According to the scheme provided by the embodiment, when one visible image is operated, other visible images are correspondingly operated, and the synchronization of the loaded images can be realized. When the loaded images are a plurality of remote sensing images at different shooting moments in the same geographic space range, after synchronization, the geographic positions of pixels of the remote sensing images loaded at the same position of the display area are the same, so that when the dividing line is moved, the change of the same area can be conveniently compared, and the change trend of the corresponding area is obtained.
In an exemplary embodiment, the operation may include, but is not limited to, at least one of: zoom, move, hierarchy size change. The zooming refers to enlarging or reducing an image, when the image is a map or a remote sensing image, a display area only displays a partial area of the loaded image, and when moving operation is carried out, information of another area of the image is loaded to the display area. When the operation is a hierarchical size change operation, the operation comprises: and loading the image of the corresponding level to replace the current image. The system can store images of different levels at the same time in the same geographic position range, and the images of the corresponding levels are loaded when level size change operation is carried out.

If there may be multiple operations between the current synchronization operation and the previous synchronization operation, the multiple operations may be performed during synchronization, or corresponding changes may be performed on the visible images of other sub-display regions according to the state of the images of the sub-display regions after the multiple operations (for example, when the image of a certain sub-display region is scaled multiple times, and when the image of other sub-display regions is synchronized, only one scaling may be performed, and a final scaling state is reached). The operation can be recorded in a log mode to form log information, the log information comprises operation time when the operation is performed on the visible image in one sub-display area and the state of the visible image after the operation is performed, and then the synchronous operation can be performed on the visible images in the other sub-display areas according to the log information.
In an exemplary embodiment, when the operation on the image of one sub-display area is detected, the operation on the visible image of the sub-display area is performed, and corresponding operations are performed on the visible images of other sub-display areas according to the operation on the visible image of the sub-display area, including:
when detecting that the image of one sub-display area is operated, operating the visible image of the sub-display area, and executing the same operation on the visible images of other sub-display areas according to the operation on the visible image of the sub-display area when no new operation is performed within a preset time interval;
when detecting that the image of a sub-display area is operated, operating the visible image of the sub-display area, and if new operation exists in a preset time interval, continuing the detection until no new operation exists in the preset time interval after the current operation is detected, and determining the first operation before the current operation;
the state of the visible image of the sub-display area before the first operation is carried out is called as a first state, the state of the visible image of the sub-display area after the current operation is carried out is called as a last state, and corresponding operation is carried out on the visible images of other sub-display areas according to the first state and the last state;
and all the operations from the first operation to the current operation, wherein the time interval between adjacent operations is smaller than the preset time interval, and the time interval between the first operation and the previous operation of the first operation is larger than the preset time interval or no operation exists before the first operation.
In this embodiment, the initial state is a state before the initial operation is performed on the visible image in the sub display region. The preset time interval may be set as desired. The scheme provided by the embodiment can avoid the image synchronization which is too frequent, and reduce the system load, in addition, when a plurality of operations exist, the operation can be performed on the visible images of other sub-display areas once according to the state of the visible images in the corresponding sub-display areas before the first operation and the state of the visible images in the corresponding sub-display areas after the last operation in the plurality of operations, so that the states of the visible images in the other sub-display areas are the same as the states of the visible images in the corresponding sub-display areas, and the method not only can simplify the operation and improve the efficiency, but also can reduce the system load.

when detecting that the image of one sub-display area is operated, operating the visible image of the sub-display area, and executing the same operation on the visible images of other sub-display areas according to the operation on the visible image of the sub-display area when no new operation is performed within a preset time interval;
when detecting that the image of a sub-display area is operated, operating the visible image of the sub-display area, and if new operation exists in a preset time interval, continuing the detection until no new operation exists in the preset time interval after the current operation is detected, and determining the first operation before the current operation;
the state of the visible image of the sub-display area before the first operation is carried out is called as a first state, the state of the visible image of the sub-display area after the current operation is carried out is called as a last state, and corresponding operation is carried out on the visible images of other sub-display areas according to the first state and the last state;
and all the operations from the first operation to the current operation, wherein the time interval between adjacent operations is smaller than the preset time interval, and the time interval between the first operation and the previous operation of the first operation is larger than the preset time interval or no operation exists before the first operation.
7. The method for displaying images capable of realizing multi-dimensional contrast according to any one of claims 1 to 6, wherein the steps of acquiring a plurality of images, overlapping and loading the plurality of images to be displayed in a display area comprise:
acquiring a plurality of remote sensing images with the same number as the sub-display areas and different shooting moments in the same geographic space range, wherein the levels of the remote sensing images are the same;
and loading each remote sensing image in an overlapped mode and displaying the display area, wherein the geographic positions of the pixels of the remote sensing images loaded at the same position of the display area are the same.
