[0039] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0040] To address the issues of missing charging station internal information in the global charging station map, which hinders vehicle navigation within the charging station, and the inaccuracy of existing charging station internal information, this invention provides a charging station map synchronization method for vehicles, such as... Figure 1 As shown, the method includes:
[0041] S110. Obtain the IMU data of the target moving vehicle within the charging station;
[0042] For example, the aforementioned target moving vehicle can be a manned vehicle, an unmanned vehicle, or a mobile robot, and is not limited thereto. The aforementioned IMU data can refer to test data obtained by the inertial measurement unit, typically a combination unit consisting of three accelerometers and three gyroscopes, mounted on mutually perpendicular measurement axes. Furthermore, most target moving vehicles possess an inertial measurement unit to monitor the vehicle's movement state in order to control the vehicle based on its movement.
[0043] S120. Determine the three-dimensional feature road surface information within the charging station based on the IMU data of the target moving vehicle;
[0044] For example, the aforementioned three-dimensional road surface information can be raised or recessed road markings or three-dimensional road surface features that serve a safety auxiliary function. Manually collecting and updating the global map of a charging station is often inefficient and difficult to achieve accuracy. Using image acquisition and analysis methods is prone to inaccuracies due to factors such as shooting angle, field of view, or ambient lighting, or the resulting image data may not provide satisfactory analysis, leading to poor reliability in determining the three-dimensional road surface information.
[0045] S130. Acquire panoramic image data of the surrounding area of the target moving vehicle collected by the vehicle-mounted image acquisition device of the target moving vehicle in the charging station.
[0046] For example, the panoramic image data mentioned above may include some non-road surface plan marking information or road surface plan marking information.
[0047] S140. Obtain planar signage information within the charging station based on the panoramic image data;
[0048] S150. Synchronize the planar identification information and the three-dimensional feature road surface information to the pre-stored global map of the charging station.
[0049] For example, the planar signage information and the three-dimensional road surface information can be directly synchronized to the pre-stored global map of the charging station. Alternatively, the planar signage information can be further verified by combining it with IMU data, and the verified planar signage information and the three-dimensional road surface information can be directly synchronized to the pre-stored global map of the charging station.
[0050] By employing the above technical solution, the charging station map synchronization method provided by this invention acquires IMU data of a target moving vehicle within the charging station; determines 3D feature road surface information within the charging station based on the IMU data of the target moving vehicle; acquires panoramic image data of the surrounding area of the target moving vehicle collected by the vehicle-mounted image acquisition device within the charging station; acquires planar marker information within the charging station based on the panoramic image data; and synchronizes the planar marker information and the 3D feature road surface information to a pre-stored global map of the charging station. Thus, by utilizing the target moving vehicle's own IMU sensor and monitoring the IMU data of the vehicle's movement within the charging station, the 3D feature road surface information within the charging station can be determined when the changes in the IMU data meet certain specific change characteristics. On the one hand, this addresses the problem that in some cases, image acquisition devices may acquire inaccurate image data, or the image analysis based on the image data may not achieve good analytical results, leading to poor reliability in determining 3D feature road surface information. On the other hand, it can obtain highly reliable 3D feature road surface information within the charging station without adding other hardware.
[0051] In one embodiment, determining the three-dimensional feature road surface information within the charging station based on the IMU data of the target mobile vehicle includes:
[0052] If the IMU data indicates that the target moving vehicle has two consecutive first jumps within a preset time interval, the speed bump information and the current position of the target moving vehicle are recorded.
[0053] For example, the aforementioned preset time interval can be set based on the common front-to-rear wheel spacing of vehicles. For instance, in charging stations for small and medium-sized vehicles, the preset time interval can be set based on the vehicle's speed when passing over a speed bump and the front-to-rear wheel spacing of the vehicle; for example, the preset time interval could be set to within 3 seconds. Then, if the IMU data indicates that the target moving vehicle has two consecutive first transitions within the preset time interval, combined with the possible road conditions and vehicle driving state within the charging station, it can be inferred that the vehicle's front and rear wheels passed over the speed bump sequentially. The speed bump information and the current position of the target moving vehicle can then be recorded, thus predicting the specific location of the speed bump within the charging station.
[0054] In one embodiment, determining the three-dimensional feature road surface information within the charging station based on the angular velocity data and acceleration data includes:
[0055] When the IMU data indicates that the target moving vehicle has multiple consecutive second jumps within a preset time interval, the anti-skid strip information and the current position of the target moving vehicle are recorded, wherein the amplitude of the first jump is greater than the amplitude of the second jump.
[0056] For example, the aforementioned anti-skid strip can be a dotted anti-skid strip or an anti-skid strip composed of continuous raised and recessed steps. Therefore, if the target moving vehicle experiences multiple consecutive second transitions within a preset time interval, it can be presumed that the vehicle's wheels have traversed a surface with continuous raised and recessed sections. Combining this with the possible road conditions within the charging station and the vehicle's possible driving state, it can be presumed that the vehicle has currently passed the anti-skid strip. The anti-skid strip information and the current position of the target moving vehicle can then be recorded, thus predicting the specific location of the anti-skid strip within the charging station.
