All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic flow chart of an infrared lamp control method according to an embodiment of the present invention, where the method is applied to a multi-lens camera, and as for the structure of the multi-lens camera, reference may be made to fig. 3b and fig. 4 to 12 and corresponding descriptions, the following description of the method may include:

s101, displaying a configuration window, wherein the configuration window comprises a mapping table, and the mapping table is used for representing the mapping relation between a plurality of lenses and a plurality of infrared lamp groups.

In this embodiment, the configuration window may be further displayed after receiving a preset configuration instruction input by a user, and for example, the configuration window is displayed after the user clicks a configuration button in the control main interface. The application program may be a browser or a preset application program. The configuration window can be full screen or windowed, and can be switched between full screen and windowed according to the actual requirement of a user.

The mapping table is used for representing a mapping relationship between a plurality of infrared lamp groups and a plurality of lenses of the multi-lens camera, and further, each line in the mapping table is used for representing a mapping relationship between one infrared lamp group in the plurality of infrared lamp groups and a lens. Furthermore, each row may include two items, the first item is a serial number of the infrared lamp group, and the second item is a lens identifier of the lens. For example, row 1 in the mapping table may include "No. 1" and "Camera 2" to indicate that the infrared lamp group with the serial number "No. 1" and the lens with the lens identification "Camera 2" have a mapping relationship. It can be understood that, in this embodiment, for convenience of viewing by a user, rows in the mapping table may be sorted according to a descending order or a descending order of the serial numbers of the infrared lamp groups included in each column, and in other embodiments, the sorting of each column in the mapping table may also be determined according to actual needs of the user.

S102, receiving a first instruction input by a user, and starting one infrared lamp group in the plurality of infrared lamp groups according to the first instruction.

Further, the infrared lamp set may be turned on in response to a user clicking a preset region or a preset button corresponding to one infrared lamp set in the configuration window. Illustratively, a plurality of pull-down buttons are displayed in the configuration window, each pull-down button corresponds to one infrared lamp group, and when a user clicks the pull-down button corresponding to the infrared lamp group with the serial number "No. 1", the infrared lamp group with the serial number "No. 1" is turned on.

And S103, providing a video playing window, wherein the video playing window is used for displaying real-time monitoring images acquired by a plurality of lenses.

The video playing window may be a sub-window in the configuration window, or may be a window independent of the configuration window. It can be understood that the user can determine the light supplement effect of the opened infrared lamp bank to the plurality of lenses by comparing the monitoring images acquired by the plurality of lenses after the infrared lamp bank is opened, and then can select the lens suitable for being bound with the opened infrared lamp bank according to actual requirements. For example, assuming that there are four lenses, a first lens has a larger difference between the brightness of the monitoring image acquired before the infrared lamp set is turned on and the brightness of the real-time monitoring image acquired after the infrared lamp set is turned on, and the brightness of the real-time monitoring image acquired before the infrared lamp set is turned on and the brightness of the real-time video image acquired after the infrared lamp set is turned on are similar to each other, the user can clearly know that the light supplementing effect of the turned-on infrared lamp set on the first lens is the best.

Further, after the mapping relationship between the started infrared lamp set and the lens to be bound is determined, no mapping relationship exists between the started infrared lamp set and the lens corresponding to the started infrared lamp set. Illustratively, the lens to which the lens is to be bound is identified as "Camera 2", before S104 is executed, the turned-on infrared lamp set has a mapping relationship with the lens represented by "Camera 3", after S104 is completed, the turned-on infrared lamp set has a mapping relationship with only the lens represented by "Camera 2", and has no mapping relationship with the lens represented by "Camera 3", that is, each infrared lamp set has a mapping relationship with only one lens.

And S106, storing the mapping table until the mapping relation of any infrared lamp group in the plurality of infrared lamp groups is determined.

Further, in the present embodiment, different infrared lamp sets may have a mapping relationship with the same lens, for example, as shown in the following table:

No.1	Camera2
		No.2	Camera2
No.3	Camera3
		No.4	Camera4

the first column may indicate that a mapping relationship exists between the infrared lamp group with the serial number "No. 1" and the lens indicated by the lens identifier "Camera 2". It can be seen that, the infrared lamp group with serial number "No. 1" and serial number "No. 2" has a mapping relationship with the lens denoted by the lens identifier "Camera 2".

In another alternative embodiment, the mapping relationship between different infrared lamp sets and different lenses, and the one-to-one mapping relationship between a plurality of infrared lamp sets and a plurality of lenses may be as shown in the following table:

No.1	Camera2
		No.2	Camera1
No.3	Camera3
		No.4	Camera4

in this case, there is an infrared lamp group for infrared light supplement for each lens, and each infrared lamp group can exert the best light supplement effect.

And S107, controlling the plurality of infrared lamp groups to supplement light to the corresponding lenses based on the mapping table.

Further, when a lens in the multi-lens camera needs to be compensated, the infrared lamp group which has a mapping relation with the lens is turned on. Specifically, in an alternative embodiment, after determining that a lens in the night mode exists in the plurality of lenses, the infrared lamp group having a mapping relationship with the lens in the night mode is turned on according to the mapping table.

Further, it may be determined that there are a plurality of shots in the night mode in the following manner: firstly, checking an image brightness parameter corresponding to any one of a plurality of lenses, if the image brightness parameter corresponding to the lens is smaller than a preset brightness threshold value, determining that the lens is in a night mode, and folding an infrared filter corresponding to the lens. When the infrared filter of one lens is in a folding state, the infrared light incident to the lens cannot be cut off and can be normally sensed by the image sensor corresponding to the lens. It will be appreciated that if a lens

By adopting the embodiment, the mapping relation between the plurality of infrared lamp groups and the plurality of lenses of the multi-lens camera can be configured according to the actual requirements of the user through the preset configuration window, the infrared lamp light supplementing strategy can be more flexibly controlled, and then the infrared lamp light supplementing aiming at the multi-lens camera is realized, so that the monitoring effect of the multi-lens camera in the place with insufficient light is improved. .
