All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The visual perception algorithm optimization method and system of the present invention are described below with reference to fig. 1-5.
The visual perception algorithm is a computer program stored in a vehicle-mounted host of the automatic driving vehicle, and can process images and videos shot by a camera of the vehicle and perceive objects such as obstacles, lane lines and the like, so that the vehicle can be controlled to feed back in time.
As shown in fig. 1 and 2, the present invention provides a visual perception algorithm optimization method, including: as follows from step 110 to step 150.
And step 110, acquiring real data and simulation data, and acquiring vehicle state simulation information.
It is understood that a simulation test platform may be provided, and the simulation test platform may include a data generation unit, a data preprocessing unit, a vehicle state information unit, a perception algorithm verification and processing unit, and a control planning unit. The data generation unit can acquire real data and simulation data, the real data can be an environment real-time image or a real-time video shot by a camera in an actual scene, and the simulation data is an environment image or an environment video simulated by the data generation system.
The camera can be a short-focus camera, a long-focus camera or a fisheye camera.
The vehicle state simulation information is related information which is simulated by the vehicle state information unit according to the vehicle state information possessed by the vehicle running in a real scene, the vehicle state information unit can generate vehicle state simulation information, and the vehicle state simulation information is a simulated data form.
And 120, loading a visual perception algorithm based on the real data, the simulation data and the vehicle state simulation information to generate a perception performance index.
It can be understood that the real data, the simulation data and the vehicle state simulation information can be input into the perception algorithm verifying and processing unit, and the visual perception algorithm is loaded in the perception algorithm verifying and processing unit, that is, the real data, the simulation data and the vehicle state simulation information are processed by using the visual perception algorithm, so as to simulate the actual process of the operation of the visual perception algorithm in the actual driving scene.
After the visual perception algorithm is operated, obstacle information attributes can be obtained firstly, the obstacle information attributes can comprise a target ID, a target category, the width and the height of the target, the confidence coefficient of the target and the center coordinate of the target, and the information attributes of the lane line comprise lane line quality (confidence coefficient), lane line type and cubic polynomial fitting parameters (C0, C1, C2 and C3).
The obstacle information attribute may be converted into a perceptual performance index, which may include: AP (single category evaluation accuracy) for obstacle detection, maps (average of multiple categories of APs), fps (frame rate), lane line detection index p (accuracy).
And step 130, confirming that the perception performance index is smaller than the performance index threshold value, and training the visual perception algorithm based on the real data and the simulation data to obtain an updated visual perception algorithm.
It can be understood that a performance index threshold value can be set, the perception performance index is compared with the performance index threshold value, if the perception performance index is greater than or equal to the performance index threshold value, the visual perception algorithm is considered to pass the verification, at this moment, the visual perception algorithm is not updated, the visual perception algorithm can be output to the fusion module and the post-processing unit, namely, the visual perception algorithm is directly stored for subsequent use and operation.
And if the perception performance index is smaller than the performance index threshold value, the visual perception algorithm is considered to need to be optimized and updated, the visual perception algorithm is trained by utilizing real data and simulation data, so that the parameters of the visual perception algorithm are adjusted, and the updated visual perception algorithm is obtained based on the adjusted parameters of the visual perception algorithm.
It should be noted that the performance index threshold is an evaluation index corresponding to the visual perception algorithm, different visual perception algorithms correspond to different performance index thresholds, and the performance index thresholds can be set according to actual requirements, which is not specifically limited in this embodiment.
And 140, inputting the updated visual perception algorithm to the control and planning unit to obtain a feedback result.
It can be understood that the control and planning unit can simulate the working state of the execution element in the actual driving scene of the vehicle, respond to the input updated visual perception algorithm to obtain a feedback result, and perform secondary evaluation on the updated visual perception algorithm according to the feedback result.
The feedback result may include: the data obtained by the control and planning unit based on the preset feedback threshold value determines whether the result provided by the updated visual perception algorithm is appropriate, and if not, the perception algorithm is further optimized, and corresponding parameters are optimized.
And 150, confirming that the feedback result is not in the feedback threshold range, iteratively loading the updated visual perception algorithm through the real data, the simulation data and the vehicle state simulation information until the feedback result is in the feedback threshold range, and outputting the target visual perception algorithm.
It can be understood that a feedback threshold value can be preset, the feedback result is compared with the feedback threshold value, if the feedback result is within the range of the feedback threshold value, the updated visual perception algorithm is considered to meet the requirement, and at the moment, the updated visual perception algorithm is output to the fusion and post-processing module as a target visual perception algorithm; if the feedback result is not within the feedback threshold range, the updated visual perception algorithm is not considered to meet the requirement, the updated visual perception algorithm is iteratively loaded through the real data, the simulation data and the vehicle state simulation information, namely the processes from the step 120 to the step 150 are repeatedly executed until the obtained feedback result is within the feedback threshold range, and the updated visual perception algorithm meeting the requirement is output as the target visual perception algorithm.
The feedback threshold may be an interval value, and if the feedback result is not within the interval range, the iterative loading operation is performed until the feedback result obtained by the iterative iteration is within the interval range.
Therefore, through the verification and iteration process, the multiple evaluation of the visual perception algorithm is realized, the optimization of the output target visual perception algorithm is realized, and the automatic driving is safer and more efficient.
