Description

Technical Field

[0001] This invention relates to the field of intelligent driving environment perception equipment technology, specifically to an intelligent driving multi-vision fusion target detection and positioning device. Background Technology

[0002] As intelligent driving technology rapidly advances to L2+ and higher levels, the demand for 360° all-around environmental perception, accurate target recognition in complex scenes, and robust positioning continues to increase. Existing in-vehicle visual perception systems mostly use a single camera or a simple stitching scheme, which has problems such as limited perception field of view, poor adaptability to adverse scenes such as rain, fog, backlight, and obstruction, low efficiency of multi-source data fusion, insufficient target detection accuracy, and poor heat dissipation during long-term operation. These issues make it difficult to meet the stringent safety and reliability requirements of autonomous driving. At the same time, traditional in-vehicle rearview mirrors have limited functions and cannot take into account both environmental monitoring and auxiliary perception, resulting in a waste of in-vehicle perception resources.

[0003] To address the technical problems of insufficient perception capabilities, weak scene adaptability, poor heat dissipation performance, and low functional integration in the existing technologies, we propose an intelligent driving multi-vision fusion target detection and localization device.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1:

[0028] Please see Figure 1-2 This invention provides a technical solution: an intelligent driving multi-vision fusion target detection and positioning device, including a connecting rod 1, a data cable 2 on the lower side of the outer surface of the connecting rod 1, a threaded head 6 fixedly connected to the upper end of the connecting rod 1, a threaded sleeve 7 meshing with the outer surface of the threaded head 6, a connector 5 on the front upper part of the outer surface of the connecting rod 1, a control mechanism 4 jointly provided at the upper end of the threaded sleeve 7 and the connector 5, and a rearview mirror assembly 3 jointly provided at the lower end of the connecting rod 1 and the data cable 2. By adding the connecting rod 1, the threaded head 6 and the threaded sleeve 7, the rearview mirror assembly 3 is installed on the control mechanism 4. The data cable 2 and the connector 5 are used for electrical connection between the rearview mirror assembly 3 and the control mechanism 4, so that the control mechanism 4 can control the rearview mirror assembly 3.

[0029] It should be noted that the specific installation method, circuit connection method, and control method of data cable 2 and connector 5 are all conventional designs, which are standard design practices for designers. Specifically, the control mechanism 4 is first installed on the front side of the top of the driver's and passenger's seats, fitting snugly against the upper side of the windshield. Then, the threaded head 6 on connecting rod 1 is engaged with the threaded sleeve 7. Afterwards, the rearview mirror assembly 3 is joined to the control mechanism 4. Next, connector 5 is inserted into the lower side of the control mechanism 4, connecting it to relevant vehicle wiring. Starting the vehicle activates the control mechanism 4, which connects to the vehicle's central control platform. The central control platform can then control the control mechanism 4 in real time, controlling the rearview mirror assembly 3. This, combined with the vehicle's surround camera, forms a multi-visual perception, multi-modal fusion, and edge-to-edge collaborative operation system, achieving high-precision target detection and robust positioning in a 360° environment. This supports L2+ level and above autonomous driving functions, and is particularly suitable for challenging scenarios such as rain, fog, backlight, and obstructions.

[0030] Further explanation as follows Figure 3-4As shown, the control mechanism 4 includes an upper cover 41, with four positioning holes 42 on the rear side of the upper end. Each of the four positioning holes 42 is fitted with a countersunk screw 43. An installation hole 44 is provided in the middle of the front side of the upper cover 41. A connecting sleeve rod 46 is fixedly connected to the inner cavity of the installation hole 44. A high-definition camera 45 is provided in the inner cavity of the connecting sleeve rod 46. Two threaded sleeve rods 48 are fixedly connected to the left and right sides of the lower side of the inner cavity of the upper cover 41. The inner cavities of the four threaded sleeve rods 48 and the high-definition camera 45 are jointly provided with a control group 47. A symmetrical filter screen 49 is provided on the upper rear side of the outer surface of the upper cover 41.

