Description

Technical Field

[0001] The present invention relates to the field of channel control, and in particular to a gate passage control method, device, equipment and storage medium. Background Art

[0002] A turnstile is a channel blocking device (channel management equipment) used to manage the flow of people and regulate the entry and exit of pedestrians. Its most basic and core function is to allow only one person to pass through at a time. Turnstiles can be used at the entrances and exits of various occasions, such as office buildings, train stations, subways or other public places. However, when the number of people entering and exiting reaches a peak, it is difficult to ensure the efficiency of the turnstile channel that only allows one person to pass through at a time, which usually causes traffic congestion.

[0003] In the related art, in order to improve the efficiency of gate passage, the number of gate opening and closing is generally reduced when multiple people pass through. For example, when multiple people pass through in a short period of time, after the gate is opened for the first time, the gate is controlled to remain open until the last person passes through the gate. However, this method is prone to problems such as the gate suddenly closing or being squeezed by the gate due to misjudgment during passage, which not only fails to ensure passage efficiency, but also easily causes inconvenience to passers-by.

[0004] Therefore, the problem of low gate efficiency needs to be solved urgently. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a gate passage control method, device, equipment and storage medium to solve the problems of low gate passage efficiency and low safety.

[0006] To solve the above technical problems, the embodiments of the present application are implemented as follows:

[0007] On the one hand, an embodiment of the present application provides a gate passage control method, including:

[0008] Detecting the traffic status information of the first area; the first area is the passage between the boundaries of the gate body in the length direction of the gate;

[0009] If the passage status information indicates that there is no object passing through the first area and the gate is in an open state, it is determined whether there is a target object within the first channel range; the first channel range includes the range between the gate and a preset position; the preset position is a position that does not reach the gate body in the passage direction and is located between the boundaries of both sides of the gate body;

[0010] If the target object exists within the range of the first channel, the gate is controlled to maintain the open state.

[0011] On the other hand, an embodiment of the present application provides a gate passage control device, comprising:

[0012] A first detection module is used to detect the traffic status information of a first area; the first area is the passage between the boundaries on both sides of the gate body in the length direction of the gate;

[0013] A first judgment module is used to judge whether there is a target object within a first channel range if the passage status information indicates that there is no passing object in the first area and the gate is in an open state; the first channel range includes a range between the gate and a preset position; the preset position is a position that does not reach the gate body in the passage direction and is located between the boundaries of both sides of the gate body;

[0014] The first control module is used to control the gate to maintain the open state if the target object exists within the range of the first channel.

[0015] On the other hand, an embodiment of the present application provides a gate access control device, including a processor and a memory electrically connected to the processor, the memory storing a computer program, and the processor being used to call and execute the computer program from the memory to implement the above-mentioned gate access control method.

[0016] On the other hand, an embodiment of the present application provides a storage medium for storing a computer program, wherein the computer program can be executed by a processor to implement the above-mentioned gate passage control method.

[0017] The technical solution of the embodiment of the present application is adopted to detect the traffic status information of the first area, wherein the first area is the passage between the boundaries of the gate body and the length direction of the gate. If the traffic status information indicates that there is no passing object in the first area and the gate is in an open state, it is determined whether there is a target object within the range of the first channel, wherein the range of the first channel includes the range between the gate and a preset position; the preset position is a position that does not reach the gate body in the direction of passage and is located between the boundaries of the gate body. If there is a target object within the range of the first channel, the gate is controlled to remain in an open state, thereby avoiding frequent opening or closing of the gate, which not only avoids wasting the passage time of the target object, effectively improves the passage efficiency of the first area, but also avoids the frequent opening or closing of the gate causing inconvenience to the passage of the target object.

[0025] The purpose of the embodiments of the present application is to provide a gate passage control method, device, equipment and storage medium to solve the problems of low gate passage efficiency and lack of convenience.

