Based on application environment and intelligent door lock presented hereinbefore, each reality of the application is specifically described below in conjunction with attached drawing Apply example.

Referring to Fig. 4, the method flow diagram of the method controlled for a kind of intelligent door lock that one embodiment of the application provides, this Embodiment provides a kind of method of intelligent door lock control, and the intelligent door lock includes camera, this method comprises:

Step S110: it whether there is target object within the scope of the pre-determined distance of detecting distance intelligent door lock.

Wherein, it should be noted that the target object in the embodiment of the present application can be the object with live biometric Body, for example, target object can be people.And it should be noted that if with the development of technology, intelligent door lock be for pet or its What allogene was specially arranged, then target object can be pet or other biological, the type of target object is not limited thereto.

It optionally, will be taking human as target object to intelligent door lock control provided by the embodiment of the present application in the embodiment of the present application The method of system is illustrated.

As a kind of mode, pre-determined distance range may include the target object that the camera of intelligent door lock can scan Horizontal distance (for example, it may be 0.4 meter~1.2 meters) apart from intelligent door lock, i.e. target object are apart from door where intelligent door lock The horizontal distance of (installing the door of intelligent door lock), for example, it is assumed that intelligent door lock can be with the face of the people within 3 meters of scanning distance door Portion's image carries out recognition of face in turn, then pre-determined distance range can be understood as 0-3 meters at this time.Alternatively, It may include the scanning area altitude range of the camera of intelligent door lock.For example, if camera can scan height be 1.2 meters- The face image of 1.8 meters of people, then in such cases, the scanning that pre-determined distance range can be understood as 1.2 meters -1.8 meters is high Spend range.

It should be noted that in order to further enhance the safety of intelligent door lock identification, it is default in the embodiment of the present application Horizontal distance and intelligence of the target object that the camera that distance range can be intelligent door lock can scan apart from intelligent door lock The combination of the scanning area altitude range of the camera of energy door lock.It is understood that by convex lens imaging principle it is found that mesh The distance for marking object distance intelligent door lock is different, formed image it is of different sizes.Optionally, if only passing through taking the photograph for intelligent door lock Horizontal distance of the target object that can be scanned as head apart from intelligent door lock unlocks to recognition of face, it would be possible that It will lead to some criminals to attempt to carry out illegal unlock and making repeated attempts position with a distance from door, for example, illegally Molecule copies the face combination aforesaid way of owner to attempt illegally to enter using any special measures.And it is alternatively possible, it is for industry Me is led, if height is higher, the face image that may be scanned at all in set above-mentioned horizontal distance less than owner of standing, or Person is to scan not cause to unlock entirely to take a long time, and influences user experience.

Correspondingly, if only being opened by the scanning area altitude range of the camera of intelligent door lock recognition of face Lock, then some criminals still may by from door a little further or more closely be imaged to obtain different height and making repeated attempts Face image so that identify entrance, or cause some misrecognitions, for example, when the B door someone on A opposites comes out, this People will only go out, and be not intended to out A, then in this case, if the B people institute station locations come out just reach A Intelligent door lock camera scanning area altitude range when, be likely to result in misrecognition, cause intelligent door lock mistake do not know Not, electricity is consumed.

In order to overcome the above problem, the camera of the intelligent door lock in the embodiment of the present application be can detecte apart from intelligent door lock Pre-determined distance within the scope of whether there is target object.As a kind of mode, the camera that can detecte intelligent door lock can be swept The scanning area altitude range of the camera of horizontal distance and intelligent door lock of the target object retouched apart from intelligent door lock is full It whether there is target object when within the scope of the respective pre-determined distance of foot.In this case, as an implementation, it can be Within the scope of the horizontal distance of first detecting distance intelligent door lock whether there is target object, in case of presence, then go detection away from From whether there is target object within the scope of the preset height of intelligent door lock, and then carry out subsequent judgement.By first judging apart from intelligence Can door lock horizontal distance range whether meet pre-determined distance range can to avoid illegal person malice identify, then by judge away from The flexibility of camera acquisition facial image can be promoted from whether there is target object within the scope of the preset height of intelligent door lock, Increase the coverage area of camera scanning.For example, preset horizontal distance range can be set to 0.3 meter.It should be noted that Preset height position is still first identified with the presence or absence of target object for first identifying within the scope of horizontal distance when intelligent door lock identification Sequence in range with the presence or absence of target object can be set according to actual needs not as restriction.

As a kind of mode, intelligent door lock can judge either with or without people by the first human body sensor close to door lock. Wherein, the first human body sensor can be passive infrared sensor.Specifically, passive infrared sensor can be real-time Detect the heat radiation variation in the three-dimensional prevention spatial dimension of the preset level distance range of intelligent door lock, when someone close to when, Passive infrared sensor can issue alarm, while someone's signal being sent to the control module of intelligent door lock, when door lock control When molding block judges that the horizontal distance of the signal distance intelligent door lock of human body meets pre-determined distance range, the scanning of camera is opened Function.It may be implemented to save the electricity of intelligent door lock and the scanning duration of camera, and then save power consumption.

