, optical methods, biological methods, etc., and the water quality parameters are determined based on the water quality conditions. The water quality parameters include pH value, conductivity, dissolved oxygen, turbidity, and temperature, etc. Finally, the water quality parameters are sent to the measurement control unit 30 via wired or wireless means.

[0050] The measurement control unit 30 is used to receive the spectral data and image data sent by the spectral pod unit 10, and receive the water quality parameters sent by the water quality monitoring unit 20, and send the spectral data, image data and water quality parameters to the display processing platform unit 40;

[0051] Specifically, when the measurement control unit 30 receives the spectral data and image data sent by the spectral pod unit 10 and the water quality parameters sent by the water quality monitoring unit 20 , it packages the spectral data, image data and water quality parameters, and then sends the packaged data to the display processing platform unit 40 .

[0052] The display processing platform unit 40 is used to receive the spectral data, image data and water quality parameters sent by the measurement control unit 30, and to verify the measurement data of the satellite remote sensing water product according to the spectral data, image data and water quality parameters.

[0053] Specifically, when the display processing platform unit 40 receives the packaged data sent by the measurement control unit 30, it parses the packaged data to obtain spectral data, image data and water quality parameters, and then uses the image data to judge the reliability of the spectral data, wherein the image data is used to monitor interference such as flares and waves on the water surface to eliminate abnormal data caused by flares and waves, and combines these interference information to determine whether the measured spectral data is reliable. If reliable, the spectral data and water quality parameters are scaled, and the scaled data are compared with the measurement data of the satellite remote sensing water product to verify the authenticity of the measurement data of the satellite remote sensing water product.

[0054] The satellite remote sensing water product inspection system provided in the embodiment of the present invention collects spectral data and image data through the spectral pod unit 10, and collects water quality parameters through the water quality monitoring unit 20, and inspects the measurement data of the satellite remote sensing water product based on the spectral data, image data and water quality parameters, thereby improving the inspection efficiency and inspection accuracy of the measurement data of the remote sensing water product.

[0055] Further, the spectroscopic pod unit 10 includes a first spectrometer, a second spectrometer and a third spectrometer;

[0056] A first spectrometer is used to measure the incident irradiance on the water surface;

[0057] a second spectrometer to measure sky radiance;

[0058] The third spectrometer is used to measure the radiance of the water surface;

[0059] The spectral data include incident irradiance on the water surface, sky radiance and water surface radiance.

[0060] Specifically, the spectral pod unit 10 includes a first spectrometer, a second spectrometer and a third spectrometer, wherein the spectrometer is a device that uses a photomultiplier tube or other light detector to measure the intensity of different wavelength positions of a spectrum line. The first spectrometer is installed vertically to measure the incident irradiance of the water surface; the second spectrometer is installed at a certain angle to the zenith angle to measure the radiance of the sky; the third spectrometer is installed at a certain angle to the nadir angle to measure the radiance of the water surface. Among them, the zenith angle refers to the angle between the incident direction of the light and the zenith direction; the nadir angle refers to the angle between the incident direction of the light and the nadir direction.

[0061] This embodiment improves the measurement efficiency of spectral data by setting up multiple spectrometers to measure different spectral data, thereby improving the inspection efficiency of measurement data of remote sensing water products.

[0062] Further, the spectral pod unit 10 also includes a first camera, a second camera and a third camera;

[0063] The first camera is arranged in parallel with the second spectrometer to collect image data of the sky;

[0064] The second camera is arranged in parallel with the third spectrometer to collect image data of the water surface;

[0065] A third camera is used to collect image data of the sun;

[0066] Wherein, the set target includes the sky, the water surface and the sun.

