[0034] The traffic participant can refer to a device that can be perceived by the roadside perception device and can communicate with the roadside perception device. For example, a vehicle, a smart bracelet, a mobile phone, a wearable device, etc.

[0035] In order to facilitate the description, the vehicle is used to illustrate the role of the traffic participant (smart bracelet, mobile phone, wearable device, etc.) in the present embodiment. Unless otherwise specified, the vehicle mentioned in the present embodiment can be considered as the traffic participant, and the traffic participant can also realize the function of the vehicle.

[0036] The roadside perception device is a device for roadside perception, which includes a roadside sensor, an edge computing module and a roadside communication module. The roadside sensor can be at least one of a laser radar, a camera and a millimeter wave radar, which is used to collect surrounding environmental information. The edge computing module is used to perform perception calculation on the environmental information collected by the roadside sensor, detect the target, and identify the category of the target, calculate the size, position, motion speed, heading angle and other information of the target.

[0037] The roadside communication module can be used to communicate with vehicles equipped with onboard terminals. Specifically, communication between the roadside sensing equipment and the vehicle refers to communication between the roadside sensing equipment and the vehicle's onboard terminal. The vehicle's onboard terminal includes onboard sensors, a perception computing module, and an onboard communication module. Optionally, in some cases, this onboard terminal can also be considered an intelligent terminal device on the vehicle, provided it possesses the following capabilities: the ability to communicate with the roadside sensing equipment and transmit vehicle traffic information to the roadside sensing equipment via a communication link. Onboard sensors include, but are not limited to, Global Navigation Satellite System (GNSS) receivers, Inertial Measurement Units (IMUs), and at least one of LiDAR, cameras, and millimeter-wave radar. GNSS receivers and IMUs provide information about the vehicle's own motion status. LiDAR, cameras, millimeter-wave radar, and other sensors provide onboard perception information. The perception computing module performs perception calculations on the information collected by the onboard sensors, detects targets, and calculates information such as the target's size, position, speed, and heading angle. The vehicle-mounted communication module is used to communicate with roadside sensing devices.

[0038] The roadside communication module and the vehicle-mounted communication module can be a 4G communication module, a 5G communication module, or a communication module that supports vehicle-to-everything (V2X) wireless communication technology, etc., and there are no restrictions here.

[0039] The edge computing module and the sensing computing module can be any module capable of data processing, such as a processor.

[0040] The target can be any object related to road / traffic activities, such as motor vehicles, pedestrians, non-motorized vehicles, smart bracelets, mobile phones, wearable devices, etc. The perceived information of the target can refer to its size, category, location, speed, heading angle, etc.

[0041] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0042] It should be understood that the size of the serial number of each step in the embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiment of the application.

[0043] In order to illustrate the technical solutions described in the present application, the following will be described by specific embodiments.

[0044] Referring to Figure 1 is the implementation flowchart of the perception information correction method provided by the embodiment of the present application, and the perception information correction method is applied to a roadside perception device. As Figure 1 shown, the perception information correction method can include the following steps:

[0045] Step 101, real-time acquisition of roadside perception information of the roadside perception device.

[0046] Among them, the roadside perception information includes but is not limited to the size, category, position, motion speed, heading angle and other information of the detected target.

[0047] The roadside perception information is obtained by the roadside perception device. Optionally, the roadside sensor in the roadside perception device can collect the environmental information around the roadside perception device, and the edge computing module in the roadside perception device can perform perception calculation on the environmental information collected by the roadside sensor to obtain the roadside perception information.

[0048] For example, the traffic participant is a vehicle, and the roadside perception device can provide the driver's blind area road condition information, over-the-horizon road condition information, vehicle decision and other services for the surrounding vehicles by real-time acquisition of roadside perception information.

[0049] Among them, real-time acquisition of roadside perception information can mean acquisition of roadside perception information at a preset time interval. For example, roadside perception information is acquired every 3 seconds.

[0050] Step 102, when determining that the target traffic participant enters the blind area of the roadside perception device, sending an information acquisition instruction to the target traffic participant, the information acquisition instruction being used to instruct the target traffic participant to acquire its own traffic information.

[0051] Among them, the blind area of the roadside perception device can mean the area where the roadside perception device cannot perceive the environmental information. The traffic information of the target traffic participant includes but is not limited to the size, category, position, motion speed, heading angle and other information of the target traffic participant.

[0052] When the target traffic participant enters the visual blind area of the roadside sensing device, the roadside sensing device cannot sense the traffic information of the target traffic participant. In order to provide the roadside sensing device with the traffic information of the target traffic participant in the visual blind area, the roadside sensing device can send an information acquisition instruction to the target traffic participant. After receiving the information acquisition instruction, the target traffic participant can acquire its own traffic information and feed back the traffic information to the roadside sensing device.

[0053] In step 103, the roadside sensing information is corrected according to the traffic information of the target traffic participant.

