Fig. 1B schematically illustrates a schematic view of a pane to which embodiments of the present disclosure are applied.
According to the embodiment of the disclosure, the display area of the terminal device may be divided into a plurality of panes. For example, as shown in fig. 1B, a certain display area may be divided into A, B, C, D four panes. In other embodiments, the display area may be divided into other numbers of panes, such as 2, 6, 8, 9, 12, 15, 16, for example. Each pane may be used to present a path of surveillance video data.
Fig. 2 schematically illustrates a flowchart of a pane playing method of an embodiment of the present disclosure.
As shown in fig. 2, the pane playing method includes operations S210 to S240.
In operation S210, the received monitoring video data is displayed in a pane.
In operation S220, in case that the monitoring video data is recognized to include a target object, a region to be enlarged is determined based on an enlargement rule.
In operation S230, in case the quasi-enlarged region causes a conflict, a correction region is determined based on a conflict processing rule.
In operation S240, the target object is enlarged to the correction area for display.
According to embodiments of the present disclosure, each pane may be used to present a path of surveillance video data. And meanwhile, the monitoring video data can be detected to identify whether the monitoring video data contains a target object or not. The algorithm for identification can be various existing algorithms, for example, various suitable neural network models can be used.
According to the embodiment of the disclosure, the target object may include a person, and the person is considered to be important screen information, and may be identified for the person. The target object may also include an alarm device. The administrator can add the equipment pictures to be identified and train the identification model. Such as alarm devices with alarm indication lights, especially those which require a focused view. In this way, the system can identify the alarm device during the playing process.
According to the embodiment of the present disclosure, after the target object is identified, an area where the target object is located may be determined, hereinafter simply referred to as a target area. The target area may be, for example, a circumscribed rectangular area of the target object. The target area may be further enlarged to more clearly show the details of the target object. For example, if the portrait is identified, the target area where the portrait is located can be enlarged and played, so that in the multi-pane playing mode, the simultaneous playing of a plurality of camera pictures can be met, and important information can be clearly seen.
According to embodiments of the present disclosure, the magnification rules may be actively configured. For example, the administrator may configure the magnification to be 1.5 times, 2 times, 3 times, or the like. The location of the enlarged region may also be configured. In some embodiments of the present disclosure, the position of one vertex of the area where the target object is located may be kept unchanged, and the area to be amplified is determined based on a preset magnification. In other embodiments of the present disclosure, the location of the center point of the area where the target object is located may be kept unchanged, and the area to be amplified is determined based on a preset magnification.
For example, in pane A, a target object is identified in the area A 1 As shown in fig. 3A. If the fixed point position of the lower left corner is kept unchanged, the target area A 1 Twice the amplification will result in a quasi-amplified area A as shown in FIG. 3B 1 '. If the target area is doubled while keeping the center position unchanged, a quasi-amplified area A as shown in FIG. 3C is obtained 1 '. If the center position is kept unchanged, the target area is enlarged three times, and a quasi-enlarged area A as shown in FIG. 3D is obtained 1 ’。
According to the embodiment of the disclosure, if the to-be-enlarged area collides with other contents to be displayed in space, a correction area is determined according to a conflict processing rule so as to enlarge the target object to the correction area for displaying. For example, in the case where two target areas exist in the same pane, if two to-be-enlarged areas overlap, the two to-be-enlarged areas may be reduced so as not to overlap, thereby determining a correction area. Further embodiments will be described in detail below.
The method according to the embodiment of the present disclosure may be partially or completely executed by the server according to the embodiment of the present disclosure, which is described above with the terminal device as the execution body. For example, the server may typeset the received surveillance video data according to the pane, identify the surveillance video data at the same time, determine a final enlarged area according to the enlargement rule and the conflict processing rule, and then send the final picture to be displayed to the terminal device for display.
According to the technical scheme of the embodiment of the disclosure, the monitoring video data are displayed and identified, when the target object is identified, the area where the target object is located is amplified and displayed through the amplification rule and the conflict resolution rule, so that not only is the simultaneous observation of multiple paths of videos ensured, but also the key information can be amplified and watched, details are not easy to miss, different requirements are met, and the utilization rate of a screen is improved.
Fig. 4 schematically illustrates a flow chart of determining a correction area according to an embodiment of the present disclosure.
As shown in fig. 4, operation S230 may include operations S410 and S420.
In operation S410, in case that the quasi-enlarged region collides with an existing enlarged region within the current pane, display parameters of the quasi-enlarged region and the existing enlarged region are adjusted so that the quasi-enlarged region and the existing enlarged region do not overlap.
In operation S420, a correction area is determined based on the adjusted display parameter.
For example, as shown in fig. 5A, two target objects are identified in the same path of surveillance video data, the targets of whichThe regions are processed according to the amplification rule respectively to obtain A 1-1 And A 2-1 Two regions to be amplified. However, the two regions to be enlarged overlap partially, resulting in a portion of the key content not being visible. At this time, the two regions to be amplified may be adjusted so as not to overlap. For example, the magnification may be reduced, or the position of the region to be magnified may be moved while the magnification is reduced. The adjusted area may be the corrected area A as shown in FIG. 5B 1-2 And A 2-2 。
According to the embodiment of the disclosure, in the case that the to-be-enlarged area collides with the boundary of the current pane, if the preset parameter indicates that the pane display is allowed to be exceeded, the to-be-enlarged area is determined to be a correction area, such as an area A shown in fig. 7A 3-1 . If the preset parameters indicate that the pane display is not allowed to be exceeded, the quasi-zoom-in area needs to be adjusted.
