Fig. 1B schematically illustrates a schematic view of a pane to which an embodiment of the present disclosure is applied.
According to an embodiment of the present disclosure, a display area of a terminal device may be divided into a plurality of panes. For example, as shown in FIG. 1B, a display area may be divided into four panes, A, B, C, and D. In other embodiments, the display area may also be divided into other numbers of panes, such as 2, 6, 8, 9, 12, 15, 16, etc., for example. Each pane may be used to display a path of surveillance video data.
Fig. 2 schematically illustrates a flowchart of a pane screen playing method according to an embodiment of the present disclosure.
As shown in fig. 2, the pane screen playing method includes operations S210-S240.
In operation S210, the received surveillance video data is presented in a pane.
In operation S220, in case that it is recognized that the surveillance video data includes the target object, a region to be enlarged is determined based on an enlargement rule.
In operation S230, in the case where the quasi-magnified region causes a collision, a modified region is determined based on a collision processing rule.
In operation S240, the target object is enlarged to the modified area for presentation.
According to the embodiment of the disclosure, each pane may be used to display one path of monitoring video data. And detecting the monitoring video data while displaying to identify whether the monitoring video data contains the target object. The algorithm for identification may be any of various known algorithms, for example, by using any suitable neural network model.
According to the embodiment of the disclosure, the target object may include a person, and the portrait is generally regarded as important picture information, and may be identified with respect to the portrait. The target object may also include an alarm device. The administrator can add the device pictures to be identified and train the identification model. Such as alarm devices with alarm lights, especially alarm devices that require a focused view. Thus, during the playing process, the system can identify the alarm device.
According to the embodiment of the present disclosure, after the target object is identified, the area where the target object is located, hereinafter simply referred to as the target area, may be determined. The target area may be, for example, a circumscribed rectangular area of the target object. The target area may then be enlarged in the hope of showing the details of the target object more clearly. For example, if a portrait is identified, the target area where the portrait is located can be amplified and played, so that in a multi-pane playing mode, not only can simultaneous playing of multiple camera pictures be satisfied, but also important information can be clearly seen.
According to embodiments of the present disclosure, the amplification rules may be configured proactively. For example, the administrator may configure the magnification to be 1.5 times, 2 times, 3 times, or the like. The position of the enlarged region may also be configured. In some embodiments of the present disclosure, the position of one vertex of the region in which the target object is located may be kept unchanged, and the region to be magnified is determined based on a preset magnification. In other embodiments of the present disclosure, the position of the central point of the region where the target object is located may be kept unchanged, and the region to be magnified is determined based on a preset magnification.
For example, in pane A, a target object is identified in an 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 is enabled to be 1 Magnification by two times will result in a quasi-magnified region A as shown in FIG. 3B 1 '. If the center position is kept unchanged, the target area is enlarged by two times, and a quasi-enlargement area A as shown in FIG. 3C is obtained 1 '. If the center position is kept unchanged, the target area is enlarged by three times, and a quasi-enlargement area A shown in FIG. 3D is obtained 1 ’。
According to the embodiment of the disclosure, if the area to be enlarged conflicts with other contents to be displayed in space, a correction area is determined according to a conflict processing rule, so that the target object is enlarged to the correction area for displaying. For example, in the case where two target regions exist in the same pane, if two regions to be enlarged overlap, the two regions to be enlarged may be reduced so as not to overlap, thereby determining the correction region. Further embodiments will be described in detail below.
According to the embodiment of the present disclosure, the above is described with the terminal device as the execution subject, and the method of the embodiment of the present disclosure may also be partially or completely executed by the server. For example, the server may type the received surveillance video data according to the pane, identify the surveillance video data, determine a final enlargement area according to the enlargement rule and the conflict processing rule, and then send a picture to be displayed finally to the terminal device for display.
According to the technical scheme of the embodiment of the disclosure, the monitoring video data is displayed and identified, when the target object is identified, the region where the target object is located is amplified and displayed through the amplification rule and the conflict resolution rule, so that the simultaneous observation of multiple paths of videos is ensured, the key information can be amplified and watched, details are not easy to omit, different requirements are considered, and the utilization rate of the screen is improved.
Fig. 4 schematically illustrates a flow chart for determining a correction region 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 a case where the quasi zoom-in region conflicts with an existing zoom-in region within a current pane, display parameters of the quasi zoom-in region and the existing zoom-in region are adjusted so that the quasi zoom-in region does not overlap with the existing zoom-in region.
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 monitoring video data, and after the target areas are respectively processed according to the amplification rule, a is obtained 1-1 And A 2-1 Two regions to be magnified. However, the two areas to be magnified partially overlap, resulting in a portion of the key content not being visible. At this time, the two quasi amplification areas 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 modified as shown in FIG. 5B as modified area A 1-2 And A 2-2 。
According to the embodiment of the disclosure, in the case that the area to be enlarged conflicts with the boundary of the current pane, if the preset parameter indicates that the display exceeding the pane is allowed, the area to be enlarged is determined as the correction area, such as the area a shown in fig. 7A 3-1 . If the preset parameters indicate that exceeding the window pane display is not allowed, the area to be magnified needs to be adjusted.
