The characteristic of thermal radiation allows people to use the infrared thermographic camera for non-contact temperature measurement and thermal analysis of objects, which can be displayed in various ways. For example, by performing pseudo-color processing on video signals, different temperature thermal images can be displayed in different colors; by performing analog-to-digital conversion processing on reverse video signals, the temperature values of each point on the object can be displayed numerically, making visible what the human eye cannot see. Therefore, it can be said that infrared thermographic cameras increase human senses from five to six. Infrared Thermocamera can intuitively display the temperature field on the surface of an object, unaffected by strong light, and are widely used. The biggest advantage of thermal imaging technology is that it can avoid the influence of smoke, rain, snow, and light, completing clear and interference-free monitoring work.

To achieve a smart city, it cannot be achieved overnight. Each system is an open system, which continuously adds features, gradually improves, and constantly upgrades. "Smart cities" need to have four major characteristics: comprehensive and thorough perception, broadband pervasive interconnection, intelligent integrated applications, and people-oriented sustainable innovation.

The basis of infrared thermographic camera is all objects in nature with temperatures higher than absolute zero

Passive infrared night vision technology evolved from the concept of reflecting infrared rays that carry the object's characteristic information continually. Incorporating this technology, the thermal camera manufacturer has created an industrial thermal camera that allows for monitoring and comprehensive perception of various aspects of urban management through sensing capabilities. With real-time intelligent recognition and 3D perception of the city environment, these cameras capture information on location changes, state, and other details in an all-encompassing manner. This feature-rich technology provides surveillance solutions to achieve a better, safer, and more efficient environment for all.

Application of infrared thermographic camera in intelligent transportation

In the field of intelligent transportation, besides identifying the actual number of passengers on a vehicle, the infrared thermographic camera can also be applied to intersection control and monitoring and detection of narrow alleys. The core is to use video image processing software, often used in conjunction with perimeter intrusion detectors. IR thermal scanner can also greatly reduce the risk of night driving. It allows drivers to see further and with higher clarity than when using standard headlights. Drivers can detect and monitor pedestrians, animals, or objects on or near the road, giving them more time to react to any potential danger.

Currently, as unmanned driving becomes increasingly popular, industrial thermal camera is applied as on-board equipment for assisting driving. Its vision distance is 5 times that of headlights, which can help drivers detect roadblocks, other vehicles, turns, etc., earlier and effectively reduce the risk of night driving and avoid accidents. The Chengdu Traffic Management Bureau boldly introduced infrared thermal imaging technology to monitor the number of passengers in HOV lanes in real-time. The number of passengers on the vehicle is clearly visible from the infrared thermal image captured by the infrared thermographic camera. At the same time, ordinary cameras can capture and monitor from the front, side, and rear angles, forming a complete chain of evidence in conjunction with infrared thermographic camera monitoring.
