Detailed Description
For the purposes of promoting an understanding of the principles and advantages of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same.
It is noted that unless otherwise defined, technical or scientific terms used in one or more embodiments of the present disclosure should be taken in a general sense as understood by one of ordinary skill in the art to which the present disclosure pertains. The use of the terms "first," "second," and the like in one or more embodiments of the present description does not denote any order, quantity, or importance, but rather the terms "first," "second," and the like are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
One or more embodiments of the present specification provide a conference personnel scheduling method based on millimeter wave radar detection, as shown in fig. 1, the method including:
and step 101, detecting all targets in the conference room through a millimeter wave radar to obtain radar detection information.
The millimeter wave radar is a radar working in millimeter wave band detection, has the characteristics of small volume, light weight and high spatial resolution, and simultaneously has the advantages of being not easily affected by environment, strong in anti-interference capability, long in detection distance (the detection of human bodies can reach 8 to 10 m) and large in detection angle. The working principle is as follows: radio waves (radar waves) are transmitted, echoes are received, and position data of the object is measured based on a time difference between transmission and reception. Millimeter Wave (MMW) refers to electromagnetic waves with a length of 1-10 mm, and the corresponding frequency range is 30-300 GHz. According to the wave propagation theory, the higher the frequency, the shorter the wavelength, the higher the resolution, the stronger the penetrating power, but the larger the loss in the propagation process, the shorter the transmission distance; conversely, the lower the frequency, the longer the wavelength, the stronger the diffraction power and the farther the transmission distance. Therefore, compared with microwaves, the millimeter wave has high resolution, good directivity, strong anti-interference capability and good detection performance; compared with infrared, the millimeter wave has reduced atmospheric attenuation, better penetrability to smoke and dust and less influence from weather; these characteristics determine that millimeter wave radars have all-weather operating capabilities throughout the day.
In this embodiment, the millimeter wave radar is disposed at a position in the conference room that can cover the entire conference room, and then the target in the conference room is detected by the millimeter wave radar. As shown in fig. 2, in a specific embodiment, the millimeter wave radar module 1 is embedded directly above the conference integrated machine 2, and at this time, the millimeter wave radar module 1 can realize detection of the target in the whole conference room.
And 102, determining moving targets in all targets according to the radar detection information, and calculating the reflection area of the moving targets.
In this embodiment, the moving object may be a human body, and if the object is a human body, it may not always move. The reason is that: if the target is a human body, the human body cannot be still at all times and has a motion state. For example, even if a participant has found a seat to sit down, he will not get up or move position for a long period of time, but he will not be completely stationary, there will be at least a small range of movement over a certain time range, such as moving a finger arm, adjusting a sitting position, etc. Therefore, the moving target is detected to be in a moving state, or the moving target is detected to be in a static state when the detection is started, and the static target is in the moving state within a preset time range, so that the moving target can be judged. If the target is still and the rest time exceeds the preset time range, judging that the target is an object.
The moving object is not necessarily a human body, for example, an object pushed by a human body at all times, but is not a human body, so that further determination of the moving object is required. In this embodiment, the reflection area of the moving object is calculated, and the human body and the object in the moving object are distinguished based on the reflection area of the moving object.
And step 103, determining the human body in the moving object according to the reflecting area of the moving object.
And 104, acquiring personnel detection information in the conference room according to the radar detection information and the determined human body in the moving target, and recommending conference personnel arrangement according to the personnel detection information.
In this embodiment, radar detection information of all targets in a conference room is obtained by detecting with a millimeter wave radar, then moving targets in all targets in the conference room are selected based on the radar detection information, then human bodies in the moving targets are selected according to the calculated reflection areas of the moving targets, finally the radar detection information detected with the millimeter wave radar and the human bodies obtain personnel detection information of personnel in the conference room, and recommendation of meeting personnel arrangement is performed based on the personnel detection information. Human body identification is performed through the millimeter wave radar, and reasonable seating arrangement is performed on personnel in the conference room based on information corresponding to the human body, so that conference room resources are utilized more reasonably. Meanwhile, as the millimeter wave radar has stronger detection capability, when equipment such as a conference machine is made of nonmetal materials such as plastics and wood, the equipment does not need to be perforated like the traditional detection scheme, the appearance of the equipment can be better protected, and the damage to the appearance of the equipment is reduced. The detection of the human body can be realized without a camera, which is beneficial to the protection of the privacy of the user.
