Description

Technical Field

[0001] This invention relates to the field of security inspection technology, and in particular to a method, device, equipment and storage medium for adjusting the speed of a security inspection machine. Background Technology

[0002] As public awareness of security at key locations increases, security screening equipment is being used more and more widely. For example, security screening equipment is installed in long-distance bus stations, subway stations, train stations, and airports. People need to place their carry-on luggage on the conveyor belt of the security screening equipment to scan for dangerous items.

[0003] In the application scenarios of security inspection equipment, the flow of people varies at different times. If the conveyor belt of the security inspection equipment is kept running at a constant speed, resources will be wasted when there are no bags or packages to be inspected. However, when a large number of people rush in in a short period of time and the number of bags and packages to be inspected suddenly increases, security inspection efficiency will be insufficient and crowding will occur.

[0004] To address these issues, existing technologies often employ either manually adjusting the operating speed of security screening equipment based on the volume of luggage or packages, or automatically adjusting the speed based on the volume of luggage or packages over a given period. Manual adjustment is highly dependent on staff and consumes significant manpower, while automatic adjustment based on the volume of luggage or packages over a period can only be made after a certain time has passed, resulting in a certain lag and still failing to prevent overcrowding. Summary of the Invention

[0005] This invention provides a method, device, equipment, and storage medium for adjusting the speed of a security inspection machine, in order to solve the problem of lag in the speed control of the security inspection machine.

[0006] According to one aspect of the present invention, a method for adjusting the speed of a security inspection machine is provided, comprising:

[0007] The current flow of people at the entrance of the security screening machine is determined by recognizing images of people at the entrance.

[0008] The operating speed of the conveyor belt in the security inspection machine is adjusted according to the current flow of people.

[0009] According to another aspect of the present invention, a speed adjustment device for a security inspection machine is provided, comprising:

[0010] The people flow determination module is used to determine the current people flow at the entrance of the security checkpoint by recognizing images of people at the entrance.

[0011] The speed adjustment module is used to adjust the running speed of the conveyor belt in the security inspection machine according to the current flow of people.

[0012] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0013] At least one processor; and

[0014] A memory communicatively connected to the at least one processor; wherein,

[0015] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the security inspection machine speed adjustment method according to any embodiment of the present invention.

[0016] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the security inspection machine speed adjustment method according to any embodiment of the present invention.

[0017] The technical solution of this invention identifies the images of people at the entrance of the security inspection machine to determine the current flow of people at the entrance. Then, based on the current flow of people, the running speed of the conveyor belt in the security inspection machine is adjusted. This allows for advance adjustment of the conveyor belt speed according to the flow of people, solving the problem of lag in conveyor belt adjustment, saving energy, and improving security inspection efficiency.

[0030] Example 1

[0031] Figure 1a This invention provides a flowchart of a method for adjusting the speed of a security screening machine according to Embodiment 1. This embodiment is applicable to situations where the speed of a security screening machine is adjusted based on the flow of people. The method can be executed by a security screening machine speed adjustment device, which can be implemented in hardware and / or software and can be configured in various general-purpose computing devices. Figure 1a As shown, the method includes:

[0032] S110. By recognizing the images of people at the entrance of the security checkpoint, the current flow of people at the entrance of the security checkpoint is determined.

[0033] The personnel image is an image captured at the entrance of the security checkpoint, containing images of people undergoing security checks. For example, the personnel image can be captured by an image acquisition device installed at the entrance of the security checkpoint, such as a smart camera or webcam.

[0034] In this embodiment of the invention, an image acquisition device can be installed at the entrance of the security screening machine. The image acquisition device acquires images of people at the entrance of the security screening machine according to a set acquisition cycle and sends them to a processor used to control the speed adjustment of the security screening machine. After receiving the images, the processor performs image recognition to determine the number of people in the images, thereby determining the current flow of people at the entrance of the security screening machine, and flexibly adjusts the speed of the security screening machine based on the flow of people. Specifically, the processor can determine the current flow of people by performing image recognition for each received image, for example, by directly using the number of people in the image as the current flow of people; or it can determine the current flow of people based on the recognition results of multiple images, for example, by calculating the average number of people in multiple images as the current flow of people.

[0035] In a specific example, a smart camera installed at the entrance of the security checkpoint captures images of people every 2 seconds and sends the captured images to a processor. The processor can perform image recognition on each received image to determine the current flow of people.

[0036] S120. Adjust the running speed of the conveyor belt in the security inspection machine according to the current flow of people.

