[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] The visual control system for surveying and mapping accuracy based on remote sensing mapping terminals includes a control platform, which is connected to:

[0008] The satellite surveying and mapping impact analysis unit is used to mark the satellite cooperation terminal in the remote sensing surveying and mapping terminal as a surveying and mapping satellite terminal, collect clock error data and numerical deviation data at the same time, and infer whether the surveying and mapping impact analysis of the current surveying and mapping satellite terminal is abnormal based on data analysis, so as to facilitate regional surveying and mapping regulation;

[0009] The mapping scheme adaptive adjustment unit is used to divide the real-time mapping area into a number of equal-area sub-areas, and set the preset point planning according to the current distribution points; collect the mapping scheme adjustment information, and obtain the adjustment coefficient of the preset point in the preset point planning, infer whether the current preset point needs to be adjusted through adjustment coefficient comparison, and obtain the confirmed point planning through analysis and adjustment;

[0010] The synchronous ring detection unit is used to detect the synchronous ring mapping, collect the horizontal overlapping synchronization information and the vertical overlapping synchronization information, infer whether there is a deviation in the synchronous ring mapping based on the information analysis, and perform mapping regulation;

[0011] The asynchronous ring detection unit is used to detect asynchronous ring surveying and mapping, collect asynchronous single frame loss data and asynchronous multiple deviation data, infer that there are deviations in the mobile subject surveying and mapping of asynchronous ring surveying, and perform surveying and mapping regulation.

[0012] As a preferred embodiment of the present invention, the clock error data and the digital deviation data are respectively the satellite clock error generated by the atomic clock time installed on the surveying and mapping satellite and the standard time, and the deviation span value of the amount of data transmitted under the current surveying and mapping satellite signal fluctuation within the satellite clock error.

[0013] As a preferred embodiment of the present invention, if the clock error data exceeds the satellite clock error threshold, or the digital deviation data exceeds the deviation span threshold, a surveying and mapping impact signal is generated; if the clock error data does not exceed the satellite clock error threshold, and the digital deviation data does not exceed the deviation span threshold, a surveying and mapping normal signal is generated.

[0014] As a preferred embodiment of the present invention, the surveying and mapping scheme adjustment information includes the maximum coverage area of ​​the surveying and mapping range corresponding to a single monitoring station in the same type of sub-area in the preset point planning, the maximum deviation value of the coverage area corresponding to different monitoring stations when there are multiple monitoring stations covering the same type of sub-area, and the deviation value of the mean value of the surveying and mapping image clarity in the coverage range of the same monitoring station in different types of sub-areas in the preset point planning.

[0015] As a preferred embodiment of the present invention, if the adjustment coefficient of the preset point in the preset point planning exceeds the adjustment coefficient threshold, an adaptive adjustment signal is generated; if the adjustment coefficient of the preset point in the preset point planning does not exceed the adjustment coefficient threshold, an adaptive qualified signal is generated.

[0016] As a preferred implementation of the present invention, the horizontal overlapping synchronization information and the vertical overlapping synchronization information are respectively the cumulative value of the deviation area between the surveyed area of ​​the overlapping fixed subject in the current surveying and mapping picture and the actual corresponding overlapping fixed subject, and the corresponding surveying and mapping clarity deviation value of the fixed subjects at different heights in the current surveying and mapping picture.

[0017] As a preferred embodiment of the present invention, if the horizontal overlapping synchronization information exceeds the cumulative threshold of the deviation area, or the vertical overlapping synchronization information exceeds the clarity deviation threshold, a synchronization deviation control signal is generated; if the horizontal overlapping synchronization information does not exceed the cumulative threshold of the deviation area, and the vertical overlapping synchronization information does not exceed the clarity deviation threshold, a normal synchronization surveying and mapping signal is generated.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, the impact of satellite surveying and mapping is analyzed to infer whether the current remote sensing surveying and mapping terminal is affected by the environment during satellite positioning or data collection, thereby causing deviations in surveying and mapping accuracy, thereby reducing surveying and mapping accuracy and making it impossible to adjust surveying and mapping accuracy in real time. Satellite test impact control can ensure the stability of remote sensing surveying and mapping, so as to facilitate timely adjustment when the environment affects it;

[0022] Adjust the distribution of monitoring stations in the real-time mapping area, reasonably distribute the monitoring stations based on the terrain analysis in the real-time mapping area, control the actual investment cost of the mapping stations while meeting the monitoring needs of the current mapping area to ensure real-time monitoring efficiency, and carry out targeted distribution based on the mapping conditions of the real-time mapping area, so as to conduct regional mapping more effectively and accurately.

