It should be noted that the terms "first," "second," "target," and the like in the description and claims of the present invention and in the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
Fig. 1 is a flowchart of a gate traffic control method according to an embodiment of the present invention, where the method may be performed by a gate traffic control device, and the gate traffic control device may be implemented in hardware and/or software, and the gate traffic control device may be configured in an electronic device with data processing capability. As shown in fig. 1, the method includes:
s110, determining that a first object to be passed appears in front of the gate through an acquired image of the channel camera, and judging whether the width of the first object to be passed is larger than or equal to the channel width and smaller than the total width of the gate.
The passage camera can be a camera arranged at the position of a gate passage and can be used for collecting objects to be passed in a certain range in front of the gate. The gate comprises at least two parallel channels, and the channel body has a lifting function. Fig. 2 is a schematic diagram of a gate according to an embodiment of the invention. As shown in fig. 2, the gate includes two parallel channels, and a channel camera is installed at each channel. The object to be passed may refer to an object waiting to pass through the gate. For example, the object to be travelled may be a person and/or a large object (such as luggage, a bicycle, an electric vehicle or a wheelchair, etc.). The first object to be passed is relative to other objects to be passed, wherein the first object has no special meaning and only represents one object to be passed. For example, the first object to be passed may be a person carrying baggage.
In this embodiment, a first to-be-passed target is determined to appear in front of the gate through an acquired image of the channel camera, a width of the first to-be-passed target is identified, and then whether the width of the first to-be-passed target is greater than or equal to the channel width and less than the total width of the gate is determined. It can be understood that if the width of the first object to be passed is smaller than the width of the channel, the first object to be passed can be passed smoothly without adjusting the width of the gate channel; if the width of the first to-be-passed object is larger than the total width of the gate, the width of the first to-be-passed object is too wide, and even if the width of the gate channel is adjusted, the first to-be-passed object cannot be passed smoothly. Therefore, only if the width of the first to-be-passed object is greater than or equal to the channel width and less than the total gate width, it is necessary or necessary to adjust the gate channel width according to the width of the first to-be-passed object so that the first to-be-passed object can pass smoothly.
And S120, if the number of the traffic channels is satisfied, determining the number of the traffic channels according to the width of the first object to be passed and the width of the channels.
The number of traffic channels may refer to the number of channels that need to be occupied by traffic. In this embodiment, if the width of the first to-be-passed object is greater than or equal to the channel width and less than the gate total width, it indicates that the channel width needs to be adjusted. At this time, the number of the traffic lanes is determined according to the width of the first object to be traffic and the lane width. For example, assuming that the width of the first to-be-passed target is D and the width of one pass of the gate is D, the number of pass passes may be expressed as D/D. If D/D is not an integer, D/D is rounded upwards so that the width of the passing channel is larger than or equal to the width of the first object to be passed, and the first object to be passed can pass through the gate smoothly.
S130, determining a target passing channel of the first target to be passed according to the number of the passing channels and the distance between the first target to be passed and each channel, and issuing a body descending instruction to the target passing channel so that the first target to be passed passes through the gate.
The target traffic channel may refer to a channel that needs to be occupied by traffic. Specifically, the target passing channel may include a main channel and a matching channel, where the main channel may refer to a gate channel closest to the first target to be passed; the mating passage may refer to a passage other than the main passage in the target passage. The machine body descending instruction can be used for controlling the gate machine body of the target passing channel to descend to the level of the upper surface of the machine body and the ground.
In this embodiment, after the number of the traffic lanes is determined, the distance between the first to-be-passed target and each lane needs to be determined, so that the target traffic lane of the first to-be-passed target is determined according to the number of the traffic lanes and the distance between the first to-be-passed target and each lane. Specifically, the distance between the first object to be passed and each channel is first determined, and then the channel with the smallest distance is selected from the distances as the main channel. And then, taking the main channel as a reference, expanding the channels according to the number of the passing channels, and taking the channels obtained by expansion as matched channels. After the main channel and the mating channel are determined, the target traffic channel (main channel plus mating channel) can be determined. After the target passing channel is determined, a machine body descending instruction can be issued to the target passing channel so that the first target to be passed through the gate.
It should be noted that, in this embodiment, the channel expansion manner is not limited, and may be flexibly set according to actual application requirements. Illustratively, in performing the channel expansion, if only one of the two sides (left or right) of the main channel can be expanded, the channel expansion is performed toward the expandable side to obtain the fitting channel conforming to the number of the passing channels. If both sides of the main channel are expandable, the left expansion can be selected, and if the number of the left passage channels is insufficient, the remaining passage channels are expanded rightward; or the right expansion can be selected, if the number of the passing channels on the right side is insufficient, the number of the remaining passing channels is expanded leftwards, so that the matching channels which accord with the number of the passing channels are obtained.
