The scene construction subsystem is used for processing the scene files in the corresponding scene to further obtain the corresponding simulation scene. If the user wants to construct a simulation scene corresponding to the area a, the area a may be used as a target area. The simulation scene file may be a scene file corresponding to the target area. The scene file may include therein element information of various traffic elements in the environment. The data to be processed corresponds to traffic element information in the target area, and the traffic element information includes information such as pedestrians, vehicles, and indicator lights. The target area is an area without the drive test. The simulation service subsystem loads a simulation file to obtain a corresponding dynamic scene, namely the dynamic scene can be subjected to corresponding simulation processing.
For example, referring to FIG. 2, an autopilot simulation system includes a scene building subsystem and a simulation service subsystem. And the scene construction subsystem is used for processing the received data to be processed to obtain a simulation scene file corresponding to the target area. The simulation service subsystem is used for processing the simulation scene file to obtain a dynamic simulation scene. And processing the subsystem to be tested based on the dynamic simulation scene to further obtain a corresponding test report.
Wherein, an automatic driving algorithm is integrated in the subsystem to be tested. The tested subsystem can receive the traffic element state information sent by the simulation service subsystem, and enters a vehicle control instruction for sending a driving algorithm, namely, the vehicle is controlled to run in a simulation test scene based on an automatic driving algorithm.
In this embodiment, before the scene-based construction subsystem processes the received data to be processed, the data acquisition system is further required to acquire the corresponding data to be processed.
The data acquisition subsystem can be arranged on a corresponding vehicle, and the vehicle can be an unmanned vehicle or a driveable vehicle. The automatic driving complete set of hardware and software can be loaded on the vehicle to support sensing data acquisition and automatic driving functions. The hardware may be a camera and a lidar. The vehicle can run in each area, and in the running process, the traffic element information in the corresponding area is collected based on the camera device and the laser radar, namely the traffic flow data is collected in real time. After the collection is completed, the collected data can be stored locally, and the data stored locally is stored in a preset format, wherein the preset format can be record.
Specifically, in the vehicle driving process, the actual traffic flow information may be acquired based on a data acquisition subsystem provided on the vehicle, and the actual traffic flow information may be stored locally as the data to be processed according to a preset format. That is, the data collection subsystem is used for collecting real traffic element data in a real traffic environment, such as information of each vehicle, pedestrian, indicator light, road condition and the like in the real traffic environment.
In this embodiment, the data acquisition subsystem includes a camera module and a data conversion module. And the camera module is used for shooting image information in the target area when the unmanned vehicle is controlled to run or other vehicles driven by people run. The target area may be an area corresponding to a scene to be tested, for example, if traffic element information in the area a is to be collected, the area a may be used as the target area. The target image information includes traffic element information including at least one of roads, pedestrians, vehicles, and indicator lights in the target area. And the data conversion module is communicated with the camera module and is used for converting the target image into structured data after the camera module collects the target image information, so as to obtain a light data stream corresponding to the target area, namely, the light data stream corresponding to the video stream. The lightweight data stream may be treated as data to be processed.
It should be noted that after the to-be-processed data is obtained, the to-be-processed data can be stored to the local, and when the to-be-processed data is stored locally, the to-be-processed data can be stored according to a preset format.

Based on the fitting module, the traffic element information can be fused in the map to obtain a dynamic simulation scene. That is to say, the data acquired by the data acquisition module is static data, and in order to obtain a simulation scene, the static data and a map of a certain area may be fused to obtain a dynamic scene file. The dynamic scene file may be used as a simulation scene file.

In this embodiment, the simulation service subsystem is configured to analyze the simulation scene file to convert the simulation scene file into a dynamic scene; and the dynamic scene is matched with a scene corresponding to the unmanned vehicle when the unmanned vehicle runs in the target area.
The dynamic scene can be understood as a simulated scene of a real environment. That is, the dynamic scene matches a scene corresponding to the unmanned vehicle when traveling in the target area.
In this embodiment, the simulation service subsystem includes: the state updating module is used for creating an information sending sub-thread and sending updated traffic element information to the tested subsystem according to a preset configuration rule; the monitoring module is used for monitoring the vehicle control instruction fed back by the tested subsystem based on the updated traffic element information; and the control module is used for receiving the vehicle control instruction and controlling simulation to run in the dynamic scene based on the vehicle control instruction.
The state updating module is mainly used for creating sub-threads and continuously updating the states of the traffic elements, such as the position information of each traffic element in a map. Meanwhile, the state updating module is also used for periodically sending the latest state information of the traffic elements to the subsystem to be tested. After receiving the updated traffic element state information, the tested subsystem can send a corresponding control instruction to the target vehicle based on an automatic driving algorithm. At this time, the monitoring module can monitor the vehicle control command fed back by the subsystem to be tested.
It should be noted that the vehicle control command fed back by the tested subsystem is generated by the automatic driving algorithm based on the updated traffic element state information. If yes, the updated traffic element status information is: and when the tested subsystem determines that the distance between the two pieces of position information is smaller than a preset distance threshold value, the sent central control instruction can be that the target simulation vehicle stops running or the target simulation vehicle decelerates to run. And the control module can control the target simulation vehicle to execute the operation corresponding to the central control instruction based on the received central control instruction. At this time, the corresponding operation may be the movement of the control target simulation vehicle in the simulation map, and the simulation process of the above operation continues until the simulation is finished or abnormally terminated.
According to the technical scheme of the embodiment of the invention, the received data to be processed corresponding to the target area is processed through the scene construction subsystem to obtain the simulation scene file corresponding to the target area, the simulation service subsystem obtains the simulation scene file determined by the scene construction subsystem and processes the simulation scene file to obtain the dynamic scene corresponding to the target area, so that the tested subsystem is subjected to automatic driving simulation based on the dynamic scene, at the moment, the automatic driving algorithm is integrated in the tested subsystem, the technical problems of low safety and high cost due to the fact that the road test is required when the automatic driving algorithm of the unmanned vehicle is tested in the prior art are solved, the automatic driving algorithm is tested in the virtual scene, and the virtual scene is constructed based on the actually acquired road environment information, so that the reality of the simulation test is improved, Safety and effectiveness.
