[0002] Autonomous vehicles (also known as driverless cars, computer-driven cars, or wheeled mobile robots) are intelligent vehicles that achieve driverless operation through computer systems. They have existed for decades in the 20th century and showed a trend towards practical application in the early 21st century. Autonomous vehicles rely on the collaborative efforts of artificial intelligence, computer vision, radar, monitoring devices, and GPS to enable computers to operate motor vehicles safely and automatically without any human intervention. The environmental perception system is crucial for ensuring the safe and autonomous driving of autonomous vehicles. This system integrates various advanced sensor technologies and data processing methods to acquire real-time and accurate information about the vehicle's surroundings. Specifically, the environmental perception system uses multiple sensors, such as LiDAR, cameras, and millimeter-wave radar, to perform comprehensive and high-precision monitoring and identification of roads, pedestrians, other vehicles, traffic signs, and obstacles around the vehicle. Existing autonomous vehicles use their forward-facing cameras to collect data during path planning. However, forward-facing cameras are typically mounted with multiple bolts, which makes installation inconvenient and disassembly difficult during subsequent maintenance. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-4This utility model provides the following technical solution: a path planning auxiliary device for autonomous vehicles, including a high-definition camera body 1, a side ring 2 connected to the surface of the high-definition camera body 1, an adjustment groove 3 formed on the inner wall surface of the side ring 2, an adjustment block 4 fitted into the surface of the adjustment groove 3, the surface of the adjustment block 4 connected to the surface of the connecting block 5, the top surface of the connecting block 5 connected to the bottom of a first side frame 6, a positioning plate 7 connected to the transverse end surface of the first side frame 6, the surface of the positioning plate 7 fitted into the surface of a positioning groove 8, the positioning groove 8 formed on the transverse section surface of a second side frame 9, the surface of the second side frame 9 movably abutting against the surface of the first side frame 6, and the connecting block 5 connected to the bottom surface of the second side frame 9. The top surface of the first side frame 6 and the second side frame 9 is connected to the top frame 10. The surface of the top frame 10 is fitted into the surface of the limiting groove 11. The limiting groove 11 is opened at the bottom of the mounting base 12. The surface of the mounting base 12 is connected to the side rod 13. The surface of the side rod 13 is inserted into the circular groove 15 opened on the surface of the rubber strip 14. The surface of the rubber strip 14 is bonded with a rubber block 16. In this design scheme, the high-definition camera body 1 is the main body of the car-mounted front-view camera. The main body of the car-mounted front-view camera contains a large number of related components. Since these are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution. The main model of the automotive front-view camera in this solution is the 8MPOVOX08B40 series.

[0015] In use: The automotive front-view camera is based on an automotive-grade back-illuminated CMOS sensor. It uses multiple aspherical optical lenses to collect light signals from the environment in front of the vehicle and converts them into 8.3-megapixel RAW format images. Then, the built-in ISP chip performs real-time processing on the images, such as HDR synthesis, noise reduction, and LED flicker reduction, and outputs clear YUV format visual data. The data is then transmitted to the autonomous driving domain controller via the GMSL2 high-speed serial interface. The perception algorithm in the controller identifies targets such as lane lines, traffic signs, vehicles, or pedestrians in the image and constructs an environmental semantic model that includes road topology, obstacle locations, and traffic rules. Finally, this model, combined with high-precision maps and real-time positioning information, provides road constraints for global path planning and provides decision-making basis for dynamic obstacle avoidance and lane keeping for local trajectory planning, realizing closed-loop support from environmental perception to path optimization.

[0016] Preferably, the adjusting groove 3 is a rectangular through groove, the shape and size of which are adapted to the adjusting block 4, and the adjusting groove 3 is distributed in a ring at equal intervals on the inner wall of the side ring 2.

[0017] In practical use, the connecting blocks 5 connecting the bottom of the first side frame 6 and the second side frame 9 are inserted into the side ring 2 respectively. At the same time as insertion, the four adjusting blocks 4 distributed in a ring are inserted into the adjusting slots 3 at different positions, thereby adjusting the position of the high-definition camera body 1 on the first side frame 6 and the second side frame 9.