Optionally, determining moving targets in all targets according to the radar detection information in step S102 includes:
step S201, controlling the millimeter wave radar to uninterruptedly transmit signals to all targets, and receiving return signals reflected by all targets.
Step S202, judging whether the return signal of any object is changed.
Step S203, if yes, determining the target as a moving target.
In this embodiment, the transmitting module of the millimeter wave radar may be controlled to continuously transmit electromagnetic waves, the detected target generates an echo, the receiving module of the millimeter wave radar receives a return signal of the target, and if the received return signal changes, it is determined that the detected target is in a moving state, that is, the detected target is a moving target.
Optionally, the calculating the reflection area of the moving object in step S102 includes:
step S301, radar signal reflection quantity and target distance are obtained according to the radar detection information.
Step S302, determining a reflection area of the moving target according to the radar signal reflection amount, the target distance and the human body reflectivity.
Wherein, in step S302, determining the human body in the moving object according to the reflection area of the moving object includes:
step S401, determining whether the reflection area of the moving object is within a preset first threshold range.
Step S402, if yes, judging that the moving object is a human body.
Step S403, if not, determining that the moving object is an object.
In this embodiment, the radar signal reflection amount, the target distance and the target angle are information that can be directly detected by the millimeter wave radar, that is, the radar detection information includes the radar signal reflection amount, the target distance and the target angle. The radar signal reflection is determined by the reflectivity of the target to the radar, the reflection area and the distance between the radar, and the reflectivity of different objects is different, and the specific reflectivity is shown in fig. 3. Since the radar signal reflection amount has been measured and the human body reflectivity and the distance between the target and the radar have been measured, the target can be equivalent to the human body to obtain the reflection area. Comparing the calculated reflection area of the moving object with a preset first threshold range, and if the calculated reflection area meets the first threshold range, namely, the reflection area is between a preset upper limit value and a preset lower limit value, proving that the moving object is a human body; if the first threshold is not met, that is, the reflection area is larger than a preset upper limit value or smaller than a preset lower limit value, the moving target is an object.
In this embodiment, if an object is pushed into the conference room by a participant, the object is determined to be a moving target after the operations of steps S201-S203 are performed. After the operations of steps S301 to S302 and steps S401 to S403 are performed, if the value of the reflecting area of the calculator exactly accords with the reflecting area range of the human body, it may be misjudged as the human body, and the judgment error caused by the special situation may affect the subsequent arrangement of the member personnel. However, it is not possible for the object to move all the time, it must have a moment of rest. Therefore, in this embodiment, after the moving object is determined to be a human body in step 402, the method further includes:
step S501, determining whether the moving object is stationary again and the stationary time exceeds a preset second threshold. After the moving object is judged to be a human body, whether the object is stationary again is further judged, and if so, whether the stationary time exceeds a preset second threshold value is further judged.
Step S502, if yes, re-judging the moving object as an object.
Step S503, if not, determining that the moving object is a human body.
The conference personnel arranging method based on millimeter wave radar detection in the embodiment of the specification realizes the identification of the targets in the conference room and the detection of the targets identified as human bodies through the embodiment, and obtains the human body detection information. Optionally, in the embodiment of the present disclosure, each target in the conference room is detected in real time, and a real-time detection result is given.
In other optional embodiments, the obtaining, in step S104, person detection information in the conference room according to the radar detection information and the determined human body in the moving object, and performing conference person arrangement recommendation according to the person detection information further includes:
step S601, obtaining the total number of participants according to the determined human bodies in the moving object, and judging whether the total number of participants is larger than the recommended conference number.
In this step, since the human body in the conference room has been identified, the total number of human bodies, that is, the total number of participants in the conference room, can be obtained based on the identified human body. In this embodiment, the total number of participants calculated according to the real-time detection result of the target may be displayed on the conference machine display terminal in real time, so that the participants may learn the total number of the present participants at any time, and thus may learn how many participants should not be present, so as to facilitate subsequent arrangement.
Meanwhile, whether the conference room is suitable for the conference of the conference room or not can be judged according to the relation between the total number of the participants and the recommended number of the conference in real time, namely, whether the total number of the participants is larger than the recommended number of the conference is judged.
And step S602, if yes, recommending other idle meeting rooms to meeting participants in the meeting room.