According to the technical scheme, the first object to be passed is determined to appear in front of the gate through the acquired image of the channel camera, and whether the width of the first object to be passed is larger than or equal to the channel width and smaller than the total width of the gate is judged; if so, determining the number of the passing channels according to the width of the first object to be passed and the channel width; and determining a target passing channel of the first target to be passed according to the number of the passing channels and the distance between the first target to be passed and each channel, and issuing a body descending instruction to the target passing channel so that the first target to be passed passes through the gate. According to the technical scheme, the width of the gate passageway can be adaptively adjusted according to the width of the object to be passed, the problem that large objects pass inconveniently due to the fact that the gate passageway is narrow is effectively solved, the passing efficiency is improved, and the actual passing requirements are better met.
In this embodiment, optionally, in determining whether the width of the first to-be-passed target is greater than or equal to the channel width and less than the gate total width, the method further includes: if the width of the first object to be passed is smaller than the width of the channel, carrying out face recognition on the first object to be passed, and judging whether the same face recognition result exists in the acquired images of other channel cameras at the same moment; if the first to-be-passed object exists, determining the distance between the first to-be-passed object and each channel according to the acquired image of each channel camera; and determining an opening channel corresponding to the first object to be passed according to the distance.
In this embodiment, if the width of the first to-be-passed object is smaller than the width of the channel, it indicates that the first to-be-passed object is a person, and at this time, the gate channel does not need to be adjusted, i.e. the gate body does not need to be lowered. It should be noted that, under normal traffic, if the same person stands in the common identification area of the plurality of channel cameras, the person is identified by the plurality of channel cameras at the same time, and a person opens a plurality of gate channels at the same time. Therefore, it is necessary to further perform face recognition on the first object to be passed, and determine whether the same face recognition result exists in the acquired images of the other cameras at the same time.
For example, a similarity matching manner may be adopted to determine whether the same face recognition result exists in the collected images of the cameras of the channels at the same time. Specifically, firstly, face recognition results in collected images of cameras of all channels at the same moment are determined, and then similarity calculation between every two face recognition results is carried out. If the similarity is larger than the preset similarity threshold, the fact that the same face recognition result exists in the collected images of all the channel cameras at the same time is indicated, namely the same object to be passed is collected by at least two channel cameras at the same time. The preset similarity threshold may be a preset similarity reference value, which may be used as a basis for judging whether the face recognition result is the same. The preset similarity threshold is not limited in this embodiment, and may be set according to actual requirements, for example, the preset similarity threshold may be set to 98%.
If the same face recognition result exists in the acquired images of the other channel cameras at the same moment, the fact that the same object to be passed is acquired by at least two channel cameras at the same moment is indicated, namely the same object to be passed is repeatedly recognized by the channel cameras at the same moment, and at the moment, the distance between the first object to be passed and each channel needs to be determined according to the acquired images of the channel cameras. For example, the distance between the first object to be passed and each channel can be determined by calculating the distance from the first object to be passed in the acquired image to the central area of the acquired image. After determining the distance between the first to-be-passed object and each channel, the channel closest to the first to-be-passed object can be selected as the opening channel corresponding to the first to-be-passed object.
Through such setting, this scheme can effectively avoid alone to open the condition of multichannel to reduced personnel and missed the inspection phenomenon, improved current efficiency simultaneously.
In this embodiment, optionally, before issuing the body descent instruction to the target traffic channel, the method further includes: if the personnel verification result shows that the first to-be-passed target comprises a preset no-pass vehicle type or the face recognition of the first to-be-passed target is not passed, issuing of a body descending instruction to the target passing channel is prohibited; and if the personnel verification result shows that the first to-be-passed target does not comprise the preset no-pass vehicle type and the face recognition of the first to-be-passed target passes, issuing a body descending instruction to the target passing channel.
The preset traffic-prohibited vehicle type may refer to a predetermined vehicle type that prohibits the passage through the gate. For example, the preset traffic prohibition vehicle type may be a shared bicycle, and the gate is disposed at a cell entrance, and the shared bicycle is prohibited from entering the cell. It should be noted that, the personnel verification here may include two processes of vehicle type verification and face verification, if both the vehicle type verification and the face verification are successful, the personnel verification may be determined to be successful, otherwise, the personnel verification is determined to be failed.
