Development Status and Trends of Road Surveillance Cameras

Looking at the development of the industry, with the continuous improvement of intelligent transportation technology, high-speed cameras have important applications in them, making great contributions to intelligent traffic systems that can obtain clear images. It can be said that obtaining high-speed and high-definition industrial cameras helps the intelligent transportation to become even more powerful. Similarly, in the application of intelligent monitoring systems, road surveillance cameras are indispensable.

Industrial cameras help intelligent transportation

With the development of electronic technology, computer technology, micro-processing technology, and new sensors and large-capacity storage technologies, the shooting speed of high-speed and high-definition industrial cameras has greatly increased. Intelligent high-speed high-definition industrial cameras have become the mainstream devices in the field of security monitoring with their advantages of high efficiency, intelligence, and clear and stable pictures.

In the intelligent traffic system, the industrial camera collects the captured target information, converts it into digital information through the sensor, and then passes it to the image acquisition card at the IPC. It is responsible for the interface interaction with the control software, and finally produces clear image data. . The data in the image acquisition card is further transferred to the IPC memory through the IPC bus. Through the control software module, the collected data can be persistent on the hard disk of the IPC, thus forming an intelligent traffic management system system.

Vehicle speed measurement and driver's driving behavior imaging are all involved in intelligent transportation. If ordinary camera technology is used to capture high-speed vehicles, they will encounter many technical difficulties and have certain limitations. For example: the precise synchronization problem of detection, monitoring, high-speed imaging problems of intelligent transportation, and so on. When the vehicle speed reaches a certain level, the image is not clear and the license plate information is more serious. At the same time, when the light is not good, it is difficult for ordinary cameras to obtain clear images. Therefore, the use of high-speed cameras for imaging in the intelligent transportation field is an inevitable choice.

In the entire intelligent transportation system, the high-speed camera not only can clearly obtain the image of the measured moving target, but also can measure the motion parameters of the moving target more accurately, which largely overcomes the limitations and deficiencies of ordinary cameras. Therefore, the high-speed camera not only captures the high-speed traveling process of the car, but also effectively solves the imaging problems in the environment such as night or cloudy days, and truly realizes all-weather road monitoring.

Development Status of Road Surveillance Cameras

With the rapid development of the global economy, the scale of road construction continues to increase, the number of motorized vehicles and drivers continues to grow, and traditional methods of traffic management will not be able to meet the increasing traffic demand. Under this premise, the intelligent transportation system is strongly promoted and developed. It will effectively improve the level of urban traffic management and improve the efficiency of traffic management personnel. Since the 1960s, developed countries such as the United States, Europe, and Japan have begun the research and application of intelligent transportation systems. Since the early 1990s, China has gradually promoted and used intelligent transportation systems in some large and medium-sized cities. After about 20 years, Development, system construction has begun to take shape, and has achieved good social benefits.

In the intelligent transportation system, collecting, transmitting, and summarizing the relevant feature information of the target object on the traffic road is the most important step. Only when enough information is collected can the system's analysis and decision-making, plan generation, and automatic control be conducted. Other intelligent processing methods provide a true and effective data foundation. In a total source of information, video images are the most intuitive and effective information, just like the human visual system. In order to be clearer and more accurate in a variety of complex road environments, this requires a good “eye”. Road surveillance cameras are such a specialized “eye” and its importance is self-evident. The "performance of the eyes" performance will directly affect the use of the entire system.

Introduction of Road Surveillance Camera As a video image signal acquisition device, the road surveillance camera is specially used to monitor target objects such as vehicles, drivers, pedestrians, and markers in the traffic on the road, and it is required to run all the time without interruption and in real time. Clearly captures the target object's feature information (such as number plate, color, face, outline, shape, etc.). As the use environment is relatively complex, harsh and unpredictable, the design, production and manufacture of road surveillance cameras must comply with industrial standards.

Road Surveillance Camera Development Trend

Along with the development of the domestic intelligent transportation industry, the application of road surveillance cameras in the transportation sector has further deepened and continues to play a major role. In order to use effectively in various complicated road environments, the quality of the captured video images is clearer and more accurate, and the performance requirements for road surveillance cameras are getting higher and higher, and the product form is also more specialized and serialized. In recent years, new high-tech products such as high-definition cameras, infrared cameras, automatic tracking cameras, network cameras, high-light suppression cameras, and wide dynamic cameras have been introduced in accordance with various application requirements.

The main function of the road surveillance camera in the intelligent traffic system is to collect the video image signal, and transmit the image signal through the transmission line to the signal acquisition host for image storage, analysis and processing. The main applications are summarized as follows: Road conditions monitoring The front-end camera transmits the real-time image of the monitored area to the traffic command center via the transmission line, and the traffic commander grasps the traffic conditions of the intersections and road sections in real time. For example: traffic flow and signal status of the road section. , violations of motor vehicles and traffic accidents. This information can help the traffic management department to take appropriate measures and handle the plan in a timely manner. It can promptly publish information through the broadcast television media and the forward traffic guidance display screen to inform drivers and pedestrians on the road for effective traffic guidance.

Conclusion:

With the continuous development of society, the market demand for high-speed cameras has become more and more extensive, and various industries have applied to different degrees in the industrial field. It is believed that in the next few years, smart high-definition high-speed industrial cameras will eventually become indispensable assistants in people's daily lives and work, providing more complete protection for urban security.