[0067] Specifically, the spectral pod unit 10 also includes a first camera, a second camera and a third camera. The first camera and the second spectrometer are fixedly installed in parallel, and are used to collect image data of the sky, and then monitor changes in the sky based on the image data of the sky; the second camera and the third spectrometer are installed in parallel, and are used to collect image data of the water surface, and then monitor the water surface conditions based on the image data of the water surface; the third camera is used to collect image data of the sun, and then track the position of the sun based on the image data of the sun, so that the instrument measurement plane and the sun incidence plane are always at a fixed angle.

[0068] This embodiment improves the efficiency of collecting image data by setting cameras to collect different image data, thereby improving the efficiency of checking the measurement data of remote sensing water products.

[0069] Furthermore, the spectral pod unit 10 also includes a positioning module for recording the position information and attitude information of the spectral pod unit 10. Specifically, the positioning module refers to a GPS / IMU module for recording the position and attitude information of the spectral pod unit 10, wherein the Global Positioning System (GPS) is used to record the position of the spectral pod unit 10, including position information such as longitude and latitude, and the Inertial Measurement Unit (IMU) is used to record the attitude information of the spectral pod unit 10. Based on this, it can be ensured that the spectral pod unit 10 collects data at a preset position and preset attitude, thereby improving the accuracy of the collected measurement data.

[0070] Furthermore, the measurement control unit 30 is also used to receive the control instructions sent by the display processing platform unit 40, and control the measurement frequency and measurement parameters of the spectrum pod unit 10 and the water quality monitoring unit 20 according to the control instructions;

[0071] The measurement control unit 30 is further used to determine the position information of the sun according to the position information and attitude information of the spectrum pod unit 10, and adjust the angle of the spectrum pod unit 10 according to the position information of the sun and the image data.

[0072] Specifically, the display processing platform unit 40 is a main control unit that can set the measurement frequency and measurement parameters of the spectral pod unit 10 and the water quality monitoring unit 20. The display processing platform unit 40 sends a control instruction to the measurement control unit 30. After the measurement control unit 30 receives the control instruction, it controls the measurement frequency and measurement parameters of the spectral pod unit 10 and the water quality monitoring unit 20 according to the control instruction.

[0073] After determining the position information and attitude information of the spectral pod unit 10, the measurement control unit 30 determines the position information of the sun based on the position information and attitude information, and then adjusts the angle of the spectral pod unit 10 according to the position information and image data of the sun to meet the measurement conditions, wherein the position information includes information such as longitude and latitude information. For example, position information such as the solar azimuth angle and the solar hour angle can be determined based on the position information and attitude information, wherein the change of the declination angle δ in a year is calculated using the following formula:

[0074] δ=23.45*sin[360*(284+n) / 365];

[0075] The solar azimuth angle A can be calculated by the following formula, where the final variables include local time, local latitude information, and the sun's ecliptic longitude coordinates, etc.

[0076] Formula 1:

[0077] Among them, h⊙sun altitude angle; tsun hour angle; δsun declination; local latitude;

[0078] Formula 2:

[0079] Among them, A is the solar azimuth; h⊙ is the solar altitude; δ is the solar declination; Local latitude.

[0080] The solar hour angle can be calculated from the local time, where the solar hour angle is approximately zero at noon, negative in the morning, and positive in the afternoon. It is approximately -90° at sunrise and approximately 90° at sunset. The calculation formula for the solar hour angle is:

[0081] Solar hour angle t = (real time (called True Time) - 12) * 15° = (common time (called MeanTime) - mean time difference (equation of time) - 12) * 15°;

[0082] Among them, the value of the equation of time changes periodically throughout the year.

[0083] This embodiment improves the collection efficiency of measurement data by controlling the measurement frequency and measurement parameters of the spectral pod unit 10 and the water quality monitoring unit 20, thereby improving the inspection efficiency of the measurement data of the remote sensing water product. At the same time, the angle of the spectral pod unit 10 is adjusted according to the position information of the sun and the image data to meet the measurement conditions, thereby improving the accuracy of data collection.

