Description

Technical Field

[0001] This utility model relates to the field of surveillance camera technology, specifically to a link structure for synchronizing single-lens cameras and panoramic cameras. Background Technology

[0002] To achieve comprehensive monitoring, panoramic cameras are typically used. These cameras capture a 360-degree field of view through their individual lens modules and transmit the data to the monitoring terminal. This type of camera is suitable for environments requiring large-scale monitoring, especially those involving high population mobility and complex scenes. Single-detail lenses, on the other hand, focus on capturing high-definition images of specific areas. Integrating a single-detail lens with a panoramic camera allows users to achieve both wide-area coverage and detailed observation, building upon wide-angle or panoramic images. However, currently, once assembled with a panoramic camera, the orientation of the single-detail lens is fixed and cannot be adjusted independently. Utility Model Content

[0003] The purpose of this invention is to provide a reasonably structured and reliable link structure for synchronizing single-lens cameras and panoramic cameras, solving the problem that the orientation of a single-detail lens cannot be adjusted independently, ensuring the synchronous operation of the single-detail lens and the panoramic camera, and taking into account both large-scale monitoring and local detail observation.

[0004] The technical solution of this utility model is: A link structure for synchronizing a single-lens camera and a panoramic camera includes a vertical tube, a panoramic camera, and a single-detail lens camera. The panoramic camera includes four fisheye lens modules fixed around the vertical tube. The key technical features are: a rotatable positioning cylinder is provided at the top of the vertical tube; the single-detail lens camera includes a single-detail lens module fixed to the side wall of the rotatable positioning cylinder; an annular slider is provided on the lower end face of the rotatable positioning cylinder; an annular groove that mates with the annular slider is provided on the top face of the vertical tube; a gear ring is built into the lower part of the rotatable positioning cylinder; a motor is built into the top of the vertical tube; and a drive gear that meshes with the gear ring is provided on the output shaft of the motor. The four fisheye lens modules and the single-detail lens modules each use the same type of image sensor, with one fisheye lens module's image sensor serving as the master image sensor and connected to the other image sensors via frame-by-frame synchronization.

[0005] The aforementioned link structure for synchronizing single-lens cameras and panoramic cameras has a wiring hole at the center of the top surface of the vertical cylinder that communicates with the rotatable positioning cylinder.

[0006] In the aforementioned link structure for synchronizing single-lens cameras and panoramic cameras, the cross-section of the annular slider is T-shaped.

[0007] In the aforementioned link structure for synchronizing single-lens cameras and panoramic cameras, the optical axis of the single-detail lens module is inclined to the horizontal plane.

[0008] The aforementioned link structure for synchronizing single-lens cameras and panoramic cameras includes a supporting skirt along the lower edge of the vertical cylinder, and a set of mounting holes on the supporting skirt.

[0009] The beneficial effects of this utility model are: 1. Four fisheye lens modules are used to achieve panoramic monitoring, while single-detail lens modules that work synchronously are used to observe local details. When it is necessary to observe a certain point in the panoramic image, the motor drives the rotatable positioning cylinder and the single-detail lens module to rotate toward that point through the drive gear and gear ring. This allows the single-detail lens module to face that point for local detail observation, solving the problem that the orientation of the single-detail lens cannot be adjusted independently. It does not require the entire structure to rotate, reducing the difficulty of installation.

[0010] 2. The four fisheye lens modules and the single detail lens module of this utility model use the same type of image sensor. The image sensor of one of the fisheye lens modules serves as the main image sensor and is connected to the other image sensors through frame-line synchronization to ensure the synchronous operation of the single detail lens and the panoramic camera, thus taking into account both large-area monitoring and local detail observation.

[0013] The present invention will be described in detail with reference to the accompanying drawings.

[0014] like Figures 1-3 As shown, the link structure for synchronizing a single-lens camera and a panoramic camera includes a barrel 3, a panoramic camera, and a single-detail lens camera 2. The panoramic camera includes four fisheye lens modules 4 fixed around the barrel 3.

[0015] The top of the vertical cylinder 3 is provided with a rotatable positioning cylinder 1, the single-detail lens camera 2 includes a single-detail lens module fixed to the side wall of the rotatable positioning cylinder 1, the lower end face of the rotatable positioning cylinder 1 is provided with an annular slider 8, the top surface of the vertical cylinder 3 is provided with an annular groove that cooperates with the annular slider 8, the lower part of the rotatable positioning cylinder 1 is built with a gear ring 9, the top of the vertical cylinder 3 is built with a motor 10, and the output shaft of the motor 10 is provided with a drive gear 7 that meshes with the gear ring 9.

[0016] The top surface of the vertical cylinder 3 has a wiring hole 11 at its center, which communicates with the rotatable positioning cylinder 1. The cross-section of the annular slider 8 is T-shaped. The lower edge of the vertical cylinder 3 has a supporting skirt 5, and the supporting skirt 5 has a set of mounting holes.

[0017] The optical axis of the single-detail lens module is tilted to the horizontal plane. The four fisheye lens modules 4 and the single-detail lens module each use the same type of image sensor. One of the fisheye lens modules 4's image sensors serves as the main image sensor and is synchronously connected to the other image sensors via frame-by-frame synchronization. All four fisheye lens modules 4 and the single-detail lens module respond synchronously to shooting commands and use the same exposure time.

[0018] See Figure 3 This 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 following are the functions and connections of the key components: The master sensor, 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.

[0019] The slave image sensor, acting as a slave device, receives a synchronization signal from the master image sensor and a clock signal from an external oscillator to maintain timing consistency with the master image sensor. The synchronization signal is obtained from the master image sensor to ensure alignment with the frame / line start time of the master device. The input clock is provided by an external oscillator, not the master image sensor output. The oscillator provides a stable clock signal to the slave image sensor, and its frequency determines the sampling rate of the image sensor.

[0020] Working principle: Fix this device at the monitoring location.

[0021] Four fisheye lens modules 4 and a single detail lens module work synchronously. When it is necessary to observe a specific point in the panoramic image in detail, the remote terminal starts the motor 10. The motor 10 drives the rotatable positioning cylinder 1 and the single detail lens module to rotate toward that point through the drive gear 7 and the gear ring 9, so that the single detail lens module is facing that point for high-definition observation.

[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.
