Abstract
Description
Technical Field
[0001] This utility model relates to the field of autonomous driving technology, and in particular to an integrated surround-view stereo vision system for automotive fenders based on a binocular all-in-one machine. Background Technology
[0002] Currently, autonomous vehicles mainly rely on monocular cameras, millimeter-wave radar, or lidar for environmental perception. However, monocular cameras lack depth information, while lidar is relatively expensive.
[0003] In addition, the surround view system currently used in autonomous vehicles generally uses four wide-angle cameras, which are installed in front, behind, left and right of the car, and then the images from the four directions are stitched together. However, this also has blind spots and cannot provide stereo vision information.
[0004] Current vehicles also use binocular cameras to improve stereo vision, but the installation location is usually on the roof or windshield, and the fixed installation position makes it difficult to cover the sides and rear of the vehicle, creating blind spots. To address this, we designed an integrated surround-view stereo vision system for automotive fenders based on a binocular all-in-one camera. Utility Model Content
[0005] In view of the above-mentioned technical problems, this utility model provides an integrated surround-view stereo vision system for automobile fenders based on binocular all-in-one machine, which is used to realize surround-view perception of the surrounding environment of the vehicle, thereby improving the environmental perception capability of the autonomous driving system.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] An integrated surround-view stereo vision system for automotive fenders based on a binocular all-in-one camera is characterized by comprising an embedded shell, a rear shell, a camera bracket, a binocular camera, heating wires, and shock-absorbing silicone pads. The embedded shell is adapted to an embedded groove on the fender and is installed within the groove. The embedded shell is connected to the rear shell, and the cavity formed by the connection of the embedded shell and the rear shell houses the camera bracket, which is mounted on the rear shell. The binocular camera is mounted on the camera bracket in an adjustable manner. A shock-absorbing silicone pad is provided between the camera bracket and the rear shell. Heating wires are arranged inside the embedded shell.
[0008] The binocular camera has connecting shafts at both ends, which are connected to the camera bracket. The camera bracket has guide grooves with limiting screws, and the front end of the limiting screws is threaded into threaded holes on the binocular camera.
[0009] Furthermore, the rear shell is provided with airflow holes, and the waterproof and breathable membrane is fixed at the airflow holes of the rear shell by heat welding, which is used to dissipate heat to the cavity formed by the embedded shell and the rear shell.
[0010] Furthermore, a temperature sensor is installed inside the cavity formed by the embedded shell and the rear shell to detect the temperature inside the cavity, thereby dynamically adjusting the heating power of the heating wire according to the ambient temperature to prevent the clarity of the lens from being affected in rainy or snowy weather.
[0011] Furthermore, a viewing port is provided on the front side of the embedded shell, and a waterproof viewing window cover is installed at the viewing port of the embedded shell.
[0012] Furthermore, a waterproof adhesive is provided at the connection between the embedded shell and the rear shell to improve the overall waterproof sealing performance.
[0013] Furthermore, mounting holes are provided on both sides of the rear shell for connecting the rear shell to the fender using screws.
[0014] Furthermore, the binocular camera uses a miniaturized camera module, such as a 1 / 2.5-inch CMOS sensor, with a total thickness of ≤30mm, thus adapting to the internal space of the fender.
[0015] The beneficial effects of this utility model are:
[0016] This utility model adopts an embedded installation in the inner groove of the fender to avoid protruding the body outline, thereby maintaining the integrity of the body design. The rear shell and the fender are installed in a detachable fixing method, realizing the detachability of the entire camera module, which can be quickly replaced, reducing maintenance costs and avoiding the need to replace the camera module when replacing the fender.
[0017] This utility model embeds binocular cameras in the fenders on both sides of the vehicle body, which can effectively capture the side and rear areas of the vehicle body, thereby filling the side blind spots of traditional front or rear view cameras. It is very suitable for low-speed parking, narrow passage and pedestrian / non-motorized vehicle collision avoidance scenarios.
[0018] This utility model designs the connection structure for mounting the binocular camera on the camera bracket as an adjustable angle structure, so that the binocular camera can be adapted to the fender curvature of different vehicle models to meet the usage requirements.
[0019] This invention incorporates a heating wire arranged within an embedded shell and a temperature sensor installed inside, thereby dynamically adjusting the heating power of the heating wire according to the ambient temperature to prevent the lens clarity from being affected by rain or snow.

