[0001] The present invention relates to the field of optical observation, and in particular, to an optical observation apparatus for a water body and a method of evaluating quality of the water body with the same.

METHOD OF EVALUATING QUALITY OF GLOBAL WATER BODY WITH THE SAME
TECHNICAL FIELD
[0001] The present invention relates to the field of optical observation, and in particular, to an optical observation apparatus for a water body and a method of evaluating quality of the water body with the same.
BACKGROUND
[0002] Ocean science has developed substantially during the second half of the 20th century, and it is gradually realized that an ocean plays a vital regulatory role in a sustainable development of a global environment and a human society. Research on an ocean water body is a basis for studying an ocean environment, and occupies an important position in ocean current surveillance, weather forecast, disaster prevention and mitigation, environmental governance and polar scientific investigation. Currently, the ocean water body is researched deeply at home and abroad. Ocean optical research is mainly on optical properties of the ocean and a law of propagation of light in the ocean, and depends on basic data which are mainly spectral data of the ocean water body obtained with field and laboratory measurement methods, for example, research on a spectral radiation field which is generated by a radiation transfer process and located upwards from a surface of the ocean after sunlight enters the ocean.
[0003] In a prior art, the basic data on which the optical research on the water body, such as the ocean, or the like, relies are basically obtained by a professional technician of a professional technical institution operating a professional observation apparatus to observe in the field or in a laboratory. In this process, the observation apparatus tends to have a complex structure and a high operation requirement, and the technician may use the observation apparatus correctly to obtain the effective observation data after trained professionally. Currently, there are various types of apparatuses generally recognized worldwide to be able to observe ocean optical data effectively, for example, the optical observation apparatus currently available on the market, such as Seabird, TriOS or Water Insights, or the like. These observation apparatuses have different portable degrees and operation difficulties, but are almost bulky or heavy, and require special training for a user before put into practical observation application. However, the global ocean water body has a huge scale, and some optical changes occur very rapidly. A very limited number of ocean optical observation institutions as well as personnel and apparatuses thereof are not enough to meet a growing observational demand at all, which limits collection and utilization of the ocean optical observation data to a great extent.
[0004] With a development of an information technology and popularization of intelligent equipment, the period of big data has surged, and data collection and big data analysis implemented with the intelligent equipment and the information technology have penetrated into all aspects of people's lives and production. The closer a field is to people's lives, the more mature the accumulation of the intelligent equipment and the big data is, which in turn facilitates people's lives in this field. From the perspective of overall ecology of the earth, as a very important ecosystem on the earth, the water body, such as the ocean, or the like, actually, is closely related to human survival and development all the time. With awakening of ecological consciousness, common people have increasingly sought to learn, pay attention to and even research various water bodies around them, and the professional institution increasingly demands synchronicity and systematicness of global water body observations. Therefore, how to use the network information technology and the intelligent equipment effectively to enable big data analysis to fully penetrate the field of optical observation of the water body has become an important problem of current optical observation of the water body. The first task to solve the problem is to solve the problem of miniaturization and intelligence of the observation apparatus. In addition, the use of the small intelligent observation apparatus to establish new water body evaluation system and mode may also fully meet the need of water body quality evaluation.
SUMMARY
SUMMARY
[0005] In view of the above-mentioned technical background, a primary object of the present invention is to provide a miniaturized and intelligent optical observation apparatus for a water body, which is, for a non-professional person, not only portable enough, but also easy enough to mount and operate, which is more important, and optical observation data of the water body may be collected effectively without training, which will break the existing limitation that a professional person may observe the optical data of the water body only after trained professionally, such that the common non-professional person at a waterside or in a water area may complete observation and provide data at any time and place.
[0006] The above-mentioned object of the present invention is achieved with the following technical solution.
