Detailed Description
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
Fig. 1 is a flowchart of an environment monitoring method according to an exemplary embodiment, as shown in fig. 1, applied to a geographic information system (Geographic Information System, abbreviated as GIS) including a plurality of cameras disposed in a preset area, the method including:
in step 110, one or more target cameras are determined from a plurality of cameras.
The target camera is arranged in a first preset range around a target place in a preset area.
Illustratively, the positions of a plurality of cameras distributed in a preset area are recorded in advance in the geographic information system (or management unit thereof). Each camera can monitor a part of the area in the preset area. The position information of all cameras in the preset area and the position information of the target place (specified by a user or judged by a system) are represented by geographic coordinates (or universal longitude and latitude coordinates) in a GIS coordinate system provided by a GIS system. The first preset range may be a range with a center of the target location and a preset distance as a radius. The camera with the coordinates within the first preset range is the target camera. Thus, after determining the target location in the preset area, the target cameras distributed in the first preset range around the target location can be determined according to the position of each camera and the position of the target location.
In step 120, a target shooting angle of each target camera is determined according to an overlapping area of the shooting range of the one or more target cameras and a second preset range around the target location.
For example, the second preset range is a shooting range of the target location specified by the user, for example, for the specified location, the user needs to view an image within 10 meters of a square circle, which is the second preset range. The shooting range of the target camera needs to be completely overlapped with the second preset range as far as possible so as to achieve the optimal monitoring effect. In the embodiment of the disclosure, when the shooting area of the target camera and the second preset range do not completely overlap (or the overlapping area is too small), the shooting angle of the target camera may be adjusted according to the overlapping area (or the shooting range of the target camera is adjusted), so that the shooting range of the target camera reaches the expected value.
In step 130, an environment monitoring image of the target site is generated from the images captured by each of the target cameras at the target capturing angle.
For example, after each target camera is adjusted to the target shooting angle, since there may be an overlapping area in the images shot by the plurality of target cameras, the images shot by each target camera need to be processed and combined (including a non-overlapping area, a picture preprocessing, etc.), so as to generate an environment monitoring image of the target site. Therefore, after the target place appears in the geographic information system, the map information around the target place can be checked by utilizing the map display function of the geographic information system, and the video image around the target place shot by the target camera can be checked by the target camera.
In summary, according to the environmental monitoring method provided by the invention, one or more target cameras can be determined from a plurality of cameras, and the target cameras are arranged in a first preset range around a target place in the preset area; determining a target shooting angle of each target camera according to the overlapping area of the shooting range of the one or more target cameras and a second preset range around the target place; and generating an environment monitoring image of the target site through the image shot by each target camera at the target shooting angle. After the place needing to be monitored is determined, the place is subjected to image shooting through cameras around the place at a proper angle, so that a monitoring image of the place is obtained, and the comprehensiveness and instantaneity of environment monitoring are improved.
Fig. 2 is a flowchart of another environment monitoring method according to fig. 1, and as shown in fig. 2, before the step 110, the method further includes:
in step 140, a target location is determined.
The target location is an abnormal location detected by a preset environment detection unit, or a location designated by a map output by a user through the geographic information system.
The geographic information system further includes an environment detection unit (e.g., a monitoring satellite) for detecting environment information in an area covered by the geographic information system, and if it is determined whether an abnormal location occurs in the area, the abnormal location is used as a target location, so as to monitor the environment around the target location through steps 110 to 130, and an environment monitoring image is generated. Or when the display unit of the geographic information system presents the map of the preset area to the user, the user designates the place to be checked on the map through gesture operation, takes the place designated by the user as a target place, and further generates an environment monitoring image around the target place through steps 110 to 130.
Fig. 3 is a flowchart of an angle determining method according to the one shown in fig. 1, and as shown in fig. 3, the step 120 includes:
in step 121, an overlapping area is determined according to the shooting range of the one or more target cameras and the second preset range.
For example, an overlapping area of an overlapping region of a shooting range which can be shot by one or more target cameras and a second preset range is determined, and the larger the overlapping area is, the more comprehensive information of an environment monitoring image of the second preset range shot by the target cameras is represented. If the overlapping area is equal to the area of the second preset area, it is indicated that the shooting ranges of the one or more target cameras can completely cover the second preset range, and the user can view all the images in the second preset area through the images shot by the target cameras.
In step 122, if the overlapping area is determined to be smaller than the preset area, the shooting angle of each target camera is adjusted according to the shooting range and the second preset range so that the overlapping area is larger than the preset area.
