[0025] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] The terms "first," "second," "third," "fourth," and the like (if any) in the specification and claims of the present application and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in orders other than those illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, e.g., a product or apparatus comprising a series of steps or units is not necessarily limited to those units explicitly listed, but may include other units not explicitly listed or inherent to those products or apparatuses.

[0028] In the field of autonomous driving, to ensure the safety of autonomous driving, the driver's driving status needs to be monitored in real time while the vehicle is driving automatically. The system monitors whether the driver is observing the road ahead, whether their driving posture is dangerous, and whether the driver is smoking. When incorrect driver behavior is detected, prompt reminders are issued to ensure the safety of the autonomous driving process. Therefore, in order to accurately monitor the driver's driving status, it is necessary to reasonably set up in-vehicle cameras in appropriate locations to accurately capture the driver's status and avoid missing information. However, the most common practice is to set up a camera directly in front of the driver to monitor the driver's status. This method cannot effectively obtain information below the driver's head and waist. When the driver's sitting posture is incorrect, relevant information cannot be obtained to issue reminders.

[0029] In response to the above problems, the present application proposes a movable camera bracket and an ICP multi-camera video acquisition system. The camera bracket includes: an upper crossbar, one end of which is fixedly connected to the inherent hole in the vehicle A-pillar on the other side of the driver, and the other end extends to the middle of the vehicle dashboard. It is located above the vehicle dashboard and is bent according to the shape of the dashboard; a first connecting rod, one end of which is fixedly connected to the middle of the upper crossbar and the other end passes downward through the vehicle dashboard; a lower crossbar, one end of which is fixedly connected to the other end of the first connecting rod and the other end extends toward the driver's side, wherein at least one camera is set on the upper crossbar and / or the lower crossbar, which can be moved left and right and rotated to shoot the driver's driving status.

[0030] The movable camera bracket of the present application is fixedly supported by the inherent holes in the A-pillar of the vehicle, and is fixed by the vehicle's own structure and holes. There is no need to make major changes to the vehicle, which saves costs and is simple and easy. By setting the upper and lower cross bars, the camera can be changed in position and adjusted in angle, thereby determining the optimal shooting position and angle of the camera to ensure monitoring of the driver's driving status. Due to the differences in height, body shape, and driving habits of drivers, a fixed-position camera will not be able to meet the requirements for driver monitoring status detection. By adjusting the camera position and angle, the shooting requirements of different drivers can be met, ensuring the safety of the autonomous driving process. At the same time, the acquired monitoring data is of great significance to the research on the autonomous driving process and the camera position setting of vehicle manufacturers.

[0031] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0032] Figure 1 A structural schematic diagram of an embodiment of the movable camera bracket of the present application is shown.

[0033] exist Figure 1 In the embodiment shown, the movable camera bracket of the present application includes an upper cross bar 101, one end of which is fixedly connected to the vehicle A-pillar on the other side of the driver, and the other end extends to the middle of the vehicle dashboard. It is located above the vehicle dashboard and is bent according to the shape of the dashboard.

[0034] In this embodiment, one end of the upper cross bar is fixedly connected to the vehicle's A-pillar on the other side of the driver. The fixed connection is made using the original holes of the vehicle's A-pillar itself. The connection method includes but is not limited to bolt connection. By using the vehicle's A-pillar as a support point for the camera bracket, there is no need to add an additional fixed structure, saving design costs and bracket space. The other end of the upper cross bar extends to the middle of the vehicle's dashboard and is located above the vehicle's dashboard. The specific structure of the dashboard will vary depending on the vehicle model. Correspondingly, the upper cross bar is also designed with an adaptive bending design to meet the design requirements of different vehicles.

[0035] Figure 2 A structural schematic diagram of an example of a movable camera bracket of the present application is shown.

[0036] like Figure 2 As shown, one end of the upper crossbar 101 is fixed by the vehicle A-pillar for support. The upper crossbar is fixed by the existing hole position of the vehicle A-pillar, and no additional fixing parts are needed, which is simple and easy.

[0037] Specifically, the upper cross bar can be a round tube, wherein the thickness, strength and other characteristics of the upper cross bar can be reasonably selected according to actual design requirements, and this application does not impose any specific restrictions.

[0038] exist Figure 1 In the illustrated embodiment, the movable camera bracket of the present application includes a first connecting rod 102 , one end of which is fixedly connected to the middle portion of the upper crossbar, and the other end of which passes downward through the vehicle dashboard.

[0039] In this embodiment, the first connecting rod is fixedly connected to the middle part of the upper cross bar, and the connection mode can be selected to be welding. The other end extends downward through the vehicle instrument panel and serves as a connecting piece of the lower cross bar at the back.

[0040] exist Figure 1 In the illustrated embodiment, the movable camera bracket of the present application includes a lower cross bar 103 , one end of which is fixedly connected to the other end of the first connecting bar, and the other end of which extends toward the driver's side.

[0041] In this embodiment, one end of the lower crossbar is fixedly connected to the other end of the first connecting rod, with the first connecting rod serving as a support point. The other end of the lower crossbar extends toward the driver's side to an appropriate distance. The lower crossbar is located on the lower front side of the instrument panel. When designing the specific position, it is best not to affect the driver's driving operation. By setting up the upper and lower crossbars, at least one camera is set on the upper crossbar and / or the lower crossbar. The camera can move laterally and rotate along the crossbar on the upper and lower crossbars, thereby accommodating drivers of different body shapes and different driving habits of drivers, such as the forward or backward position of the driver's seat. This achieves perfect capture of the driver's driving status, and promptly alerts the driver of incorrect driving behavior, ensuring the safety of the autonomous driving process.