[0007] Firstly, a miniaturized and intelligent optical observation apparatus for a water body is provided, which includes an observer, a mobile intelligent terminal and a handheld self-stabilization holder;
[0008] the handheld self-stabilization holder is provided with a handheld grip at one end and a three-axis stabilizer at the other end, and a heading axis of the three-axis stabilizer is fixedly connected with the handheld grip by a length-adjustable connecting rod; a pitch axis of the three-axis stabilizer is provided with a first clamp for clamping the observer; the handheld grip is provided with a second clamp for clamping the mobile intelligent terminal;
[0009] the observer is clamped in the first clamp, and includes a rigid rectangular parallelepiped casing which has two adjacent surfaces each provided with a rigid observation tube fixedly connected with the rectangular parallelepiped casing; one of the two surfaces is provided with two radiance observation tubes symmetrically, each radiance observation tube forms an included angle of 40 with the surface at which it is located, and the two radiance observation tubes form an included angle of 1000, and are each provided therein with a radiance radiometer; the other surface is perpendicularly provided with an irradiance observation tube provided therein with an irradiance radiometer; a circuit board and a battery are further provided in the rectangular parallelepiped casing; the circuit board only includes a radiometer driving module and a data wireless transmission module; the radiometer driving module is electrically connected with the irradiance radiometer and the radiance radiometer respectively, and configured to convert optical signals collected by the radiometers into digital signals; the data wireless transmission module is connected with the radiometer driving module electrically, and configured to transmit the digital signals to the mobile intelligent terminal wirelessly; the battery is connected with the circuit board and supplies power thereto;
100101 the mobile intelligent terminal is clamped in the second clamp, coupled with the observer and the three-axis stabilizer wirelessly, and has a built-in observation application which is used to set a data collection parameter and monitor adjustment of an attitude of the three-axis stabilizer in real time, and meanwhile to receive, save and display data from the observer, analyze the data and/or share or send an analysis result to the outside.
100111 In the solution of the present invention, the mobile intelligent terminal may be configured as any existing common movable intelligent equipment, usually has an ability to access the Internet, and may carry various operating systems for executing the observation application. The mobile intelligent terminal applicable in the solution of the present invention may be configured as a handheld mobile intelligent terminal, a vehicle-mounted mobile intelligent terminal or a wearable intelligent apparatus, such as a smart phone, a tablet computer, a PDA
intelligent terminal or an intelligent watch, or the like, preferably the smart phone or the tablet computer in the present invention.
100121 In the solution of the present invention, the three-axis stabilizer is provided therein with an IMU feedback system consisted of a three-axis gyroscope and a three-axis acceleration sensor and a servo motor, and the observer fixed at the pitch axis may be always fixed at a certain observation angle according to a preset parameter.
[0013] In a preferred solution of the present invention, in order to further miniaturize an observation unit, with respect to the pitch axis of the three-axis stabilizer, the two radiance observation tubes and the irradiance observation tube are located at the same vertical plane.
[0014] In the solution of the present invention, the length-adjustable connecting rod of the handheld self-stabilization holder may be configured as various existing connecting rods, for example, a telescopic rod or a folding rod, preferably a multi-section telescopic rod.
[0015] In the solution of the present invention, the first clamp is configured as a clamp matched with the rectangular parallelepiped casing in shape and having an internal space of a flat rectangular shape, and a long side thereof is parallel to the pitch axis of the three-axis stabilizer.
[0016] In a preferred solution of the present invention, a control button is further provided at the handheld grip of the handheld self-stabilization holder, connected with the observer wirelessly, and configured to complete simple operations, such as starting or stopping observation data collection, or the like, and may serve as a supplement to control by the mobile intelligent terminal.
[0017] In a preferred solution of the present invention, the mobile intelligent terminal is further provided therein with an electronic clock module, a satellite positioning module, a camera module and a storage apparatus, and the storage apparatus stores the application which performs the following steps continuously:
[0018] 1) retrieving time data of the electronic clock module and position data of the satellite positioning module, and calculating a solar azimuth angle at that time and place according to the time data and the position data;
[0019] 2) acquiring attitude data of the three-axis stabilizer by means of wireless connection between the mobile intelligent terminal and the three-axis stabilizer;
[0020] 3) generating an attitude adjustment parameter by comparing the solar azimuth angle in 1) with the attitude data of the three-axis stabilizer in 2), and sending the attitude adjustment parameter to the three-axis stabilizer by means of the wireless connection between the mobile intelligent terminal and the three-axis stabilizer, so as to drive the servo motor of the three-axis stabilizer to adjust the attitude of the three-axis stabilizer, such that the observer always keeps an observation geometry of 40 to 135 precisely;
[0021] 4) receiving the observation data of the observer continuously by means of the wireless connection between the mobile intelligent terminal and the observer, and calculating a remote sensing reflectance Rrs of the water body based on the observation data;
[0022] 5) calling a camera function of the mobile intelligent terminal to shoot a synchronous image, and uploading the remote sensing reflectance Rrs data, the synchronous image, the time data and the position data to a data center server via the Internet for modeling;
and [0023] 6) downloading the data from the data center server, forming a visual analysis result, and displaying the result by means of human-computer interaction.
