1. What is Infrared Detection Technology?

Infrared detection technology is a military reconnaissance technology that uses infrared detection instruments to find and locate targets. According to different infrared radiation sources, infrared detection can be divided into active infrared detection and passive infrared detection.

Active infrared detection emits infrared signals (usually near-infrared) to illuminate the scene, and then uses a receiver to sense the reflected infrared radiation from the environment and generate an image. This technology has the characteristics of good observation effect, high target brightness, large field contrast, clear imaging, etc., but has a relatively narrow detection range, is easily interfered with strong light sources, and may easily expose the detection location. When organizing reconnaissance, it is usually necessary to use other means for long-distance search to find targets before using active infrared night vision devices for identification at close range.

Passive infrared detection does not actively emit infrared signals but passively receives the infrared radiation emitted by target objects (usually mid-to-long wave infrared) and converts it into electrical signals to generate required thermal images. People can obtain target characteristic information based on thermal images. Passive infrared detection has the characteristics of not relying on infrared light sources or daylight, good concealment, little impact by weather conditions, etc., but has relatively blurred imaging and low resolution for distinguishing details.

2. Application of Infrared Detection Technology in Intelligent Driving

In intelligent driving of automobiles, active and passive infrared detection systems are typically used to enhance vehicle perception and safety. These two systems play different roles in different aspects:

● Active Infrared Detection:

Driver fatigue monitoring: Active infrared detection technology can monitor the facial features and behaviors of the driver to detect whether the driver is driving tired. If fatigue driving is detected, the system will issue an alert to remind the driver to rest.

Passenger monitoring: Active infrared detection technology can monitor the condition of passengers in the vehicle, such as whether someone is not wearing a seatbelt, whether someone is sleeping in the vehicle, etc.

Vehicle intrusion detection: Active infrared detection technology can be used to detect whether the vehicle has been intruded or illegally opened, and trigger an alarm or automatic alarm if necessary.

● Passive Infrared Detection:

Nighttime driving assistance: Passive infrared detection technology is not affected by visible light, and can accurately identify life signs regardless of day or night. With the advantage of anti-glare interference, it can greatly improve nighttime driving safety.
Extreme weather driving: Passive infrared detection technology can also clearly image humans, animals, and objects under adverse lighting conditions such as dust, fog, rain, snow, and nighttime. It is also well-suited for applications in mining operations such as mines.
In-car temperature detection: Passive infrared detection technology can identify temperature distribution and differences in different locations within the vehicle cabin to achieve more precise temperature control.
Expandable health monitoring function: In the future, passive infrared detection technology may provide assistance in the health direction of in-vehicle cockpits. By using thermal imaging technology, it can collect the body surface temperature of the driver or passenger to provide prompts for symptoms such as fever.

The application of infrared detection technology in automobiles can effectively improve driving safety in adverse weather conditions and reduce the occurrence of traffic accidents. The application of infrared detection technology can effectively弥补the shortcomings of existing "radar + camera" fusion perception systems, helping to promote the intelligent development of the automotive industry.
