Description

Technical Field

[0001] The embodiments of the present application relate to the field of monitoring technology, and in particular to a method, device, medium, and electronic device for controlling a fill light of a dual-channel camera. Background Art

[0002] With technological advancements, dual-channel cameras are becoming increasingly common in surveillance systems. These cameras provide two separate monitoring screens. A common solution is: Channel 1, the panoramic camera channel, uses a wide-angle lens with a wide field of view, suitable for monitoring large scenes; Channel 2, the detail camera channel, features a pan / tilt system with a narrow field of view, suitable for monitoring smaller scenes.

[0003] Because the detail channel's pan / tilt can rotate, the two channels can monitor two completely different scenes. Alternatively, the panoramic channel can view the larger scene while the detail channel monitors a specific detail within the larger scene. Alternatively, the panoramic channel can perform intelligent operations while the detail channel can be linked to capture or track targets. Due to the differences in the lens' monitoring fields of view, the two channels use different fill lights. When the monitoring areas overlap, the fill lights of the two channels interfere with each other, especially the detail fill light's effect on the panoramic channel image. In the panoramic channel image, the area illuminated by the detail fill light is particularly bright. The panoramic channel, detecting the high brightness in this area, reduces its exposure parameters, resulting in even lower brightness in areas not illuminated by the detail fill light. This creates a significant contrast between light and dark in the image, and effectively loses monitoring information.

[0004] Currently, there is no technical solution to solve the problem of loss of panoramic channel image monitoring information when monitoring areas overlap. Summary of the Invention

[0005] The embodiments of the present application provide a method, device, medium and electronic device for controlling the fill light of a dual-channel camera, which can synchronously control the fill light of the panoramic channel according to the exposure parameters of the panoramic channel and the exposure parameters of the detail channel, prioritize the filling light of the panoramic channel to be turned on before the fill light of the detail channel, optimize the impact of the fill light of the detail channel on the panoramic channel when the monitoring areas overlap, and maximize the retention of effective information monitored by the two channels of the camera.

When the fill light intensity of the panoramic channel meets the preset intensity condition, the fill light of the detail channel is controlled to turn on based on the current exposure parameters of the detail channel.

[0023] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present application and are not intended to limit the present application. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions of the present application, not all of the structures.

[0024] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe the steps as sequential processes, many of the steps can be implemented in parallel, concurrently, or simultaneously. In addition, the order of the steps can be rearranged. The process can be terminated when its operation is completed, but can also have additional steps not included in the accompanying drawings. The process can correspond to a method, function, procedure, subroutine, subprogram, etc.

[0025] Example 1

[0026] Figure 1 This is a flowchart of the dual-channel camera fill light control method provided in Example 1 of the present application. This embodiment is applicable to the situation of controlling a dual-channel camera. The method can be executed by the dual-channel camera fill light control device provided in the embodiment of the present application. The device can be implemented by software and / or hardware and can be integrated into devices such as smart terminals for camera control.

[0027] like Figure 1 As shown, the dual-channel camera fill light control method includes:

[0028] S110, determining an overlapping area between the detail channel image and the panoramic channel image;

[0029] In this solution, the dual-channel camera is divided into two monitoring screens: a panoramic channel and a detail channel. The panoramic channel uses a wide-angle lens with a wide field of view, suitable for monitoring large scenes. The detail channel can be sleek with a pan / tilt system, but has a narrow field of view, suitable for monitoring smaller scenes.

[0030] The overlapping area may refer to the overlapping area of ​​the detail channel monitoring area and the panoramic channel monitoring area.

[0031] For example, Figure 2 This is a schematic diagram of the monitoring area provided in Example 1 of the present application. Figure 2 As shown in (a), when two channels monitor two completely different scenes respectively, the two channels have independent fill light modes; Figure 2 As shown in (b), when the monitoring areas overlap, the infrared fill lights of the two channels interfere with each other, especially the fill light of the detail channel has a more obvious impact on the panoramic channel image.

