All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic flowchart of a method for determining an environmental level of a absorption field according to an embodiment of the present application. The main body of execution of the method may be, for example, a server that processes the remote sensing image. As shown in fig. 1, the method may include:
s101, acquiring at least one remote sensing image of the absorption field acquired by at least one acquisition device.
The acquisition equipment can be called as a remote sensing instrument, the remote sensing instrument acquires a remote sensing image of a target object (such as a consumption field) by being carried on a remote sensing platform, and the remote sensing platform can be a high balloon, an airplane, an artificial satellite, a manned spacecraft and the like. The remote sensing instrument can send the obtained remote sensing image to a server capable of processing the image through the information transmission equipment and the receiving device, and the server can process the remote sensing image to obtain target data.
Specifically, the remote sensing image of the absorption field can be obtained in two ways, one way is to determine the remote sensing image of the absorption field from the obtained remote sensing image by using the POI (Point of Information) of the absorption field in the internet interest Point data, wherein the POI of the absorption field at least comprises name Information and geographical position Information. For example, a satellite remote sensing platform acquires a remote sensing image of a city A, the city A comprises a consumption field B, and the server acquires the remote sensing image of the consumption field B from the remote sensing image of the city A according to geographical position information in POI of the consumption field B. The other mode is that the texture features of the absorption field on the remote sensing image can be used for identifying the absorption field from the remote sensing image, and the remote sensing image of the absorption field can be acquired under the condition that POI information of the absorption field is unknown.
Specifically, the remote sensing image of the absorption field may be acquired according to a preset period, for example, the remote sensing image of the absorption field every month may be acquired in a month period, and then information on the remote sensing image of the absorption field is analyzed to obtain a parameter for evaluating the environment level of the absorption field, where the parameter may include area information of the absorption field, area information of deposits included in the absorption field, and the like, and further, the environment level of the absorption field is determined according to the parameter, and determining the environment level of the absorption field is equivalent to evaluating the environment management level (level) of the absorption field. It should be noted that, the present application does not limit the number of remote sensing images of the absorption field acquired every month, nor the manner of acquiring the remote sensing images of the absorption field, and the absorption field may specifically be a building waste absorption field, which is a place specially used for processing building waste, wherein the building waste may include waste residue, waste soil, sludge, waste materials, and the like.
The remote sensing image of the absorption field is obtained through the remote sensing technology, the internal condition of the absorption field can be comprehensively, objectively and quickly obtained, and then the precision of evaluating the environmental level of the absorption field is improved, namely, the precision of evaluating the environmental management level of the absorption field can be improved.
S102, determining the number of scattering points, the covering rate of a green net and the greening area rate in the digestion field based on the remote sensing image.
The range of the absorption field can be determined according to the remote sensing image of the absorption field and the geographic information spatial analysis technology, the boundary of the absorption field can be drawn based on the range, and then a vector list of the absorption field is obtained, wherein the vector list comprises the area and the longitude and the latitude of the absorption field. The absorption field contains various target information, and according to the principle that any object has spectral characteristics and different objects have different absorption, reflection and radiation spectral properties, the scattering condition of garbage, the covering condition of garbage and the greening condition in the absorption field, namely the number of scattering points, the covering rate of green nets and the greening area rate, can be acquired based on the area of the absorption field.
S103, determining the environment level of the absorption field according to the number of the scattering points of the absorption field and the control rate.
The management and control rate of the absorption field is the sum of the green net covering rate and the greening area rate of the absorption field, that is, if only the index of the management and control rate is set on the server, the higher the management and control rate of the absorption field is, the higher the environmental level of the absorption field is, that is, the better the environment of the absorption field is, the higher the environmental management level is; if only the index of the number of scattering points is set on the server, the smaller the number of scattering points of the absorption field is, the higher the environmental level of the absorption field is proved to be, namely the more optimal the environment of the absorption field is, the higher the environmental management level is; when the two indexes of the number of the scattered points and the management and control rate are considered comprehensively, the server may determine the environmental level of the absorption farm based on a preset manner, for example, according to the weight of each index, which is not limited in the present application.
To sum up, in the method for determining an environmental level of an absorption field provided by the present application, at least one remote sensing image of the absorption field acquired by at least one acquisition device is acquired; determining the number of scattering points, the covering rate of a green net and the greening area rate in the digestion field based on the remote sensing image; and determining the environmental grade of the digestion site according to the number of scattering points of the digestion site and a control rate, wherein the control rate is the sum of the covering rate of the green net and the greening area rate. By adopting the method for determining the environment level of the absorption field provided by the embodiment of the application, the internal condition of the absorption field is obtained by analyzing the remote sensing image of the absorption field, wherein the condition can comprise the condition of muck scattering, the condition of covering and the condition of greening, namely the quantity of scattering points, the green net covering rate and the greening area rate in the absorption field, and the environment level of the absorption field can be evaluated according to the data to determine the environment level of the absorption field. By the method, the accuracy of evaluating the absorption field environment level can be improved.

The volume of the stack in the absorption field can be acquired at a preset frequency, which can be in months. The method comprises the steps of utilizing a stacking body three-dimensional modeling technology to model a stacking body in a remote sensing image of the absorption field to obtain a three-dimensional model corresponding to the stacking body, obtaining the height and the volume of the stacking body based on the three-dimensional model corresponding to the stacking body and a triangular grid method or a section method, and adopting other stacking body volume calculation methods without limitation. When the digestion site includes a plurality of deposits (such as muck), one of the target deposits may be selected to calculate the volume of the target deposit in the current month, i.e. the first deposit volume, or a plurality of the target deposits may be selected to calculate the volume of each target deposit in the current month, respectively, and the total volume is used as the first deposit volume.

S203, determining the consumption of the absorption field according to the volume change of the accumulation body.
Optionally, determining a difference between the first stack volume and the second stack volume; the ratio of the difference to the second stack volume is taken as the stack volume change rate.
Continuing with the above example, the second stack volume included in the absorption field in the previous month (period prior to the current period) also includes three cases, such as one target stack volume as the second stack volume and a total volume of a plurality of target stacks as the second stack volume. In general, the same rule is selected to calculate the accumulation volume change rate of the absorption field, and assuming that a target accumulation volume is used as the first accumulation volume and the second accumulation volume, the accumulation volume change rate of the absorption field can be calculated by the following formula:
the rate of change of volume of the stack of the absorption field (first stack volume-second stack volume)/second stack volume 100%
The consumption of the absorption field is evaluated through the volume change rate of the accumulation body of the absorption field, the larger the volume change rate of the accumulation body is, the larger the consumption of the absorption field is proved to be, and the consumption of the absorption field can be respectively evaluated by adopting the quantitative evaluation means, so that the accuracy of evaluation can be improved.

The management module stores attribute information of each absorption field in a preset absorption field set in advance, the attribute information can comprise name information, address information and the like of the absorption field, and the area, the longitude and the latitude of the absorption field and the attribute information of the absorption field can be stored in an associated mode.
S302, carrying out texture recognition on the remote sensing image, and determining the covering area, greening area and hardening area of the green net included in the absorption field.
The method comprises the steps of respectively identifying areas where different target objects are located through texture features of the different target objects (such as a green net, a greening plant and a hardened pavement) on a remote sensing image, segmenting the different target objects by using a multi-scale segmentation method to obtain the areas where the target objects are located, such as the area where the green net is located, the area where the greening plant is located, the area where the hardened pavement is located and the area where a house is located, and respectively calculating the areas of the areas by using an area calculation method to obtain the covering area of the green net, the greening area, the hardened area and the area of the house in the absorption field.