[0037] In this embodiment of the invention, after obtaining the current pedestrian flow, the operating speed of the conveyor belt in the security inspection machine can be adjusted according to the current pedestrian flow. Specifically, the correlation between the pedestrian flow range and the conveyor belt operating speed can be preset. After obtaining the current pedestrian flow, the pedestrian flow range to which the current pedestrian flow belongs is first determined. Then, based on the correlation between the pedestrian flow range and the conveyor belt operating speed, the corresponding conveyor belt operating speed is determined, and the conveyor belt is adjusted to that operating speed.

[0038] Specifically, after determining the current pedestrian flow, the current pedestrian flow can be compared with the pedestrian flow collected at the previous moment. If the current pedestrian flow is greater than the pedestrian flow at the previous moment, the speed of the conveyor belt will be increased; otherwise, the speed of the conveyor belt will be decreased.

[0039] In a specific example, such as Figure 1bAs shown, the smart camera at the security checkpoint entrance captures images of people and transmits them to the processor. The processor identifies the images to obtain the current pedestrian flow. When the current pedestrian flow is 0, the conveyor belt stops running and the security checkpoint's light source is turned off. When the current pedestrian flow is greater than 0 but less than the pedestrian flow threshold, the conveyor belt runs at a first speed. When the current pedestrian flow is greater than or equal to the pedestrian flow threshold, the conveyor belt runs at a second speed. The second speed is greater than the first speed.

[0040] In addition, the system can control the activation and deactivation of the light source in the security scanner based on the current flow of people. For example, the light source can be deactivated when the current flow of people is zero, and activated when the current flow of people is greater than zero.

[0041] The technical solution of this invention identifies the images of people at the entrance of the security inspection machine to determine the current flow of people at the entrance. Then, based on the current flow of people, the running speed of the conveyor belt in the security inspection machine is adjusted. This allows for advance adjustment of the conveyor belt speed according to the flow of people, solving the problem of lag in conveyor belt adjustment, saving energy, and improving security inspection efficiency.

[0042] Example 2

[0043] Figure 2a This is a flowchart of a speed adjustment method for a security inspection machine according to Embodiment 2 of the present invention. This embodiment further refines the above embodiment, providing specific steps for adjusting the running speed of the conveyor belt in the security inspection machine based on the current passenger flow. Figure 2a As shown, the method includes:

[0044] S210. By recognizing the images of people at the entrance of the security checkpoint, determine the current flow of people at the entrance of the security checkpoint.

[0045] S220. Determine the target operating speed associated with the current pedestrian flow.

[0046] In this embodiment of the invention, after determining the current pedestrian flow, the corresponding target operating speed is first determined based on the current pedestrian flow. Specifically, the correlation between the pedestrian flow range and the conveyor belt operating speed can be preset. After obtaining the current pedestrian flow, the pedestrian flow range to which the current pedestrian flow belongs is determined, and then the target operating speed corresponding to the current pedestrian flow is determined based on the correlation between the pedestrian flow range and the conveyor belt operating speed. The pedestrian flow and the conveyor belt operating speed are positively correlated, and the conveyor belt operating speed can be adjusted in advance based on the pedestrian flow. On the one hand, the operating speed can be slowed down when the pedestrian flow is low to save energy; on the other hand, the operating speed can be increased in advance when the pedestrian flow increases to improve security check efficiency.

[0047] Specifically, to avoid frequent speed adjustments to the conveyor belt and affecting its normal operation, the current pedestrian flow can be compared with the historical pedestrian flow at the previous data collection time. If the difference is greater than the difference threshold, it indicates that the current pedestrian flow has changed significantly compared to the previous time. In this case, the target operating speed associated with the current pedestrian flow can be determined based on the correlation between pedestrian flow and operating speed. If the difference is less than or equal to the difference threshold, it indicates that the current pedestrian flow has changed little compared to the previous time. In this case, the conveyor belt speed can be kept constant, and the current operating speed of the conveyor belt can be determined as the target operating speed.

[0048] Optionally, based on the current pedestrian flow, determine the target running speed associated with the current pedestrian flow, including:

[0049] Compare the current pedestrian flow with the historical pedestrian flow at the previous data collection time;

[0050] If the difference between the current pedestrian flow and the historical pedestrian flow is greater than the difference threshold, the target operating speed associated with the current pedestrian flow is determined based on the correlation between pedestrian flow and operating speed; the current pedestrian flow and the target operating speed are positively correlated.

[0051] If the difference between the current pedestrian flow and the historical pedestrian flow is less than or equal to the difference threshold, the current operating speed of the conveyor belt is determined as the target operating speed.

[0052] In this optional embodiment, a specific method is provided for determining the target operating speed associated with the current pedestrian flow: comparing the current pedestrian flow with the historical pedestrian flow at the previous data collection time. If the difference between the current pedestrian flow and the historical pedestrian flow is greater than a difference threshold, then the target operating speed associated with the current pedestrian flow is determined based on the correlation between pedestrian flow and operating speed; if the difference between the current pedestrian flow and the historical pedestrian flow is less than or equal to the difference threshold, the current operating speed of the conveyor belt is determined as the target operating speed, that is, keeping the conveyor belt operating speed unchanged, which can reduce the number of times the conveyor belt is adjusted and improve the stability of the conveyor belt operation.

