Description
Technical Field
The present invention relates to the field of image processing technologies, and in particular, to a light supplement method and apparatus, a computer apparatus, and a readable storage medium.
Background
Under the night environment, the existing image acquisition equipment usually needs to supplement light to a monitored area first, and then can realize the identification of a target object in the monitored area.
Currently, the following two light supplement schemes are often adopted to monitor a target object. The first is an infrared light supplement scheme, specifically, an image acquisition device is switched to an infrared light supplement mode, and an infrared lamp is used for supplementing light to a target object (such as a person), so that a black-and-white image is obtained. Although the whole supplementary lighting process is not easy to cause discomfort to the eyes of the target object, since the existing image recognition algorithm is usually processed based on a color image, the black and white image obtained under the scheme increases the complexity and accuracy of the subsequent image processing.
The second is a visible light supplementary lighting scheme, specifically, a monitored area is continuously supplemented with visible light at night, although the acquired image is a color image and is convenient for subsequent image processing, the eyes of the target object are easily discomforted by the visible light, and light pollution is caused to other areas except the target object in the monitored area.
Therefore, the conventional light supplement scheme cannot take the influence of the image processing precision and the light pollution into consideration.

In the embodiment of the present invention, the light supplement method may be specifically applied to an image acquisition system, where the image acquisition system includes an infrared image acquisition module, an infrared light supplement module, a visible light image acquisition module, an image processing module, and the like. The infrared light supplementing module is used for performing infrared light supplementing on the monitored area in real time; the infrared image acquisition module is specifically used for acquiring and obtaining an infrared image for a monitored area in real time; the image processing module is used for analyzing the infrared image and determining the attribute information of the target object in the infrared image so as to determine the target object which accords with the preset attribute information; then, the image processing module controls the visible light supplementary lighting module to supplement light for the target object which accords with the preset attribute information; then, a visible light image of the target object aiming at the preset attribute information is obtained by a visible light image acquisition module; then, the obtained visible light image is analyzed and processed by the image processing module.
In the embodiment of the present invention, the image capturing system may be a dual-camera structure, in which one group of lenses and image sensors captures infrared images, and the other group of lenses and image sensors captures visible light images. The image acquisition system can also be a light splitting structure, specifically, light acquired by the same lens is split into one path of infrared light and one path of visible light according to wavelength by light splitting devices such as a prism and the like, and the infrared light and the visible light are respectively acquired by corresponding image sensors. The image acquisition system can also adopt a structure of a single lens and a mixed pixel image sensor, and specifically, the pixels of the image sensor are formed by mixing visible light sensing pixels and infrared light sensing pixels. In a specific implementation process, the acquired infrared image and the visible light image have a determined position mapping relation.
In addition, in the embodiment of the present invention, each module included in the image capturing system may also be named by other names, and all modules capable of implementing corresponding functions are within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the invention provides a light supplement method, including:
s101: acquiring and obtaining an infrared image aiming at a monitored area;
s102: acquiring attribute information of each target object in M target objects in the infrared image, and acquiring M pieces of attribute information in total, wherein M is a positive integer;
s103: determining N target objects which accord with preset attribute information from the M attribute information, wherein N is a positive integer not greater than M;
s104: and controlling visible light to supplement light for each target object in the N target objects.
In the specific implementation process, the specific implementation process of step S101 to step S104 is as follows:
firstly, infrared light supplement is carried out on a monitored area, and an infrared image aiming at the monitored area is acquired and obtained. Then, analyzing the infrared image to obtain attribute information of each target object in M target objects in the infrared image, and obtaining M pieces of attribute information in total, wherein M is a positive integer. In a specific implementation process, the attribute information may specifically be at least one of size, human body attribute, clothing attribute, and vehicle attribute of the target object in the image. Wherein each attribute information may be a set including a plurality of features. For example, the human body attribute comprises gender and age, the clothing attribute comprises hat, skirt and shoes, and the vehicle attribute comprises bus, car and bicycle. As a specific example, M is 3, and there are A, B, C target objects in the infrared image, where the attribute information of the target object a is "middle age, male, optical head, walking", the attribute information of the target object B is "child, female, twisted braid, toy car", and the attribute information of the target object C is "young, female, long hair, car".
Then, N target objects which accord with preset attribute information are determined from the obtained M pieces of attribute information. Wherein N is a positive integer not greater than M. In a specific implementation process, the preset attribute information may be specifically set manually by a user according to actual needs, or may be set by a person skilled in the art in advance for an image acquisition system. Still taking the above example as an example, when the preset attribute information is "middle age, male, bald", the target object a is determined to be the target object conforming to the preset attribute information.
In the embodiment of the present invention, based on the attribute of the size of the target object in the image, the target object meeting the size requirement may be screened, for example, the target object with the size larger than a preset threshold may be screened, where the preset threshold may be a numerical value specifically set by a person skilled in the art according to an actual use habit of a user, and for example, the preset threshold is 10pixels × 10 pixels. Of course, the numerical value can also be manually set by the user according to needs, and the description is omitted here. Of course, those skilled in the art can set other attribute information than the above listed attribute information according to actual needs to implement the screening of the target object, and details thereof are not described here.
And then, controlling the visible light to supplement light for each target object in the N target objects. Still taking the above example as an example, the visible light is controlled to fill the target object a with light. In a specific implementation process, if it is determined from the M attribute information that there are a plurality of N target objects that meet the preset attribute information, the N target objects may be supplemented with light by visible light, or each target object of the N target objects may be supplemented with light sequentially according to a preset sequence. The preset sequence may be a sequence preset by a person skilled in the art according to an actual use habit of a user, or may be a sequence manually set by the user, for example, light supplement is sequentially performed according to a height sequence from top to bottom, and then light supplement is sequentially performed according to a left-to-right sequence, and the like, which are not illustrated herein.