[0032] In this embodiment, when the fill-light area of ​​the detail channel is not within the panoramic image, the overlap area is zero and does not affect the panoramic image. However, when the fill-light area of ​​the detail channel is within the panoramic image, the overlap area will affect the panoramic image, resulting in loss of effective monitoring information. The overlap area of ​​the detail and panoramic channel images can be determined by capturing the relative position of the detail channel image within the panoramic channel image.

[0033] In this technical solution, optionally, determining the overlapping area between the detail channel image and the panoramic channel image includes:

[0034] Determine the relative position of the fill light area of ​​the detail channel in the panoramic channel image based on the gimbal coordinates of the detail channel and the fill light angle of the detail channel;

[0035] An overlapping area between the detail channel image and the panoramic channel image is determined according to the relative position.

[0036] In this solution, the processor obtains the fill light intensity and fill light angle of the panoramic channel and the fill light of the detail channel, and establishes a mapping relationship between the image coordinates and the gimbal coordinates between the two channels. After the calibration is completed, the relative positions of the monitoring screens of the two channels are obtained according to the current gimbal coordinates of the detail channel. Further, according to the data of the fill light area of ​​the detail channel, the relative position of the fill light area in the panoramic picture after the fill light of the detail channel is turned on is obtained, and then the overlapping area of ​​the detail channel image and the panoramic channel image is determined.

[0037] By determining the overlapping area of ​​the detail channel image and the panoramic channel image, the fill light of the dual-channel camera can be further controlled based on the size of the overlapping area.

[0038] S120: If the overlapping area does not meet the overlapping threshold condition, control the fill light of the panoramic channel to turn on according to the current exposure parameters of the panoramic channel and the current exposure parameters of the detail channel;

[0039] The overlap threshold condition can be used to characterize the comparison threshold for overlapping areas. It can be set based on the difference in fill light intensity between the detail channel and the panorama channel. For example, the overlap threshold condition can be set to M. If the overlapping area is less than or equal to M, the overlapping area meets the overlap threshold condition; if the overlapping area is greater than M, the overlapping area does not meet the overlap threshold condition.

[0040] In this embodiment, the exposure parameters include a shutter value, an aperture, and a gain value.

[0041] In this scheme, when the overlapping area does not meet the overlapping threshold condition, the fill light of the detail channel has a certain impact on the panoramic channel image. In this case, the fill light of the panoramic channel is jointly controlled according to the current exposure parameters of the panoramic channel and the current exposure parameters of the detail channel.

[0042] In this technical solution, optionally, controlling the fill light of the panoramic channel to turn on according to the current exposure parameters of the panoramic channel and the current exposure parameters of the detail channel includes:

[0043] Determining a current exposure parameter of the panoramic channel according to the brightness of the panoramic channel image; and determining a current exposure parameter of the detail channel according to the brightness of the detail channel image;

[0044] If the current exposure parameter of the panoramic channel meets the preset panoramic exposure threshold condition, then control the fill light of the panoramic channel to turn on; or,

[0045] If the current exposure parameter of the detail channel meets the preset first detail exposure threshold condition, the fill light of the panoramic channel is controlled to turn on.

[0046] The panoramic exposure threshold condition may refer to a comparison threshold of the exposure parameters of the panoramic channel. For example, the panoramic exposure condition may be set to X. When the current exposure parameter of the panoramic channel is greater than or equal to X, the current exposure parameter of the panoramic channel meets the preset panoramic exposure threshold condition; when the current exposure parameter of the panoramic channel is less than X, the current exposure parameter of the panoramic channel does not meet the preset panoramic exposure threshold condition.

[0047] In this embodiment, the first detail exposure threshold condition may refer to a comparison threshold of the exposure parameters of the detail channel. For example, the first detail exposure threshold condition may be set to Y'. When the current exposure parameter of the detail channel is greater than or equal to Y', the current exposure parameter of the detail channel satisfies the preset first detail exposure threshold condition. When the current exposure parameter of the detail channel is less than Y', the current exposure parameter of the detail channel does not satisfy the preset first detail exposure threshold condition.