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.
[0029] Example 1
[0030] As shown in the figure, the embedded shell 1 is adapted to the embedded groove provided on the fender 100, and the embedded shell 1 is installed in the embedded groove of the fender 100. The schematic diagram after installation is shown below. Figure 3 and Figure 4 .
[0031] The embedded shell 1 is connected to the rear shell 2, and a waterproof adhesive is provided at the connection point between the embedded shell 1 and the rear shell 2, forming a waterproof and sealed cavity. An air vent 21 is provided on the rear shell 2, and a waterproof and breathable membrane 4 is fixed to the air vent 21 by heat welding to dissipate heat from the cavity formed by the embedded shell 1 and the rear shell 2.
[0032] A heating wire 10 is arranged inside the embedded shell 1, and a temperature sensor is installed inside the cavity formed by the embedded shell 1 and the rear shell 2 to detect the temperature inside the cavity. This allows the heating power of the heating wire 10 to be dynamically adjusted according to the ambient temperature, preventing the clarity of the lens from being affected by rain or snow. It should be noted that the temperature sensor is used to detect the temperature inside the cavity. The detected information is transmitted to the vehicle control system, and the controller in the system transmits control commands to the heating wire 10 to control the heating status of the heating wire 10.
[0033] A viewing port 11 is provided on the front side of the embedded housing 1, and a waterproof viewing window cover 9 is installed at the viewing port 11 of the embedded housing 1. Mounting holes 22 are provided on both sides of the rear housing 2, so that the rear housing 2 can be connected to the fender 100 with screws, realizing the detachability of the entire camera module, which can be quickly replaced, reducing maintenance costs and avoiding the need to replace the camera module together when replacing the fender.
[0034] A camera bracket 5 is installed in the cavity formed by the embedded shell 1 and the rear shell 2. The camera bracket 5 is mounted on the rear shell 2, and a shock-absorbing silicone pad 3 is provided between the camera bracket 5 and the rear shell 2. The embedded shell 1 and the rear shell 2 can provide good protection for the internal binocular camera 6. The shock-absorbing silicone pad 3 can also be used to buffer the vibration transmitted from the rear shell 2 to the camera bracket 5, further protecting the binocular camera 6.
[0035] A binocular camera 6 is mounted on the camera bracket 5 using an adjustable angle. Connecting shafts 7 are located at both ends of the binocular camera 6, connecting to the camera bracket 5. A limiting screw 8 is installed in the guide groove 51 on the camera bracket 5. The front end of the limiting screw 8 is threaded into a threaded hole on the binocular camera 6, and the side wall of the binocular camera 6 is in contact with the camera bracket 5. This allows for angle adjustment by rotating the limiting screw 8 to release the limiting of the binocular camera 6, enabling adjustment of the pitch angle of the binocular camera 6 using the connecting shaft 7 as the axis. After adjustment, the limiting screw 8 is tightened, causing the nut of the limiting screw to move towards the binocular camera 6, providing a clamping force to the camera bracket 5. This increases the friction between the camera bracket 5 and the side wall of the binocular camera 6, thus limiting and fixing the binocular camera 6. This allows the binocular camera 6 to adapt to the fender curvature of different vehicle models to meet various usage requirements.
[0036] Furthermore, the binocular camera 6 uses a miniaturized camera module, such as a 1 / 2.5-inch CMOS sensor, with a total thickness of ≤30mm, making the overall size of the binocular camera 6 small, thus adapting to the internal space of the fender for installation.
[0037] Example 2
[0038] In use, the tilt of the binocular camera 6 is first adjusted according to the condition of the vehicle's fender. Then, the camera bracket 5 is installed onto the rear shell 2 according to the component connection instructions in Embodiment 1. After the rear shell 2 and the inner shell 1 are assembled, they are embedded into the fender 100 of the vehicle. The binocular camera's shooting range is... Figure 5 As shown, the vision system designed in this application is installed inside the fenders on both sides of the vehicle body, which can effectively capture the side and rear areas of the vehicle body, thereby filling the side blind spots of traditional front or rear view cameras. It is very suitable for low-speed parking, narrow passage, and pedestrian / non-motorized vehicle collision avoidance scenarios.