[0084] Furthermore, the satellite remote sensing water product inspection system further includes a fixing unit 50, a supporting unit 60, a posture stabilizing unit 70 and a power supply unit 80;

[0085] A fixing unit 50, used for fixing the inspection device;

[0086] A support unit 60, used to support the inspection device;

[0087] An attitude stabilization unit 70, used to stabilize the spectrum pod unit 10;

[0088] The power supply unit 80 is used to supply power to the inspection device.

[0089] Specifically, the satellite remote sensing water product inspection system also includes a fixing unit 50, a supporting unit 60, an attitude stabilization unit 70 and a power supply unit 80, wherein the fixing unit 50 is used to fix the inspection equipment, that is, to fix the entire system; the supporting unit 60 can be an unmanned ship or a buoy or other supporting object, used to support the inspection equipment; the attitude stabilization unit 70 is composed of a two-axis or three-axis gimbal to ensure that the connected spectral pod unit 10 works vertically; the power supply unit 80 is used to power the inspection equipment, for example, the power supply unit 80 supplies power to various sensors in the inspection equipment through the measurement control unit 30.

[0090] This embodiment fixes and supports the inspection equipment through the fixing unit 50 and the supporting unit 60, stabilizes the spectral pod unit 10 through the posture stabilization unit 70, and supplies power to the inspection equipment through the power supply unit 80, thereby ensuring that the inspection equipment can work normally and improving the accuracy of data collected by each unit in the inspection equipment.

[0091] Further, refer to Figure 2 , Figure 2 It is a schematic diagram of the framework of the satellite remote sensing water product inspection system provided by the present invention.

[0092] The satellite remote sensing water product inspection system includes a fixing unit 50 , a spectral pod unit 10 , a measurement control unit 30 , a support unit 60 , a water quality monitoring unit 20 , a display processing platform unit 40 , a posture stabilization unit 70 and a power supply unit 80 .

[0093] Specifically, the fixing unit 50 is connected to the supporting unit 60 for fixing the entire system, the fixing unit 50 is connected to the posture stabilization unit 70, and the posture stabilization unit 70 is connected to the spectral pod unit 10; the measurement control unit 30 is connected to the posture stabilization unit 70 for controlling the spectral pod unit 10 to remain vertical, the measurement control unit 30 is connected to the spectral pod unit 10 for controlling the operation of the spectrometer and camera of the spectral pod unit 10; the measurement control unit 30 is connected to the water quality monitoring unit 20 for controlling the measurement parameters and the measurement frequency, and the measurement control unit 30 is connected to the display processing platform unit 40 to send the collected various data to the display processing platform unit 40.

[0094] Under the command control of the display processing platform unit 40, the spectral pod unit 10 and the water quality monitoring unit 20 respectively record various types of spectral data, image data, and water quality data, and send the collected data to the display processing platform unit 40 in a wired or wireless manner through the measurement control unit 30. The display processing platform unit 40 calculates the water body reflectance based on the data, performs scale conversion, and compares the authenticity with the satellite remote sensing water body products.

[0095] This embodiment collects spectral data and image data through the spectral pod unit 10, and collects water quality parameters through the water quality monitoring unit 20, and verifies the measurement data of the satellite remote sensing water product based on the spectral data, image data and water quality parameters, thereby improving the verification efficiency and verification accuracy of the measurement data of the remote sensing water product.

[0096] refer to Figure 3 , Figure 3 : is a flow chart of the satellite remote sensing water product inspection method provided by the present invention. The satellite remote sensing water product inspection method provided by an embodiment of the present invention is applied to the satellite remote sensing water product inspection system provided by the above embodiment, including:

[0097] Step S10, collecting the spectral data and the image data through the spectral pod unit, and collecting the water quality parameters through the water quality monitoring unit;

[0098] Step S20, if it is determined according to the image data that the spectral data meets the set condition, the spectral data and the water quality parameter are scaled;

[0099] Step S30, verifying the measurement data of the satellite remote sensing water product according to the scale-converted data.