In this embodiment, whether to issue the body descent instruction to the target passage may be determined according to the personnel verification result. For example, when the first to-be-passed target is a rider, the first to-be-passed target may be first subjected to vehicle identification to verify the vehicle type of the first to-be-passed target. If the vehicle type of the first to-be-passed target is a preset no-pass vehicle type, indicating that the vehicle type verification fails, directly determining that the personnel verification fails, namely that the first to-be-passed target does not have passing authority, and at the moment, prohibiting issuing an organism descending instruction to the target passing channel so as to prohibit the first to-be-passed target from passing through the gate; if the vehicle type of the first object to be passed is not the preset no-pass vehicle type, which indicates that the vehicle type verification is successful, the face recognition of the first object to be passed is needed. If the face recognition fails, the personnel verification failure can be determined, and the first object to be passed does not have the passing authority, and at the moment, the issuing of a body descending instruction to the object passing channel is also forbidden, so that the first object to be passed is forbidden to pass through the gate; if the face recognition is passed, the person verification can be determined to be successful, which indicates that the first object to be passed has the passing authority, and at the moment, a body descending instruction needs to be issued to the object passing channel so that the first object to be passed through the gate. The vehicle identification process and the face recognition process can be performed at any time after the first object to be passed appears before the gate is determined by collecting the images. For example, vehicle identification and face recognition may be performed on the first object to be passed before the number of the passage is determined.
Through such setting, the scheme can be according to first to-be-passed target motorcycle model verification result and face identification result, confirm personnel verification result fast, accurately, if personnel verification succeeds then send the organism decline instruction to the current passageway of target, if personnel verification fails then prohibit to send the organism decline instruction to the current passageway of target to effective control and management to the gate machine is passed.
Example two
Fig. 3 is a flowchart of a gate traffic control method according to a second embodiment of the present invention, which is optimized based on the above embodiment. The concrete optimization is as follows: before issuing the body descending instruction to the target passing channel, the method further comprises the following steps: judging whether the target passing channel is occupied by other targets to be passed in front of the gate; if so, determining the traffic priority according to the traffic time information of the first object to be passed and other objects to be passed.
As shown in fig. 3, the method of this embodiment specifically includes the following steps:
s210, determining that a first object to be passed appears in front of the gate through an acquired image of the channel camera, and judging whether the width of the first object to be passed is larger than or equal to the channel width and smaller than the total width of the gate.
S220, if the first object to be passed is met, determining the number of the passing channels according to the width of the first object to be passed and the channel width.
S230, determining a target passing channel of the first target to be passed according to the number of the passing channels and the distance between the first target to be passed and each channel.
The specific implementation of S210-S230 may be referred to in the detailed description of S110-S130, and will not be described herein.
S240, judging whether the target passing channel is occupied by other targets to be passed in front of the gate.
In this embodiment, after determining the target traffic channel of the first target to be traffic, it is necessary to further determine whether the target traffic channel is occupied by other targets to be traffic in front of the gate. If the passing channels of other objects to be passed in front of the gate are overlapped with the target passing channel of the first object to be passed, the situation that the target passing channel is occupied by the other objects to be passed in front of the gate can be indicated. The first to-be-passed object and the other to-be-passed objects need to occupy the number 2 and the number 3 channels for passing at the moment, that is, the channels to be occupied are overlapped, so that the object passing channel can be judged to be occupied by the other to-be-passed objects in front of the gate.
S250, if yes, determining the traffic priority according to the traffic time information of the first object to be passed and other objects to be passed.
The traffic time information may be used to characterize the time when the passage camera acquired the object to be passed. The traffic priority can be used as a basis for judging the traffic sequence of the objects to be passed. It is understood that the objects to be passed with high pass priority can pass preferentially, and the objects to be passed with low pass priority need to pass later.
In this embodiment, if the target traffic channel is occupied by other targets to be traffic before the gate, the traffic priority needs to be determined further according to the traffic time information of the first target to be traffic and the other targets to be traffic. By way of example, by comparing the traffic time information of the first object to be passed and the other objects to be passed, the traffic priority of the object to be passed in which the traffic time information is earlier may be determined as a high priority, and the traffic priority of the object to be passed in which the traffic time information is later may be determined as a low priority. That is, the channel camera collects which object to be passed first, and the passing time information of the object to be passed is indicated to be earlier (i.e. the time before reaching the gate is earlier), and the object to be passed can pass preferentially.