Optionally, if someone's close door lock within the scope of preset horizontal distance, then intelligent door lock can be further Judge the preset height position apart from intelligent door lock with the presence or absence of human body by the second human body sensor.Wherein, the second people Body induction sensor can be active inductive pick-up.In this manner, when have human body signal by it is preset away from It, can be with initiative alarming, then control module can be adjusted according to alarm signal when preset height position range from intelligent door lock The image-capture field of camera.

Further, it is to be understood that for the intelligent door lock with face identification functions, the people on door lock can be passed through Face camera collection image, then does recognition of face.However, the field angle due to camera is related to distortion, i.e., field angle is got over Greatly, distortion may also will increase accordingly, and the accuracy rate and recognition speed for increasing and will affect recognition of face that distort, thus for Intelligent door lock class product including face identification functions it is too big to identify that the field angle of the camera of face cannot accomplish, for example, such as Recognition of face unlocking is done in the position from 30~40 centimeters of door in fruit people station, and the too high people of height needs to bend over so that face is being taken the photograph As head visual angle center, the partially short people of height can not recognize complete image, lead to the pickup area of camera acquisition facial image It is limited.

Therefore, to solve the above-mentioned problems, the embodiment of the present application will adjust the figure of camera according to above-mentioned testing result As acquisition range, it is described in detail below:

Step S120: if it exists, the image-capture field for adjusting the camera is adapted to the target object.

Wherein, when image-capture field refers to that intelligent door lock opens face identification functions, camera scanning face is swept Retouch range.It is understood that the user of different heights corresponds to different image-capture fields, therefore, in order to adapt to different bodies Image Acquisition of high user when using the face identification functions of intelligent door lock, the embodiment of the present application can be apart from intelligent door There are in the case where target object (such as people) within the scope of the pre-determined distance of lock, the image-capture field and target of camera are adjusted Object fits identify in order to acquire the biological information of target object for intelligent door lock.

As a kind of mode, it can be determined that whether the height of human body falls in the image-capture field of preset camera It is interior, the image-capture field of camera is then adjusted according to judging result.In the present embodiment, the Image Acquisition model of camera is adjusted The mode enclosed can there are many kinds of.

Optionally, for example, the image-capture field of adjustment camera may include the direction for adjusting camera, adjustment camera shooting The image scanning duration of head and the scanning area etc. for adjusting camera, do not illustrate, and do not constitute to this programme one by one herein Restriction.

Wherein, as a kind of mode, intelligent door lock in the present embodiment can be known according to the face of the user of different heights Other demand, first by camera to certain direction (such as can be upward sliding, slide downward, sliding to the left appropriate or Sliding etc. to the right appropriate) sliding or mobile, the image-capture field of camera is then adjusted again.For example, when detecting certain One people's height is too high and when face area can not be recognized, can be first by camera upward sliding a certain distance, so The direction of camera is rotated up again afterwards, the face area for allowing to scan to the higher face of height realizes recognition of face It unlocks.It should be noted that with the development of technology, the camera of intelligent door lock can also to the left or turn right appropriate Distance to increase the scanning range of face, while increasing security performance.

For example, it is assumed that people station is in side of the door far from installation door lock, then in this case, camera can be It detects after human body signal to the left or the appropriately distance that turns right is to scan the face image of the human body.If the people is just The user often to enter, then normally unlocking after then identifying successfully, in order to which the old man of some legs and feet inconvenience may need to help door Side in the case where also can normally unlock and enter；And if the people is illegal user, intelligent door lock camera to the left or to Right-hand rotation is moved after angle appropriate in the case where recognition of face mistake, alarm signal can be issued, to prevent criminal from hiding in door Side stalk the user to enter in the case where light is faint, and then promote security performance.

It is adapted to by adjusting the image-capture field of camera with target object, can satisfy the user of more different heights To the use demand of the recognition of face unlocking function of intelligent door lock, increase the scanning coverage area of camera.

Below by taking Fig. 5 as an example, brief exemplary illustration is carried out to above content:

As shown in figure 5, for the working principle flow diagram of intelligent door lock in a specific application scenarios.Intelligent door lock packet It includes the human body sensor (can be passive type PIR Sensor here) being arranged in above door lock, be arranged in below door lock Human body sensor (can be active PIR Sensor here), single-chip microcontroller and camera rotary electric machine.Under door lock The human body sensor of side is for whether there is human body signal in the preset level distance range of distance of reaction door lock, if deposited In human body signal, then will be by human body signal reporting to single-chip microcontroller, then by the human body sense above MCU driving door lock The scheduled height and position of inductive sensing device detecting distance intelligent door lock whether there is human body signal, then be driven according to judging result The rotation of camera rotary electric machine is to realize that the image-capture field for adjusting camera is adapted to target object.Optionally, specifically How will be described in detail in subsequent embodiment according to the adjusting that judging result carries out.