[0048] In this solution, when the ambient illumination gradually decreases, the panoramic channel gradually increases the exposure parameters of the panoramic channel according to the brightness change of the panoramic channel image. The detail channel also gradually increases the exposure parameters of the detail channel according to the brightness change of the detail channel image. When the exposure parameters of the panoramic channel reach the panoramic exposure threshold condition, or when the exposure parameters of the detail channel reach the first detail exposure threshold condition, the fill light of the panoramic channel is controlled to turn on.

[0049] By synchronously controlling the panoramic channel's fill light according to the panoramic channel exposure parameters and the detail channel exposure parameters, the panoramic channel's fill light is prioritized to be turned on before the detail channel's fill light, optimizing the impact of the detail channel's fill light on the panoramic channel when the monitoring areas overlap.

[0050] S130: If the fill light intensity of the panoramic channel meets the preset intensity condition, the fill light of the detail channel is controlled to turn on according to the current exposure parameter of the detail channel.

[0051] The intensity condition is used to characterize the comparison threshold of the fill light intensity of the panoramic channel. Preferably, the intensity condition can be set to the maximum value of the fill light intensity of the panoramic channel.

[0052] In this embodiment, after the fill light of the panoramic channel is turned on, the fill light intensity is controlled to reach a maximum value according to the ambient brightness. At this time, the fill light of the detail channel is controlled to be turned on according to the current exposure parameter of the detail channel.

[0053] In this technical solution, optionally, if the fill light intensity of the panoramic channel meets the preset intensity condition, the fill light of the detail channel is controlled to turn on according to the current exposure parameter of the detail channel, including:

[0054] When the fill light intensity of the panoramic channel meets the preset intensity condition, the target exposure parameter of the detail channel is determined according to the brightness of the detail channel image;

[0055] If the target exposure parameter of the detail channel meets a preset second detail exposure threshold condition, the fill light of the detail channel is controlled to turn on; wherein the second detail exposure threshold condition is greater than the first detail exposure threshold condition.

[0056] The second detail exposure threshold condition may refer to a comparison threshold of the exposure parameter of the detail channel. For example, the second detail exposure threshold condition may be set to Y. When the target exposure parameter of the detail channel is greater than or equal to Y, the target exposure parameter of the detail channel satisfies the preset second detail exposure threshold condition; when the target exposure parameter of the detail channel is less than Y, the target exposure parameter of the detail channel does not satisfy the preset second detail exposure threshold condition.

[0057] In this embodiment, the second detail exposure threshold condition is greater than the first detail exposure condition, that is, the fill light of the detail channel can only be turned on after the fill light of the panoramic channel is turned on and reaches the maximum intensity.

[0058] In this solution, when it is detected that the fill light intensity of the panoramic channel reaches the maximum value, the detail channel increases the exposure parameter according to the brightness change of the detail channel image to reach the second detail exposure threshold condition, and controls the fill light of the detail channel to turn on.

[0059] By controlling the fill light of the detail channel to turn on, it can be ensured that the effective information monitored by the detail channel can be retained to the maximum extent.

[0060] For example, as shown in Table 1, when the ambient illumination gradually decreases, the panoramic channel gradually increases its exposure parameters based on changes in the brightness of the panoramic channel image. The detail channel also gradually increases its exposure parameters based on changes in the brightness of the detail channel image. When the panoramic channel exposure parameters reach the panoramic exposure threshold condition X, or when the detail channel exposure parameters reach the first detail exposure threshold condition Y', the panoramic channel's fill light is controlled to turn on, and the intensity of the panoramic channel's fill light is controlled from low to high. When it is detected that the panoramic channel's fill light intensity has reached its maximum value, the detail channel increases its exposure parameters based on changes in the detail channel's image brightness, and when the second detail exposure threshold condition Y is reached, the detail channel's fill light is controlled to turn on, and the intensity of the detail channel's fill light is controlled from low to high.