S260, issuing a machine body descending instruction to the target passing channel according to the passing priority, so that the first target to be passed or other targets to be passed pass through the gate.
In this embodiment, after determining the traffic priorities of the first to-be-passed object and the other to-be-passed objects, a body descending instruction may be issued to the object traffic channel corresponding to the to-be-passed object with a high traffic priority (the first to-be-passed object or the other to-be-passed object), so that the first to-be-passed object or the other to-be-passed object smoothly passes through the gate.
According to the technical scheme, before a body descending instruction is issued to the target passage, whether the target passage is occupied by other targets to be passed in front of a gate or not is judged; if so, determining the traffic priority according to the traffic time information of the first object to be passed and other objects to be passed. According to the technical scheme, the width of the gate passageway is adaptively adjusted according to the width of the to-be-passed target, the problem that large objects are inconvenient to pass due to the fact that the gate passageway is narrow is effectively solved, and on the basis of improving passing efficiency, when the condition that the target passing passageway is occupied by other to-be-passed targets before the gate is occurred, gate passing control can be carried out according to the passing priorities of the first to-be-passed target and the other to-be-passed targets, so that actual passing requirements can be better met.
In this embodiment, optionally, determining the traffic priority according to the traffic time information of the first to-be-passed object and the other to-be-passed objects includes: respectively determining initial acquisition time of a first object to be passed and other objects to be passed, which are identified by a channel camera; respectively determining the historical descending time of a target passage of a first target to be passed and other targets to be passed; wherein the historical descent time is the maximum value of the last descent times of all traffic lanes included in the target traffic lane; determining the time difference between the first object to be passed and other objects to be passed according to the initial acquisition time and the historical descent time of the first object to be passed and the other objects to be passed respectively; and determining the priority according to the time difference and the width of other objects to be passed.
The initial acquisition time may refer to an acquisition time when the object to be passed is first identified by the channel camera. The historical descent time may refer to the maximum value of the last descent times of all traffic lanes included in the target traffic lane. For example, assume that the target traffic lanes of the first target to be traffic are lanes 1, 2, and 3, and the last falling time corresponding to the three lanes is 3 points 50, 55, and 52, respectively. Therefore, the maximum value of the last falling time of the three traffic channels is 3 points 55 minutes corresponding to the No. 2 channel, and the historical falling time of the target traffic channel of the first target to be passed can be determined to be 3 points 55 minutes. The time difference may refer to the difference between the initial acquisition time and the historical fall time. For example, on the basis of the above example, assuming that the initial acquisition time corresponding to the first object to be passed is 4 points, the time difference may be expressed as a difference between 4 points and 3 points 55 minutes, that is, the time difference is 5 minutes.
In this embodiment, when determining the traffic priorities of the first to-be-passed object and the other to-be-passed objects, first, initial acquisition times of the first to-be-passed object and the other to-be-passed objects are determined respectively, and then historical descent times of the object traffic channels corresponding to the first to-be-passed object and the other to-be-passed objects are determined respectively. And then respectively determining the time difference between the first object to be passed and other objects to be passed according to the difference between the initial acquisition time and the historical descent time, and finally determining the priority according to the time difference between the first object to be passed and other objects to be passed and the width of the other objects to be passed.
In this embodiment, optionally, determining the priority according to the time difference and the width of other objects to be passed includes: if the width of the other objects to be passed is smaller than the width of the channel and the time difference of the first object to be passed is smaller than the preset time threshold, determining the priority of the other objects to be passed and the first object to be passed according to whether the object passing channel descends; if the width of the other objects to be passed is larger than or equal to the width of the channel and smaller than the total width of the gate, determining the priority according to the time difference between the first object to be passed and the other objects to be passed; or if the width of the other objects to be passed is smaller than the width of the channel and the time difference of the first object to be passed is larger than or equal to the preset time threshold, determining the priority according to the time difference of the first object to be passed and the other objects to be passed.
