Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
Example 1
In the present embodiment, a control apparatus is provided. As used below, the term "module" may be a combination of software and/or hardware that implements a predetermined function. Although the means described in the embodiments below are preferably implemented in a combination of software and hardware, an implementation in software is also possible and contemplated.
Fig. 1 is a block diagram of a control apparatus according to an embodiment of the present invention, as shown in fig. 1, the apparatus including:
a target identification module 11 for identifying a category of a target object;
and the control module 13 is configured to obtain a category of the target object, and determine whether to allow the target object to pass according to the attribute information of the target object when the category is a specified category.
Through the above modules, the target identification module is used for identifying the category of the target object; the control module is used for acquiring the category of the target object, and determining whether the target object is allowed to pass according to the attribute information of the target object under the condition that the category is the designated category, so that the problems of low pass management accuracy and potential safety hazard in the related technology are solved, the pass management accuracy can be improved, and the safety is improved.
For example, in a scenario where it is necessary to control the vehicle to pass through, the specified category may be a vehicle, and in the case where the target object is a vehicle, it is determined whether the vehicle is allowed to pass through again according to the attribute information of the vehicle; in the case where the target object is a person, since "person" is not a specified category, the person is not allowed to pass.
For example, in a scene that people need to be controlled to pass through, the specified category may be a person, and in the case that the target object is a person, whether the person is allowed to pass through is determined according to the attribute information of the person; in the case where the target object is a vehicle, since "vehicle" is not a specified category, the vehicle is not allowed to pass.
In an optional embodiment, the target identification module is further configured to identify position information of the target object, and send the position information to the control module; the control module is further configured to determine whether the target object is located in a preset area according to the location information, wherein if the location information indicates that the target object is located in the preset area, whether the target object is allowed to pass is determined according to the attribute information of the target object.
It should be noted that, for example, the preset area may be an area close to the passage opening, and when the target object is in the preset area, it indicates that the target object may have an intention or a trend of passage, in this case, and then determines whether to allow the target object to pass according to the attribute information of the target object, and unnecessary determination steps may be reduced to save computing resources and storage resources. For example, if the target object does not have the intention or tendency to pass through, but determines whether to allow the target object to pass through according to the attribute information of the target object, additional storage resources and computing resources are necessarily occupied.
In an alternative embodiment, the apparatus further comprises: the identity acquisition module is used for acquiring identity information of the target object and sending the identity information to the control module, wherein the attribute information comprises the identity information of the target object; the control module is also used for identifying the identity information of the target object and determining whether the target object is allowed to pass according to whether the identity information of the target object is matched with preset identity information; wherein, under the condition that the identity information is matched with the preset identity information, the target object is determined to be allowed to pass; and determining that the target object is forbidden to pass under the condition that the identity information does not match with the preset identity information.
It should be noted that, for example, in the case that the target object is a vehicle, the identity information of the target object may be embodied by a license plate number, and the identity information acquired by the identity acquisition module may be a picture of the license plate number; when the target object is a person, the identity information of the target object can be embodied by contents such as a face, a badge, a uniform and the like, and the identity information acquired by the identity acquisition module can be an image of the contents such as the face, the badge, the uniform and the like.
In an optional embodiment, the identity acquiring module is further configured to acquire the identity information of the target object when a preset condition is met, where the preset condition includes: the category of the target object is the specified category. It should be noted that, in the case that the category of the target object is the designated category, the re-collecting of the identity information of the target object may save storage resources, and if the target object is not the designated category, which may indicate that the target object is not an object concerned by traffic control, it is not necessary to collect the identity information of the target object.
In an optional embodiment, the target identification module is further configured to collect spatial information of the target object, and send the spatial information to the control module, where the attribute information further includes the spatial information of the target object; the control module is further configured to determine whether the spatial information matches preset spatial information according to the spatial information of the target object; allowing the target object to pass through under the condition that the spatial information is matched with the preset spatial information; and if the space information does not match with the preset space information, forbidding the target object to pass. It should be noted that the spatial information may refer to a situation of a space occupied by the target object, for example, the content such as the size information of the target object, and for the vehicle, the size information of the vehicle may be the content such as the vehicle width and the vehicle height. Since the passage opening has some spatial limitations (corresponding to the above-mentioned "preset spatial information"), such as height limitations, width limitations, etc., in some cases, the spatial information of the target object can be collected to determine whether the target object can pass through the passage opening. If the space information of the target object meets the space limitation requirement of the passage port, the target object can pass through the passage port, and if the space information of the target object does not meet the space limitation requirement of the passage port, the target object cannot pass through the passage port.
