Description

An automated linkage method for panoramic AI cameras Technical Field

[0001] This application relates to the technical field of panoramic AI cameras, and in particular to an automated linkage method for panoramic AI cameras. Background Technology

[0002] In today's rapidly developing information technology environment, industries such as telecommunications operators and power are constantly upgrading their infrastructure, resulting in a wide distribution and large number of projects in daily engineering construction. However, most existing AI cameras are fixed bullet or dome cameras, installed in fixed locations to monitor and record fixed areas for AI analysis.

[0003] Meanwhile, existing mobile AI cameras are mainly divided into two types: one is an AI camera with a pan-tilt unit, which uses a zoom pan-tilt lens for shooting and analysis. It can control the pan-tilt rotation to achieve shooting and analysis at different horizontal and vertical angles, but it cannot monitor the entire panorama at the same time, resulting in blind spots; the other is a 360° panoramic AI camera, which consists of multiple fixed-focus lenses to achieve 360° panoramic shooting and analysis, but it cannot be controlled by a pan-tilt unit or vertically adjusted, resulting in blind spots in low-lying and high-altitude areas. Summary of the Invention

[0004] The purpose of this application is to provide an automated linkage method for panoramic AI cameras to solve the problems of existing AI cameras with pan-tilt units that cannot simultaneously monitor the entire panorama and have blind spots; and existing 360° panoramic AI cameras that cannot be controlled by pan-tilt units and cannot vertically adjust their angles, resulting in blind spots in low-lying and high-altitude areas.

[0005] This application provides an automated linkage method for a panoramic AI camera, employing the following technical solution: An automated linkage method for a panoramic AI camera includes the following steps: S1. After the panoramic AI camera is powered on, the upper optical zoom lens and the four lower fixed-focus lenses automatically begin real-time monitoring and recording, as well as AI real-time analysis; S2. When no one appears in the real-time analysis frame for a cumulative duration of 5 minutes, a long-term no-person alarm message is pushed to the platform; S3. When a person enters the effective shooting range of the camera, the panoramic image composed of the four lower fixed-focus lenses captures the human figure, at which point the AI... The analysis automatically calculates which fixed-focus lens the human figure appears in; S4, then calculates the x and y axis positions of the human figure's outline pixel area in the image, and then, based on a horizontal 360° circle and a vertical 180°, calculates the human figure's orientation, thereby controlling the optical zoom lens located above to rotate to the corresponding position for zoom detail shooting; S5, once the optical zoom lens locks onto the human figure, the AI ​​analysis calculates the human figure's position in the image in real time, thereby calculating the angle that the gimbal needs to rotate, thus enabling automated linkage control of the gimbal, which in turn drives the optical zoom lens to turn to the corresponding angle to achieve automatic tracking and shooting of the person.

[0006] Furthermore, the optical zoom lens located above will automatically analyze the position of the person in real time and then automatically coordinate with the gimbal to rotate; when the person is crouching or climbing a ladder, the gimbal will be automatically controlled to track and shoot.

[0007] Furthermore, when the number of pixels occupied by the person in the entire shooting frame is small, the lens will be automatically controlled to perform optical zoom in order to achieve automatic tracking shooting.

[0008] Furthermore, the optical zoom lens located above supports gimbal control, enabling 360° horizontal rotation and a vertical swing angle between -20° and 90°, and also possesses AI analysis capabilities.

[0009] Furthermore, the four fixed-focus lenses located below are positioned in the front, back, left, and rear directions respectively. These four fixed-focus lenses can form a 360° panoramic monitoring and recording system, and have AI analysis capabilities, including human detection and analysis.

[0010] Furthermore, the panoramic AI camera also integrates an AI computing chip, enabling AI analysis and automated linkage control to be completed locally on the device.

[0011] Furthermore, the AI ​​analysis includes AI recognition and analysis capabilities such as human detection, face recognition, safety helmet detection, and safety reflective vest detection.

[0012] Compared with the prior art, the beneficial effects of this application are as follows: the solution of this application can solve the problem of 360° panoramic environmental monitoring of the construction site and automatic zoom monitoring of personnel operation details through a single device, and perform real-time AI analysis of the entire site; at the same time, through the panoramic + gimbal automated linkage solution, the problems of monitoring blind spots in low-lying and high-altitude areas and the inability to automatically track and zoom are solved. On-site operators only need to set up the equipment once, which can solve the problem of personnel frequently moving equipment or adjusting the camera angle during the construction process.

[0013] Furthermore, the optical zoom lens of this application supports gimbal control, enabling 360° horizontal rotation and a vertical tilt angle between -20° and 90°, thus solving the problems of existing devices lacking gimbal control and vertical angle adjustment. Simultaneously, the AI ​​camera device of this application integrates an AI computing chip, allowing its AI analysis and automated linkage control to be completed locally without relying on networks or servers, thus broadening its applicability to various scenarios.