[0054] After receiving the traffic information fed back by the target traffic participant, the roadside sensing device can correct the real-time acquired roadside sensing information according to the traffic information of the target traffic participant, and complete the environmental information in the visual blind area of the roadside sensing device that cannot be sensed.

[0055] The number of target traffic participants in the visual blind area of the roadside sensing device can be one or at least two. Taking a target vehicle as an example, the roadside sensing device corrects the real-time acquired roadside sensing information according to the traffic information of all target vehicles in the visual blind area, which can solve the problem that the roadside sensing device cannot provide environmental information in the visual blind area to a large extent, and better provide the surrounding vehicles with the road condition information in the driver's visual blind area, the over-the-horizon road condition information, vehicle decision-making and other services.

[0056] In an embodiment, before the target traffic participant enters the visual blind area of the roadside sensing device, the method further comprises:

[0057] When it is detected that the target traffic participant is in the visual range of the roadside sensing device, a first target is determined from the roadside sensing information, and the target traffic participant is bound to the first target, the first target being a target in the roadside sensing information corresponding to the target traffic participant;

[0058] When it is detected that the first target disappears from the roadside sensing information, it is determined that the target traffic participant enters the visual blind area of the roadside sensing device.

[0059] When the target traffic participant is in the communication range of the roadside sensing device, the target traffic participant can communicate with the roadside sensing device to send its own traffic information to the roadside sensing device. After receiving the traffic information sent by the target traffic participant, the roadside sensing device can determine whether there is a target corresponding to the target traffic participant in the roadside sensing information according to the traffic information of the target traffic participant. If there is a target corresponding to the target traffic participant, it is determined that the target traffic participant is in the visual range of the roadside sensing device, and the target corresponding to the target traffic participant is determined from the roadside sensing information.

[0060] According to the traffic information of the target traffic participant, detecting whether the target corresponding to the target traffic participant exists in the roadside perception information can include: detecting whether information matching the traffic information of the target traffic participant exists in the roadside perception information, if the information matching the traffic information of the target traffic participant exists, it is determined that the target corresponding to the target traffic participant exists in the roadside perception information, and the target corresponding to the information matching the traffic information of the target traffic participant is the target corresponding to the target traffic participant; if the information matching the traffic information of the target traffic participant does not exist, it is determined that the target corresponding to the target traffic participant does not exist in the roadside perception information. Wherein, the matching of the traffic information of the target traffic participant can be matching all information in the traffic information of the target traffic participant, or matching part of the information in the traffic information of the target traffic participant, which is not limited here.

[0061] For example, if it is set that the matching of the traffic information of the target vehicle means matching the position and size of the target vehicle, when the position of the target vehicle is A and the size is B, if it is detected that the position of the target a in the roadside perception information is also A and the size is also B, it can be determined that the traffic information of the target vehicle matches the information of the target a in the roadside perception information, and the target a is the target corresponding to the target vehicle.

[0062] The binding of the target traffic participant and the first target can mean establishing a mapping relationship between the target traffic participant and the first target, that is, establishing a mapping relationship between the target traffic participant in the physical world and the target in the roadside perception information in the digital world.

[0063] Since the roadside perception information is acquired in real time, the first target may disappear from the roadside perception information. For example, it is detected that the first target exists in the roadside perception information acquired at a certain time, and the first target does not exist in the roadside perception information acquired at the next time, which can be determined as detecting that the first target disappears from the roadside perception information, and the target traffic participant enters the blind area of the roadside sensing device.

[0064] As shown in Figure 2a is an example diagram of the target vehicle driving in the field of view range of the roadside sensing device, vehicle 5 is the target vehicle, and Figure 2a It can be seen that vehicle 5 has not yet entered the blind area of the roadside sensing device at this time; as shown in Figure 2b is an example diagram of vehicle 5 driving into the blind area of the roadside sensing device, because vehicle 4 blocks vehicle 5, vehicle 5 drives into the blind area of the roadside sensing device, and the roadside sensing device cannot perceive the traffic information of vehicle 5, and the present application can provide the traffic information of vehicle 5 for the blind area of the roadside sensing device.

[0065] Optionally, the roadside perception device can also use a correlation algorithm (such as a Kalman filter algorithm) to predict the trajectory of the target it perceives, and based on the predicted trajectory, it can be known in advance that a traffic participant will enter the blind area of the roadside perception device. In some embodiments, if it is predicted that a certain traffic participant (first target) will enter the blind area, it is determined that the first target is detected to disappear from the roadside perception information. At this time, based on the prediction result, an information acquisition instruction can be sent to the traffic participant entering the blind area of the roadside perception device.

[0066] In an embodiment, the roadside perception information is corrected according to the traffic information of the target traffic participant, including:

[0067] The first target is recovered in the roadside perception information according to the traffic information of the target traffic participant.