For example, it is assumed that human height's range that camera can scan originally is the face of 1.1 meters of -1.6 meters of heights, it is existing At 1.72 meters of the height for having a people, then adjustable camera is rotated up at this time, then the Image Acquisition of camera Range will also change, for example, becoming 1.25 meters -1.85 meters.

Step S130: if it does not exist, then the camera is not adjusted.

It is understood that if being not detected within the scope of the pre-determined distance of intelligent door lock, there are target objects, then The image-capture field that camera will not be adjusted is adapted to target object, so as to avoid mistuning section bring function from consuming Damage, and then save resource.

A kind of method of intelligent door lock control provided in this embodiment, passes through the pre-determined distance model of detecting distance intelligent door lock With the presence or absence of target object in enclosing, and if it exists, the image-capture field for adjusting camera is adapted to target object, in order to acquire The biological information of target object is identified for intelligent door lock.Whether deposited within the scope of pre-determined distance by judging intelligent door lock In target object, the image-capture field for then adjusting camera is adapted to target object, to acquire the biology of target object Characteristic information is identified for intelligent door lock, increases the coverage area of camera scanning, and then promote user experience.

Referring to Fig. 6, the method flow diagram of the method controlled for a kind of intelligent door lock that another embodiment of the application provides, The present embodiment provides a kind of methods of intelligent door lock control, and the intelligent door lock includes camera, this method comprises:

Step S210: it whether there is target object within the scope of the pre-determined distance of detecting distance intelligent door lock.

Step S220: if it exists, judge the height of the target object.

Optionally, the pre-determined distance range in the present embodiment can be understood as the preset level apart from intelligent door lock apart from model It encloses, i.e. the ground level linear distance of position where target object and the position of door.As a kind of mode, distance is being detected There are in the case where target object within the scope of the pre-determined distance of intelligent door lock, the height of target object can be further judged.Its In, the height of target object can be understood as the height of target object, the i.e. height of human body.

As a kind of mode, the image-capture field of camera can be preset, by the image-capture field of camera Minimum value as intelligent door lock preset height position (or using the average value of the image-capture field of camera as intelligence The preset height position of door lock, it should be noted that the preset height position of intelligent door lock can be set according to the actual situation Fixed or adjustment actual value size, herein not as restriction), then it is understood that can be by judging apart from intelligent door The preset height position of lock realizes the height judgement to target object with the presence or absence of target object, is described in detail below:

As shown in fig. 7, as a kind of mode, step S220 may include:

Step S221: if there are the target objects for the preset height position apart from the intelligent door lock, determine the mesh The height for marking object is higher than preset height.

As a kind of mode, preset height position can be detected by the second human body sensor and believed with the presence or absence of human body Number, to judge whether there is target object.Optionally, in this case, if detecting human body signal, indicate away from There are target objects for preset height position from intelligent door lock, then can be determined that the height of target object is higher than preset height.

Step S222: if the preset height position apart from the intelligent door lock does not have the target object, described in judgement The height of target object is not higher than preset height.

Optionally, if not detecting human body signal, indicate that the preset height position apart from intelligent door lock is not deposited In target object, it is possible to be the target object height it is too short, can also be with for example, it may be possible to be child or other biological Although being that the target object is in the scanning range of camera, scanning is only local face image, then in this feelings Under condition, it is possible to determine that the height of target object is not higher than preset height.

Above content is illustratively illustrated by taking Fig. 8 as an example below:

As shown in figure 8, to judge that the preset height position apart from intelligent door lock whether there is the exemplary diagram of target object.Figure H in 8 indicates the height of target object 30, and H indicates the preset height position of intelligent door lock 10, and 20 indicate pre-determined distance range, A, b indicates the image acquisition region of camera 40, and θ indicates the vertical direction field angle of camera 40, the second inductive pick-up 70 For judging at the preset height position H apart from intelligent door lock 10 with the presence or absence of human body signal.Optionally, if judgement distance intelligence There are human body signals at the preset height position H of door lock 10, then can be determined that the height of target object 30 is higher than intelligent door lock 10 preset height position H (h2 as shown in Figure 8)；And judge not deposit at the preset height position H apart from intelligent door lock 10 In human body signal, then can be determined that the height of target object 30 is not higher than preset height position H (such as Fig. 8 of intelligent door lock 10 Shown in h1)

Step S230: it is based on judging result, adjusts the image-capture field of the camera and the height of the target object Degree adaptation.