The preset time threshold may refer to a preset waiting time reference value. In this embodiment, if the width of the other objects to be passed is smaller than the width of the channel, it indicates that the other objects to be passed are personnel, and meanwhile, since the width of the first object to be passed is greater than or equal to the width of the channel and smaller than the total width of the gate, it indicates that the first object to be passed is greater than the width of the channel, i.e. the first object to be passed is a large object, at this time, the passing priorities of the personnel and the large object need to be determined according to the comparison result of the time difference of the first object to be passed and the preset time threshold. Specifically, if the width of the other objects to be passed is smaller than the width of the channel, if the time difference of the first object to be passed is smaller than the preset time threshold, whether the channel of the object to be passed is lowered is further determined, and the priorities of the other objects to be passed and the first object to be passed are determined according to the lowering condition of the channel of the object to be passed. If the target passing channel is lowered, determining that the priority of the first target to be passed is higher than that of other targets to be passed, namely, the priority of the large object is higher than that of personnel, and at the moment, the large object is in advance; if the target passing channel is not lowered, determining that the priority of other targets to be passed is higher than that of the first target to be passed, namely, the priority of personnel is higher than that of a large object, and then the personnel first. And under the condition that the width of the other objects to be passed is smaller than the width of the channel, if the time difference of the first object to be passed is larger than or equal to the preset time threshold, determining the priority according to the time difference of the first object to be passed and the other objects to be passed. If the width of the other objects to be passed is larger than or equal to the width of the channel and smaller than the total width of the gate, the other objects to be passed are large objects, and meanwhile, as the width of the first object to be passed is larger than or equal to the width of the channel and smaller than the total width of the gate, the first object to be passed is also large objects, and at the moment, the priority is determined according to the time difference between the first object to be passed and the other objects to be passed.
By the arrangement, when large objects and personnel have passing demands at the same time, the priority of the large objects and the personnel can be determined according to the comparison result of the time difference of the large objects and the preset time threshold; when a plurality of large objects have passing demands at the same time, the priority of each large object is determined according to the time difference of each large object, and the passing efficiency is further improved.
In this embodiment, optionally, determining the priority according to the time difference between the first to-be-passed object and the other to-be-passed objects includes: if the time difference between the first object to be passed and the other objects to be passed is the same, determining the pass priority according to the number of the object pass channels of the first object to be passed and the other objects to be passed; if the time difference between the first object to be passed and the other objects to be passed is different, determining the pass priority according to the comparison result of the time difference between the first object to be passed and the other objects to be passed.
In the embodiment of the invention, when the first object to be passed and the other objects to be passed are large objects, if the time difference between the first object to be passed and the other objects to be passed is the same, the objects to be passed with small number of the object passing channels are preferentially passed, i.e. the passing priority of the objects to be passed with small number of the object passing channels is high; if the time difference between the first object to be passed and other objects to be passed is different, the objects to be passed with large time difference are passed with priority, and the passing priority of the objects to be passed with large time difference is high.
By means of the arrangement, when the time difference between the first object to be passed and other objects to be passed is the same, the pass priority is determined according to the number of the object pass channels; when the time difference between the first object to be passed and other objects to be passed is different, the pass priority is determined according to the time difference, and the pass efficiency and the pass waiting time can be simultaneously considered.
In this embodiment, optionally, after determining the priority according to the magnitude of the time difference between the first to-be-passed object and the other to-be-passed objects, the method further includes: after the final to-be-passed object with high priority is determined to pass, when the priorities of the remaining to-be-passed object and the new to-be-passed object are determined, the historical descending time of the remaining to-be-passed object is determined according to the record before the final to-be-passed object passes, and the historical descending time of the new to-be-passed object is determined according to the record after the final to-be-passed object passes; the remaining objects to be passed are objects with priority compared with the final objects to be passed; the new to-be-passed target is a target which is not compared with the final to-be-passed target in priority.
The final to-be-passed target may refer to a to-be-passed target with a high priority. The remaining objects to be passed may refer to objects that are compared in priority with the final objects to be passed. The new to-be-passed target may refer to a target that is not compared in priority with the final to-be-passed target.
In this embodiment, after determining the priority according to the time difference between the first to-be-passed object and the other to-be-passed objects, the to-be-passed object with the high priority may be determined as the final to-be-passed object. After the final object to be passed finishes passing, the historical descending time of the object passing channel of the final object to be passed is correspondingly updated. After the final to-be-passed object completes the pass, the pass priority of the remaining to-be-passed object and the new to-be-passed object needs to be determined further according to the time difference (the difference between the initial acquisition time and the historical descent time) between the remaining to-be-passed object and the new to-be-passed object. The historical descending time of the remaining objects to be passed is determined according to the record before the final objects to be passed pass, namely the historical descending time of the remaining objects to be passed is kept unchanged; and determining the historical descending time of the new object to be passed according to the record of the final object to be passed after passing.
Through the arrangement, the priority of the remaining objects to be passed and the new objects to be passed can be determined according to the historical descending time determined under different conditions, and the passing efficiency is further improved.