[0100] In this embodiment, under the instruction control of the display processing platform unit, the spectral pod unit and the water quality monitoring unit respectively collect various types of spectral data, image data, and water quality data, and then send the collected data to the display processing platform unit in a wired or wireless manner through the measurement control unit. The display processing platform unit calculates the water body reflectance based on the data, performs scale conversion, and compares the authenticity with the satellite remote sensing water body product. For example, according to the image data, it is determined that the spectral data meets the set conditions, then the spectral data and water quality parameters are scaled, that is, the image data is used to judge the reliability of the spectral data, wherein the image data is used to monitor interference such as flares and waves on the water body surface to eliminate abnormal data caused by flares and waves. Combined with these interference information, it is determined whether the measured spectral data is reliable. If it is reliable, it is determined that the conditions are met. At this time, the spectral data and water quality parameters are scaled, and the measurement data of the satellite remote sensing water body product is checked according to the scale-converted data.

[0101] It is understandable that different resolution data reflect inconsistent landmark information. Among them, high-resolution remote sensing image data can represent the detailed information of the surface, but lacks macro information, while medium and low resolution remote sensing image data can reflect data information from a macro perspective, but is not conducive to expressing the detailed information of the surface, and thus is not conducive to reflecting the real situation. Scale conversion in remote sensing refers to the process of converting data from one horizontal resolution to another. Scale conversion implies changes in the amount of information and is a change in the distribution of spatial patterns. In general, scale conversion can be divided into scale push-up and scale push-down. Scale push-up is the process of converting relatively accurate observation results in a smaller scale range to a larger scale range. The resolution is reduced by downsampling. The scale push-up of remote sensing data is essentially a synthesis of geographic information, which is visually manifested as the gradual smoothing and blurring of geographic information within the same field of view. The scale push-up process is also a smoothing and blurring process. After the remote sensing data is Gaussian blurred and downsampled by the Gaussian pyramid method, the spatial resolution is reduced, and the detailed features are smoothed and gradually discarded, thereby achieving the purpose of integrating geographic information and scale push-up, and also making the image size meet the requirements of the display area.

[0102] The ideal scale-up conversion is to retain the detail information after conversion and have the macro information after conversion. However, due to the existence of surface heterogeneity images, the types of objects corresponding to the same pixel in images with different resolutions are inconsistent. In low-resolution images, a pixel may have several types of objects, that is, mixed pixels. The lower the resolution, the less detailed information, the greater the degree of mixed pixels, and the influence of mixed pixels on scale conversion is relatively large, which can easily cause great uncertainty.

[0103] In the embodiment of the present invention, the scale conversion can be realized based on the pixel method, which mainly includes mathematical statistics, image fusion and classification conversion. For example, Figure 4 , using the bilinear interpolation resampling method to represent:

[0104] Calculation formula based on the (x, y) coordinates of different pixels:

[0105] W 11 =W(x1)*W(y1);

[0106] W 12 =W(x1)*W(y2);

[0107] W 21 =W(x2)*W(y1);

[0108] W 22 =W(x2)*W(y2);

[0109] Among them, W(x1)=1-△x, W(x2)=△x, W(y1)=1-△y, W(y2)=△y;

[0110] The value of the interpolation point I(p) can be obtained as follows:

[0111] I(p)=I 11 W 11 +I 12 W 12 +I 21 W 21 +I 22 W 22

[0112] The satellite remote sensing water product inspection method provided in this embodiment collects spectral data and image data through a spectral pod unit, and collects water quality parameters through a water quality monitoring unit; if it is determined based on the image data that the spectral data meets the set conditions, the spectral data and water quality parameters are scaled; the measurement data of the satellite remote sensing water product is inspected based on the scale-converted data, thereby improving the inspection efficiency and inspection accuracy of the measurement data of the remote sensing water product.