[0023] 2. In the present invention, the synchronous ring surveying and mapping is detected to infer whether the actual needs are met in the current synchronous ring surveying and mapping process, so that the surveying and mapping accuracy of the current area is abnormal and cannot be visually controlled, which reduces the regional surveying and mapping efficiency. The synchronous ring detection can ensure that the large-area regional surveying and mapping can fit the actual area, thereby improving the surveying and mapping efficiency;

[0024] The asynchronous ring surveying is detected to infer whether the surveying efficiency of the mobile subject can be guaranteed when asynchronous ring surveying is carried out in the current surveying area, so as to monitor the terrain and other information of the current area more specifically according to the moving trajectory of the mobile subject, thereby improving the surveying efficiency and accuracy and facilitating visual control. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0026] Figure 1 It is a principle block diagram of the present invention. DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] See also Figure 1 As shown, a visual control system for surveying and mapping accuracy based on remote sensing surveying and mapping terminals includes a control platform, which is connected to a satellite surveying and mapping impact analysis unit, a surveying and mapping scheme adaptive adjustment unit, a synchronous ring detection unit, and an asynchronous ring detection unit; the remote sensing surveying and mapping of this system adopts a fixed installation monitoring station, and collects data from the fixed installation monitoring station through satellites;

[0030] The control platform generates a satellite surveying and mapping impact analysis signal and sends the satellite surveying and mapping impact analysis signal to the satellite surveying and mapping impact analysis unit. After receiving the satellite surveying and mapping impact analysis signal, the satellite surveying and mapping impact analysis unit analyzes the satellite surveying and mapping impact and infers whether the current remote sensing surveying and mapping terminal is affected by the environment during satellite positioning or data collection, thereby causing deviations in surveying and mapping accuracy, thereby reducing surveying and mapping accuracy and being unable to perform real-time surveying and mapping accuracy control. Satellite test impact control can ensure the stability of remote sensing surveying and mapping, so that timely adjustments can be made when there are environmental impacts.

[0031] The satellite cooperation terminal in the remote sensing mapping terminal is marked as a mapping satellite terminal, and the satellite clock difference between the atomic clock time installed on the mapping satellite terminal and the standard time is obtained. At the same time, the deviation span value of the amount of data transmitted under the current mapping satellite terminal signal fluctuation within the satellite clock difference is obtained, where the amount of data transmitted is pictures, images and other data;

[0032] The satellite clock difference between the atomic clock time installed on the mapping satellite and the standard time, and the deviation span value of the amount of data transmitted under the current mapping satellite signal fluctuation within the satellite clock difference are marked as clock difference data and data deviation data, respectively, and compared with the satellite clock difference threshold and deviation span threshold, respectively:

[0033] If the satellite clock difference between the atomic clock time installed on the surveying and mapping satellite and the standard time exceeds the satellite clock difference threshold, or the deviation span value of the amount of data transmitted under the current surveying and mapping satellite signal fluctuation within the satellite clock difference exceeds the deviation span threshold, it is inferred that the surveying and mapping impact analysis of the surveying and mapping satellite is abnormal, and a surveying and mapping impact signal is generated and sent to the control platform. After receiving the surveying and mapping impact signal, the control platform stores the real-time data of the fixed monitoring station at the current moment and transmits data when there is no environmental impact on the surveying and mapping satellite, and reduces the transmission frequency of the surveying and mapping satellite at the current moment, and needs to perform transmission data backup from the real-time data transmission terminal during transmission;