[0026] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0027] The present application provides a gate passage control method which can be applied to Figure 1 The control system of gate passage shown in the figure. Figure 1As shown, the control system for gate passage includes a right gate machine, a left gate machine, an entry camera and an exit camera. Among them, the right gate machine includes a door wing 1 and a built-in main controller chip and a channel control chip 1, and the left gate machine includes a door wing 2 and a built-in channel control chip 2. The main controller chip is used to detect the traffic status information in the first area, and send relevant instructions to at least one of the channel control chip 1 and the channel control chip 2 according to the traffic status information to control the opening or closing of the door wing. Exemplarily, after the channel control chip 1 receives the relevant instructions of the main controller chip, it can control the opening or closing of the door wing 1 based on the instructions; after the channel control chip 2 receives the relevant instructions of the main controller chip, it can control the opening or closing of the door wing 2 based on the instructions. The motor control algorithm can be integrated in the channel control chip 1 and the channel control chip 2, and the opening or closing of the door wing is controlled by the algorithm. Since the motor control algorithm belongs to the prior art, it will not be described in detail here.

[0028] In addition, only one channel control chip may be set, and the channel control chip can be set in the right machine or the left machine of the gate, and the channel control chip can be used to control the opening or closing of door wing 1 and / or door wing 2. The embodiment of the present application does not limit this.

[0029] The inbound camera can be installed on the right side of the gate, or between the left side and the right side of the gate, and close to the right side of the gate. The inbound camera is used to detect the passing status information of the objects passing within the corresponding detection range in the inbound direction. The outbound camera can be installed on the left side of the gate, or between the left side and the right side of the gate, and close to the left side of the gate. The outbound camera is used to detect the passing status information of the objects passing within the corresponding detection range in the outbound direction.

[0030] In this embodiment, the installation positions of the input camera and the output camera are only examples. In actual applications, the installation positions of the cameras can be determined based on the detection requirements for passing objects in different directions (such as detection distance, detection accuracy, etc.).

[0031] In the gate passage control method provided in one or more embodiments of this specification, the "first area" refers to the passage between the two sides of the gate body in the length direction of the gate. The gate body is the left gate and the right gate mentioned above. In any of the embodiments described below, the meaning of the first area is the same, so it will not be repeated.

[0032] Figure 2 is a schematic flow chart of a gate passage control method according to an embodiment of the present invention, such as Figure 2 As shown, this method is applied to Figure 1 The gate passage control system shown includes the following steps S202-S206:

[0033] S202, detecting the traffic status information of the first area; wherein the first area is the passage between the boundaries on both sides of the gate body in the length direction of the gate.

[0034] In this embodiment, the first area generally includes two directions, exit and entry, and corresponding detection devices can be installed in each direction. For example, the "exit" direction of the first area is installed with a detection device for detecting the traffic status information in the exit direction, and the "entrance" direction of the first area is installed with a detection device for detecting the traffic status information in the entry direction.

[0035] The traffic status information includes whether there is a passing object in the first area. Optionally, a detection device such as a visible light camera device, an infrared camera device, etc. is used to detect whether there is a passing object in the first area.

[0036] S204: If the traffic status information indicates that there is no object passing through the first area and the gate is in an open state, determine whether there is a target object within the range of the first channel.

[0037] Among them, the first channel range includes the range between the gate and the preset position, and the preset position is a position that does not reach the gate body in the direction of passage and is located between the boundaries on both sides of the gate body.

[0038] Among them, the traffic status information is that there is no passing object in the first area and the gate is in an open state. This state may occur in many situations. Two common situations are listed below:

[0039] In the first case, the last passing object has just passed through the first area, but the gate is still in an open state (ie, before the gate is controlled to be closed). At this time, it is detected that there is no passing object in the first area and the gate is in an open state.

[0040] In the second case, the gate is kept open (such as controlling the gate to be always open during peak traffic hours). At this time, if there is no passing object in the first area, it will be detected that there is no passing object in the first area and the gate is in the open state.

[0041] In this embodiment, the first channel range is the range for detecting and identifying the target object through the detection device in the gate. When the detection device is a camera device, the first channel range can be the field of view angle range of the camera device, or smaller than the field of view angle range of the camera device. The setting of the first channel range should ensure that the camera device can identify but will not identify across channels. Figure 3 As an example, Figure 3 It is a schematic diagram of the first channel range of a double gate channel (i.e., two first areas formed by three adjacent gates) of an embodiment of the present application.