[0068] When the target traffic participant enters the blind area of the roadside perception device, the first target does not exist in the roadside perception information. After receiving the traffic information of the target traffic participant, the roadside perception device can recover the first target corresponding to the target traffic participant in the roadside perception information according to the traffic information of the target traffic participant, thereby providing the roadside perception device with the traffic information of the target traffic participant in the blind area of the roadside perception device, and supplementing the perception information of the first target (i.e., the traffic information of the target traffic participant) in the roadside perception information, thereby improving the problem of target missing detection.

[0069] In an embodiment, the first target is recovered in the roadside perception information according to the traffic information of the target traffic participant, including:

[0070] The traffic information of the target traffic participant is added to the roadside perception information to recover the first target in the roadside perception information.

[0071] Wherein, the recovery of the first target in the roadside perception information can be understood as being able to detect the first target corresponding to the target traffic participant from the roadside perception information.

[0072] After the traffic information of the target traffic participant is added to the roadside perception information, the first target corresponding to the target traffic participant can be detected from the roadside perception information, thereby realizing the recovery of the first target in the roadside perception information.

[0073] The embodiments of the present application, when determining that the target traffic participant enters the blind area of the roadside perception device, can send an information acquisition instruction to the target traffic participant, instructing the target traffic participant to acquire its own traffic information. According to the traffic information of the target traffic participant, the roadside perception information can be corrected, thereby providing the roadside perception device with environmental information in the blind area of the roadside perception device.

[0074] Referring to Figure 3 is a flowchart of an implementation of the perception information correction method provided in Embodiment Two of the present application, which is applied to a roadside perception device. As shown in Figure 3 , the perception information correction method can include the following steps:

[0075] Step 301: Real-time acquisition of roadside perception information of the roadside perception device.

[0076] This step is the same as step 101, and specific reference can be made to the related description of step 101 above, which will not be repeated here.

[0077] Step 302: When it is determined that the target traffic participant enters the visual blind area of the roadside perception device, an information acquisition instruction is sent to the target traffic participant, the information acquisition instruction being used to instruct the target traffic participant to acquire its own traffic information and the traffic information of other traffic participants.

[0078] This step is partly the same as step 102, and specific reference can be made to the related description of step 102 above, which will not be repeated here.

[0079] In addition, when the target traffic participant receives the information acquisition instruction, it can acquire its own traffic information (i.e., the traffic information of the target traffic participant) and the traffic information of other traffic participants, and feed back the traffic information of the target traffic participant and the traffic information of other traffic participants to the roadside perception device.

[0080] For example, the traffic participant is a vehicle, and the target vehicle can perceive the traffic information of other vehicles through sensors such as laser radar, camera, millimeter wave radar, etc. in the vehicle terminal.

[0081] Step 303: Correction of the roadside perception information according to the traffic information of the target traffic participant and the traffic information of other traffic participants.

[0082] According to the traffic information of the target traffic participant, the target and the related information of the target that cannot be perceived in the visual blind area of the roadside perception device can be completed, and the problem of target missing detection can be improved; according to the traffic information of other traffic participants, the roadside perception information can be further corrected, and the problem of decision-making misjudgment can be improved.

[0083] In an embodiment, the correction of the roadside perception information according to the traffic information of other traffic participants includes:

[0084] Detection of whether a second target exists in the roadside perception information, the second target being a target corresponding to other traffic participants;

[0085] If the second target exists, traffic information of other traffic participants is fused with the perception information of the second target in the roadside perception information to obtain fused perception information.

[0086] If the second target does not exist, the traffic information of other traffic participants is added to the roadside perception information.

[0087] The presence or absence of the second target in the roadside perception information can be detected according to the traffic information of other traffic participants. Specifically, it includes: detecting whether there is information matching the traffic information of other traffic participants in the roadside perception information. If there is information matching the traffic information of other traffic participants, it is determined that the second target exists in the roadside perception information, and the target corresponding to the information matching the traffic information of other traffic participants is the second target. If there is no information matching the traffic information of other traffic participants, it is determined that the second target does not exist in the roadside perception information. Wherein, the matching with the traffic information of other traffic participants can be matching with all information in the traffic information of other traffic participants, or matching with part of the information in the traffic information of other traffic participants, which is not limited here.

[0088] When the second target exists in the roadside perception information, the roadside perception information obtained by the roadside perception device can be corrected by fusing the traffic information of other traffic participants corresponding to the second target with the perception information of the second target in the roadside perception information, to obtain more accurate and comprehensive roadside perception information. Wherein, confidence weighting, Kalman filtering and the like can be used for information fusion.

[0089] When the second target does not exist in the roadside perception information, the traffic information of other traffic participants corresponding to the second target can be added to the roadside perception information to provide the roadside perception device with traffic information of other traffic participants that cannot be perceived in the visual blind area.

[0090] The embodiment of the present application is based on the embodiment one, and by sending an information acquisition instruction to the target traffic participant, instructing the target traffic participant to further perceive the traffic information of other traffic participants, the roadside perception information can be further corrected according to the traffic information of other traffic participants, and more accurate and comprehensive roadside perception information can be provided for the roadside perception device.
