An embodiment of the present application provides a video occlusion method, including the following steps:
s11: whether the current time is within a preset time period is detected.
Whether the current time is within a preset time period or not is detected, and the preset time period can be automatically formed or manually set according to specific conditions.
S12: and if the current time is within the preset time period, shielding the first area of the video.
If the current time is within the preset time period, the first area of the video is shielded, so that the privacy or the confidentiality of the first area is protected. The size of the first area may be automatically formed or manually set as the case may be. By providing the method for the preset time period, the device can automatically turn on and turn off the video shielding function according to the preset time period without frequently operating the device to turn on and turn off.
In other embodiments, if the current time is not within the preset time period, the first region of the video may be blocked, and only the preset time period needs to be adjusted.
Specifically, the method for modifying the preset time period comprises the following steps:
acquiring an instruction for modifying a preset time period;
and saving the modified preset time period. Thus the preset period modification is completed.
S13: whether a preset event occurs is detected.
And detecting whether a preset event occurs or not, wherein the preset event comprises the occurrence of a human face, object movement or environmental abnormality and the like. The preset event can be automatically set or manually set according to specific conditions.
S14: and if the preset event is detected to occur, the shielding of a second area of the video is cancelled, wherein the second area is the area where the preset event occurs.
The second area may be a face appearance area, an object area where movement occurs, an environmental area where abnormality occurs, or the like, and the size of the second area may be automatically formed or manually set according to specific situations. And if the preset event is detected to occur, the shielding of a second area of the video is cancelled, wherein the second area is the area where the preset event occurs, so that a user can observe the video data in time and take corresponding measures.
Note that, at this time, the priority of the preset event is higher than the preset time period. Specifically, canceling occlusion of the second region of the video comprises:
s141: and judging whether the second area comprises the first area.
The relationship between the second area A and the first area B comprises the following steps:
as shown in fig. 3, the parts of the first area a and the second area B intersect to form an intersection area;

as shown in fig. 5, the first area a is included by the second area B, and the first area a is an intersection area.
As shown in fig. 6, the first area a and the second area B do not have an intersection area.
It is determined whether the second area a contains the first area B, as is the case in fig. 5.
S142: and if so, canceling the shielding of the first area.
And if the second area comprises the first area, the shielding of the first area is canceled.
As shown in fig. 5, when the first area a is completely contained by the second area B, the first area a is an intersection area and is completely located within the range of the second area B, since the priority of the preset event is higher than the priority of the preset time period, the second area B is controlled to close the occlusion, that is, the occlusion of the first area a is cancelled.
S143: if not, the occlusion of the intersection area of the first area and the second area is cancelled, and the occlusion of the non-intersection area in the first area is maintained.
As shown in fig. 3, when there is intersection between the first area a and the second area B to form an intersection area, since the priority of the preset event is higher than the priority of the preset time period, the second area B is controlled to close the occlusion, that is, the intersection area of the first area a and the second area B is controlled to close the occlusion, and the non-intersection area of the first area a except the intersection area maintains the occlusion.
As shown in fig. 4, when the first area a completely includes the second area B, which is an intersection area, since the priority of the preset event is higher than the priority of the preset time period, the intersection area is controlled to close the occlusion, and the non-intersection area of the first area a without the intersection area maintains the occlusion.
As shown in fig. 6, there is no intersection region between the first region a and the second region B, i.e. the intersection region is zero, and the first region a maintains occlusion.
Thereby open when the first region A in the video of predetermineeing the period and shelter from, when taking place again in the video simultaneously and predetermineeing the event, predetermine the relevant second region B of event and close and shelter from, the user of being convenient for in time looks over video data, both furthest has satisfied privacy protection's original intention, also can satisfy the scene requirement that needs look over original video data under the shelter from the region for the video shelters from the function more intelligent, promotes user experience.
In other embodiments, prior to detecting whether the preset event occurs, the method further comprises:
and detecting whether the preset time period is associated with the preset event or not, and if so, continuously detecting whether the preset event occurs or not. Whether the preset time period is associated with the preset event or not is detected, and if yes, whether the preset event occurs or not is detected. Thereby use the mode of different preset condition linkages to video shelter from the region and adjust, through setting up the priority to different preset conditions to shelter from the region to different preset conditions and compare, dynamic adjustment video shelters from the region, both furthest has satisfied privacy protection's original intention, also can satisfy the scene requirement that needs look over original video data under the shelter from the region, makes the video shelter from the function more intelligent, promotes user experience.
It should be noted that in this embodiment, two preset conditions are provided, which are a preset time period and a preset event, respectively, in other embodiments, one, three or more preset conditions may be provided, different preset conditions have different priorities, and the video occlusion area is dynamically adjusted by comparing the occlusion areas of different preset conditions, so that the video occlusion method is more intelligent, and the control conditions are more diversified.
S15: if the preset event is not detected to occur, the shielding of the first area of the video is maintained.
If the preset event is not detected, the shielding of the first area of the video is maintained, and the privacy or confidentiality of the first area is ensured.
S16: and if the current time is not within the preset time period, the first area of the video is not shielded.
If the current time is not within the preset time period, it is indicated that the first area does not need to be protected at this time, so that the first area of the video is not shielded, and the staff can conveniently check the video content.