[0053] For example, such as Figure 2bAs shown, the flow of people is determined by the first image captured by the smart camera. When the flow is zero, the conveyor belt and light source do not need to be started. When the flow is not zero, the target operating speed associated with the current flow can be determined based on the correlation between the flow and the operating speed. For example, the target operating speed is v1 when the flow is 1-n1, v2 when the flow is n1-n2, and v3 when the flow is n2-n3. Further, after the smart camera transmits the image of people captured at the next moment, the flow of people at the next capture moment is determined. The flow of people captured in the first capture is compared with the flow of people at the next capture moment. When the difference is less than or equal to a difference threshold, the current operating speed of the conveyor belt is determined as the target operating speed, i.e., the conveyor belt operating speed remains unchanged. When the difference is greater than the difference threshold, the target operating speed associated with the current flow is determined based on the correlation between the flow and the operating speed.

[0054] S230. Adjust the speed of the conveyor belt according to the current flow of people and the target operating speed.

[0055] In this embodiment of the invention, after determining the target operating speed of the conveyor belt, the operating speed of the conveyor belt is adjusted according to the target operating speed of the current pedestrian flow. Specifically, the conveyor belt can be directly adjusted to the target operating speed.

[0056] Considering the possibility of people not carrying luggage or bags, adjusting the conveyor belt speed solely based on pedestrian traffic could result in the conveyor belt operating at a low speed when pedestrian traffic is low, even though people are not carrying luggage or bags and therefore do not require security checks, leading to wasted resources. Therefore, a better approach would be to obtain the number of luggage and bags collected by the luggage and baggage collection module when pedestrian traffic is below a threshold, and then adjust the conveyor belt speed accordingly.

[0057] Optionally, the conveyor belt speed can be adjusted based on the current pedestrian flow and target operating speed, including:

[0058] If the current pedestrian flow is greater than or equal to the pedestrian flow threshold, adjust the operating speed of the conveyor belt to the target operating speed;

[0059] When the current pedestrian flow is less than the threshold, the number of luggage and parcels collected by the luggage and parcel collection module is obtained, and the running speed of the conveyor belt is adjusted according to the number of luggage and parcels and the target running speed.

[0060] In this optional embodiment, a specific method is provided for adjusting the operating speed of the conveyor belt based on the current passenger flow and the target operating speed, such as... Figure 2cAs shown: When the current passenger flow is greater than or equal to the passenger flow threshold, it indicates that the current passenger flow is large and there are many bags and packages that need to be checked. At this time, the speed of the conveyor belt is adjusted to the target speed that matches the current passenger flow to improve security check efficiency.

[0061] When the current pedestrian flow is less than the threshold, it indicates that the flow is low and there may be people not carrying luggage or bags. In this case, the number of luggage / bags collected by the luggage / baggage collection module can be obtained, and the conveyor belt speed can be adjusted based on this number and the target operating speed. For example, when the number of luggage / baggage is zero, the conveyor belt can be stopped to reduce unnecessary energy waste; when the number of luggage / baggage is not zero, the conveyor belt speed can be adjusted to the target operating speed that matches the current pedestrian flow.

[0062] Optionally, the conveyor belt speed can be adjusted based on the number of luggage packages and the target operating speed, including:

[0063] When the number of luggage packages is 0, control the conveyor belt to stop running;

[0064] If the number of luggage packages is not zero, adjust the conveyor belt speed to the target speed.

[0065] In this optional embodiment, a specific method is provided for adjusting the conveyor belt speed based on the number of luggage packages and the target operating speed: When the current pedestrian flow is less than the pedestrian flow threshold, it indicates that the current pedestrian flow is low, and there may be situations where people are not carrying luggage packages. At this time, the number of luggage packages can be further obtained, and the conveyor belt speed can be adjusted in combination with the number of luggage packages and the target operating speed. Specifically, when the number of luggage packages is 0, the conveyor belt is controlled to stop running; when the number of luggage packages is not 0, the conveyor belt speed is adjusted to the target operating speed.

[0066] Optionally, the technical solution of this embodiment also includes:

[0067] The initial running direction of the conveyor belt in the security inspection machine is determined by recognizing the images of people at both ports of the two-way security inspection machine.

[0068] If the baggage and parcel collection module detects baggage and parcels on the conveyor belt while personnel are passing through the first image acquisition range, it controls the conveyor belt to run along the initial running direction at a set speed for a first set time. The first image acquisition range includes the security checkpoint entrance that matches the initial running direction.