[0057] In one embodiment, determining the three-dimensional feature road surface information within the charging station based on the angular velocity data and acceleration data includes:
[0058] When the IMU data indicates that the target moving vehicle is on a slope and there are multiple consecutive second jumps within a preset time interval, the anti-skid strip information and the current position of the target moving vehicle are recorded, wherein the amplitude of the first jump is greater than the amplitude of the second jump.
[0059] For example, when the IMU data indicates that the target moving vehicle is on a slope and there are multiple consecutive second transitions within a preset time interval, it can not only indicate that the vehicle's wheels have passed through a continuous series of bumps and depressions in the road surface, but also, since anti-skid strips are usually installed on steep slopes, when the IMU data indicates that the target moving vehicle is on a slope, combined with the possible road conditions within the charging station and the vehicle's possible driving state, it can be further inferred that the vehicle has currently passed through an anti-skid strip. This makes the prediction of three-dimensional road surface information more accurate.
[0060] In one embodiment, obtaining planar marker information within the charging station based on the panoramic image data includes:
[0061] Based on the panoramic image data, planar signage information within the charging station is obtained through a semantic segmentation model.
[0062] For example, a semantic segmentation model can be used to eliminate interference from pedestrians or vehicles in panoramic image data, filtering out planar signage information within the charging station. Furthermore, since the aforementioned semantic segmentation model considers not only grayscale and texture information, the output results are more accurate.
[0063] In one embodiment, obtaining planar marker information within the charging station based on the panoramic image data includes:
[0064] Based on the panoramic image data and the external parameters of the vehicle-mounted image acquisition device, the panoramic image data is converted into top-down view image data to obtain planar marking information within the charging station.
[0065] For example, effective data containing planar labeling information can be obtained by converting panoramic image data into top-down view image data.
[0066] In one embodiment, the above method further includes:
[0067] Obtain the relative position information of the planar marking information and the vehicle;
[0068] Based on the relative position information and the vehicle's position in the pre-stored global map, the position of the planar identification information in the pre-stored global map is calculated.
[0069] For example, since the above-mentioned planar marking information is obtained by capturing images with an in-vehicle image acquisition device, the vehicle is often not located at the location of the planar marking information when the image containing the planar marking information is acquired. Therefore, the relative position information between the planar marking information and the vehicle can be obtained. Based on the relative position information and the position of the vehicle in the pre-stored global map, the position of the planar marking information in the pre-stored global map is calculated.
[0070] Furthermore, as a response to the above Figure 1 In addition to the implementation of the method shown, this embodiment of the invention also provides a charging station map synchronization device for the above-mentioned... Figure 1 The method shown is implemented accordingly. This device embodiment corresponds to the foregoing method embodiment. For ease of reading, this device embodiment will not repeat the details of the foregoing method embodiment, but it should be clear that the device in this embodiment can implement all the contents of the foregoing method embodiment. Figure 2 As shown, the device includes: a first acquisition unit 210, a first determination unit 220, a second acquisition unit 230, a second determination unit 240, and a synchronization unit 250, wherein...
[0071] The first acquisition unit 210 is used to acquire IMU data of the target moving vehicle within the charging station;
[0072] The first determining unit 220 is used to determine the three-dimensional feature road surface information within the charging station based on the IMU data of the target moving vehicle;
[0073] The second acquisition unit 230 is used to acquire panoramic image data of the surrounding area of the target moving vehicle collected by the vehicle-mounted image acquisition device of the target moving vehicle in the charging station.
[0074] The second determining unit 240 is used to obtain planar marking information within the charging station based on the panoramic image data;
[0075] The synchronization unit 250 is used to synchronize the planar identification information and the three-dimensional feature road surface information to the pre-stored global map of the charging station.
[0076] By employing the above technical solution, the charging station map synchronization device provided by this invention acquires IMU data of a target moving vehicle within the charging station; determines 3D feature road surface information within the charging station based on the IMU data of the target moving vehicle; acquires panoramic image data of the surrounding area of the target moving vehicle collected by the vehicle-mounted image acquisition device within the charging station; acquires planar marker information within the charging station based on the panoramic image data; and synchronizes the planar marker information and the 3D feature road surface information to a pre-stored global map of the charging station. Thus, by utilizing the target moving vehicle's own IMU sensor and monitoring the IMU data of the vehicle's movement within the charging station, the 3D feature road surface information within the charging station can be determined when the changes in the IMU data meet certain specific change characteristics. On the one hand, this addresses the problem that image acquisition devices sometimes acquire inaccurate image data, or that image analysis based on the image data does not achieve good analytical results, leading to poor reliability in determining 3D feature road surface information. On the other hand, it can obtain highly reliable 3D feature road surface information within the charging station without adding other hardware.
[0077] The processor contains a kernel, which retrieves the corresponding program units from memory. One or more kernels can be configured, and by adjusting kernel parameters, a method for synchronizing charging station maps can be implemented. This method addresses the issues of missing on-site information for charging stations in the global map, hindering vehicle navigation within charging stations, and the inaccuracy of existing on-site information for charging stations.
