Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted monitoring equipment technology, specifically to a highway vehicle-mounted patrol device based on a panoramic camera and a monocular detail camera. Background Technology

[0002] Traditional highway inspections rely primarily on manual labor, which is labor-intensive and inefficient. The emergence of vehicle-mounted highway inspection equipment overcomes the shortcomings of manual inspections. By capturing real-time road conditions through vehicle-mounted cameras and automatically analyzing road conditions using big data algorithm models, the inspection scope is not limited to road surface defects, but can also include bridge and tunnel structures, traffic safety incidents, and ancillary facilities, thereby improving inspection efficiency and accuracy while reducing manpower and material costs.

[0003] Existing highway vehicle-mounted patrol equipment includes a mount and a vehicle-mounted camera unit mounted on the mount. The vehicle-mounted camera unit, to accommodate both panoramic and detailed observation, typically uses a panoramic camera and a monocular detail camera. The monocular detail camera focuses on capturing high-resolution images of a specific area, and when detailed observation of a particular point in the panoramic image captured by the panoramic camera is needed, the monocular detail camera rotates to face that point and captures the image. However, highway vehicle-mounted patrol equipment is often used at night as well. This application proposes an effective combination of a panoramic camera, a monocular detail camera, and a lighting component. Utility Model Content

[0004] The purpose of this invention is to provide a highway vehicle-mounted inspection device with a reasonable structure and reliable use, based on a panoramic camera and a monocular detail camera. It effectively combines a panoramic camera, a monocular detail camera and a lighting component into one unit, ensuring the panoramic observation, detailed observation and lighting needs of the inspection device, saving space and providing unobstructed views.

[0005] The technical solution of this utility model is: A highway vehicle-mounted inspection device based on a panoramic camera and a monocular detail camera includes a support base, a camera unit, and an illumination unit. Its key technical features are: a cylindrical base is provided on the upper surface of the support base; a rotatable cylinder is provided above the cylindrical base; a fixed cylinder is provided above the rotatable cylinder; the bottom surface of the fixed cylinder has a hollow structure and a column is provided at its center; a hollow support plate is provided inside the cylindrical base, and a positioning groove is provided at the center of the hollow support plate; the lower end of the column is located in the positioning groove and is fixedly connected; the camera unit includes four fisheye lens modules fixed around the side wall of the fixed cylinder and a monocular detail camera module fixed on the side wall of the rotatable cylinder; a gear ring structure is provided on the lower part of the side wall of the rotatable cylinder; a transmission mechanism connected to the gear ring structure is provided on the support base; the illumination unit includes a branch pipe fixed to the center of the top surface of the fixed cylinder, a support cover provided at the upper end of the branch pipe, an annular infrared supplementary light tube provided on the lower surface of the support cover, and an ambient light sensor provided at the edge of the support cover.

[0006] In the aforementioned highway vehicle-mounted inspection equipment based on panoramic cameras and monocular detail cameras, the center lines of the cylinder base, rotatable cylinder, fixed cylinder, and annular infrared supplementary light tube coincide.

[0007] The aforementioned highway vehicle-mounted inspection equipment based on panoramic cameras and monocular detail cameras has a lower cover in the middle of the support base, and a cable connector for connecting the fisheye lens module and monocular detail camera module of the camera unit is located at the center of the lower cover.

[0008] The aforementioned highway vehicle-mounted patrol equipment based on panoramic cameras and monocular detail cameras includes a transmission mechanism comprising a motor fixed to the upper surface of a support base and a gear located on the motor output shaft and meshing with a gear ring structure.

[0010] The beneficial effects of this utility model are: 1. The structure utilizes a base, a rotatable tube, and a fixed tube to form a support structure for four fisheye lens modules and a monocular detail camera module. The four fisheye lens modules face the four sides of the fixed tube to achieve panoramic shooting, while the monocular detail camera module can rotate to the required orientation for detail shooting under the drive of the transmission mechanism and gear ring structure, saving space and eliminating obstructions.

[0011] 2. The ring-shaped infrared filler tube of the lighting unit is fixed above the fixed cylinder. When the ambient light sensor detects insufficient ambient light, it will automatically emit infrared light, so that the camera unit can capture clear black and white images at night.

[0014] The present invention will be described in detail with reference to the accompanying drawings.

[0015] like Figures 1-4 As shown, the highway vehicle-mounted inspection equipment based on a panoramic camera and a monocular detail camera includes a support base 10, a camera unit, and a lighting unit.