[0034] If the satellite clock difference between the atomic clock time installed on the surveying and mapping satellite and the standard time does not exceed the satellite clock difference threshold, and the deviation span value of the amount of data transmitted under the current surveying and mapping satellite signal fluctuation within the satellite clock difference does not exceed the deviation span threshold, it is inferred that the surveying and mapping impact analysis of the surveying and mapping satellite is normal, and a normal surveying and mapping signal is generated and sent to the control platform;

[0035] At the same time, an adaptive adjustment signal is generated and sent to the adaptive adjustment unit of the surveying and mapping scheme. After receiving the adaptive adjustment signal, the adaptive adjustment unit of the surveying and mapping scheme adjusts the distribution of monitoring stations in the real-time surveying and mapping area, and reasonably distributes the monitoring stations according to the terrain analysis in the real-time surveying and mapping area, controls the actual surveying and mapping station investment cost while meeting the monitoring needs of the current surveying and mapping area, so as to ensure the real-time monitoring efficiency, and at the same time, performs targeted distribution according to the surveying and mapping conditions of the real-time surveying and mapping area, so as to conduct regional surveying and mapping more effectively and accurately;

[0036] The real-time surveying and mapping area is divided into a number of equal-area sub-areas, and the real-time surveying and mapping area is pre-distributed with monitoring station locations according to the maximum surveying and mapping range of the surveying and mapping equipment in the monitoring station, and the current distribution points are set as the pre-distributed point planning;

[0037] The maximum coverage area of ​​the surveying and mapping range corresponding to a single monitoring station in the same type of sub-region in the preset point planning is obtained, and the maximum deviation value of the coverage area corresponding to different monitoring stations when there are multiple monitoring stations covering the same type of sub-region is obtained, and the maximum coverage area of ​​the surveying and mapping range corresponding to a single monitoring station in the same type of sub-region in the preset point planning and the maximum deviation value of the coverage area corresponding to different monitoring stations when there are multiple monitoring stations covering the same type of sub-region are marked as FGM and MJP respectively;

[0038] The deviation values ​​of the mean values ​​of the clarity of the corresponding surveying and mapping images in the coverage range of the same monitoring station in the different types of sub-areas in the preset point planning are collected, and the deviation values ​​of the mean values ​​of the clarity of the corresponding surveying and mapping images in the coverage range of the same monitoring station in the different types of sub-areas in the preset point planning are marked as QJP; the same type of sub-areas in this system are represented as the current area terrain slope and horizontality deviations do not exceed the set threshold, or the main body in the regional terrain is consistent, that is, they are all plant surfaces or rock surfaces;

[0039] The above collected data are uniformly marked as surveying and mapping scheme adjustment information, and substituted into the formula to obtain the adjustment coefficient of the preset point in the preset point planning, where the formula is: Wherein, TZ is the adjustment coefficient of the preset point, hj1, hj2 and hj3 are the preset proportional coefficients, e is a natural constant, and α is an error correction factor with a value of 0.98;

[0040] Compare the adjustment coefficient of the preset point in the preset point planning with the adjustment coefficient threshold:

[0041] If the adjustment coefficient of the preset point in the preset point planning exceeds the adjustment coefficient threshold, it is inferred that the preset point currently collected needs to be adjusted, and an adaptive adjustment signal is generated and sent to the control platform. After receiving the adaptive adjustment signal, the control platform adjusts the position of the current preset point. The specific adjustment direction is: when multiple monitoring stations are involved in the same area, if the maximum difference in the coverage area of ​​the monitoring station is too large, the monitoring station with a low coverage area is adjusted to move the position to reduce the number of monitoring stations in the area, avoid high data collection and processing intensity, and easily cause errors; when there is a deviation in clarity, the monitoring station is moved to ensure that the coverage range can better map the current coverage area;

[0042] If the adjustment coefficient of the preset point in the preset point planning does not exceed the adjustment coefficient threshold, it is inferred that the preset point currently collected does not need to be adjusted, and an adaptive qualified signal is generated and sent to the control platform;