[0061] Table 1

[0062]

[0063] In this technical solution, optionally, after determining the overlapping area between the detail channel image and the panoramic channel image, the method further includes:

[0064] When the overlapping area meets the overlapping threshold condition, the fill light of the panoramic channel is controlled to be turned on or off according to the preset panoramic channel fill light condition; and the fill light of the detail channel is controlled to be turned on or off according to the preset detail channel fill light condition.

[0065] In this scheme, if the overlapping area is less than or equal to the overlapping threshold condition, each channel adopts the default exposure and fill light strategy independently of each other.

[0066] Specifically, the panoramic channel's fill light is controlled by the panoramic channel, and the condition for turning on the panoramic channel's fill light is set to be when the panoramic channel's exposure parameter reaches X. The detail channel's fill light is controlled by the detail channel, and the condition for turning on the detail channel's fill light is set to be when the detail channel's exposure parameter reaches Y. As the ambient illumination gradually decreases, the panoramic channel gradually increases its exposure parameter based on the brightness of the panoramic channel image. After the exposure parameter reaches the turn-on threshold condition X, the panoramic channel's fill light is turned on, and the fill light intensity is slowly adjusted from low to high. The detail channel gradually increases its exposure parameter based on the brightness of the detail channel image. After the exposure parameter reaches the turn-on threshold condition Y, the detail channel's fill light is turned on, and the fill light intensity is slowly adjusted from low to high. As the ambient illumination gradually increases, each channel adjusts in the opposite direction according to its own exposure line.

[0067] For example, as shown in Table 2, when the ambient illumination gradually decreases, the panoramic channel gradually increases the exposure parameter according to the brightness of the panoramic channel image, and after the exposure parameter reaches the light-on threshold condition X, the fill light of the panoramic channel is turned on, and the fill light intensity is slowly adjusted from small to large.

[0068] Table 2

[0069]

[0070] For example, as shown in Table 3, when the ambient illumination gradually decreases, the detail channel gradually increases the exposure parameter according to the brightness change of the detail channel image, and after the exposure parameter reaches the light-on threshold condition Y, the fill light of the detail channel is turned on, and the fill light intensity is slowly adjusted from small to large.

[0071] Table 3

[0072]

[0073] When the overlapping area meets the overlapping threshold condition, the fill light of the panoramic channel and the fill light of the detail channel are controlled separately, which can ensure the image effect when the two channels independently monitor different scenes.

[0074] The technical solution provided in the embodiments of the present application determines the overlapping area between the detail channel image and the panoramic channel image; if the overlapping area does not meet the overlap threshold condition, the panoramic channel's fill light is controlled to turn on based on the current exposure parameters of the panoramic channel and the current exposure parameters of the detail channel; if the intensity of the panoramic channel's fill light meets the preset intensity condition, the detail channel's fill light is controlled to turn on based on the current exposure parameters of the detail channel. By implementing this technical solution, the panoramic channel's fill light can be prioritized to turn on before the detail channel's fill light, optimizing the impact of the detail channel's fill light on the panoramic channel when the monitored areas overlap, and maximizing the retention of effective information monitored by both channels of the camera.

[0075] Example 2

[0076] Figure 3 This is a schematic diagram of the dual-channel camera fill light control process provided by the second embodiment of the present application. This second embodiment is further optimized based on the first embodiment. The specific optimization is: after controlling the fill light of the detail channel to turn on, the method further includes: when the environmental parameters meet the preset change conditions, adjusting the intensity of the fill light of the detail channel according to the brightness of the detail channel image until the fill light of the detail channel is turned off. Among them, the content not fully described in this embodiment is detailed in the first embodiment. Figure 3 As shown, the method includes the following steps:

[0077] S310, determining an overlapping area between the detail channel image and the panoramic channel image;

[0078] S320: If the overlapping area does not meet the overlapping threshold condition, control the fill light of the panoramic channel to turn on according to the current exposure parameters of the panoramic channel and the current exposure parameters of the detail channel;

[0079] S330: If the fill light intensity of the panoramic channel meets the preset intensity condition, control the fill light of the detail channel to turn on according to the current exposure parameter of the detail channel;

[0080] S340: When the environmental parameters meet the preset change condition, adjust the intensity of the fill light of the detail channel according to the brightness of the detail channel image until the fill light of the detail channel is turned off;

[0081] The environmental parameter may refer to the ambient illumination. The preset change condition may refer to the change condition of the ambient illumination, that is, the change process of the ambient illumination from dark to bright.