If the total number of the participants is larger than the recommended conference number, other idle conference rooms can be recommended to the participants in the conference room, and conference room information of the idle conference rooms is displayed on the conference machine display terminal.
Optionally, if the total number of the participants is greater than the recommended number of the conference, whether other idle conference rooms with the recommended number of the conference greater than or equal to the total number of the participants exist can be further judged; if yes, recommending the idle meeting room to meeting participants in the meeting room; otherwise, reminding meeting participants in the meeting room to reasonably arrange seats.
In this embodiment, if the total number of participants is greater than the recommended number of conferences, that is, the conference room cannot sit down all the participants, the system may determine whether there is an idle conference room meeting the requirements according to the basic information of each conference room and the meeting situation stored in advance, if so, recommend a suitable idle conference room to the participants in the conference room, otherwise remind the participants in the conference room to reasonably arrange the seats.
Optionally, if the total number of participants is greater than the recommended number of the conference and there is no suitable conference room recommendation, a reminder may be sent to the conference room manager to remind the conference room manager to solve the problem, for example, by providing a temporary seat or the like to solve the problem that the participants cannot sit down.
In other optional embodiments, the obtaining, in step S104, person detection information in the conference room according to the radar detection information and the determined human body in the moving object, and making a conference person arrangement recommendation according to the person detection information may further include:
step S701, obtaining a target distance and a target angle according to the radar detection information.
The target distance and the target angle are information that can be directly detected by the millimeter wave radar, and thus the target distance and the target angle of the corresponding target can be obtained from the radar detection information.
Step S702, obtaining location information of the participants according to the determined human body in the moving target, the target distance and the target angle.
In the step, the participants are found out from the moving targets, and the specific positions of the participants can be confirmed by acquiring the target distances and the target angles corresponding to the human bodies.
And step 703, judging whether the participants are located outside the recommended viewing angle according to the location information of the participants and the location of the conference machine display terminal.
In this step, the recommended viewing angle of the conference display terminal may be obtained based on the placement position of the conference display terminal, and based on the specific positions of the participants obtained in step S702, it may be determined whether any participant is located at a position outside the recommended viewing angle.
If yes, step S704, recommending seats located within the recommended viewing angle to the participants located outside the recommended viewing angle; and/or controlling the conference machine display terminal to move so that all participants are located within the recommended viewing angle.
In this step, if the participant is located at a position outside the recommended viewing angle, it can be further determined whether the conference machine display terminal can be moved. If the conference machine display terminal can not move, recommending seats positioned in the recommended viewing angle by the participants positioned outside the recommended viewing angle; if the conference machine display terminal can move, the conference machine display terminal can be controlled to move a 1-a 2 meters forwards or backwards and b 1-b 2 meters leftwards or rightwards from the current position so that all participants are located within the recommended viewing angle. Meanwhile, the two modes can be combined for use, so that the watching experience of all participants is taken care of to the greatest extent.
In an alternative embodiment, as shown in fig. 4, step 104 may further specifically include:
step S801, counting personnel according to the human body judgment result to obtain the total number of the participants, and displaying the total number of the participants on the conference machine display terminal in real time.
In step S802, it is determined whether only a preset time range remains from the meeting start time, which is set to 10min in this embodiment. If yes, go to step S803; otherwise, the process returns to step S801.
Step S803, judging whether the total number of participants exceeds the recommended conference number of the conference room; if yes, go to step S805; otherwise, step S808 is performed.
Step S805, judging whether other suitable free meeting rooms exist; if yes, go to step S806; otherwise, step S807 is executed.
Step S806, recommending other free meeting rooms to the meeting participants in the meeting room. For example, "there is a suitable conference room, and replacement of the conference room to XXX" is recommended, which is displayed on the conference display terminal.
Step S807, reminding meeting participants in the meeting room to arrange seats reasonably. For example, "no suitable meeting room is temporarily left, and reasonable seating arrangement is recommended" is displayed on the meeting machine display terminal.
Step S808, if the total number of participants does not exceed the meeting recommended number of the meeting room, judging whether the positions of the seating personnel are reasonable. Namely, the position information of the participants is obtained according to the human body, the target distance and the target angle, and whether all the participants are located in the recommended viewing angle is judged based on the position information of the participants. If yes, go to step S809; otherwise, step S810 is performed.
Step S809, do not recommend, start meeting normally. For example, "ready" is displayed on the conference display terminal, and a conference can be started.