[0031] It should be noted that the specific installation method, circuit connection method, and control method of the high-definition camera 45 are all conventional designs, which are standard design practices for designers. Specifically, when installing the control mechanism 4 onto the vehicle, first disassemble the threaded sleeve 48 from the control assembly 47, then disassemble the high-definition camera 45 from the control assembly 47. Next, place the upper cover 41 against the pre-drilled mounting hole on the front side of the top of the driver's cab and passenger side, ensuring the inclined surface of the upper cover 41 is flush with the upper side of the windshield. Then, insert the countersunk screw... 43 penetrates the positioning hole 42 and engages with the mounting hole to complete the fixed installation of the top cover 41. Then, the high-definition camera 45 is connected to the control group 47 and placed on the lower side of the top cover 41. The fixed installation with the control group 47 is completed by the threaded sleeve rod 48. In the initial state, the connecting rod 1, data cable 2, connector 5 and rearview mirror assembly 3 can be regarded as a whole. After the installation of the top cover 41 and the control group 47 is completed, the threaded head 6 on the connecting rod 1 engages with the threaded sleeve rod 7 to finally complete the fixed installation of the entire device.

[0032] To further explain, such as Figure 5-7 As shown, the control group 47 includes a bottom shell 471. Two positioning holes 472 are opened on the left and right sides of the upper rear side of the bottom shell 471. Countersunk screws 473 are fitted into the inner cavities of the four positioning holes 472. A wiring slot 475 is provided at the lower end of the bottom shell 471. The control group 474 is provided on the upper rear side of the bottom shell 471 and the wiring slot 475. The lower end of the top cover 41 fits against the upper end of the bottom shell 471. The upper surface of the four countersunk screws 473 is respectively engaged with the inner cavity of the four threaded sleeves 48. The upper end of the threaded sleeves 7 is fixedly connected to the middle of the lower end of the bottom shell 471. The input end of the wiring head 5 is connected to the output end of the wiring slot 475.

[0033] Control unit 2 474 includes a circuit board 4741. A connector 4746 is located on the front upper side of the circuit board 4741. An intelligent control component 4742 is located in the middle of the upper upper side of the circuit board 4741. A heat sink 4745 is fixedly connected to the upper end of the circuit board 4741. A partition plate 4744 is fixedly connected to the middle of the rear upper side of the circuit board 4741. A miniature heat sink 4743 is located on the right rear upper side of the circuit board 4741. A wiring slot 475 is fixedly connected to the rear upper side of the bottom shell 471 at the lower end of the circuit board 4741. The input terminal of the wiring slot 475 is electrically connected to the circuit board 4741. The lower end of the heat sink 4745 is attached to the upper surface of the outer surface of the intelligent control component 4742. The rear end of the partition plate 4744 is fixedly connected to the middle of the rear side of the inner cavity of the upper cover 41, and the partition plate 4744 is located between two filters 49. On the front side, the miniature heat sink 4743 and the filter screen 49 on the right side are on the same horizontal plane. A wiring slot 475 is added for electrical connection with the wiring head 5. A positioning hole 472 is provided to facilitate the engagement of the countersunk screw 473 and the threaded sleeve 48, which can fix the bottom shell 471 and the top cover 41. A heat dissipation fin 4745 is added to transfer the heat generated by the intelligent control component 4742 to the surrounding air. The hot air is then discharged by activating the miniature heat sink 4743. A partition plate 4744 is added to separate the two filters 49. When the miniature heat sink 4743 discharges hot air through the filter screen 49 on the right side, the cool air on the outer surface enters from the filter screen 49 on the left side to cool the inside of the device, thus completing the heat dissipation operation.