[0082] In this embodiment, when environmental parameters meet preset variations, the detail channel's fill light intensity is controlled, decreasing from high to low until it is turned off, based on changes in the detail channel's image brightness. The panorama channel's fill light remains active until the detail channel's fill light is turned off. If the panorama channel's image brightness is too bright at this point, the exposure parameters can be adjusted to bring the panorama channel's image brightness up to the target.

[0083] In this technical solution, optionally, after adjusting the intensity of the fill light of the detail channel according to the brightness of the detail channel image until the fill light of the detail channel is turned off, the method further includes:

[0084] If the current exposure parameter of the panoramic channel does not meet the preset panoramic exposure threshold condition, and if the current exposure parameter of the detail channel does not meet the preset first detail exposure threshold condition, the intensity of the fill light of the panoramic channel is adjusted until the fill light of the panoramic channel is turned off.

[0085] In this embodiment, after the fill light of the detail channel is turned off, the processor synchronously determines whether the exposure parameters of the panoramic channel and the detail channel need to be lowered, and whether the exposure parameters X and Y' for reducing the fill light intensity are reached. When both channels need to reduce the fill light intensity, the fill light intensity of the panoramic channel is gradually reduced until it is turned off. During this process of reducing the fill light intensity, if only one channel needs to reduce the exposure parameters, the channel can only adjust other exposure parameters first, such as reducing the gain, to make the image brightness reach the preset target brightness.

[0086] This solution not only ensures the image quality when the two channels independently monitor different scenes, but also optimizes the impact of detail fill light on the panoramic channel when the monitoring areas overlap, so that the effective information monitored by the two channels of the camera can be retained to the maximum extent.

[0087] The technical solution provided in the embodiment of the present application determines the overlapping area of ​​the detail channel image and the panoramic channel image; when the overlapping area does not meet the overlapping threshold condition, the fill light of the panoramic channel is controlled to turn on according to the current exposure parameters of the panoramic channel and the current exposure parameters of the detail channel; if the fill light intensity of the panoramic channel meets the preset intensity condition, the fill light of the detail channel is controlled to turn on according to the current exposure parameters of the detail channel. When the environmental parameters meet the preset changes, the intensity of the fill light of the detail channel is adjusted according to the brightness of the detail channel image until the fill light of the detail channel is turned off. By implementing this technical solution, it is possible to prioritize the fill light of the panoramic channel to turn on before the fill light of the detail channel, and the fill light of the panoramic channel to turn off later than the fill light of the detail channel, thereby optimizing the influence of the fill light of the detail channel on the panoramic channel when the monitoring areas overlap, so that the effective information monitored by the two channels of the camera can be retained to the maximum extent, and the image light and dark contrast phenomenon is reduced.

[0088] For example, Figure 4 This is another flow chart of dual-channel camera fill light control provided by the second embodiment of the present application. Figure 4 As shown, step one: record the fill light intensity and fill light angle of the fill light of the panoramic channel and the fill light of the detail channel. Step two: perform scene calibration and establish a mapping relationship between the image coordinates and the gimbal coordinates between the two channels. Step three: After the calibration is completed, the relative positions of the monitoring screens of the two channels are obtained according to the current gimbal coordinates of the detail channel. Furthermore, based on the data of the fill light area of ​​the detail channel, the relative position of the fill light area in the panoramic picture after the detail fill light is turned on is obtained. Step four: The processor determines whether the panoramic picture will be affected after the detail fill light is turned on. If there is no impact, each channel adopts its own default exposure and fill light strategy, which is independent of each other; if there is an impact, it switches to the new exposure and fill light control strategy, and the two channels synchronously control the fill light of the panoramic channel.
