Referring to fig. 1, an optional application scenario diagram of an IR-Cut-free video stream processing method according to an embodiment of the present application is shown. The IR-Cut-free video stream processing method can be applied to an intelligent door lock, and the intelligent door lock 10 can form an internet of things system with gateway equipment 53, terminal equipment 51, a server 52 and the like.
The terminal device 51 may be any device having communication and storage functions, such as: smart phones, desktop computers, notebook computers, tablet computers, or other intelligent communication devices with network connection functions. Server 52 may be a network access server, database server, cloud server, or the like. Optionally, the gateway device 53 may be set up based on a ZigBee protocol, and the intelligent door lock may be a device that is added to the gateway device 53 in advance, for example, the intelligent door lock may be a device in a suite to which the gateway device 53 belongs when leaving the factory; or may be a device that is subsequently connected to the gateway device 53 by user operation.
Optionally, a client capable of managing the intelligent door lock is installed in the terminal device 51, where the client may be an application client (such as a mobile phone APP) or a web client, which is not limited herein.
Alternatively, the smart door lock 10 may establish a network connection with the gateway device 53 based on the ZigBee protocol, thereby joining in the ZigBee network.
The intelligent door lock 10 and the terminal device 51 can be accessed to the Ethernet through the gateway device 53, and the gateway device 53 can be accessed to the server 52 through a wired or wireless communication connection mode. For example, the gateway device 53 and the terminal device 51 may store the acquired information in the server 52. Optionally, the terminal device 51 may also establish a network connection with the server 52 through 2G/3G/4G/5G, wiFi and so on, so as to obtain data issued by the server 52.
Optionally, the terminal device 51, the gateway device 53 and the intelligent door lock 10 may be in the same local area network, or may be in the same wide area network as the server 52. Wherein, when the terminal device 51 and the gateway device 53 are in the same local area network, the terminal device 51 can interact with the gateway device 53 and the intelligent door lock 10 connected to the gateway device 53 through a local area network path; interaction with the gateway device 53 and the smart door lock 10 connected to the gateway device 53 may also be through a wide area network path. When the terminal device 51 and the gateway device 53 are not in the same local area network, the terminal device 51 may interact with the gateway device 53 and the smart door lock 10 connected to the gateway device 53 through a wide area network path. The internet of things system can realize portal security remote monitoring, such as remote real-time viewing of monitoring video, recording of monitoring video, etc., through the intelligent door lock 10.
Referring to fig. 2 and 3, an optional structural schematic diagram of the intelligent door lock is shown, wherein the intelligent door lock 10 includes a main controller 11, an infrared (Infrared Radiation, IR) lens 13 connected to the main controller, an RGB lens 14, a flood lamp 15, a projection lamp 16, an infrared light-compensating lamp 17, and a display screen 18. Wherein the RGB lens 14 is used to capture video streams and then send to the display 18 for display. The RGB lens 14 adopts a dual-pass filter, which can pass 390nm (nanometer) -780nm visible light and 940nm infrared light, and needs to pass 940nm infrared lamp for light supplementing in night vision state. The IR lens 13 is used to capture video stream data for face recognition. The infrared light supplementing lamp 17 is used for supplementing light to the RGB lens in a night vision state, and the IR lens 13 is a single-pass filter and only passes 940nm infrared light. Floodlight 15 is used to supplement IR lens 13. The projector 16 is used to capture the stereoscopic video stream data after the IR lens 13 is dotted. In implementing portal security monitoring, the intelligent door lock 10 needs to process video streams to identify faces. In the embodiment of the application, two pieces of image data are needed for face recognition, and one piece is an infrared image, namely, the image data captured after the infrared lamp is turned on for light filling. The other is the depth map, i.e. the image data captured after the lens is dotted by turning on the projector 16.
The inventor discovers in the research that in the process of realizing the safety monitoring of a door, the known intelligent door lock performs face recognition in daytime, when a floodlight and a projection lamp are opened, 940nm infrared light can enter an RGB lens, so that the RGB lens can be reddened in a color image state, and the image can flash. In the night vision state, a black-and-white image may flash. When the known IR-Cut filter is added to solve the problem, the thickness of the intelligent door lock is too thick, the appearance setting of the door lock is affected, and the cost of the door lock is increased. In order to solve the problems, the application provides an IR-Cut free video stream processing method, which processes the working time period of face recognition through an algorithm in a software mode, for example, when a floodlight and a projection lamp are turned on, an infrared image and a depth image for face recognition are captured through an IR lens, a main controller switches an RGB lens to a sleep (sleep) mode, and discards an original video frame of the RGB lens, or compensates the reddish display of a display screen through the algorithm, or directly controls the display screen to not display in the time interval, so that the RGB lens cannot be exposed to the video frame of the video stream after the floodlight is turned on, and the problem of reddish display of the display screen is solved. When the IR lens picture taking is finished, the floodlight and the projector are turned off, the RGB lens enters a normal mode, and the RGB video stream is recovered.