Fig. 6 schematically illustrates a flow chart of determining a correction area according to another embodiment of the present disclosure.
As shown in fig. 6, operation S230 may include operations S610 and S620.
In operation S610, if the preset parameter indicates that the pane display is not allowed to be exceeded, the display parameter of the to-be-enlarged area is adjusted so that the to-be-enlarged area does not exceed the boundary of the current pane.
In operation S620, a correction region is determined based on the adjusted display parameter.
For example, as shown in FIG. 7B, the region to be magnified may be adjusted so that it does not exceed the pane. For example, the magnification may be reduced, or the position of the region to be magnified may be moved while the magnification is reduced. The adjusted area may be the corrected area A as shown in FIG. 7B 3-2 。
Fig. 8 schematically illustrates a flow chart of determining a correction area according to another embodiment of the present disclosure.
As shown in fig. 8, operation S230 may include operations S810 and S820.
In operation S810, in case that the quasi-zoom-in area collides with an existing zoom-in area in another pane, display parameters of the quasi-zoom-in area and the existing zoom-in area are adjusted so that the quasi-zoom-in area and the existing zoom-in area are displayed in respective panes.
In operation S820, a correction area is determined based on the adjusted display parameter.
For example, as shown in fig. 9A, two target objects are identified in two paths of monitoring video data, and target areas thereof are processed according to the magnification rule, respectively, to obtain a 4-1 And C 1 Two regions to be amplified. However, the two regions to be enlarged overlap partially, resulting in a portion of the key content not being visible. At this time, the two regions to be amplified may be adjusted so as not to overlap. For example, the magnification may be reduced, or the position of the region to be magnified may be moved while the magnification is reduced. For example, the adjusted regions may be individually displayed within respective panes without crossing the panes. The adjusted area may be the corrected area A as shown in FIG. 9B 4-2 And C 2 。
Fig. 10A and 10B schematically illustrate a flowchart of a pane playing method according to another embodiment of the present disclosure.
As shown in fig. 10A and 10B, the method includes operations S1001 to S1011 and S1021 to S1029.
As shown in fig. 10A, in operation S1001, a setting parameter is read.
According to embodiments of the present disclosure, an administrator may make settings for multi-pane playback, including settings for magnification rules and conflict resolution rules. For example, after the area to be enlarged is identified, whether to automatically enlarge or not; the magnification source point coordinates may be set, starting from the identification region coordinates starting point, or starting from the central region; the amplification factor of automatic amplification can be set; it may be provided that in the case of a pane containing a plurality of magnification areas, the overlap is allowed or automatically adjusted to a non-overlapping size; it may be set whether or not to allow for exceeding the pane display; it may be arranged if the pane size is exceeded, if other panes also need to be enlarged, if they are automatically reduced into the pane, etc.
In operation S1002, the reading system recognizes the recognition result generated for the monitoring video data.
According to the embodiment of the disclosure, after receiving the data of the camera, decoding is firstly performed to obtain YUV data (YUV is a color coding method represented by brightness and chromaticity); analyzing the decoded YUV data (for example, using an opencv tool); comparing the picture with a preset comparison picture, and identifying whether a specified target object such as a portrait or alarm equipment is contained; if the comparison is successful, recording the identified region coordinates (x, y) and image sizes (w, h), and the pixel points of the image data of the region; a picture may contain multiple regions that need to be enlarged and all need to be recorded. For example: the enlarged area 1{ coordinates { (x, y) }, w, h, data [ ] }, and the enlarged area 2{ coordinates { (x, y) }, w, h, data [ ] }.
In operation S1003, if a target object is identified, operation S1005 is performed, otherwise operation S1004 is performed, and normal display is performed.
In operation S1005, it is determined whether to automatically zoom in according to the setting parameters, if so, operation S1006 is performed, otherwise operation S1004 is performed, and normal display is performed.
In operation S1006, the magnification and the magnification source point coordinates are read, and the size and position of the magnified image, that is, the display position of the region to be magnified, are calculated.
In operation S1007, whether or not there are a plurality of target areas in the same path of the monitoring video data, if yes, operation S1008 is performed, otherwise, the pane judgment flow shown in fig. 10B is entered.
In operation S1008, it is determined whether or not a plurality of target areas overlap, and if so, operation S1009 is performed, otherwise, the flow of pane determination shown in fig. 10B is entered.
In operation S1009, it is determined whether overlap is allowed according to the setting parameters, if so, operation S1011 is performed, the original calculated position is reserved, otherwise, operation S1010 is performed, and the image size and position are recalculated so as not to overlap. And then proceeds to the pane judgment flow shown in fig. 10B.
As shown in fig. 10B, in operation S1021, it is determined whether the enlarged image exceeds the pane, and if so, operation S1023 is performed, otherwise, operation S1022 is performed to enlarge the display in the pane.
In operation S1023, determining whether to allow the exceeding of the pane display according to the setting parameters, and if so, executing operation S1025 to exceed the pane display; otherwise, operation S1024 is performed to recalculate the image size and position, and adjust to the maximum display in the pane.
In operation S1026, if the other pane also detects the target object, the enlarged display is required, operation S1027 is performed.
In operation S1027, it is determined whether or not the superimposition display is permitted based on the setting parameters, and if the superimposition display is permitted, operation S1028 is performed in which two target areas are superimposed and displayed, for example, a later-appearing magnified image covers a preceding magnified image. If the superimposed display is not allowed, the display is adjusted to the maximum display in the pane, for example, the size and the position of the correction area are recalculated in the two panes respectively, and the display is adjusted to the maximum display in the pane.
