Infrared thermal imager used for road smart transportation

The awareness of traffic safety lies in the individual, but also in the society. Nowadays, domestic and foreign traffic control departments have some understanding of infrared thermal imaging cameras and are also very interested in using this technology for traffic law enforcement management at intersections, pedestrian/vehicle detection, etc.

Infrared thermal imaging cameras can present thermal images according to different temperature signals generated by pedestrians and vehicles on the road, so as to realize the detection function. The advantage of the infrared thermal imager is that it can work normally without using any light source on the road, and it will not be unable to image due to direct sunlight. Therefore, the infrared thermal imaging camera can provide 24-hour uninterrupted pedestrian and non-motor vehicle detection regardless of light or dark. When a pedestrian or vehicle enters the area, the intelligent software connected to the thermal imaging sensor will trigger the detection and transmit the signal to the traffic signal controller.

Intelligent analysis software also makes infrared thermal imaging technology even more powerful. The infrared thermal imaging camera will automatically identify the detection target. When a pedestrian or vehicle enters the area, the intelligent software connected to the thermal imaging sensor will trigger the detection and transmit the signal to the traffic signal control machine to achieve the purpose of monitoring and detection.

As we all know, when the signal light is green, pedestrians can pass and motor vehicles stop; when the light is yellow, motor vehicles are still stopped, and appropriate time is given for pedestrians to continue to pass, but in special circumstances, such as when a disabled person is crossing the road , It is necessary to extend the transit time, and the infrared thermal imaging camera can transmit the detection signal of the presence of pedestrians to the traffic signal system, thereby extending the time of yellow light and ensuring the safety of pedestrians. In addition, if the thermal imager detects that no pedestrians are crossing the road, the yellow light can also be shortened through the sensor signal, which improves the efficiency of road operation.