[0034] It should be noted that the specific installation methods, circuit connection methods, and control methods of the wiring slot 475, circuit board 4741, intelligent control component 4742, micro heat sink 4743, and connector 4746 are all conventional designs and are standard design methods used by designers. The intelligent control component 4742 is connected to the relevant wiring on the vehicle. The intelligent control component 4742 is equipped with a multi-source data acquisition and spatiotemporal synchronization unit, IMU, control mechanism 4D millimeter-wave radar, fusion perception layer unit, multi-visual feature extraction and BEV fusion unit, etc. It works in conjunction with the target detection, vehicle positioning, and multi-camera array of the surround camera in the vehicle's central control platform, and works in conjunction with the rearview mirror assembly 3 to form multi-visual perception, multi-modal fusion, and edge-to-edge collaborative operation, achieving high-precision target detection and robust positioning in a 360° environment, and can support Level 2+ and above autonomous driving functions.

[0035] In detail, after the upper cover 41 is fixed, the high-definition camera 45 is electrically connected to the connector 4746. Then, the bottom shell 471 is placed on the lower side of the inner cavity of the upper cover 41. Next, the countersunk screw 473 is inserted through the positioning hole 472 and engaged with the inner cavity of the threaded sleeve 48, thereby completing the installation of the control group 47 and the upper cover 41. After installation with the rearview mirror assembly 3, starting the vehicle can drive the entire device to run. During long-term operation, the intelligent control component 4742 generates heat and transfers it to the heat dissipation fins 4745. Then, the heat dissipation fins 4745 transfer the heat to the air in the inner cavity of the upper cover 41. When the temperature reaches the threshold, the intelligent control component 4742 will also control the operation of the micro radiator 4743. By activating the micro radiator 4743, the hot air around the heat dissipation fins 4745 is discharged through the filter screen 49 on the right side. The cold air enters the inner cavity of the upper cover 41 from the inner cavity of the filter screen 49 on the left side, cooling the inside of the device and thus completing the heat dissipation operation. The filter screen 49 also serves as a dustproof device.

[0036] To further explain, such as Figure 8-9 As shown, the rearview mirror assembly 3 includes a rear cover 31. A rotating groove 33 is provided in the middle of the front end of the rear cover 31. A ball rod 32 is rotatably connected to the inner cavity of the rotating groove 33. A circuit control board 36 is provided on the left side of the inner cavity of the rear cover 31. A high-definition camera 37 is provided on the upper right side of the rear end of the circuit control board 36. A connecting line 35 is provided on the left side of the outer surface of the circuit control board 36. A liquid crystal mirror 34 is provided on the rear end of the rear cover 31 and the side of the connecting line 35 away from the circuit control board 36. The lower end of the connecting rod 1 is fixedly connected to the ball rod 32. The end of the data cable 2 away from the connecting rod 1 passes through the rear cover 31 and is electrically connected to the circuit control board 36. The side of the data cable 2 away from the rear cover 31 is electrically connected to the connector 5.

[0037] It should be noted that the specific installation methods, circuit connection methods, and control methods of the LCD mirror 34, connecting wire 35, circuit control board 36, and high-definition camera 37 are all conventional designs and are standard design practices. Through data cable 2, connector 5, and 457, the circuit control board 36, high-definition camera 37, and LCD mirror 34 are controlled by the intelligent control component 4742. Specifically, the lower end of connecting rod 1 is fixedly connected to ball rod 32. Because ball rod 32 is rotatably connected to rotating slot 33, the angle of rear cover 31 can be flexibly adjusted. After the entire device is installed in the vehicle, starting the vehicle allows control of the circuit control board 36. The circuit control board 36 controls the high-definition camera 37 to observe the interior environment of the vehicle. The camera is electrically connected to connecting sleeve rod 46 via connecting wire 35. The LCD mirror 34 can display the surrounding environment of the vehicle, compensating for blind spots in human vision. When no display is needed, the LCD mirror 34 can be used as a regular rearview mirror.