Referring to fig. 4, an IR-Cut-free video stream processing method according to an embodiment of the present application includes, but is not limited to, S101 and S103, and is specifically described as follows:
s101, when the infrared lens is in a picture-picking mode, performing red-bias color development processing on acquisition and/or display of video stream data in the picture-picking mode period.
The infrared lens is in a pattern acquisition mode, namely a working mode of opening the floodlight and the projection lamp and acquiring an infrared pattern and a depth pattern for face recognition through the infrared lens. And performing red-bias color development processing on the acquisition and/or display of the video stream data acquired in the image acquisition mode of the infrared lens, wherein the red-bias color development processing is performed on the acquisition of the video stream data in the image acquisition mode, or the display of the video stream data in the image acquisition mode, or the red-bias color development processing is performed on the acquisition and display of the video stream data in the image acquisition mode.
The process of red-bias color development for the acquisition of video stream data in the image acquisition mode may be that when the infrared lens is in the image acquisition mode, the main controller switches the RGB lens to a sleep mode, and the RGB lens pauses the acquisition of video stream data, or discards the original video frame of the RGB lens; the processing of red-bias color development for the display of the video stream data in the image capturing mode can be that when the infrared lens is in the image capturing mode, the main controller compensates the red-bias display of the display screen through an algorithm, or can directly control the display screen not to display in the time interval.
S103, under the condition that the image acquisition mode of the infrared lens is determined to be ended, recovering a normal working mode for acquiring and/or displaying the video stream data.
The normal working mode is a working mode that after the floodlight and the projection lamp are closed, video streams are collected through the RGB lens and sent to the display screen for displaying. And after the image acquisition mode of the infrared lens is finished, recovering the normal working mode of acquiring and/or displaying the video stream data, namely stopping performing red-bias color development on the video stream data after the image acquisition mode of the infrared lens is finished.
In the above embodiment, when the infrared lens is in the image capturing mode, the video stream data in the face recognition working period is subjected to the red-bias color development processing, and when the infrared lens is used for capturing images, the floodlight and the projector are turned off, and the RGB lens enters the normal mode, so that the RGB video stream is recovered, the problem of red bias of the image can be avoided under the condition that an IR-Cut filter is not required, the thickness of the intelligent door lock can be effectively reduced, and the cost can be reduced.
In some embodiments, when the infrared lens is in the image capturing mode, the processing of red-out color cast processing on the capturing and/or displaying of the video stream data during the image capturing mode includes:
and controlling the RGB lens to stop acquiring video stream data during the image acquisition mode under the condition that the infrared lens is in the image acquisition mode.
One implementation scheme of performing red-bias color development processing on the acquisition of video stream data in the image acquisition mode period is that a main controller controls an RGB lens to stop acquiring the video stream data in the image acquisition mode period. For example, when the infrared lens is in the image capturing mode, the main controller controls the RGB lens to switch to the sleep mode, and the RGB lens entering the sleep mode suspends the acquisition of video stream data. When the infrared lens image acquisition is finished, the main controller controls the RGB lens to switch back to the working mode from the dormant mode, and video stream data are acquired and sent to the display screen for display.
In the above embodiment, by controlling the RGB lens to switch to the sleep mode when the infrared lens is in the image capturing mode, and switching back to the working mode after the image capturing mode of the infrared lens is finished, the video frames of the video stream after the floodlight and the projection lamp are turned on can be avoided when the RGB lens is exposed to the image capturing mode of the infrared lens, the problem of reddening in display can be avoided without using an IR-Cut lens, the stacking design thickness of the lens module is reduced, better appearance design and stacking space are provided, the cost of the lens module is reduced, and the image capturing mode of the infrared lens and the working mode of the RGB lens for capturing video stream data are staggered with each other, so that the power consumption can be saved.
In some embodiments, the controlling the RGB lens to stop acquiring video stream data during the picture taking mode includes:
Controlling an RGB lens to switch to a sleep mode in the image acquisition mode period, wherein the RGB lens stops acquiring video stream data in the sleep mode; or (b)
Controlling an RGB lens to switch to a sleep mode in the image capturing mode period, wherein the RGB lens stops outputting video stream data to a display module in the sleep mode; or (b)
And when the RGB lens is controlled to output video stream data to the display module, discarding the video stream data acquired in the image acquisition mode period.
The RGB lens may be preset to stop collecting video stream data in the sleep mode, or preset to stop outputting video stream data to the display module in the sleep mode. The main controller controls the RGB lens to switch to a sleep mode when the infrared lens enters a picture-taking mode, and the RGB lens stops collecting video stream data in the sleep mode, so that video frames of video streams collected after the floodlight and the projection lamp are started when the RGB lens is exposed to the infrared lens and is in the picture-taking mode can be avoided; the main controller controls the RGB lens to switch to a sleep mode when the infrared lens enters a picture-taking mode, and stops outputting video stream data to the display module, so that the display screen can not display or retain the prior display data and can display the red problem.