[0042] like Figure 3 As shown, the double gate channel includes gate channel A (i.e., the first area, gate channel A will be used to replace the first area below) and gate channel B (i.e., the first area, gate channel B will be used to replace the first area below), and the camera device includes camera device A and camera device B, wherein camera device A is used to detect the target object "entering" the gate channel A (i.e., the direction indicated by the arrow in gate channel A), and camera device B is used to detect the target object "entering" the gate channel B (i.e., the direction indicated by the arrow in gate channel B). The first channel range corresponding to camera device A is: a trapezoidal range with the extension line of the lens diameter of camera device A as the upper base, P1P2 at a preset distance d from camera device A as the lower base, and the preset distance d as the height (such as Figure 3 The first channel range may be the field of view angle range of the camera device A, or may be smaller than the field of view angle range of the camera device A. The first channel range corresponding to the camera device B is a trapezoidal range (such as Figure 3 The first channel range may be the field of view range of the camera device B, or may be smaller than the field of view range of the camera device B. Optionally, the preset distance d may be 2.5 meters. Figure 3 It can be seen that the first channel range and the first area have a part of overlap, but the two are not the same. In addition to the range that overlaps with the first area, the first channel range may also include a range outside the first area and within the field of view of the camera device. In addition, the first channel range corresponding to the camera A and the first channel range corresponding to the camera B do not overlap with each other, so as to avoid the situation where different cameras recognize the same target object and cause the gate control disorder.

[0043] S206: If there is a target object within the range of the first channel, the gate is controlled to remain open.

[0044] The technical solution of the embodiment of the present application is adopted to detect the traffic status information of the first area, wherein the first area is the passage between the boundaries of the gate body and the length direction of the gate. If the traffic status information shows that there is no passing object in the first area and the gate is in an open state, it is determined whether there is a target object within the range of the first channel, wherein the range of the first channel includes the range between the gate and a preset position; the preset position is a position that does not reach the gate body in the direction of passage and is located between the boundaries of the gate body. If there is a target object within the range of the first channel, the gate is controlled to remain in an open state, thereby avoiding frequent opening or closing of the gate, which can not only avoid wasting the passage time of the target object, effectively improve the passage efficiency in the first area, but also avoid the frequent opening or closing of the gate causing inconvenience to the passage of the target object.

[0045] In one embodiment, considering that there are fewer objects entering and leaving the first area during certain time periods, it is not necessary to control the gate to remain open, but only to control the gate to open and close in the form of only one person passing through at a time. However, during certain time periods, the flow of objects entering and leaving the first area is large, and the method of only one person passing through the first area at a time will greatly reduce the traffic efficiency. Therefore, before detecting the traffic status information in the first area, it can be determined when to execute S202 to S206. Among them, the method for determining the execution timing of S202 to S206 may include at least one of the following methods:

[0046] Method 1: determining whether the current time belongs to a preset time period; wherein, within the preset time period, the number of target objects within the first channel range is greater than or equal to a first preset threshold.

[0047] In the first method, the preset time period can be determined according to the application scenario and traffic conditions of the first area. For example, the application scenario may include office building entrances and exits, railway station entrances and exits, library entrances and exits, student dormitory entrances and exits, etc. The traffic conditions may include the traffic time and the number of traffic of the target object. For example, when the application scenario is the entrance and exit of an office building, it is assumed that the traffic volume is high during the time periods of 8:00 to 10:00 in the morning, 12:00 to 13:00 in the afternoon, and 5:00-7:00 in the afternoon, which is the peak traffic period of the first area. Therefore, the above time periods can be set as preset time periods, and steps S202 to S206 can be performed during the preset time periods.

[0048] In addition, the preset time periods listed above can be counted by a user or a computer. If counted by a computer, the number of target objects within the first channel range in different time periods of each day can be counted first, and then the number of target objects in each time period can be compared with the first preset threshold value respectively. According to the comparison result, the time period in which the number of target objects is greater than or equal to the first preset threshold value is determined as the preset time period. When performing statistics, the application scenario is still taken as an example of the entrance and exit of an office building, and the traffic conditions of the entrance and exit of the office building during each working day and each rest day are similar. Therefore, five working days can be used as a statistical cycle, and two rest days can be used as another statistical cycle, that is, the number of target objects in each time period of five working days is counted, and then the average number of target objects in the corresponding time period of each working day is calculated. If the average number is greater than or equal to the first preset threshold value, the time period is used as the preset time period of the working day; and the number of target objects in each time period of two rest days is counted, and then the average number of target objects in the corresponding time period of each rest day is calculated. If the average number is greater than or equal to the first preset threshold value, the time period is used as the preset time period of the rest day.