[0043] After receiving the adaptive qualified signal, the control platform adjusts the current preset point planning and obtains the confirmed point planning; the surveying and mapping links are divided according to the fixed subjects and mobile subjects in the coverage area of ​​the confirmed point planning, that is, when surveying the fixed subject, the corresponding multiple area surveying marks are marked as synchronous rings, such as a piece of trees, a piece of rock surface, etc.; when surveying the mobile subject, the corresponding mobile area surveying marks are marked as asynchronous rings, such as animals and other moving objects;

[0044] At the same time, a synchronous ring detection signal is generated and sent to the synchronous ring detection unit. After receiving the synchronous ring detection signal, the synchronous ring detection unit detects the synchronous ring mapping and infers whether the current synchronous ring mapping process meets the actual needs, so that the mapping accuracy of the current area is abnormal and cannot be visually controlled, which reduces the regional mapping efficiency. Through synchronous ring detection, it can ensure that the mapping of a large area can fit the actual area, thereby improving the mapping efficiency;

[0045] When fixed subjects overlap during the synchronization ring detection process, the cumulative value of the deviation area between the surveyed area of ​​the overlapping fixed subjects in the current surveying and mapping picture and the actual corresponding overlapping fixed subjects is obtained, wherein the surveyed area of ​​the fixed subjects is more than the actual area or less than the actual area, which is the deviation area; if the pine tree group and the cypress tree group overlap, the area surveyed for the pine tree group is too large, and the area surveyed for the cypress tree group is too small, then the area deviation value is accumulated and calculated; and the cumulative value of the deviation area between the surveyed area of ​​the overlapping fixed subjects in the current surveying and mapping picture and the actual corresponding overlapping fixed subjects is marked as the horizontal overlap synchronization information;

[0046] At the same time, the corresponding surveying and mapping clarity deviation values ​​of the fixed subjects at different heights in the current surveying and mapping picture are obtained, and the corresponding surveying and mapping clarity deviation values ​​of the fixed subjects at different heights in the current surveying and mapping picture are marked as vertical overlapping synchronization information;

[0047] And compare with the deviation area accumulation threshold and clarity deviation threshold respectively:

[0048] If the cumulative deviation value between the surveyed area of ​​the overlapping fixed subject in the current surveying and mapping picture and the actual corresponding overlapping fixed subject exceeds the cumulative deviation area threshold, or the corresponding surveying and mapping clarity deviation values ​​of the fixed subjects at different heights in the current surveying and mapping picture exceed the clarity deviation threshold, it is inferred that the surveying and mapping data of the fixed subject in the corresponding area of ​​the synchronous ring surveying and mapping in the current surveying and mapping picture is biased, and a synchronous deviation control signal is generated and sent to the control platform. After receiving the synchronous deviation control signal, the control platform re-surveys the current synchronous ring surveying and mapping area, changes the surveying and mapping angle, and offsets the focus position;

[0049] If the cumulative deviation value of the surveyed area of ​​the overlapping fixed subject in the current surveying and mapping picture and the actual corresponding overlapping fixed subject does not exceed the cumulative deviation area threshold, and the corresponding surveying and mapping clarity deviation values ​​of the fixed subjects at different heights in the current surveying and mapping picture do not exceed the clarity deviation threshold, it is inferred that the fixed subject surveying and mapping data of the corresponding area of ​​the synchronous ring surveying and mapping in the current surveying and mapping picture has no deviation, and a normal synchronous surveying and mapping signal is generated and sent to the control platform; in this system, when there are only fixed subjects in the surveying and mapping area, synchronous ring surveying and mapping is performed, otherwise asynchronous ring surveying and mapping is additionally performed when there are fixed subjects and mobile subjects. Synchronous ring surveying and mapping refers to the single surveying and mapping of the corresponding monitoring station in the current area, and asynchronous ring surveying and mapping refers to the synchronous surveying and mapping of multiple monitoring points in the current area or multiple areas; more comprehensive surveying and mapping through the trajectory of the mobile subject;