[0069] In this optional embodiment, when entering and exiting locations requiring high confidentiality, all luggage and parcels need to be inspected. The security inspection machine can be controlled to rotate in both directions. In this case, both ports of the security inspection machine could potentially serve as entry points; therefore, image acquisition devices are installed at both ports to capture images of people. After receiving the images of people captured by the image acquisition devices at both ports, the processor identifies the images and determines the initial running direction of the conveyor belt within the security inspection machine. Specifically, the port where people are first identified is designated as the entry point, meaning the initial running direction is from the port where people are first identified to the port where people are later identified.

[0070] Furthermore, if the baggage and parcel acquisition module detects baggage or parcels on the conveyor belt while personnel are passing through the first image acquisition range, it controls the conveyor belt to run along the initial running direction at a set speed for a first set time. The first image acquisition range refers to the acquisition range of the image acquisition device at the current entrance (the entrance matching the initial running direction), which includes the security checkpoint entrance matching the initial running direction.

[0071] For example, such as Figure 2d As shown, the security inspection machine includes two ports, A and B, and its conveyor belt can rotate in both directions. Smart cameras are installed at each port to capture images of people at those ports, with a capture range of L2. Each port also has a baggage / parcel placement area L1, each equipped with a baggage / parcel capture module to detect whether baggage / parcels are placed on the conveyor belt. The shortest distance from the baggage / parcel placement area to the security checkpoint of the machine is L3, thus the baggage / parcel inspection area is 2L3, and the conveyor line length is L4.

[0072] By recognizing personnel images at both ports of the two-way security scanner, if a person is first identified in the image acquired at port A, the initial running direction is determined to be from port A to port B. Furthermore, as the person passes through the first image acquisition range including port A, if the baggage / package acquisition module detects baggage / packages on the conveyor belt, the conveyor belt is controlled to run along the initial running direction at a set speed v1 for a first set time t5. Simultaneously, the security scanner's light source can also be turned on.

[0073] The required acceleration time for the conveyor belt is t1, the required time for the light source to start is t2, the time for the person to walk through the first image acquisition range is t3, the required time for the conveyor belt to stop rotating is t4, the first set time for the conveyor belt to run after detecting luggage is t6, and the time for placing luggage is t6.

[0074] Specifically, the operating speed v1 can be constrained by the light source start-up time, specifically: t2 ≤ (L3 - 1 / 2t1v1) / v1 + t1. The time it takes for a person to walk through the first image acquisition range is t3 = L2 / vperson + t6, which is at least (L2 - L1) / vperson, where vperson can be 1.1-1.5 m / s. The first set operating time is t5 = L4 / v1 to ensure that regardless of where the luggage or package is placed within the luggage / package placement range L1, it can be transported out of the conveyor belt within time t5.

[0075] Optionally, the technical solution of this embodiment also includes:

[0076] If the luggage and package acquisition module fails to detect luggage or packages on the conveyor belt while personnel are passing through the first image acquisition range, the conveyor belt will be controlled to run in the opposite direction of the initial running direction at a set speed for a second set time.

[0077] In this optional embodiment, if the luggage and package acquisition module does not acquire any luggage or packages on the conveyor belt during the process of personnel passing through the first image acquisition range, it indicates that there is no need to conduct security checks on the luggage and packages in the initial running direction. At this time, the conveyor belt is controlled to run in the opposite direction of the initial running direction to set the running speed and run for a second set time.

[0078] In addition, if personnel are detected at both ends simultaneously, one of the ports can be prioritized as the entrance to the security inspection machine based on the pre-set priority.

[0079] The equipment includes smart cameras installed at both ends of the security scanner's entrance and exit. These cameras provide full coverage of the conveyor belt when the camera's width is 0.3m from the entrance / exit, and coverage extends from 1.2m to 1.9m in height. These cameras are used to capture images of people to determine pedestrian flow. Safety light curtains are installed at both ends of the conveyor belt as luggage / package detection modules to detect the presence of such items. The conveyor belt is driven by electric rollers, which can be controlled by a driver to start, stop, reverse, and adjust speed. The cameras capture pedestrian flow information, and the safety light curtains detect whether luggage / packages are placed on the conveyor belt, determining the conveyor belt's operation and speed.

[0080] The technical solution of this invention identifies the images of people at the entrance of the security inspection machine to determine the flow of people at the entrance. Then, based on the current flow of people, a target running speed associated with the current flow of people is determined. Finally, the running speed of the conveyor belt is adjusted according to the current flow of people and the target running speed. The running speed of the conveyor belt in the security inspection machine can be adjusted in advance according to the flow of people. Compared with the method of the conveyor belt running at a constant speed, it can save energy and improve security inspection efficiency.