[0042] Optional, Figure 3 FIG. 1 shows a structural diagram of an example of a movable camera bracket of the present application. Figure 3 As shown, the upper crossbar and / or the lower crossbar are provided with an angle adjustment member 104 for fixing the camera, wherein the position and angle of the angle adjustment member are adjusted to achieve lateral movement and rotation of the camera.

[0043] In this optional embodiment, to facilitate camera position adjustment, angle adjustment members are provided on the upper and / or lower crossbars. These members secure the camera, allowing adjustment of the camera's position and angle by changing the position and angle of the members. The angle adjustment members can be existing rotatable components, such as hinges or bolts. A clamping structure, such as a clamp, can be used to secure the angle adjustment members to the upper and / or lower crossbars, facilitating both removal and installation. The angle adjustment members can rotate vertically and / or horizontally.

[0044] Optionally, a length scale is provided on the upper crossbar and / or the lower crossbar to mark the position of the camera; and an angle scale is provided on the angle adjustment member to mark the angle of the camera.

[0045] In this optional embodiment, to more accurately control the camera's position, length scales are provided on the upper and / or lower crossbars, and angle scales are provided on the angle adjustment member. This scale setting allows for quantification of the camera's position, enabling both qualitative and quantitative analysis of the camera's position. By recording the driver's driving status at different camera positions, the background processor can analyze the optimal angle and position for the shots, thereby providing guidance to vehicle manufacturers regarding subsequent camera installation.

[0046] Optional, Figure 4 A structural schematic diagram of an embodiment of the movable camera bracket of the present application is shown.

[0047] exist Figure 4In the embodiment shown, the movable camera bracket of the present application also includes: a second connecting rod 201, one end of which is fixedly connected to the lower cross bar; a camera fixing plate 202, one end of which is fixedly connected to the other end of the second connecting rod and supported by the second connecting rod; a support rod 203, one end of which is fixedly connected to the other end of the camera fixing plate, and the other end of which is fixedly connected to the bottom of the vehicle, for supporting the camera fixing plate, wherein the camera is set on the camera fixing plate.

[0048] In this embodiment, in order to expand the installation position of the camera and to better capture the driver's driving status, the movable camera bracket of the present application is also provided with a second connecting rod 201, a camera fixing plate 202 and a support rod 203.

[0049] One end of the second connecting rod is fixedly connected to the lower crossbar, while the other end extends upward and is fixedly connected to one end of the camera mounting plate. The camera is mounted on the mounting plate, where it can be adjusted and angled according to actual shooting needs. The other end of the mounting plate is fixedly connected to one end of a support rod, which in turn is fixedly connected to the bottom of the vehicle, supporting the mounting plate.

[0050] Specifically, the camera mounting plate is located between the driver and co-pilot, and its specific position does not affect the driver's driving operation. The camera mounting plate can be fixed to the second connecting rod and support rod using welding or clamps. Clamps offer the advantage of easy disassembly. Welding reduces the risk of loosening between connected components, providing a certain degree of stability. The specific installation location and connection method can be selected based on the design requirements of the specific situation.

[0051] Optional, Figure 5 An embodiment of the camera fixing plate of the present application is shown. Figure 5 As shown, the camera fixing plate includes: a slide rail 2021, which is arranged on the upper surface of the camera fixing plate; a slider 2022, which is engaged with the slide rail and slides along the slide rail, wherein the camera is set on the slider and its position is adjusted as the slider slides.

[0052] In this optional embodiment, a slide rail is provided on the camera mounting plate, and a slider can be provided on the slide rail, wherein the slider can slide along the slide rail to achieve position change. The camera can be mounted on the slider, and the camera position can be adjusted by sliding the slider.

[0053] Specifically, the slide rails can be arranged appropriately according to actual requirements. For example, a single slide rail can be arranged along the direction of the camera fixing plate, or cross-shaped slide rails can be arranged, etc. The specific slide rail arrangement is not specifically limited in this application.

[0054] Optional, Figure 6 An embodiment of the camera fixing plate of the present application is shown.

[0055] In this alternative embodiment, to accommodate different heights, a third connecting rod is provided on the slider. One end of the third connecting rod is fixedly connected to the slider, and the other end is provided with an angle adjustment member. The camera is mounted on the angle adjustment member. Sliding the slider adjusts the camera's position, while rotating the angle adjustment member adjusts the camera's angle. This allows for tailored photography of different drivers. The angle adjustment member can rotate both vertically and horizontally.

[0056] Optional, Figure 7 An embodiment of the camera fixing plate of the present application is shown. Figure 7 As shown, a length scale 701 is provided on the slide rail to mark the position of the camera; an angle scale 702 is provided on the angle adjustment member to mark the angle of the camera.

[0057] In this optional embodiment, a length scale is provided on the slide rail, and an angle scale is provided on the angle adjustment member, thereby achieving a quantitative expression of the camera position and enabling better recording of the camera position.

[0058] The movable camera bracket of the present application widens the camera installation area by setting the upper crossbar, the lower crossbar and the camera fixing plate, so that the camera can better shoot and monitor the driver's driving status. In addition, the camera can be adjusted in position and angle to adapt to the monitoring of different drivers and drivers with different driving habits. By setting the length scale and the angle scale, the quantitative recording of the camera position can be achieved, and the optimal camera monitoring position can be determined more accurately. Through the subsequent analysis of the camera monitoring data, guiding opinions on the manufacturer's camera installation can be made. This can better monitor the driver's driving status and improve the safety during the autonomous driving process.