[0049] For another example, when the application scenario is the entrance and exit of a student dormitory, the traffic conditions in the time periods corresponding to before and after class time are usually more complicated, which can be used as the peak traffic period of the first area. Since the application scenario is the entrance and exit of a student dormitory, the traffic conditions during weekdays and holidays are not completely similar. During weekdays, the traffic conditions corresponding to the time periods before and after class time may be more complicated, so the time periods before and after class time when the number of target objects is greater than or equal to the first preset threshold can be set as the preset time period; and during holidays, the traffic conditions corresponding to the time period corresponding to the dining time may be more complicated, so the dining time period when the number of target objects is greater than or equal to the first preset threshold can be set as the preset time period, and then steps S202 to S206 are performed within the above preset time period.

[0050] In addition, historical traffic information in the first area at a preset time may also be obtained. If the preset time includes multiple time periods, the historical traffic information may include the historical traffic counts of the target object in the first area corresponding to each time period. According to the historical traffic counts, a time period in which the average historical traffic count exceeds a first preset threshold is determined as the preset time period. For example, the preset time may be the last five days, ten days, thirty days, and so on.

[0051] Optionally, each day is divided into several time periods on average, and the historical number of passes in the first area corresponding to each time period in the past five days is obtained. Then, based on the historical number of passes, the time period in which the average historical number of passes exceeds a first preset threshold is determined as the preset time period.

[0052] Method 2: Detecting the number of target objects within the first channel range: If the number of target objects is greater than or equal to the second preset threshold, start detecting the traffic status information within the first area, that is, execute the above steps S202 to S206.

[0053] Taking the first area set at the entrance and exit of a railway station as an example, due to the complex traffic conditions at the railway station, the number of target objects corresponding to the first area set at the entrance and exit of the railway station in each time period also changes irregularly. Therefore, the number of target objects within the range of the first channel can be detected in real time to determine how to control the gate.

[0054] In a specific implementation, a detection device, such as a visible light camera device, can be used to capture a visible light image within the first channel, and then the main controller chip in the gate can be used to identify the facial information of the target object in the visible light image, and then determine whether the number of faces of the target object is greater than or equal to a second preset threshold. If so, steps S202 to S206 can be executed.

[0055] In this embodiment, before detecting the traffic information of the first area, a preset time period for executing steps S202 to S206 is pre-set in a targeted manner; or the number of target objects is detected in real time, and then steps S202 to S206 are executed when the number of target objects is greater than or equal to a second preset threshold value. This allows the control method for the passage of the gate to be implemented in a targeted manner according to different time periods. In this way, unnecessary resource consumption is reduced while improving the passage efficiency of the gate.

[0056] In one embodiment, if the traffic status information indicates that there is a passing object in the first area and the gate is in an open state, the target object is verified for access rights. If the target object's access rights are verified, it is determined whether the target object has passed the first area within a third preset time period, wherein the third preset time period is the time period for which the gate remains open after the target object's access rights are verified; if the target object has not passed the first area within the third preset time period, the gate is controlled to close, thereby increasing the verification of the target object and ensuring the safety of gate access control.

[0057] In one embodiment, if there is a passing object in the first area (i.e. after executing the above S202), the following steps B1 to B3 may be executed:

[0058] Step B1: If there is a passable object in the first area, the pass authority of the passable object is verified.

[0059] In this step, the process of verifying the access authority of the access object will be described in detail in the following embodiments.

[0060] Step B2: If the access authority of the access object is verified, it is determined whether the access object passes through the first area within a first preset time period.

[0061] Among them, the first preset time length is the time length that the gate remains open after the access permission verification of the access object is passed, such as 5 seconds.

[0062] Step B3, if the passing object passes through the first area within the first preset time, the gate is controlled to be opened; if the passing object does not pass through the first area within the first preset time, the gate is controlled to be closed.

