Abstract
Description
Technical Field
[0001] This utility model relates to the field of autonomous driving environmental perception technology, and in particular to a binocular stereo vision surround view system integrated with a shark fin on the roof. Background Technology
[0002] Intelligent surround view systems for cars are becoming increasingly diverse. By monitoring the surroundings of the vehicle in real time and feeding the monitoring information back to the driver's cab, drivers can make advance predictions based on the information fed back by the driving monitoring equipment, so as to control the vehicle.
[0003] Traditional surround view systems require multiple monocular cameras to be installed around the vehicle body. This not only results in complex wiring and affects the aesthetics, but also requires independent calibration and synchronous processing for multiple camera systems, leading to high hardware and computing costs. In addition, current solutions that integrate monocular cameras into the shark fin antenna support 2D surround view but lack depth information; there are also multi-camera arrays on the roof, but this results in a bulky overall structure and requires additional protection.
[0004] To address these issues, a binocular stereoscopic vision surround view system integrated with a car roof shark fin is designed. Utility Model Content
[0005] In view of the above-mentioned technical problems, this utility model provides a roof-mounted shark fin integrated binocular stereoscopic vision surround view system. The overall structure is compact, reduces wind resistance, increases the camera range, enhances stereoscopic vision, simplifies the installation process, and improves the vehicle's aesthetics.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] A car roof-mounted shark fin integrated binocular stereoscopic vision surround view system includes a bottom shell and a shark fin shell. The bottom opening of the shark fin shell connects to the bottom shell. The system is characterized by a binocular support frame housed within the cavity formed by the shark fin shell and the bottom shell. An adjustable angle assembly connects the binocular support frame to a binocular camera. Heating wires are arranged inside the shark fin shell.
[0008] The binocular support is configured with a concave structure.
[0009] The adjustable angle assembly consists of a rotating shaft and a positioning locking screw. Rotating shafts are respectively provided on both side walls of the binocular camera. The other end of each rotating shaft is mounted on the binocular bracket via a bearing. Both ends of the binocular bracket are provided with arc-shaped grooves, and positioning locking screws are installed within these grooves. The front end of each positioning locking screw is connected to a threaded hole provided on the side wall of the binocular camera.
[0010] The shark fin shell has air vents on the front and rear sides of its upper end. Waterproof and breathable membranes are installed at the two air vents by heat welding. The two air vents form an airflow channel when the vehicle is in motion, thereby dissipating heat from the inside of the shell.
[0011] Furthermore, a viewing window is installed at the viewing port on the front side of the shark fin shell, and a waterproof adhesive is provided between the viewing window and the shark fin shell to improve the sealing performance.
[0012] Furthermore, a waterproof adhesive is provided at the connection between the shark fin shell and the bottom shell to ensure that the inside of the shark fin is a waterproof and sealed structure.
[0013] Furthermore, the shark fin shell is made of a lightweight, high-strength composite material, such as carbon fiber reinforced plastic.
[0014] The beneficial effects of this utility model are:
[0015] This utility model achieves a compact integrated design. By installing a binocular camera inside the shark fin shell on the roof, it achieves a layout that shares the shell with communication equipment that should be installed in the shark fin shell, thereby reducing the number of exposed devices on the roof and avoiding the damage to the vehicle body design caused by traditional external cameras. Moreover, the binocular camera increases the field of view and improves stereo vision compared to the traditional monocular camera.
[0016] This utility model mounts a binocular camera on a double-sided bracket using an adjustable angle assembly. The tilt angle of the binocular camera can be finely adjusted by operating the positioning and locking screws, thus meeting more usage needs and enhancing practicality.
[0017] This invention provides airflow ports on the front and rear sides of the upper end of the shark fin shell, and installs a waterproof and breathable membrane at the airflow ports by hot welding, so that an airflow channel is formed between the two airflow ports when the vehicle is moving, making the shark fin shell waterproof and breathable as a whole, and efficiently dissipating heat.
[0018] This invention features a heating wire arranged inside the shark fin shell. When the lens of the binocular camera detects water vapor, the heating wire is activated to heat the water and remove the fog. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0026] Example 1
[0027] As shown in the figure, the bottom opening of the shark fin shell 1 is connected to the bottom shell 2, and a waterproof adhesive is provided at the connection between the shark fin shell 1 and the bottom shell 2. A viewing window 6 is installed at the viewing opening 12 on the front side of the shark fin shell 1, and a waterproof adhesive is provided between the viewing window 6 and the shark fin shell 1, thus making the interior of the shark fin shell 1 a waterproof and sealed structure.
[0028] In order to achieve waterproof and breathable heat dissipation of the shark fin shell 1, air vents 11 are provided on the front and rear sides of the upper end of the shark fin shell 1. The waterproof and breathable membrane 5 is installed at the two air vents 11 by heat welding. When the vehicle is moving, an airflow channel is formed between the two air vents 11, thereby dissipating heat to the inside of the shell.
[0029] like Figure 2 and 3 A binocular support 3 is provided in the inner cavity formed by the shark fin shell 1 and the bottom shell 2. The binocular support 3 is mounted on the bottom shell 2 and is designed with a concave structure. The binocular support 3 is connected to the binocular camera 4 through an adjustable angle component. The two side walls of the binocular camera 4 are respectively provided with a rotating shaft 7. The other end of the rotating shaft 7 is mounted on the binocular support 3 through a bearing. The two ends of the binocular support 3 are respectively provided with an arc groove 31 and a positioning locking screw 8 is provided in the arc groove 31. The front end of the positioning locking screw 8 is connected to the threaded hole provided on the side wall of the binocular camera 4. After the angle is adjusted, the positioning locking screw 8 will move towards the binocular camera 4 by tightening the positioning locking screw 8, so that the nut of the positioning locking screw 8 presses the binocular support 3, and the binocular support 3 will be in close contact with the side wall of the binocular camera 4 to complete the limiting of the binocular camera 4. Preferably, the surface of the binocular support can also be designed with a granular texture to achieve strong compression between the screw and the support surface.
[0030] Furthermore, to remove moisture that may accumulate on the camera lens, a heating wire is installed inside the shark fin shell 1. When the lens of the binocular camera 4 detects moisture, the controller in the vehicle's main control system activates the heating wire inside the shark fin shell 1 to heat it and defog it. It should be noted that the fog detection function of this binocular camera 4 is a built-in function of existing cameras; therefore, the principle behind its detection is not described in detail in this application.
[0031] Furthermore, the shark fin shell 1 is made of lightweight, high-strength composite material, and carbon fiber reinforced plastic can be used to improve its protective performance.
[0032] Example 2
[0033] This utility model achieves a layout that shares the same housing with some communication equipment that would otherwise be installed in the shark fin housing by installing a binocular camera 4 inside the shark fin housing 1 on the roof of the vehicle, thereby reducing the number of exposed devices on the roof and avoiding the damage to the vehicle body design caused by traditional external cameras.
[0034] The binocular camera 4 is embedded in the streamlined shark fin shell 1 to reduce wind noise and additional wind resistance at high speeds, and avoid the impact of traditional external cameras (such as rearview mirror mounting) on the vehicle's aerodynamic performance.
[0035] In addition, the use of binocular camera 4 increases the field of view compared to the traditional monocular camera. Moreover, binocular camera 4 uses binocular parallax to calculate scene depth, fuses multi-view data to generate 3D point cloud, and outputs obstacle position, distance and motion trajectory, thereby improving stereo vision.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