It is worth mentioning that the visual perception algorithm optimization method can be directly executed in a simulation test platform, the simulation test platform can run in a terminal device and is used for verifying and optimizing the visual perception algorithm, when the visual perception algorithm is optimized, the simulation test platform does not need to be connected with a server or a mobile terminal, other devices are not needed for assisting detection, the simulation test platform can be directly executed in sequence according to the steps of the method, and the optimization task can be automatically completed without depending on other device terminals, so that the flow can be simplified, the time consumed by information conversion and transmission is reduced, the cost and the time of actual test are also reduced, and the optimization efficiency of the visual perception algorithm can be greatly improved.
According to the visual perception algorithm optimization method provided by the invention, the visual perception algorithm is verified and iterated based on the real data, the simulation data and the vehicle state simulation information, and the visual perception algorithm is updated on the basis of evaluation, so that the optimization of the visual perception algorithm is realized, the efficiency of a simulation verification process is improved, the effect of a verification result can be fully exerted, the accuracy and the optimization updating efficiency of the visual perception algorithm are improved, and the automatic driving is promoted to be safer and more efficient.

It can be understood that the fine-tune is a fine tuning training mode in the deep learning technology, where real data and simulation data may be called to perform fine tuning training on the visual perception algorithm, parameters of the updated visual perception algorithm may be adjusted, and the updated visual perception algorithm may be obtained according to the parameters of the updated visual perception algorithm.
In some embodiments, the step 110 of obtaining real data and simulation data further comprises:
acquiring original real data and original simulation data; and carrying out format correction processing on the original real data and the original simulation data to obtain the real data and the simulation data.
It will be appreciated that the simulation platform may include a data pre-processing unit that may format correct the raw real data and the raw simulation data, such as to perform a uniform format store, such as CV: mat, Image and other operations, width and height alignment operations, Image data correction, data frame number recording, and real data and simulation data can be obtained after the preprocessing operation.
In some embodiments, step 110, obtaining real data and simulation data, comprises: collecting real data and generating initial data; and performing error adjustment on the initial data based on the physical parameters of the camera to obtain simulation data.
It is understood that the data generating unit may generate initial data, which may have errors, and thus the initial data may be corrected, i.e., error-adjusted, in the error correcting unit using the real data and the physical parameters of the camera. The physical parameters of the camera can influence the imaging effect, the physical parameters of the camera are used for correcting initial data, the initial data are subjected to error adjustment, simulation data are obtained, and the simulation data are closer to an environment image under a real condition.
In some embodiments, the physical parameters include: at least one of sensor internal parameter, sensor external parameter, distortion coefficient, installation height, installation angle and installation gradient.
It is understood that the sensor physical parameters of the camera may include sensor internal parameters, sensor external parameters, distortion coefficients, mounting height, mounting angle and mounting inclination. These physical parameters can be used to make error adjustment on the initial data to obtain simulation data.
It is worth noting that the prior art lacks a sensor model building process, parameter comparison and error analysis between initial data and real data which are generated virtually, if the process is not available, the actual validity of the generated simulation data cannot be guaranteed, and the actual effect on the verification and optimization process of the visual perception algorithm is difficult to achieve.
The sensor internal parameters, the sensor external parameters, the distortion coefficient, the installation height, the installation angle and the installation inclination of the camera are introduced into the embodiment, the sensor physical parameters are used for carrying out error adjustment on the initial data, simulation data under different scenes can be simulated, simulation data under different working conditions close to the actual scene are generated, the simulation data are closer to actual video data in the actual scene, the reality of the simulation data for detection is higher, and the accuracy of obtaining a visual perception algorithm based on the simulation data for detection and optimization is also higher.
In some embodiments, the visual perception algorithm comprises at least: an obstacle detection algorithm and a lane line detection algorithm.
As shown in fig. 5, the invention can implement simultaneous verification and iteration on a plurality of visual perception algorithms, so that each visual perception algorithm corresponds to a Type identifier Type, and when the Type is 0, corresponds to an obstacle detection algorithm, and when the Type is 1, corresponds to a lane line detection algorithm.
It is understood that the obstacle detection algorithm can be used to extract obstacle information from the environment image of the vehicle, and the lane line detection algorithm can be used to extract lane line information from the environment image of the vehicle, although the visual perception algorithm may also include other related detection algorithms.
In some embodiments, the vehicle state simulation information includes chassis information, positioning information, and control information.
It can be understood that the vehicle state simulation information is state information simulating a vehicle in a real driving situation, and when the vehicle is in the real driving situation, the vehicle state information may include chassis information, positioning information and control information, the chassis information is used for reflecting forward, backward and steering information of a chassis of the vehicle, the positioning information is used for reflecting a real-time position of the vehicle, and the control information is used for reflecting a deceleration state, an acceleration state or a braking state of the vehicle.
In some embodiments, the visual perception algorithm optimization method is executed by the simulation test platform, that is, the visual perception algorithm optimization method can be automatically run by the simulation test platform without the need of other devices for assisting detection, the simulation test platform can automatically complete detection and optimization updating of the visual perception algorithm, time consumed by information conversion and transmission is reduced, and cost and time of actual test are also reduced, so that efficiency can be improved, and safety performance of automatic driving is further improved.