In an alternative embodiment, the apparatus further comprises: the barrier gate controller is used for receiving the passing signal and controlling the barrier gate to be opened according to the passing signal; the control module is also used for sending the passing signal to the gateway controller under the condition that the target object is determined to be allowed to pass. It should be noted that, if the control module determines that the target object can pass through, a pass signal may be sent to the gateway controller to indicate that the gateway controller can control the gateway to be lifted or opened so as to enable the target object to pass through.
In an optional embodiment, the target identification module is further configured to collect motion state information of the target object, and send the motion state information to the control module; the control module is also used for determining the sending time of the traffic signal according to the motion state information.
It should be noted that the motion state information may include information such as a distance and a speed of the target object, and the sending time of the traffic signal may be determined according to the information, so as to control the opening time of the traffic port, for example, when the target object runs faster and is closer to the traffic port, the traffic signal may be sent earlier, so as to open the traffic port as soon as possible; when the target object runs at a lower speed and is far away from the traffic opening, the traffic signal can be sent properly at a later time, and the traffic opening is not opened urgently.
In an alternative embodiment, the apparatus further comprises: the alarm is used for receiving the alarm signal and giving an alarm according to the alarm signal; the control module is also used for sending the alarm signal to the alarm under the condition that the target object is determined to be forbidden to pass. It should be noted that, if the control module determines that the target object is not passable, an alarm signal may be sent to the alarm to instruct the alarm to alarm so as to attract the attention of the administrator, and further, whether the target object is allowed to pass or not may be determined manually.
In an optional embodiment, the target identification module and the identity acquisition module are disposed on the same board, or the target identification module and the identity acquisition module are disposed on two interconnected boards, respectively. It should be noted that, if the target identification module and the identity acquisition module are disposed on the same board, the communication efficiency between the target identification module and the identity acquisition module may be improved, and the information interaction manner between the target identification module and the identity acquisition module may also be increased, for example, the target identification module and the identity acquisition module may interact with each other in more information types or information formats.
In an alternative embodiment, the target recognition module and the identity acquisition module operate in the same direction. It should be noted that, in general, the target object to which the target identification module and the identity acquisition module operate is the same target object, so the operating directions of the target identification module and the identity acquisition module may be the same.
In an alternative embodiment, the identity acquisition module may be a camera, for example, the identity acquisition module may include: a lens for photographing the target object; and the image sensor is used for generating an identity image of the target object, and the identity image is used for indicating the identity information of the target object.
In an alternative embodiment, the object recognition module includes a millimeter wave radar chip.
In an alternative embodiment, the millimeter wave radar chip may be a broad beam radar, for example, a millimeter wave radar chip having an operating beam width greater than or equal to 90 °.
It should be noted that the above modules may be implemented by software or hardware or a combination of the two, for example, but not limited to, the following manners: the modules are all positioned in the same processor; alternatively, the modules are respectively located in different processors in any combination.
The present embodiment also provides a control method that can be operated in the control device, and of course, can also be operated in other devices. Fig. 2 is a flowchart of a control method according to an embodiment of the present invention, as shown in fig. 2, the flowchart includes the steps of:
step S202, identifying the category of the target object;
and step S204, determining whether the target object is allowed to pass according to the attribute information of the target object under the condition that the category is the designated category.
Through the steps, the category of the target object is identified, and whether the target object is allowed to pass is determined according to the attribute information of the target object under the condition that the category is the designated category, so that the problems of low pass management accuracy and potential safety hazards in the related technology are solved, the pass management accuracy can be improved, and the safety is improved.
For example, in a scenario where it is necessary to control the vehicle to pass through, the specified category may be a vehicle, and in the case where the target object is a vehicle, it is determined whether the vehicle is allowed to pass through again according to the attribute information of the vehicle; in the case where the target object is a person, since "person" is not a specified category, the person is not allowed to pass.
For example, in a scene that people need to be controlled to pass through, the specified category may be a person, and in the case that the target object is a person, whether the person is allowed to pass through is determined according to the attribute information of the person; in the case where the target object is a vehicle, since "vehicle" is not a specified category, the vehicle is not allowed to pass.
Alternatively, the main body of the above steps may be a controller, a processor, etc., but is not limited thereto.
Optionally, before the determining whether to allow the target object to pass according to the attribute information of the target object, the method further includes: identifying position information of the target object, and determining whether the target object is located in a preset area according to the position information, wherein in the case that the position information indicates that the target object is located in the preset area, determining whether the target object is allowed to pass according to the attribute information of the target object.