In order to implement accurate light supplement for a target object in the embodiment of the present invention, referring to fig. 2, in step S103: after determining N target objects meeting preset attribute information from the M attribute information, the method further includes:
s201: acquiring behavior characteristic information of each target object in the N target objects, and acquiring N pieces of behavior characteristic information in total;
s202: determining N moments when visible light supplements each target object of the N target objects according to the N behavior feature information, wherein the moment when the visible light supplements a first target object of the N target objects corresponds to a first moment of the N moments;
s203: and when the current moment is the first moment, controlling visible light to supplement light for the first target object.
In the specific implementation process, the specific implementation process of step S201 to step S203 is as follows:
firstly, behavior feature information of each target object in N target objects is obtained, and N pieces of behavior feature information are obtained in total. Wherein the behavior feature information comprises at least one of orientation, posture, distance, movement speed and position. The behavior feature information of each target object may be a set of a plurality of behavior features. In a specific implementation process, the behavior feature information may be manually set by a user according to actual needs, or may be preset for an image acquisition system by a person skilled in the art. In a specific implementation, the orientation is used to characterize the orientation of the face of the target object, for example, the face of the target object is facing the image acquisition system; the posture is used for representing the current appearance and expression of the target object, for example, the current posture of the target object is sitting upright relative to the image acquisition system; for another example, the current posture of the target object is kneeling with one leg relative to the image acquisition system. The distance is used for representing the distance condition between the target object and the image acquisition system; the motion speed is used for representing the speed value of the target object. The position is used for representing the position information of the specific position of the target object. Of course, those skilled in the art can set other behavior feature information than the above listed behavior feature information according to actual needs to implement the screening of the target object, and details thereof are not described herein.
Then, according to the N behavior feature information, N times at which the visible light supplements each of the N target objects are determined, wherein a time at which the visible light supplements a first target object of the N target objects corresponds to a first time of the N times. And then, when the current moment is a first moment, controlling the visible light to supplement light to the first target object. That is to say, through analyzing the behavior characteristics of N target objects that accord with preset attribute information, and then confirm the moment that the visible light carries out the light filling to every target object in these N target objects, only need to carry out the light filling to corresponding target object again when corresponding moment arrives, whole process need not whole journey and carries out the light filling to target object to when avoiding eyes are uncomfortable, guaranteed the accurate light filling to target object.
Still taking the above example as an example, the behavior feature information of the target object a is obtained, and when it is detected that the current face of the target object a is directly facing the image acquisition system, the target object a is supplemented with visible light. In a specific implementation process, if a plurality of N target objects are provided, the time when the face of each target object is over against the image acquisition system can be determined, and the visible light is controlled at the corresponding time to supplement light for the corresponding target object. Of course, besides determining the light supplement time of each target object in the N target objects according to the face orientation, a person skilled in the art may also define the corresponding light supplement time when the behavior feature information of the N target objects is specific according to the actual usage habit of the user, and thus the description is omitted here.
In the embodiment of the present invention, referring to fig. 3, in order to improve the light supplement efficiency, in step S203: when the current time is the first time, after the visible light is controlled to supplement light to the first target object, the method further includes:
s301: acquiring and obtaining a first visible light image aiming at the first target object;
s302: and marking the current state of the first target object as a processed state, and controlling visible light to stop the light supplement of the first target object.
In the specific implementation process, the specific implementation process from step S301 to step S302 is as follows:
first, a first visible light image for a first target object is acquired. And then, marking the current state of the first target object as a processed state, and controlling the visible light to stop the light supplement of the first target object. That is, after the acquisition of the first visible light image of the first target is completed, the first target object is marked as a processed state, and then the light supplement and image acquisition are continuously performed on the first target object without visible light. In a specific process, the processed state may be a completed acquisition state, and after the first target object is in the processed state, the light supplement and the image acquisition of the first target object are continued without visible light until the first target object is lost. Still taking the above example as an example, after performing visible light supplementary lighting on the target object a, acquiring to obtain a visible light image for the target object a, marking the target object a in a processed state, and then performing visible light supplementary lighting and image acquisition on the target object a again is not needed.
In addition, in the specific implementation process, when the N target objects are a plurality of target objects including the first target object, the same processing can be performed on other objects except the first target object, and it is not necessary to continuously perform visible light supplementary lighting on each target object and image acquisition, so that discomfort to human eyes caused by continuous visible light supplementary lighting and light pollution to other objects in a monitored area are effectively avoided, and the service performance of the image acquisition system is improved while the supplementary lighting efficiency is improved.
In an embodiment of the present invention, in order to improve the targeted light supplement for the target object and further improve the light supplement efficiency, please refer to fig. 4, the method further includes:
s401: determining the area position of each target object in the N target objects in the monitoring area, and obtaining N area positions in total;
s402: and controlling visible light to supplement light for the target object at each of the N area positions.
In the specific implementation process, the specific implementation process from step S401 to step S402 is as follows:
firstly, determining the area position of each target object in the N target objects in a monitoring area, and obtaining N area positions in total; and then, controlling the visible light to fill in light of the target object at each of the N area positions. That is to say, after the target objects meeting the preset attribute information are screened out, targeted light supplement is performed on the target objects in each area position according to the position of each target object in the monitored area, so that a function of targeted light supplement according to the area positions is achieved, light supplement efficiency is improved, and meanwhile, waste of energy consumption is effectively reduced.