Wherein, this shooting angle includes: the horizontal angle and the pitching angle of each target camera are positioned.
In step 123, the adjusted shooting angle is set as a target shooting angle.
For example, due to limitations of the position of the camera, the shooting angle, etc., it is difficult for the shooting range of the target camera to fully cover the second preset range in most cases, that is, the overlapping area is smaller than the area of the second preset area. Therefore, a preset area is set, if the overlapping area is larger than or equal to the preset area, the shooting range of the target camera can cover most areas in the second preset area, and a user can view a complete image around the target place through the image shot by the target camera. If the overlapping area is smaller than the preset area, the shooting range of the target camera can only cover a small part of the area in the second preset area, and the obtained monitoring image is not comprehensive enough. At this time, the shooting range of the target camera may be changed by adjusting the horizontal angle and the pitch angle of the target camera so that the overlapping area is increased until it is larger than the above-mentioned preset area (or the full overlapping is achieved). Or when the target camera is arranged on the unmanned aerial vehicle capable of freely moving, the position of the unmanned aerial vehicle and the shooting angle of the target camera arranged on the unmanned aerial vehicle can be adjusted simultaneously according to the overlapping area, so that the overlapping area is increased until the overlapping area is larger than the preset area (or the overlapping is completely achieved).
Fig. 4 is a flowchart of an area determining method according to fig. 3, and as shown in fig. 4, the step 121 includes:
in step 1211, the shooting range of each target camera is determined according to the initial shooting angle, the geographic coordinates, the azimuth angle, and the field angle of each target camera.
Wherein, this initial shooting angle includes: the horizontal angle and the pitching angle of each target camera are determined when the target site is determined.
In step 1212, the shooting ranges of the one or more target cameras are determined according to the shooting range of each target camera.
In step 1213, an overlapping area is determined according to the shooting range of the one or more target cameras and the second preset range.
For example, in the case where the photographing angle of each target camera is not adjusted (i.e., when determining the target location), the photographing angle of each target camera in the first preset area is an initial photographing angle including a horizontal angle and a pitch angle. According to the initial shooting angle, the geographic coordinates, the azimuth angle and the field angle of the target cameras, the shooting range of each target camera when the shooting angle is not adjusted can be determined. The number of the target cameras may be one or more, and when only one target camera is determined, the shooting range of the target camera is the shooting range of the target camera; when a plurality of target cameras are determined, fusing the shooting ranges of the plurality of target cameras according to a preset algorithm to determine the shooting ranges of all the target cameras in a first preset area.
Fig. 5 is a flowchart of an angle adjustment method according to the one shown in fig. 4, and as shown in fig. 5, the step 122 includes:
in step 1221, a degree of difference between the photographing range and the second preset range is obtained.
In step 1222, the amount of change in shooting angle required to adjust each target camera is determined based on the variance, initial shooting angle, geographic coordinates, azimuth, and field angle.
In step 1223, each of the target cameras is adjusted by the change amount of the shooting angle so that the overlapping area is larger than the preset area.
The difference degree includes, for example, a region area and a region position of a region that does not overlap between the second preset range and the photographing range. Because in the embodiment of the disclosure, the geographic coordinates, the azimuth angle and the view angle of each target camera are fixed, the shooting angle variation of each target camera is determined and adjusted by taking the geographic coordinates, the azimuth angle and the view angle as parameters through a preset angle algorithm and taking the difference and the shooting angle variation, and then each target camera is adjusted by the shooting angle variation so as to reduce the difference until the overlapping area is larger than the preset area.
Fig. 6 is a flowchart of an image generation method according to the one shown in fig. 5, and as shown in fig. 6, the step 130 includes:
in step 131, an image photographed by each target camera at a target photographing angle is acquired.
In step 132, the image captured by the one or more target cameras is converted into an environmental monitoring image according to the target capturing angle, the geographic coordinates, the azimuth angle, and the field angle of each target camera.
For example, after each target camera is adjusted to the target shooting angle, the image shot by each target camera may be synthesized into at least one complete environment monitoring image according to the target shooting angle, the geographic coordinates, the azimuth angle and the view angle of each target camera, and the environment monitoring image is displayed to the user through the display unit in the GIS, so that the user can view the environment information around the abnormal location.

After the place needing to be monitored is determined, the place is subjected to image shooting through cameras around the place at a proper angle, so that a monitoring image of the place is obtained, and the comprehensiveness and instantaneity of environment monitoring are improved.
