What Are the Applications of Infrared Thermal Imaging Technology in Security Robots?

With the development of cutting-edge technologies such as big data, artificial intelligence, and the Internet of Things, more and more technological equipment has been popularized. As intelligent high-tech equipment, security robots are effective in assisting police on duty, intelligent security, and convenience services, and play an important role in the field of public safety.

The application of infrared thermal imaging technology has greatly improved the practical application of security robots in special scenarios. The system composition and technical implementation plan are as follows:

The security robot infrared thermal imaging system platform includes thermal imaging data aggregation, analysis and processing, and abnormal information push. It involves intelligent analysis of video data. Based on the analysis algorithm, the uploaded data is analyzed and compared through preset thresholds. If the overflow is handled, an early warning prompt of abnormal data will be generated. The threshold range can be adjusted according to the needs of the relevant parts of the algorithm.

Wireless communication provides a connection channel for real-time upload of data transmission and instruction issuance for the infrared thermal imaging system platform and front-end equipment. The data is pushed to the security robot infrared thermal imaging system platform through the wireless communication network. The thermal imaging video data and abnormal conditions are pushed to the portable terminal to realize the data sharing and intercommunication between the platform and the front end, and the front end and the receiving terminal.

As an on-site data viewing and alarm receiving device, the portable terminal can perform real-time remote control of the security robot, receive infrared thermal imaging videos pushed by the security robot, and display abnormal situations in real-time to achieve accurate and rapid identification and disposal.

In order to ensure the real-time and stable push of the data collected by the security robot on-site, and to realize the millisecond-level response situation of abnormal situation information, the front-end collected on-site data is simultaneously pushed in both directions. On the one hand, it is pushed to the infrared thermal imaging system platform through the wireless communication network, and the collected images are compared and judged with the information in the human body shape database.

During the patrol process, the security robot's infrared thermal imaging system can perform human body capture and identification functions, including human intrusion alarm, cross-border alarm, and legacy alarm.

Among them, the position of the edge of the patrol area can be specified in advance for the intrusion alarm; the position and direction of the boundary can be specified in advance for the cross-border alarm; the threshold for the retention time can be specified in advance for the detention alarm.

During the movement of the security robot, it detects and locates the human body appearing in the infrared imaging video stream in real-time, and outputs the position of the human body (location frame) in the video. When the human body recognition alarm is triggered, the robot stops moving, and the security robot infrared thermal imaging.

The system platform pops up the human body recognition alarm pop-up window, and the infrared thermal imaging system platform sends the human body recognition alarm information to the portable terminal near the security robot. After the security personnel receives the information, they will determine the suspicious person. When the infrared thermal imaging system platform turns off the alarm, the robot will continue to perform tasks. If no one clicks to close the alarm dialog in the background, the alarm will not stop automatically.

The collected data is first stored in the local NVR and then pushed to the security robot infrared thermal imaging system platform through the security access module through the wireless communication network.

On the one hand, use image data processing software and call algorithm functions to compare and judge data parameters; on the other hand, process the input original parameters to extract basic features in the data, such as corners, edges, textures, lines, boundary, etc., using a gradient optimization algorithm, standard particle swarm algorithm, linear sampling, and other algorithms to perform a numerical calculation on the data collected by the front end, forming a machine vision expert database of typical human body characteristics, which is used for later data analysis and comparison.

On the one hand, the security robot portable terminal warning information receiving solution can receive warning information from the infrared thermal imaging system platform; on the other hand, it can also directly view the security robot's infrared thermal imaging real-time video. In the mission area of the security robot, you can receive real-time warning information of emergencies in the monitoring area through the portable terminal, check the actual situation in the monitoring area in time, and realize rapid response to abnormal situations.

When performing regional night patrol tasks, suddenly intruding into abnormal personnel, the robot will trigger an early warning and feedback the abnormal information to the portable terminal APP, and the warning information will pop up to prompt the security personnel to deal with the abnormal situation in time, so as to ensure the nighttime safety of the patrol area in real-time.

The security robot has the infrared detection area intrusion function, which can monitor emergencies in the designated area in real-time. When an abnormal person is found during a night patrol in a certain area, the security robot will trigger an early warning and feedback the abnormal information to the system platform, and the platform will pop up a warning message Prompt the security personnel to deal with the abnormality in time and ensure the nighttime safety of the patrol area in real-time.

In harsh weather conditions such as rain, snow, and fog, the observation effect of the visible light system is poor and cannot work normally, while the infrared wavelength is longer and the ability to penetrate rain, snow and fog is high, and the security robot can use infrared thermal imaging. Detection technology to overcome patrol and surveillance at night or in harsh environments.

Some outdoor scenes are complex and changeable, making it more difficult for security personnel to control the area. Especially in the grass and woods around major activity areas, the phenomenon of hiding suspicious persons often occurs, and the specific conditions on the site cannot pass conventional detection equipment.

However, the temperature characteristic information of objects such as plants and buildings is much lower than that of the human body. When the infrared thermal imaging system passively receives the thermal radiation signal, the misjudgment of the human body characteristic information is difficult to occur. However, when the bushes are too thick to completely block the suspicious target, it is difficult to effectively identify the suspicious target using infrared thermal imaging technology.

In addition, the infrared thermal imaging system can effectively filter the interference of complex structures, light and object shadows in the environmental background, and will not misjudge the above interference factors as targets. The safety protection efficiency of the on-duty security robot has been improved.

Since the infrared thermal imaging system reflects the temperature of the object, it determines whether there is an abnormal fire source by determining the highest temperature in the field of view. When a high-temperature point is detected, a security alarm will be triggered immediately, a siren will sound, and at the same time, the background will be linked and a fire alarm pop-up window will pop up on the background client.

The application of infrared thermal imaging technology in security robots solves the problem of unclear identification of security robots when performing patrol duties at night, and can achieve accurate identification, automatic early warning, and rapid response to abnormal situations under limited police force conditions. It improves the actual combat performance of the security robot and provides effective technical support and safety guarantee for the security robot in the actual combat application.