For example, if the target object does not have the intention or tendency to pass through, but determines whether to allow the target object to pass through according to the attribute information of the target object, additional storage resources and computing resources are necessarily occupied.

Optionally, the method includes acquiring identity information of the target object when a preset condition is met, where the preset condition includes: the category of the target object is the specified category. It should be noted that, in the case that the category of the target object is the designated category, the re-collecting of the identity information of the target object may save storage resources, and if the target object is not the designated category, which may indicate that the target object is not an object concerned by traffic control, it is not necessary to collect the identity information of the target object.

Fig. 5 shows an external mounting structure according to an alternative embodiment of the present invention, as shown in fig. 5, in which a radar module and an image sensor module are respectively mounted on two single boards, and the modules can be made small because the millimeter wave radar module uses a chip with an internal antenna. The radar module transmits the acquired data to the image sensor module through a high-speed signal (also may be an Inter-Integrated Circuit Bus (I2C), a Controller Area Network (CAN), a Receiver/Transmitter (UART), etc.) such as a Serial Peripheral Interface (SPI), etc., and then through a Flexible Printed Circuit (FPC) or a Flexible Flat Cable (FFC) line, and the data Bus on the image sensor and the image signal are processed by the MCU of the camera together. The structure has the advantages that the installation position of the radar module is more free, the radar module can be installed on the lens cover or the shell, but the radar module needs to meet several requirements that 1, the direction of the radar module is the same as that of the lens; 2. the radar module can not be provided with a metal shelter in front of the radar module, and can be provided with a plastic or glass lens cover. The use of connecting wires may affect the integrity of the signal.

The structure has the advantages that the placing position of the radar chip is fixed, no metal shielding object is arranged in front of the chip, no connecting wire is used, and the quality of signals is improved. Fig. 7 is a schematic structural diagram of a camera lens cover corresponding to an embedded single board structure according to an alternative embodiment of the present invention, and as shown in fig. 7, since a radar chip and an image sensor chip are placed on the same single board, the camera lens cover becomes wider, which results in widening of the arrangement of the camera, and the image sensor cannot use a larger lens, because a distance close to the radar chip may have a certain effect on a radar echo signal.
Fig. 8 is a schematic workflow diagram of a triggering device according to an alternative embodiment of the present invention, and as shown in fig. 8, a specific workflow of the device includes: after the equipment is powered on, all modules start to work, and the radar detects whether targets such as people and vehicles exist in a detection area or not. When the radar detects that a target approaches, whether the nearest target is a vehicle or a non-vehicle is judged, if the target is the non-vehicle, an alarm is given to remind of leaving, firstly, people are prevented from entering a barrier gate area and being easily smashed by mistake, and secondly, a driver on the vehicle is prevented from opening the barrier gate by printing a license plate or a mobile phone photo and the like. And only when the radar detects that the nearest target is the vehicle, the camera is triggered to capture the license plate. And the camera MCU obtains the license plate image acquired by the image sensor and the vehicle position and height information acquired by the radar to perform admission judgment. The position information of the vehicle is collected to enable the MCU to identify the license plate image after the vehicle enters the detection area, and the height information of the vehicle is collected to ensure that the height of the vehicle does not exceed the height limit of the entrance. After the access is passed, the camera raises the signal for a barrier gate rod of the barrier gate control panel, and if the access is not passed, the vehicle is judged by the manual work to enter the park.

When the person is in front of the vehicle, the camera cannot be triggered to take a picture, and the person can be warned to leave the barrier area.
Compared with the scheme of laterally mounting the narrow-beam trigger radar, the scheme of the wide-beam normally-mounted radar greatly increases the point cloud number of echo signals, so that people and vehicles can be identified, and people are prevented from being in front of the vehicles when the vehicles drive in. And the height signal of the vehicle is collected, and the height of the vehicle is judged and early warning is achieved when the vehicle does not enter.
This embodiment compares in using infrared range unit to trigger the scheme that the camera carries out license plate discernment, and this proposal uses millimeter wave radar, can solve infrared range unit and receive the influence of weather, light and shelter from the thing, accomplishes full weather, and the use of total environment increases the stability in the use. And the millimeter wave radar can be used for multidimensional measurement of human-vehicle identification, vehicle distance, vehicle speed, vehicle height and the like, and can be used for various specific use environments.
This embodiment compare with split type radar camera scheme, the radar camera scheme of the integral type that this embodiment used can transmit the position of current target through high signal such as the SPI in the board, and the height, information such as people still car are handled for MCU, have solved split type radar camera and can only transmit the shortcoming of on-off information. And the millimeter wave radar chip with the built-in antenna is used, so that the volume of the radar module is greatly reduced, and the cost is also reduced.