Fig. 6 schematically illustrates a flow chart for determining a correction region 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 display exceeding the pane is not allowed in the case that the area to be enlarged conflicts with the boundary of the current pane, the display parameter of the area to be enlarged is adjusted so that the area to be enlarged 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 can 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 modified as shown in FIG. 7B as modified area A 3-2 。
Fig. 8 schematically illustrates a flow chart for determining a correction region 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 a case where the quasi zoom-in region conflicts with an existing zoom-in region in another pane, display parameters of the quasi zoom-in region and the existing zoom-in region are adjusted so that the quasi zoom-in region and the existing zoom-in region are displayed in the 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 monitored video data, and after the target areas are respectively processed according to the amplification rule, a is obtained 4-1 And C 1 Two regions to be magnified. However, the two areas to be magnified partially overlap, resulting in a portion of the key content not being visible. At this time, the two quasi amplification areas 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 caused to be respectively displayed within the respective panes without crossing the panes. The adjusted area may be modified as shown by modified area A in FIG. 9B 4-2 And C 2 。
Fig. 10A and 10B schematically illustrate a flowchart of a pane screen playing method according to another embodiment of the present disclosure.
As shown in fig. 10A and 10B, the method includes operations S1001-S1011 and S1021-S1029.
As shown in fig. 10A, in operation S1001, setting parameters are read.
According to the embodiment of the disclosure, the administrator can set for multi-pane playing, including setting of the magnification rule and the conflict resolution rule. For example, after identifying the area needing to be enlarged, whether the area needs to be enlarged is automatically enlarged; the coordinates of the amplification source point can be set, and amplification is started from the initial point of the coordinates of the identification area, or amplification is started from the central area; the magnification factor of automatic amplification can be set; whether overlap is allowed or automatic adjustment to a non-overlapping size can be set in the case where multiple magnification areas are contained within the pane; whether the beyond pane display is allowed or not can be set; it may be set if the pane size is exceeded, if other panes also need to be enlarged, whether to automatically zoom into the pane, etc.
In operation S1002, the reading system identifies the generated identification result to the monitoring video data.
According to the embodiment of the disclosure, after receiving data of a camera, decoding is performed first to obtain YUV data (YUV is a color coding method expressed by lightness and chroma); analyzing the decoded YUV data (for example, using opencv or other tools); comparing the picture with a preset comparison picture, and identifying whether the picture contains a specified target object, such as a portrait or an alarm device; if the comparison is successful, recording the identified region coordinates (x, y), the image size (w, h) and pixel points of the image data of the region; a picture may contain a plurality of areas to be enlarged, all of which need to be recorded. For example: magnification area 1 is large (coordinate) { (x, y) }, w, h, data [ ] }, magnification area 2 is large (coordinate) { (x, y) }, w, h, data [ ] }.
In operation S1003, if the target object is recognized, 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, and if not, operation S1004 is performed, normal display is performed.
In operation S1006, the magnification factor and the coordinates of the magnification source point are read, and the size and position of the magnified image, i.e., the display position of the region to be magnified, are calculated.
In operation S1007, whether multiple target areas exist in the same path of monitored video data is determined, and if yes, operation S1008 is performed, otherwise, the process proceeds to the pane determination process shown in fig. 10B.
In operation S1008, it is determined whether the target areas overlap, if so, operation S1009 is performed, otherwise, the process proceeds to the pane determination flow illustrated in fig. 10B.
In operation S1009, it is determined whether the overlapping is allowed according to the setting parameters, and if so, operation S1011 is performed to retain the original calculated position, otherwise, operation S1010 is performed to recalculate the image size and position so that they are not overlapped. And then enters 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, and display is enlarged in the pane.
In operation S1023, it is determined whether the display of the over pane is allowed according to the setting parameters, and if so, operation S1025 is performed to display the over pane; otherwise, operation S1024 is performed, the size and position of the image are recalculated, and the image is adjusted to the maximum display in the pane.
In operation S1026, if the target object is also detected by the other pane and the enlarged display is required, operation S1027 is performed.
In operation S1027, it is determined whether overlay display is permitted according to the setting parameters, and if overlay display is set to be permitted, operation S1028 of overlay-displaying two target regions, for example, an enlarged image appearing later hides a preceding enlarged image, is performed. 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 in the two panes are recalculated, and the display is adjusted to the maximum display in the pane.
According to the technical scheme of the embodiment of the disclosure, the monitoring video data is displayed and identified, when the target object is identified, the region where the target object is located is amplified and displayed through the amplification rule and the conflict resolution rule, so that the multi-channel video can be observed at the same time, 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.
