[0057] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0058] In the related art, the configuration files of the autonomous driving simulation scene are usually saved in a specific format, such as XML, JSON or YAML. These configuration files contain various parameters and properties of the scene, such as road layout, vehicle model, sensor configuration, etc. To render and display the configuration files of the autonomous driving simulation scene, corresponding simulation software or tools can be used. These simulation software or tools usually provide a visual interface that can load and parse the configuration files and render the scene into a graphical scene model.
[0059] However, the following technical problems exist in the current simulation scene construction:
[0060] The current simulation scenario construction relies on specific simulation software or tools, which leads to limitations in the application of technicians and poor flexibility in scenario construction.
[0061] Based on this, a method for constructing a simulation scene in a target environment provided by an embodiment of the present application can be applied to an application environment as shown in Figure 1. Among them, the terminal 102 communicates with the background server 104 through a network. The data storage system can store the data that the background server 104 needs to process. The data storage system can be integrated on the background server 104, or it can be placed on the cloud or other network servers. Specifically, the terminal 102 can send a preview request of the simulation scene to the background server 104, and the background server 104 can respond to a specific file to the terminal 102 according to the received preview request, so that the terminal 102 completes the construction of the simulation scene. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices, and the Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented with an independent server or a server cluster consisting of multiple servers.
[0062] In one embodiment, Figure 2 As shown, a method for constructing a simulation scene in a target environment is provided, and the method is applied to the terminal in FIG1 as an example for explanation, including the following steps:
[0063] Step 202: In response to a user's request to preview a simulation scene, a scene construction file of the simulation scene to be constructed is obtained.
[0064] The scenario construction file may refer to a file used to describe the configuration content of the simulation scenario, and may be a file that complies with the opendrive standard, such as an xodr file.
[0065] Exemplarily, the terminal may obtain a preview request from a user for a simulation scene, and send demand information for building a simulation request to a background server according to the preview request, thereby obtaining a scene building file corresponding to the simulation scene to be built fed back by the background server.
[0066] Step 204: Obtain a target parsing function library for parsing the scenario construction file, and compile the target parsing function library into a lightweight parsing program adapted to the target environment.
[0067] Among them, the target parsing function library may refer to a function library used to convert a file in a specific format to another format so as to read the information in the file. The target parsing function library may be tinyXML2, etc. Specifically, tinyXML2 refers to a small XML parser that can convert xodr files into object objects in the application for subsequent visualization of threejs content. Compilation may refer to a process for converting a specific code from source code (such as a high-level language) to target code (such as machine code). A lightweight parser may refer to an application program that has the same functions as the target parsing function library but is supported in a specific code form. In this embodiment, based on the need to adapt to the operation in the target environment, a lightweight parser may refer to a small code-scale program adapted to the target environment, such as the wasm program.
[0068] Exemplarily, after obtaining the scene construction file, the terminal can obtain a target parsing function library that can parse the scene construction file. Taking the scene construction file in this embodiment as an xodr file as an example, the tinyXML2 function library can be compiled into a wasm program, that is, a lightweight parsing program, through the WebAssembly compiler tool chain.
[0069] Step 206: Apply the lightweight parser in the target environment to parse the scenario construction file to obtain scenario parameters of the simulation scenario.
[0070] Among them, scene parameters can refer to parameters used to describe static scene information in the simulation scene, such as road width, number of lanes, lane line type, road signs, lane direction, central isolation zone type, road surface flatness and other scene information.
[0071] Exemplarily, the terminal may apply the compiled lightweight parsing program to parse the scene construction file to obtain the scene parameters of the simulation scene.
[0072] Step 208: Construct the simulation scenario in the target environment based on the scenario parameters.
[0073] Exemplarily, the terminal may construct a simulation scenario in a target environment according to the scenario parameters, and the target environment may refer to a web environment.
[0074] In the above-mentioned method for constructing a simulation scene in a target environment, reasonable deduction is performed in combination with the technical features in the embodiment, which can achieve the following beneficial effects of solving the technical problems raised in the background technology:
[0075] When configuring the simulation scene, firstly, according to the user's preview request for the simulation scene, the scene construction file of the simulation scene is obtained. At this time, the scene construction file is in a readable state by the simulation software. In order to run in the target environment, the target parsing function library for parsing the scene construction file can be obtained, and the target parsing function library can be compiled into a lightweight parsing program, so that the scene construction file is parsed by the lightweight parsing program to obtain the scene parameters, and finally the simulation scene is constructed in the target environment through the scene parameters. In implementation, by compiling the target parsing function library into a lightweight parsing program, it is helpful to parse the scene construction file in different target environments through the lightweight parsing program, so as to obtain the scene parameters for practical application and scene construction, replacing the solution that needs to use independent simulation software or tools to process the scene construction file, so that the scene construction file can be parsed and constructed in a specific environment, such as a web environment, which improves the flexibility of scene file parsing and previewing, and enhances the efficiency and accuracy of scene configuration.