[0024] Compared with the prior art, the solution of the present invention makes full use of functions of the mobile intelligent terminal, such as time, positioning, data processing, network connection, human-computer interaction, or the like, and most functions, such as parameter setting, adjustment of the observation geometry, data processing, or the like, which are required to be completed in existing spectral field observation of the water body, are performed by the mobile intelligent terminal using application software, thus reducing a scale of the circuit board required by the observer greatly, reducing a volume of the observer significantly, and enabling the observer to be matched with the conventional handheld self-stabilization holder in volume and weight, which improves a portability of the observer remarkably. At the same time, it is more important that a user of the observation apparatus according to the present invention is not required to master apparatus parameters, an operation specification, or the like, and all the observation parameters are set in advance by the application installed in the mobile intelligent terminal, and are adjusted automatically by the three-axis stabilizer according to the adjustment data provided by the application. The user of the apparatus is only required to hold the optical observation apparatus for the water body according to the present invention with the hand at the waterside and keep it turned on, with simplicity close to a conventional daily video shooting action at the waterside, which will greatly lower a threshold for using the observation apparatus according to the present invention, and enables the non-professional person to complete effective optical observation of the water body in a daily state without any obstacle, thereby implementing big data accumulation of the optical observation of the global water body.
[0025] In addition, in the present invention, the irradiance radiometer and the radiance radiometer are fixedly mounted at the rigid rectangular parallelepiped casing at the specific angle, the rectangular parallelepiped casing is very suitable for being fixed by the clamp, and a surface of the rectangular parallelepiped casing clamped by the clamp may be kept fixed at the same straight line as the pitch axis of the three-axis stabilizer, or parallel thereto, such that each observer fixed at the rectangular parallelepiped casing has the attitude fixed naturally relative to the pitch axis of the three-axis stabilizer, thus greatly simplifying disassembly and assembly of the observer and attitude adjustment of the radiometer.
[0026] In short, the optical observation apparatus for the water body according to the present invention may be configured for spectral observation of the water body, such as a river, a lake, coastal water, an ocean, or the like, and has outstanding advantages of a compact structure, a small volume, a light weight, portability, simple mounting, simple and convenient operation, or the like.
[0027] On this basis, another object of the present invention is to provide a method of evaluating quality of a water body with the optical observation apparatus for the water body. The object is achieved with the following technical solution.
[0028] Firstly, there is provided a method of evaluating quality of a water body with the optical observation apparatus for the water body, which is written as a first method, including:
[0029] a. building a data center server which is provided with at least a data receiving module, a data analysis module and a data publishing module;

[0045] In each method according to the present invention, after the mobile intelligent terminal obtains the water-body quality characterization data, a formatted or visual water-body quality evaluation result report is further formed by the embedded application, and displayed by an interactive page.
[0046] With the above-mentioned method according to the present invention, on the one hand, the data of the water bodies at different positions of the world may be acquired at any time and place with the portability of the optical observation apparatus for the water body according to the present invention, instead of requiring a professional scientific researcher to collect and obtain a relatively limited number of data by observation in a limited time at a limited place, such that the optical observation data of the global water body may be enriched greatly, and meanwhile the observation data are acquired by similar apparatuses based on the same standard, which may promote resource sharing and analysis utilization of the global observation data greatly; on the other hand, when the data of the global water body are accumulated to a certain degree, and the public would like to learn the quality of any water body, the public may obtain a corresponding evaluation result immediately only by uploading information of the position and/or the real-scene image of the water body required to be learned to the data center server, regardless of the position of the public at the water body, which not only reduces a research cost of the researcher in the art significantly, but also facilitates knowledge of the general public to the quality of the water body greatly.