[0063] In this embodiment, there are multiple situations in which there are passing objects in the first area, and two situations are exemplarily listed below:

[0064] Case 1: After detecting the traffic status information of the first area, it is detected that the traffic status information indicates that there is a passing object in the first area.

[0065] Among them, the state of the passage status information indicating that there is a passing object in the first area may include multiple situations, and two common situations are listed below: 1. After the previous passing object's access authority verification is passed, but the gate is still in the open state (i.e., before the gate is controlled to be closed), at this time, the passing object is detected in the first area. 2. After the previous passing object has passed the first area, the gate is in the closed state, and the passing object is detected in the first area.

[0066] Case 2: After detecting that the traffic status information indicates that there is no object in the first area and the gate is in an open state, it is determined that there is a target object in the first channel range. The target object in the first channel range is continuously monitored, and when it is detected that the target object in the first channel range enters the first area from the first channel range, it is determined that there is a object in the first area.

[0067] It can be seen that when there are passing objects in the first area, the passing objects are firstly verified for their access rights to ensure that the passing objects in the first area can pass through the first area smoothly, thereby ensuring the safety of the gate passage; further, after determining that there are no passing objects in the first area, it is detected that there is a target object within the range of the first channel, and the gate is controlled accordingly (such as controlling to open or close) according to the detection result, so as to improve the response rate of the first area, thereby improving the passage efficiency. In one embodiment, in order to ensure the accuracy of the detection of the target object, the access rights of the target object can be verified when the target object enters and exits the first area. For example, the mobility of objects entering and exiting public places such as office buildings, student dormitories and other buildings is relatively strong. In order to facilitate the security control of objects entering and exiting the building, the access rights of the above-mentioned objects entering and exiting are verified when they pass through the first area.

[0068] If there is a target object in the first area, the gate is controlled to remain open. Further, the target object is authenticated for access. The authentication process can be implemented by performing the following steps A1 to A3:

[0069] Step A1, obtaining the face information of the target object.

[0070] A visible light image in the first area is captured by a detection device in the gate, such as a visible light camera device or an infrared camera device, and then the facial information of the target object in the visible light image is recognized by a main controller chip in the gate.

[0071] Step A2: If the face information is acquired within the second preset time period, the face information is recognized using face recognition technology to obtain a recognition result. According to the recognition result, it is determined whether the access authorization verification of the target object is passed.

[0072] The second preset time is a preset time for verifying the access authority. Any existing face recognition technology can be used to recognize the face information. The face information recognition process may include image preprocessing, face feature extraction, and face feature recognition, so as to obtain the face information recognition result.

[0073] When performing face recognition, the face information of the target object obtained in real time can be matched with the standard face information corresponding to the target object. Before performing face recognition, the standard face information of the target object can be collected in advance, and the collected standard face information can be stored in a designated database, so that when the face information of the target object is recognized, the corresponding standard face information can be obtained from the designated database; or, when performing face recognition, the standard face information of the target object stored on the network side can be obtained in real time according to the identification information (such as name, telephone number, etc.) of the target object.

[0074] The recognition result may include that the facial information matches the standard facial information corresponding to the target object, or that the facial information does not match the standard facial information.

[0075] Optionally, if the recognition result is that the facial information matches the standard facial information corresponding to the target object, it is determined that the access permission verification has passed; if the recognition result is that the facial information does not match the standard facial information, it is determined that the access permission verification has not passed.

[0076] Optionally, considering that in some scenarios, gate access authority is not only related to the passer but also to the time period, that is, the passer may not have access authority in all time periods. Based on this, when judging whether the target object's access authority verification has passed, in addition to using the recognition result of the face information as a basis, other factors can also be combined for comprehensive judgment, such as whether the target object has access authority at the current time.

[0077] In one implementation, if the face information recognition result is that the face information matches the standard face information corresponding to the target object, it is further verified whether the current time is within the passable time of the target object. If the current time is within the passable time of the target object, it is determined that the pass permission verification has passed; if the current time is not within the passable time of the target object, it is determined that the pass permission verification has failed.