[0018] Preferably, the positioning groove 8 is a rectangular groove, the shape and size of which are adapted to the positioning plate 7.

[0019] In practical use, while the first side frame 6 and the second side frame 9 are docking, the positioning plate 7 connected to the top of the first side frame 6 abuts against the positioning groove 8 opened on the surface of the second side frame 9, thereby guiding and limiting the docking of the first side frame 6 and the second side frame 9.

[0020] Preferably, both the first side frame 6 and the second side frame 9 are "L" shaped integrated structures.

[0021] In practical use, the first side frame 6 and the second side frame 9 are connected together to fix the position of the high-definition camera body 1. At the same time, the symmetrical distribution structure makes the connection between the two more stable.

[0022] Preferably, the surface of the rubber block 16 is fitted and connected to the surface of the limiting groove 11, and the surface of the rubber block 16 abuts against the surface of the top frame 10.

[0023] In practical use, the rubber block 16 is used to abut against the surface of the top frame 10, and then the circular through grooves opened on both sides of the surface of the rubber strip 14 are fitted onto the side rods 13 on both sides of the mounting base 12, thereby fixing the position of the side rods 13 on one side of the mounting base 12.

[0024] Preferably, the top frame 10 is an L-shaped integrated structure, and two top frames 10 are mirror-connected to form a T-shaped structure, the shape and size of which are adapted to the limiting groove 11, and the shape and size of the limiting groove 11 are adapted to the rubber block 16.

[0025] In practical use, the top frame 10, which is connected to the top of the first side frame 6 and the second side frame 9, abuts together at its longitudinal end to form a "T" shape. At this time, the top frame 10 can be fitted into the limiting groove 11.

[0026] Working principle: When using the high-definition camera body 1 to assist in the path planning of autonomous vehicles, the 3MVHB adhesive on the top of the mounting base 12 is glued to the windshield of the car, which facilitates the fixation of the mounting base 12 in the position inside the car. Alternatively, the mounting base 12 can be welded or fixed to the frame inside the car using the mounting holes on both sides of the top of the mounting base 12. Then, according to the car model and actual use needs, the connecting blocks 5 connected to the bottom of the first side frame 6 and the second side frame 9 are inserted into the side ring 2 respectively. At the same time as insertion, the four ring-shaped adjustment blocks 4 are inserted into the adjustment slots 3 at different positions, thereby adjusting the position of the high-definition camera body 1 on the first side frame 6 and the second side frame 9. The ring-shaped adjustment slots 3 in the side ring 2 can be adjusted by 1° for each slot, thereby adapting to the slope of the windshield of various car models, thus ensuring that the field of view of the high-definition camera body 1 covers key targets such as lane lines, distant vehicles, and traffic signs. While the first side frame 6 and the second side frame 9 are docking, the positioning plate 7 connected to the top of the first side frame 6 abuts against the positioning groove 8 opened on the surface of the second side frame 9, thereby guiding and limiting the docking of the first side frame 6 and the second side frame 9. After the first side frame 6 and the second side frame 9 are initially docked, the connecting blocks 5 symmetrically distributed at the bottom can be inserted into the side rings 2 on both sides of the high-definition camera body 1 respectively. When the positioning plate 7 is fully inserted into the positioning groove 8, the horizontal ends of the top of the first side frame 6 and the second side frame 9 abut together, and the vertical ends of the top frame 10 connected to the top of the first side frame 6 and the second side frame 9 abut together, forming a "T" shape. At this time, the top frame 10 can be fitted into the limiting groove 11, thereby fixing the position of the high-definition camera body 1 at the bottom of the mounting base 12. Then, the rubber block 16 abuts against the surface of the top frame 10. Then, the circular through grooves opened on both sides of the surface of the rubber strip 14 are sleeved on the side rods 13 on both sides of the mounting base 12, thereby fixing the position of the side rods 13 on one side of the mounting base 12, and thus stabilizing and fixing the position of the high-definition camera body 1 at the bottom of the mounting base 12. Both sides of the rubber strip 14 and the entire rubber block 16 are made of silicone rubber, which is elastic and can absorb and buffer the impact and vibration.