[0076] In one embodiment, the Figure 3 As shown, step 202 includes:
[0077] Step 302: In response to a user's preview request for the simulation scenario, the preview request is sent to a target data platform, where the preview request includes a description file of the simulation scenario.
[0078] The preview request may refer to request data for describing a simulation scene requested by a user, and the preview request may include a description file corresponding to the simulation scene.
[0079] Exemplarily, the terminal may send a preview request to the target data platform in response to a user's request to preview the simulation scene.
[0080] Step 304: Obtain the scenario construction file responded by the target data platform, wherein the scenario construction file is obtained by the target data platform determining the scenario parameters according to the description file and then calling a preset generalization script to process the scenario parameters into a target format.
[0081] Among them, the generalized script can refer to a general script for processing data, which can process, convert and analyze different types of data according to specific needs.
[0082] For example, when the terminal requests a scene building file, the target data platform can read the scene parameters in the database and output the scene parameters in a specified format, such as a json file. Subsequently, the terminal can convert the json file into a xodr file through a python generalization script.
[0083] In this embodiment, generalizing the data responded by the background database helps to obtain a scene construction file in a unified format, thereby helping to improve the efficiency and accuracy of scene construction.
[0084] In one embodiment, Figure 4 As shown, step 206 includes:
[0085] Step 402: Read the scene construction file into the memory space of the target environment, and generate the scene parameters corresponding to the scene construction file.
[0086] Exemplarily, the terminal may read the scene construction file completely into the memory space of the target environment, thereby generating scene parameters that meet the requirements of the opendrivemap object.
[0087] Step 404: Obtain the file stream of the scene construction file, read the data block from the file stream, parse the data block, and obtain the scene parameter.
[0088] Exemplarily, the terminal may also process the scene construction file into a file stream, thereby reading data blocks from the file stream, parsing the data blocks, and obtaining scene parameters.
[0089] In this embodiment, the scene construction file can be parsed through a stream processing architecture, which helps to avoid the failure of scene construction file parsing due to memory space limitations of the target environment, thereby helping to improve the stability of scene construction file parsing.
[0090] In one embodiment, the Figure 5 As shown, step 404 includes:
[0091] Step 502: Obtain the memory space capacity of the target environment, and determine the reading speed of the data block according to the memory space capacity.
[0092] Exemplarily, during the stream processing, the terminal may obtain the memory space capacity of the target environment in advance, thereby determining the reading speed of the data block according to the memory space capacity.
[0093] In this embodiment, the reading speed of the data block is set according to the memory space capacity, which helps to reduce the possibility of content overflow, thereby improving the stability of data parsing.
[0094] In one embodiment, the Figure 6 As shown, step 208 includes:
[0095] Step 602: Obtain object properties of scene elements in the simulation scene based on the scene parameters.
[0096] The scene elements may refer to static objects existing in the simulation scene, such as roads, signboards, objects on the road surface, lane lines, etc.
[0097] Exemplarily, the terminal may read the scene parameters to extract object attributes of the scene elements therein, such as reflines attributes, road network attributes, roadmarks attributes, road objects attributes, lane outline attributes, and the like.
[0098] Step 604: Generate a target scene element according to the object attribute, and add the target scene element to the scene background.
[0099] Exemplarily, the terminal can generate target scene elements according to object properties and add the target scene elements to the scene background. Specifically, the reflines attribute can be read, the LineSegments module of threejs can be called to draw the scene reference lines, and then added to the scene; the road network attribute can be read, the geometry and mesh modules of threejs can be called to draw the road structure, and then added to the scene; the roadmarks attribute can be read, the geometry and mesh modules of threejs can be called to draw the road signs, and then added to the scene; the road objects attribute can be read, the geometry and mesh modules of threejs can be called to draw the objects on the road, and then added to the scene; the lane outline attribute can be read, the LineSegments module of threejs can be called to draw the lane lines, and then added to the scene. Finally, the construction of the simulation scene is completed.
[0100] In one embodiment, it can be Figure 7 As shown, after step 208, the following steps are also included:
[0101] Step 702: In response to the user's interactive operation in the target environment, the simulation scene is displayed and adjusted, wherein the display adjustment includes one or more of camera angle adjustment, light intensity adjustment, and scene size adjustment.
[0102] Exemplarily, the terminal may adjust the display parameters of the simulation scene in response to the user's interactive operation in the target environment, thereby achieving display adjustment in the page, and the display adjustment may include one or more of camera angle adjustment, light intensity adjustment, and scene size adjustment.
[0103] In this embodiment, the display adjustment process of the simulation scene can improve the flexibility of the simulation scene application.
[0104] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
