With the advancement of science and technology and the rapid development of urban construction, transportation construction has been continuously expanded, and the traffic volume has also increased rapidly, but it is accompanied by road congestion, frequent traffic accidents, and an increase in sudden cases. It is almost impossible to expand with limited traffic management human resources to meet the needs of traffic intelligence in the monitoringsystem. Therefore, we can only use more convenient and intelligent technical tools to strengthen traffic management and safety precautions. The high speed and high performance of industrial cameras have become the mainstream equipment for intelligent transportation, and can capture high-definition images for it. The combination of intelligent traffic monitoring system and industrial cameras improves safety and efficiency.

Intelligent traffic monitoring application

Differences between industrial cameras and general digitalcameras

General cameras will encounter some technical problems in the image acquisition process. For example, when shooting high-speed vehicles, general cameras may cause image distortion due to excessive speed, resulting in the inability to capture the driver's face, driving behavior assessment or vehicle speed measurement, and general cameras cannot capture clear images in low light conditions. However, industrialcameras can not only clearly capture the image of the detection target, but also accurately measure the motion value of the detection target when paired with the traffic monitoring system, and capture high-speed vehicles in different environments, such as night, cloudy and rainy days. In harsh environments, it effectively overcomes the technical limitations of general cameras and makes the intelligent traffic monitoring system moreaccurate.

Application of intelligent transportation

YunYi Technology's GigE series high-dynamic cameras (black and white cameras and color cameras) provide 24x7 hours of uninterrupted all-weather monitoring, becoming the most powerful intelligent traffic monitoring tool for public security departments in various countries. The high-dynamic cameras in this series are equipped withHighly sensitive Sony Pregius CMOS sensors (IMX264/265/252/174), which can ensure high-resolution image transmission at a speed of up to 120 frames per second even in unfavorable lighting conditions. When used with traffic monitoring systems, they can accurately locate the position of the detection target and provide excellent image quality. In addition, the new Sony sensor has ultra-low noise and provides a wide range ofSNR (signal-to-noise ratio), so it can accurately capture the driver and the reflective license plate. Image capture can be synchronized with software triggers, and the built-in high-speed cache also ensures that the image is successfully transmitted. For example, when a vehicle (detection target) enters the speed radar range, the rabbit beam evaluates the driving behavior and vehicle speed and makes a judgment based on thepre-set tolerance range. If the vehicle speed exceeds the limit, the camera is triggered to capture the illegal vehicle, capture a clear close-up of the license plate, and the captured image will be transmitted to the public safety department for review and processing. In addition, built-in automatic gain, exposure control and automatic white balance functions support external event timing control and accurate exposure. C/CS interface lens,external trigger input function and external I/O input also make the camera easy to set up and integrate in the intelligent transportation system. Industrial cameras installed in intelligent transportation systems can provide continuous traffic monitoring even under adverse conditions.

In addition, this series of cameras is lightweight and struggle, small in size (29 X 29 X 34 mm), light in weight, and very easy toinstall in a small space, meeting the concept performance required by public security departments and facilitating investigation and evidence collection during the detection process. In addition, Yunkey Technology's industrial cameras are shock-resistant and have undergone long-term vibration and aging tests before leaving the factory, which can avoid image shaking during shooting. They also have locking and bending resistance characteristics, and can stabilizetransmit 100M through a Gigabit Ethernet cable, so there will be no problems with knotting or insufficient distance during the integration process of the camera.