[0016] The support base 10 has a cylindrical base 9 on its upper surface, a rotatable cylinder 6 above the cylindrical base 9, and a fixed cylinder 4 above the rotatable cylinder 6. The bottom surface of the fixed cylinder 4 is hollow, and a column 13 is located at its center. The interior of the cylindrical base 9 has a hollow support plate 16 with a positioning groove at its center. The lower end of the column 13 is located in the positioning groove and is fixedly connected. The lower part of the side wall of the rotatable cylinder 6 has a gear ring structure 8. The support base 10 has a transmission mechanism connected to the gear ring structure 8. In this embodiment, the transmission mechanism includes a motor 15 fixed to the upper surface of the support base 10 and a gear 14 located on the output shaft of the motor 15 and meshing with the gear ring structure 8. The upper and lower edges of the rotatable cylinder 6 are respectively provided with annular limiting bosses, and the bottom edge of the fixed cylinder 4 and the upper edge of the cylindrical base 9 are respectively provided with limiting grooves that cooperate with the annular limiting bosses.

[0017] The camera unit includes four fisheye lens modules 5 fixed around the side wall of the fixed cylinder 4 and a monocular detail camera module 7 fixed on the side wall of the rotatable cylinder 6. The lighting unit includes a branch pipe 12 fixed to the center of the top surface of the fixed cylinder 4, a support cover 1 located at the upper end of the branch pipe 12, an annular infrared fill light tube 3 located on the lower surface of the support cover 1, and an ambient light sensor 2 located at the edge of the support cover 1. The center lines of the cylinder base 10, the rotatable cylinder 6, the fixed cylinder 4, and the annular infrared fill light tube 3 coincide.

[0018] The support base 10 has a lower cover 17 in the middle, and the lower cover 17 has a cable connector 11 at its center for connection to the fisheye lens module 5 and the monocular detail camera module 7 of the camera unit. The four fisheye lens modules 5 and the monocular detail camera module 7 each use the same type of image sensor. One of the fisheye lens modules' image sensors acts as the master image sensor, and the other image sensors (slave image sensors) are synchronously connected via frame lines. All four fisheye lens modules and the monocular detail camera module respond synchronously to shooting commands, using the same exposure time. See also... Figure 4This paper demonstrates the connection logic of a multi-sensor synchronization system, primarily used for master-slave mode configuration of image sensors in various lens modules, ensuring that multiple image sensors work collaboratively in the same time sequence. The key components and their connections are as follows: The master image sensor, acting as the system's master device, generates synchronization and clock signals to drive the timing of its own operation and that of the slave image sensors. Specifically, it outputs a vertical synchronization signal to mark the start of a frame and control frame synchronization; a horizontal synchronization signal to mark the start of a row of pixels and control row synchronization; and an input clock to provide a clock reference for pixel sampling and data processing within the sensor. The slave image sensors, acting as slave devices, receive the synchronization signal output from the master image sensor and the clock signal provided by an external oscillator to maintain timing consistency with the master image sensor. They obtain the synchronization signal from the master image sensor to ensure alignment with the frame / row start time of the master device. The input clock is provided by an external oscillator, not the output of the master image sensor. The oscillator provides a stable clock signal to the slave image sensors, and its frequency determines the sampling rate of the image sensors.

[0019] Working principle: 1. During assembly, place the rotatable cylinder 6, which holds the monocular detail camera module 7, onto the cylinder base 9. Then, place the fixed cylinder 4 above the rotatable cylinder 6, ensuring that the lower end of the column 13 is connected and fixed to the positioning groove inside the cylinder base 9, without affecting the rotation of the rotatable cylinder 6. Afterward, connect the output cables of the four fisheye lens modules 5 and the monocular detail camera module 7 to the cable connector 11, and then connect and fix the lower cover 17 to the support base 10.

[0020] 2. The four fisheye lens modules 5 and the monocular detail camera module 7 work synchronously. When it is necessary to observe a certain point in the panoramic image in detail, the remote terminal starts the motor 15. The motor 15 drives the rotatable cylinder 6 and the monocular detail camera module 7 to rotate toward that point through the gear 14 and the gear ring structure 8, so that the monocular detail camera module 7 can be turned toward that point for high-definition observation.

[0021] 3. When the ambient light sensor 2 detects insufficient ambient light, the ring infrared fill light tube 3 automatically emits infrared light, enabling the camera unit to capture clear black and white images even at night.

[0022] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