Optionally, the main controller controls the RGB lens to stop acquiring video stream data during the image capturing mode, or controls the RGB lens to discard video stream data acquired during the image capturing mode when outputting video stream data to the display module after the infrared lens enters the image capturing mode, at this time, the display screen may not display or retain previous display data, so that the red bias problem may also be displayed.
In the above embodiment, when the RGB lens is in the image capturing mode, the method of stopping capturing video stream data, stopping outputting captured video stream data or discarding captured video stream data is controlled, and the problem of reddening in display is avoided by controlling the capturing of video stream of the RGB lens, so that the IR-Cut lens is not required, the stacking design thickness of the lens module is reduced, and the cost of the lens module is reduced.
In some embodiments, when the infrared lens is in the image capturing mode, the processing of red-out color cast processing on the capturing and/or displaying of the video stream data during the image capturing mode includes:
When the infrared lens is in the image capturing mode, the control display module is used for obtaining video stream data of the RGB lens in the image capturing mode, and processing of the difference frame is ignored.
The difference frame refers to a Predictive-Picture (P-frame) in a coded stream of video stream data. The difference frame is typically located after the key frame (I-frame) and the encoded image of the amount of transmission data is compressed by exploiting the temporal redundancy information that will be lower than the previously encoded frame in the image sequence. The difference frame needs to reference the previous key frame or bi-directionally predicted interpolated encoded frame to form the full image. In this embodiment, one of the implementation schemes of performing the red-bias color rendering processing on the display of the video stream data in the image capturing mode is that when the main controller controls the display module to acquire the video stream data of the RGB lens in the image capturing mode, the processing of the difference frame is ignored, and at this time, the display screen only retains the key frame of the video stream data acquired by the RGB lens in the image capturing mode, thereby greatly reducing the problem of red-bias display.
In the above embodiment, when the infrared lens is in the image capturing mode, the display module is controlled to not make a reference to the P frame data of the video stream data encoded stream output by the RGB lens, and the video stream data of the P frame data is removed, so that the problem of red display can be greatly reduced or eliminated, the IR-Cut lens is not required, the stacking design thickness of the lens module can be reduced, and the cost of the lens module is reduced.
In some embodiments, when the infrared lens is in the image capturing mode, the processing of red-out color cast processing on the capturing and/or displaying of the video stream data during the image capturing mode includes:
And under the condition that the infrared lens is in a graph acquisition mode, the display module is controlled to stop displaying during the graph acquisition mode.
The implementation scheme of performing the red-bias color development processing on the display of the video stream data in the image capturing mode period can also be that the main controller controls the display module to stop displaying in the image capturing mode period of the infrared lens. For example, when the infrared lens is in the image capturing mode, the main controller controls the display module not to display the monitoring image. And after the infrared lens image acquisition is finished, the main controller controls the display module to resume display.
In the above embodiment, the display module is controlled to stop displaying the video stream data currently obtained from the RGB lens when the infrared lens is in the image capturing mode, and the video stream data is restored after the image capturing mode of the infrared lens is finished, so that the problem of reddening display can be avoided on the premise that the IR-Cut lens is not required to be used.
In some embodiments, when the infrared lens is in the image capturing mode, the processing of red-out color cast processing on the capturing and/or displaying of the video stream data during the image capturing mode includes:
Under the condition that the infrared lens is in a picture-picking mode, if the color of a target object contained in video stream data collected in the picture-picking mode is not red, separating and removing infrared signal components in the video stream data so as to compensate for red bias color development of a display module in the picture-picking mode period;
And if the color of the target object contained in the video stream data acquired in the image acquisition mode comprises red, separating and removing infrared signal components of the video stream data except for the target object area so as to compensate for red bias color development of the display module in the image acquisition mode.
The implementation scheme of performing the color cast red color rendering processing on the display of the video stream data in the image capturing mode can also be that the main controller controls the display module to perform color cast red color rendering compensation on the video stream data acquired by the RGB lens in the image capturing mode of the infrared lens so as to solve the problem of color cast red. The offset red color compensation may be to calculate an infrared signal component in the video stream data and separate and remove the infrared signal component in the video stream data. The infrared signal component in the video stream data may be calculated based on pixel values for each pixel point of the video frame in the video stream data. Further, when the video stream data is subjected to the red bias color development compensation, whether the color of the target object contained in the acquired video stream data comprises red or not is further judged, when the target object comprises red, a target object area which is red is reserved, and only infrared signal components in an image area outside the target object area are separated and removed, so that the accuracy of the red bias color development compensation is improved.
Taking a target object as an artificial example of wearing a red hat, the main controller judges whether the color of the target object contained in video stream data acquired by the infrared lens in a picture acquisition mode contains red or not, determines that the hat part in an imaging area of the target object is the color of the target object, separates the imaging area of the hat without making red bias color compensation, and calculates, separates and removes infrared signal components from the image area part outside the imaging area of the hat. It should be noted that the imaging area of the target object may include a plurality of red areas, and if the target object is a person wearing a red hat and wearing red clothes, the imaging area of the clothes is also separated and does not undergo red color bias compensation.
