As traffic management systems advance towards greater intelligence, the demand for higher image quality in road monitoring and related application scenarios continues to grow. High-speed global shutter cameras, with their exceptional image capture capabilities and high precision, are widely used in road monitoring.

1. Understanding High-Speed Global Shutter Cameras

High-speed global shutter cameras use global exposure technology, enabling all pixels on the image sensor to be exposed simultaneously while capturing the entire image in one instant. This differs from traditional rolling shutter cameras, which expose the image line by line or in segments. By employing global exposure, these cameras effectively eliminates the image distortion often seen in rolling shutter systems when capturing fast-moving objects, giving high-speed global shutter cameras a distinct advantage in such scenarios.

2. Selecting a Camera for Road Monitoring Scenarios

Choosing the right high-speed global shutter camera for road monitoring involves consideration of several critical factors:

• Sensor:The image sensor is the core component of a global shutter camera, responsible for converting light into electronic signals to generate the image. The choice of sensor directly affects image quality. When selecting a sensor, opting for a larger one is often beneficial. Larger sensors have a larger light-sensitive area, allowing them to capture more photons under the same conditions. This improves the signal-to-noise ratio, reduces noise, and results in clearer images with more natural colors.
• Shutter Speed:A fast shutter speed is crucial for reducing motion blur, especially when capturing fast-moving vehicles. In road monitoring, only a sufficiently fast shutter speed can ensure that clear images are captured as vehicles quickly pass by.

• Resolution: Resolution is a keyfactor in determining the ability of a camera to capture fine details. In road monitoring systems, high-resolution cameras can capture more intricate details, making it easier to accurately analyze and assess of road conditions.

• Frame Rate: Frame rate refers to the number of frames a camera can capture per second. In road monitoring, a high frame rate above 30fps ensures smooth, continuous image data, which is essential for real-time monitoring of road conditions. To maintain stable video streams and minimize bandwidth requirements, road monitoring systems require cameras to output high-frame-rate video, encoded in H.264 or H.265 formats, to ensure stable video streams while reducing bandwidth demands. This helps meet the network transmission and storage requirements in practical applications.
• All-Weather Monitoring: The camera should be equipped with an excellent ISP (Image Signal Processor) to ensure image quality and automatic adjustments for common weather conditions, such as daylight, overcast skies, rain, or snow.
• Protection Rating: Since road monitoring cameras are typically installed outdoors, they must be capable of withstanding exposure to sunlight and harsh weather conditions. Therefore, the camera should feature efficient heat dissipation and robust waterproofing.
• Interfaces and Compatibility: It is crucial to ensure that the camera is compatible with both the software and hardware of the system, enabling seamless integration of interfaces and protocols.
• Software Support: Depending on the product type, there are generally two categories:

A high-speed global shutter camera at the front end sends images to a PC, where the software processes the road monitoring and outputs results.

The algorithm module is directly integrated into the high-speed global shutter camera, enabling the camera to output monitoring results directly.
