Detailed Description
Exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Referring to fig. 1, fig. 1 is a flowchart of a data correction method according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:
step 101: and obtaining road side perception data of the target unmanned vehicle.
In this embodiment, the target unmanned vehicle may be a vehicle that travels on an intersection, road, or the like. The target drone may be one vehicle or multiple vehicles. The road side perception data of the target unmanned vehicle can be obtained by a road side perception system through road side detection.
Alternatively, the execution subject of the data correction method of the present embodiment may be a roadside computing device (or referred to as a roadside computing unit). The roadside computing device may be a component of the roadside sensing system, or may be a computing device independent of the roadside sensing system, which is not limited in this embodiment.
Step 102: and processing the road side perception data according to a preset transformation matrix to obtain target correction data of the target unmanned vehicle.
In this embodiment, the preset transformation matrix may be calculated by using the road side sensing data and the true value data of the multiple sample unmanned vehicles, and used for subsequently correcting (or called correcting and precision compensating) the road side sensing data of the target unmanned vehicles, so as to improve the road side sensing precision. For example, the plurality of sample drones may be selected to be 3, 4, etc.
In one embodiment, the road side sensing data of the sample unmanned vehicle can be detected by a road side sensing system through the road side. The truth value data of the sample unmanned vehicle can be obtained by self simulation through positioning operation. It can be appreciated that the positional information obtained by vehicle positioning, etc. is generally highly accurate and thus can be used as a true value reference.
In the application scenario of this embodiment, the sample unmanned vehicle and the target unmanned vehicle may be driven sequentially through the same intersection. That is, after the change matrix is calculated by using the road side sensing data and the truth value data of the (sample) unmanned vehicle which is driven through the intersection, the road side sensing data of the (target) unmanned vehicle which is driven through the intersection is processed, namely, the accuracy compensation is performed according to the change matrix, so that the accuracy of the road side sensing data of the subsequent unmanned vehicle is improved.
According to the data correction method, the road side perceived data of the target unmanned aerial vehicle is processed according to the preset transformation matrix to obtain the target correction data, and the road side perceived data of the target unmanned aerial vehicle can be corrected, so that the technical problem that the accuracy of the road side perceived data of the existing unmanned aerial vehicle is low is solved, and the accuracy of the road side perceived data is improved.
In this embodiment of the present application, since the position of the unmanned vehicle may be calibrated by means of the center point and the corner point, the road side sensing data of the sample unmanned vehicle may include: the position coordinate sets of the center point and the corner point of the sample unmanned vehicle are obtained through road side detection; the truth data of the sample unmanned vehicle comprises: and through positioning operation, obtaining a position coordinate set of the center point and the corner point of the sample unmanned vehicle. Therefore, the unmanned vehicle can be accurately calibrated, and the accuracy of a preset transformation matrix is ensured.
Optionally, before step 101, the method may further include:
obtaining road side perception data of a plurality of sample unmanned vehicles;
acquiring truth value data of a plurality of sample unmanned vehicles;
and calculating a transformation matrix between the road side perception data and the true value data of the plurality of sample unmanned vehicles based on an iterative closest point (Iterative Closest Point, ICP) algorithm to obtain the preset transformation matrix.
The ICP algorithm is an iterative calculation method, is mainly used for accurately splicing depth images in computer vision, and can be realized by continuously iterating and minimizing corresponding points of source data and target data. Based on the above, when the preset transformation matrix is calculated, the ICP algorithm can be used for matching the corresponding points of the road side perception data and the corresponding points of the true value data of the sample unmanned vehicle, so that the road side perception data is infinitely close to the true value data, and the transformation matrix between the road side perception data and the true value data is obtained.
In this embodiment, since the 3D error of the sensing module in the road side sensing system, such as the camera, caused by the internal and external parameters and the ground equation, accords with the european transformation, the following model formula may exist to enable the road side sensing data transformation of the sample unmanned vehicle to project to the true value data:
P2 i ＝RP1 i +t+e i (1)
wherein P1 i Representing a position coordinate set of a center point and a corner point of the sample unmanned vehicle i obtained through positioning operation simulation, P2 i Position coordinate set representing center point and corner point of sample unmanned vehicle i obtained by road side detection, R and t represent European transformation, and e i Representing a human labeling error, which may conform to a gaussian distribution.
In one embodiment, after obtaining the road side sensing data (the position coordinate set of the center point and the edge corner point obtained by road side detection) and the truth value data (the position coordinate set of the center point and the edge corner point obtained by positioning operation simulation) of the plurality of sample unmanned vehicles, ICP solving can be performed by using a singular value decomposition (Singular Value Decomposition, SVD) mode according to the above formula (1), and accurate splicing is achieved by continuously iterating the corresponding points of the road side sensing data and the truth value data so as to obtain R and t, thereby obtaining a transformation matrix between the road side sensing data and the truth value data of the sample unmanned vehicles.