[0050] At the same time, an asynchronous ring detection signal is generated and sent to the asynchronous ring detection unit. After receiving the asynchronous ring detection signal, the asynchronous ring detection unit detects the asynchronous ring surveying and infers whether the surveying efficiency of the mobile subject can be guaranteed when the asynchronous ring surveying and mapping is performed in the current surveying and mapping area, so as to monitor the terrain and other information of the current area more specifically according to the moving trajectory of the mobile subject, thereby improving the surveying and mapping efficiency and accuracy and facilitating visual control;

[0051] When a single mobile subject moves across regions during the asynchronous ring mapping process, the frame loss rate of the real-time mapping pictures of the corresponding monitoring stations participating in the mapping is obtained, where the frame loss rate indicates that there are mapping omissions or pictures with unusable clarity in the moving trajectory of the mobile subject; at the same time, when the corresponding moving trajectories of multiple mobile subjects overlap during the asynchronous ring mapping process, the deviation value of the mapping distance of the monitoring station mapping picture trajectory and the actual distance is obtained, and the frame loss rate of the real-time mapping pictures of the corresponding monitoring stations participating in the mapping when a single mobile subject moves across regions during the asynchronous ring mapping process and the deviation value of the mapping distance of the monitoring station mapping picture trajectory and the actual distance when the corresponding moving trajectories of multiple mobile subjects overlap during the asynchronous ring mapping process are marked as asynchronous single frame loss data and asynchronous multiple deviation data, and are compared with the frame loss rate threshold and distance deviation threshold respectively:

[0052] If during the asynchronous ring surveying and mapping process, when a single mobile subject moves across regions, the frame loss rate of the real-time surveying and mapping picture of the corresponding monitoring station participating in the surveying and mapping exceeds the frame loss rate threshold, or when the corresponding moving trajectories of multiple mobile subjects overlap during the asynchronous ring surveying and mapping process, the deviation value between the surveying and mapping distance of the monitoring station surveying and mapping picture trajectory and the actual distance exceeds the distance deviation threshold, it is inferred that there is a deviation in the surveying and mapping of the mobile subject of the asynchronous ring surveying, and a mobile surveying and mapping deviation signal is generated and sent to the control platform. After receiving the mobile surveying and mapping deviation signal, the control platform adjusts the accuracy of the surveying and mapping equipment of the monitoring stations within the surveying and mapping area;

[0053] If a single mobile subject moves across regions during the asynchronous ring surveying process, the frame loss rate of the real-time surveying image of the corresponding monitoring station participating in the surveying does not exceed the frame loss rate threshold, and when the corresponding moving trajectories of multiple mobile subjects overlap during the asynchronous ring surveying process, the deviation value between the surveying distance of the monitoring station's surveying image trajectory and the actual distance does not exceed the distance deviation threshold, then it is inferred that there is no deviation in the surveying of the mobile subject of the asynchronous ring surveying, and a mobile surveying qualified signal is generated and sent to the control platform.

[0054] The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The coefficients in the formula are set by technicians in this field according to actual conditions;

[0055] When the present invention is in use, the satellite surveying and mapping impact analysis unit collects clock error data and numerical deviation data, and infers whether the surveying and mapping impact analysis of the current surveying and mapping satellite end is abnormal based on data analysis, so as to facilitate regional surveying and mapping regulation; the surveying and mapping scheme adaptive adjustment unit sets the preset point planning according to the current distribution point; collects surveying and mapping scheme adjustment information, and obtains the adjustment coefficient of the preset point in the preset point planning, and infers whether the current preset point needs to be adjusted through adjustment coefficient comparison, and obtains the determined point planning through analysis and adjustment; the synchronous ring detection unit detects the synchronous ring surveying and mapping, collects horizontal overlapping synchronization information and vertical overlapping synchronization information, and infers whether there is a deviation in the synchronous ring surveying and mapping based on information analysis, and performs surveying and mapping regulation; the asynchronous ring detection unit detects the asynchronous ring surveying and mapping, collects asynchronous single frame loss data and asynchronous multiple deviation data, infers that there is a deviation in the mobile subject surveying and mapping of the asynchronous ring surveying and mapping, and performs surveying and mapping regulation.