[0078] For example, the passable time of target object X is from 8:00 am to 10:00 pm every day, that is, target object X has the right of passage only during this time period. If the current time is 1:00 pm, after determining that the real-time acquired face information matches the standard face information of target object X, it is determined that the current time belongs to the passable time of target object X, and it is determined that the passability verification of target object X has passed. For another example, if the current time is 7:00 am, after determining that the real-time acquired face information matches the standard face information of target object X, it is determined that the current time does not belong to the passable time of target object X, and it is determined that the passability verification of target object X has not passed.

[0079] Step A3: If the facial information of the target object is not obtained within the second preset time period, it is determined that the access authority verification of the target object has failed.

[0080] In this embodiment, if the facial information of the target object is not obtained within the second preset time period, there may be the following reasons: 1. The camera device in the gate cannot capture the face of the target object during the target object's access authorization verification (such as the face of the target object is not facing the camera device, etc.), resulting in the inability to obtain facial information; 2. The standard facial information of the target object pre-stored in the specified database cannot be obtained, and the standard facial information of the target object on the network side cannot be obtained, resulting in the inability to match the facial information of the target object and the standard facial information of the target object within the second preset time period. Among them, the standard facial information of the target object has been described in the previous embodiment and will not be repeated here.

[0081] It can be seen that this embodiment matches the facial information of the identified target object with the pre-stored standard facial information to verify whether the target object has access rights, thereby ensuring the security of the gate access control; and by setting the second preset time length to give the main controller chip a reaction time for face recognition, it is only when the facial information of the target object cannot be obtained within the second preset time length that the target object is considered to have failed the access right verification, thereby effectively preventing the problem of the gate being closed due to the inability to collect the facial information of the target object in time when the target object enters the first channel, and effectively improving the access rate of the gate channel. In addition, in the scenario where the target object's passable time is restricted, by verifying whether the current time belongs to the target object's passable time, the verification result of the access right is made more accurate, thereby strengthening the strictness of the gate access control and achieving the best security effect.

[0082] In one embodiment, considering that in an actual scenario, the same target object may exist in the first channel range corresponding to two adjacent first areas, or the camera devices corresponding to two adjacent first areas simultaneously detect the same target object, in order to ensure the accuracy of gate control, when controlling the gate to remain open, the following method can be used to control: if the same target object exists in the first channel range corresponding to two adjacent first areas, the position information of the target object is detected. Then, the position information of the target object is analyzed, and the target channel range corresponding to the target object is determined based on the analysis result. Then, the gate corresponding to the target channel range is controlled to remain open. Among them, the target channel range is one of the multiple first channel ranges.

[0083] by Figure 3 Taking the scene shown as an example, the camera devices of the two adjacent first areas are camera device A and camera device B, respectively, and both camera device A and camera device B are visible light camera devices. The position information of the target object can be detected according to the visible light camera device, wherein the visible light lens in the visible light camera device can adopt a monocular lens, which has an image shooting function and a monocular vision positioning and ranging function; the position information of the target object can be the coordinate information of the target object relative to the visible light camera device. In addition, each position within the first channel range corresponding to gate channel A has corresponding coordinate information relative to camera device A, and each position within the first channel range corresponding to gate channel B has corresponding coordinate information relative to camera device B, then the coordinate range of the first channel range corresponding to gate channel A relative to camera device A, and the coordinate range of the first channel range corresponding to gate channel B relative to camera device B can be determined.

[0084] First, a visible light image is captured by a visible light camera device corresponding to the first area, and the visible light image includes a target object. Then, the captured visible light image is positioned using a monocular lens in the visible light camera device to obtain coordinate information of the target object in the visible light image relative to the visible light camera device. Then, the coordinate information of the target object is compared to see whether it is within the coordinate range of the first channel range corresponding to the visible light camera device. If so, it is determined that the target object is within the first channel range corresponding to the visible light camera device.

[0085] For example, if the same target object exists in the first channel ranges corresponding to two adjacent first areas, the two first areas ( Figure 3 The camera devices corresponding to the A gate channel and the B gate channel will respectively detect the coordinate information of the target object relative to their respective camera devices: the A camera device detects the first coordinate information of the target object relative to the A camera device, and the B camera device detects the second coordinate information of the target object relative to the B camera device. If the first coordinate information of the target object relative to the A camera device is within the coordinate range corresponding to the A gate channel, and the second coordinate information of the target object relative to the B camera device is not within the coordinate range corresponding to the B gate channel, then the target channel range corresponding to the target object is determined to be the first channel range corresponding to the A gate channel, and the gate corresponding to the A gate channel can be controlled to remain open.