Note that, in this embodiment, the method of calculating the transformation matrix between the road side sensing data and the truth value data of the sample unmanned vehicle is not limited, and an existing method, for example, the above-mentioned ICP solving method using the SVD method may be adopted.
Optionally, the process of acquiring the truth data of the plurality of sample unmanned vehicles may include:
and respectively receiving true value data sent by each sample unmanned aerial vehicle, wherein the true value data is obtained by the sample unmanned aerial vehicle through positioning operation.
In this way, since the general accuracy of the positional information and the like obtained by the vehicle positioning is high, the accuracy of the preset transformation matrix can be ensured by taking the data obtained by the positioning operation as the true value data.
It should be noted that, the truth data may be actively sent to the roadside computing device by the sample unmanned vehicle when the sample unmanned vehicle passes through a specific location, or may be sent to the roadside computing device by the sample unmanned vehicle after receiving the related information. The related information may be request information sent by the road side computing device and used for requesting true value data, or a road side sensing message broadcast by the road side sensing system, where the road side sensing message includes all obstacle (vehicle) information sensed by the road side sensing system, so that after the sample unmanned aerial vehicle receives the obstacle information, the sample unmanned aerial vehicle discovers information belonging to the sample unmanned aerial vehicle based on the main vehicle discovery model, and returns the true value information obtained through positioning operation and matched obstacle information to the road side computing device.
Embodiments of the present application are described in detail below in conjunction with fig. 2 and 3.

The first V2X transmitting module 12 is configured to broadcast the road side sensing information detected by the sensing module 11, so as to be received by each unmanned vehicle 2 in the intersection.
As shown in fig. 2, the drone vehicle 2 (which may also be referred to as a host vehicle 2) may include a second V2X receiving module 21, a host vehicle discovery module 22, and a positioning module 23. The second V2X receiving module 21 is configured to receive the road side sensing information broadcast by the first V2X transmitting module 12. The host vehicle discovery module 22 is configured to discover information pertaining to itself from the received obstacle-vehicle information. The positioning module 23 is configured to obtain positioning information (sensing information detected by a road side is distinguished from the sensing information, which is simulated by the positioning operation) of the unmanned vehicle 2 through a positioning operation, where the accuracy of the information is high, and the information can be used as a true value reference and called true value information, and at least includes position coordinate data of a center point and a corner point thereof. It can be understood that, for single-target tracking, because the accuracy of the road side perception information is limited, if the unmanned vehicle 2 adopts the road side perception information to discover, the error is abnormally large; and because the accuracy of the information simulated by the positioning operation is high, the error is small if the unmanned vehicle 2 adopts the simulated information for discovery.
Further, as shown in fig. 3, the drone 2 (such as the host vehicle a, host vehicle B, and host vehicle C shown in fig. 3, which correspond to the sample drone) may also include a second V2X sending module 24. The second V2X sending module 24 may be configured to send back, to the road side computing device 3, the positioning information obtained by the positioning module 23, the self-size, and the road side perceived information matched by the host vehicle discovery module 22 through V2I (vehicle to infrastructure), so that the road side computing device 3 calculates a transformation matrix for compensating, i.e. correcting, the accuracy of the road side perceived information.
In one embodiment, the information (or referred to as host vehicle obstacle information) sent by the second V2X sending module 24 may include the following necessary fields:
1) id: identification of the host vehicle;

8) polygon_point: corner points of the main vehicle contour, such as point coordinates in the world coordinate system: x, Y and Z;
9) type: types of host vehicles, including: unknown, unknown motion, unknown stationary, non-motor vehicle, pedestrian, etc.
As shown in fig. 3, the roadside computing device 3 may include a first V2X receiving module 31 and an accuracy compensation module 32. The first V2X receiving module 31 is configured to receive the information sent by the second V2X sending module 24. The accuracy compensation module 32 is configured to match road side sensing information (such as a set of position coordinates of a center point and a corner point obtained by road side sensing) and positioning information (such as a set of position coordinates of a center point and a corner point obtained by positioning operation) of a plurality of sample unmanned vehicles such as a host vehicle a, a host vehicle B, and a host vehicle C to obtain a transformation matrix, and correct road side sensing information of an obstacle vehicle detected by the road side sensing system 1 by using the transformation matrix, so that corrected data approximates to a true value, and return the corrected data to the road side sensing system 1. Alternatively, the roadside computing device 3 may be an integral part of the roadside perception system 1, or may exist independently of the roadside perception system.