[0014] In addition, the AI ​​surveillance camera provided in this application can perform automated monitoring and tracking, achieving the effects of cost reduction and efficiency improvement, safety supervision, and event traceability, thereby ensuring that construction sites can achieve construction supervision, process traceability, and also reduce the use of human resources.

[0016] Figure 2 is a schematic diagram of the structure of the optical zoom lens and the fixed focus lens according to an embodiment of this application. Detailed Implementation

[0017] The present application will be further described in detail below with reference to Figures 1-2.

[0018] This application discloses an automated linkage method for a panoramic AI camera. Referring to Figures 1 and 2, in this embodiment, the automated linkage method includes the following steps: S1, after the panoramic AI camera is powered on, the upper optical zoom lens and the four lower fixed-focus lenses automatically begin real-time monitoring and recording, as well as performing real-time AI analysis. The upper optical zoom lens is used to track and zoom in to capture distant details; the four lower fixed-focus lenses are used for panoramic monitoring and recording from all four sides.

[0019] S2. When no one appears in the real-time analysis screen and the duration is cumulatively 5 minutes, push an alarm message to the platform indicating that no one is present for an extended period of time.

[0020] S3. When a person enters the effective shooting range of the camera equipment, the panoramic view composed of the four fixed-focus lenses located at the bottom will capture the human figure. At this time, AI real-time analysis will automatically calculate which fixed-focus lens the human figure appears in. Specifically, the four fixed-focus lenses at the bottom are located in the front, back, left, and rear directions, respectively. The four fixed-focus lenses can form a 360° panoramic monitoring recording and have AI analysis capabilities, including human figure detection and analysis, so as to accurately capture the pixels of the human figure appearing in front of the lens.

[0021] S4. Then calculate the x and y axis positions of the human figure outline pixel area in the image. Based on the horizontal 360° circle and the vertical 180°, calculate the orientation of the human figure, thereby controlling the optical zoom lens located above to rotate to the corresponding orientation for zoom detail shooting.

[0022] S5. Once the optical zoom lens locks onto a human figure, the AI ​​analysis will calculate the position of the human figure in the frame in real time, thereby calculating the angle that the gimbal needs to rotate. This enables automated linkage control of the gimbal, which in turn drives the optical zoom lens to turn to the corresponding angle to achieve automatic tracking and shooting of the person.

[0023] Specifically, the optical zoom lens located at the top automatically analyzes the person's position in real time and then automatically coordinates the gimbal rotation. When the person is crouching or climbing a ladder, the gimbal's vertical angle is automatically controlled for tracking and shooting. When the person occupies a small percentage of the pixels in the overall shot, the lens is automatically controlled to perform optical zoom to achieve automatic tracking and shooting.

[0024] More specifically, the optical zoom lens located at the top supports gimbal control, enabling 360° horizontal rotation and a vertical tilt angle between -20° and 90°, and possesses AI analysis capabilities. This allows for 360° panoramic environmental monitoring of construction sites, automatic zoom monitoring of personnel operations, and real-time AI analysis of the entire site. It also addresses the limitations of existing equipment in terms of gimbal control and vertical angle adjustment. Preferably, the 360° horizontal rotation and vertical tilt angle movement of the optical zoom lens are driven by two separate rotary motors.

[0025] Furthermore, in this embodiment, the panoramic AI camera integrates an AI computing chip, enabling it to perform AI analysis and automated linkage control locally without relying on networks or servers, thus broadening its applicability across various scenarios. Specifically, the AI ​​analysis includes AI recognition and analysis capabilities such as human detection, face recognition, safety helmet detection, and safety reflective vest detection.

[0026] In addition, the panoramic AI camera is equipped with components such as a storage TF card, a control motherboard, a network chip, and a Beidou positioning chip, which have storage, control, and positioning functions, enabling automated linkage control. It is also equipped with a night vision infrared fill light, which allows the panoramic AI camera to maintain a stable lighting effect at night or in other adverse weather conditions, thereby ensuring clear monitoring images.

[0027] Therefore, the proposed solution can solve the problems of 360° panoramic environmental monitoring of the construction site, automatic zoom monitoring of personnel operation details, and real-time AI analysis of the entire site with a single device. At the same time, the solution of panoramic + gimbal automated linkage solves the problems of monitoring blind spots in low-lying and high-altitude areas and the inability to automatically track and zoom. On-site operators only need to set up the equipment once to solve the problem of personnel frequently moving equipment or adjusting the camera angle during construction.

[0028] In addition, the AI ​​surveillance camera provided in this application can perform automated monitoring and tracking, achieving the effects of cost reduction and efficiency improvement, safety supervision, and event traceability, thereby ensuring that construction sites can achieve construction supervision, process traceability, and also reduce the use of human resources.