Optionally, the relationship of the preset height position of the height and intelligent door lock of the target object obtained by judgement, can It is adapted to adjusting the image-capture field of camera with the height of target object, and then increases the flexibility and intelligence of camera scanning Energy property, promotes user experience.It is described in detail below:

As shown in figure 9, as a kind of mode, step S230 may include:

Step S231: the state orientation of the camera is obtained.

Optionally, speed is identified after camera scans face in order to further increase the scanning range of camera and accelerate Degree can obtain camera in the case where determining the relationship of the preset height position of height and intelligent door lock of target object State orientation.

As a kind of mode, the state orientation of camera can be understood as the region of camera collection image relative to camera shooting The degree that height where head deviates upward or downward.For example, by taking Fig. 7 as an example, it is assumed that H is that the place height of camera (is as taken the photograph The height being directed to as the installation site of head), a, b are the image-capture field of camera, then can be by judging the figure of the side a, b The degrees of offset of camera is judged as the deviation angle of acquisition range.Optionally, if camera is greater than to the angle that the side a deviates The angle deviated to the side b, then can be understood as that the degree that camera is offset up is relatively large, i.e. the state orientation of camera For upward.Similar, if the angle that camera is deviated to the side a is less than the angle deviated to the side b, then can be understood as camera The degree offset downward is relatively large, i.e., the state orientation of camera is downward.

Step S232: the rotation direction of the camera is determined according to the height of the target object.

After obtaining the state orientation of camera, the rotation court of camera can be determined according to the height of target object To judging that camera is up to rotate or rotate down according to the height of target object.

In order to increase the image-capture field of camera, as a kind of mode, if the height of target object is higher than intelligent door The preset height position of the camera of lock, in such cases, if the state orientation of camera is not state (such as shape downward upward State), then can be upward in order to adjust the state orientation of camera by the rotation of camera towards being determined as rotating upward State；And if the state orientation of camera is state upward, then can no longer adjust, to save power consumption.

Alternatively, if the height of target object is not higher than the preset height position of the camera of intelligent door lock, In such cases, if the state orientation of camera is not state (such as state upward) downward, then camera can be turned Dynamic direction is determined as turning downward, in order to adjust the state orientation of camera as state downward；And if camera towards shape State is state downward, then can no longer adjust, to save power resources.

It is worth noting that, determining that the height of target object is not higher than preset height is by the default height in intelligent door lock Degree position is not detected what judgement in the case where human body signal obtained, then be in the child of growth stage for some heights It says, the height independently opened the door that height may not up to be set, and again than the body of other children that cannot independently open the door Gao Yaogao, then in such case, it will be understood that, human body signal is not detected in the preset height apart from intelligent door lock When determines the height of target object, and there may be erroneous judgements not higher than preset height, i.e., the people for really having enabling demand are kept off in door Outside.

So in order to improve this problem, if the height of target object is not higher than preset height, in the court for determining camera To state be downward state when, judgement can be continued and be at the corresponding position height of state downward with the state orientation of camera With the presence or absence of target object.Optionally, if it is present, the biological information for then continuing to acquire target object is used for intelligence Door lock identification.By the way that multiple judgement is arranged, the flexibility of intelligent door lock judgement can be enhanced, promote user experience.

Step S233: adjust the camera based on it is described rotation towards rotating object angle to the target object Height is adapted to.

Optionally, as the improvement of people's living standards, the height of present people is generally higher, some students at primary school Height even can achieve one meter six or one meters seven etc..So, in order to which the face for meeting the user of more higher heights is known Camera can be needed the angle rotated to divide by other function use demand.Specifically, can be adjusted as a kind of mode Whole camera is extremely adapted to the height of target object based on above-mentioned rotation towards rotating object angle.Wherein, target angle is to take the photograph As the angle that head needs to rotate, the target angle being rotated up can be needed to be expressed as the first sub-goal angle camera, it will Camera needs the target angle rotated down to be expressed as the second sub-goal angle, and optionally, the first sub-goal angle can be Camera direction and the angle between horizontal line, the second sub-goal angle can be camera direction and the folder between horizontal line Angle.Optionally, the angle of rotation can be more angles with more than two.

So be used as a kind of mode, adjustable camera be based on rotation direction, be rotated up the first sub-goal angle or It rotates down the second sub-goal angle to be extremely adapted to the height of target object, wherein the first sub-goal angle is greater than the second specific item Mark angle.It should be noted that the numerical value of the first sub-goal angle and the numerical value of the second sub-goal angle in this programme simultaneously Not as restriction, the angle that can be supported with camera.It, can be with by setting the biggish sub-goal angle being rotated up Safe application performance is promoted, can be to avoid in some cases, when adult is doing work, child opens the door away alone, mentions Rise specific user's use demands.