[0086] In this embodiment, considering that the same target object exists in the first channel ranges corresponding to two adjacent first areas, the target channel range corresponding to the target object is first determined, and then the gate corresponding to the target channel range is controlled to remain open, thereby preventing the gate from being closed incorrectly, which can improve the accuracy of controlling the opening or closing of the gate and thereby improve the passage efficiency of the gate.

[0087] Figure 4 FIG. 1 is a schematic flow chart of a gate passage control method according to another embodiment of the present application. Figure 4 As shown, the method includes the following S401 to S410:

[0088] S401, determining whether the current time belongs to a preset time period, or detecting the number of target objects within a first channel range, and the number of target objects is greater than or equal to a second preset threshold.

[0089] Wherein, within the preset time period, the number of target objects within the first channel range is greater than or equal to the first preset threshold. The first preset threshold and the second preset threshold may be equal or unequal, and this embodiment does not limit them.

[0090] S402: Detect traffic status information in the first area.

[0091] The first area is the passage between the two sides of the gate body in the length direction of the gate. The traffic status information includes whether there is a passing object in the first area.

[0092] After S402, different steps may be performed according to different traffic status information. In this embodiment, if the traffic status information indicates that there is a traffic object in the first area, S403 is performed; if the traffic status information indicates that there is no traffic object in the first area, S405 is performed.

[0093] S403, verifying the access authority of the access object.

[0094] S404: If the pass permission verification of the pass object is passed, it is determined whether the pass object passes through the first area within the first preset time period. If yes, S406 is executed; if no, S410 is executed.

[0095] Among them, the first preset time length is the time length that the gate remains open after the access permission verification of the access object is passed.

[0096] S405, determine whether there is a target object within the range of the first channel. If yes, execute S406; if no, execute S410.

[0097] Among them, the first channel range includes the range between the gate and the preset position, and the preset position is a position that does not reach the gate body in the direction of passage and is located between the boundaries on both sides of the gate body.

[0098] S406, control the gate to open.

[0099] S407, acquiring facial information of the target object within a second preset time period, and identifying the facial information using facial recognition technology to obtain a recognition result.

[0100] The second preset time duration is a preset time for verifying access rights. The recognition result includes that the facial information matches the standard facial information corresponding to the target object, or that the facial information does not match the standard facial information. The standard facial information is the standard facial information corresponding to the target object obtained from a specified database, or the standard facial information of the target object stored on the network side.

[0101] In addition, if the facial information of the target object is not obtained within the second preset time period, it can be directly determined that the access authority verification of the target object has failed.

[0102] S408, judging whether the access authorization verification of the target object is passed according to the recognition result. If yes, execute S409; if no, execute S410.

[0103] Among them, if the recognition result is that the facial information matches the standard facial information corresponding to the target object, it is determined that the access permission verification has passed; if the recognition result is that the facial information does not match the standard facial information, it is determined that the access permission verification has not passed.

[0104] S409, determining whether the target object passes through the first area within a third preset time period; if not, executing S410.

[0105] Among them, the third preset time length is the time length that the gate remains open after the target object's access permission verification is passed.

[0106] S410, control the gate to close.

[0107] By adopting the technical solution of this embodiment, by setting a preset time period in a targeted manner before detecting the passage information of the first area, or detecting the number of target objects in real time, and then executing the corresponding steps when the number of target objects is greater than or equal to the second preset threshold, the control method of the gate passage can be implemented in a targeted manner according to different time periods, thereby reducing unnecessary resource consumption while improving the gate passage efficiency. In addition, by verifying the access rights of the target objects within the first channel range, the security of the gate passage control is ensured; further, after the access rights of the target objects are verified, if the target objects do not pass through the first area within the third preset time period, the gate is controlled to be closed, which not only improves the verification strength of the target objects, but also improves the effect of the gate passage control.
