Defogging zoom lens is a technology that penetrates haze and can penetrate haze in haze weather, obtain clear images and videos, and reduce the impact of bad weather. Generally speaking, defogging can be divided into electronic defogging (algorithmudgement) and optical defogging (physical defogging). The former uses visible light to repair images through algorithms; while the latter uses lenses to penetrate near-infrared light to improve the clarity of the image in haze weather.
Whether it is algorithm-based electronic defog or optical defog based on penetrating near-infrared light, there are many disadvantages such as image loss and high cost. However, there is a complementary relationship between electronic defog and optical defog.
Against the background of the above-mentioned seemingly "complementary" technology, a new defog removal technology - "electronic + optical double defog removal" came into being. Haze penetration technology has quietly emerged. Its essence is to improve penetration effect through integrated optical defog removal. Different companies use different technologies and effects.
As the security industry evolves from passive defense to active defense, "electronics + optical double fogging" has become the mainstream defogging technology at present. Various manufacturers have launched corresponding defog camera products. At present, all our products with a focal length of more than 200mm have adopted "electronic + optical double defog".
Application of defogging technology in the video surveillance industry
It should be noted here that the original intention of haze penetration technology is not just to penetrate haze.
In fact, the original intention of haze penetration technology is to solve the video problem under low visibility conditions (such as rain, fog, haze, dust, sand, strong light, backlight, etc.). However, since haze is more common in these weathers, it is called defogging technology. In other words, the essence of defogging technology is to solve the problem of low visibility of video surveillance equipment and improve its visual distance and video clarity under low visibility. At the same time, we have designed strong light suppression technology to provide clear and high-quality video in various harsh environments.
Judging from the current situation, highways or transportation are the most widely used scenarios for defogging technology, and have derived many traffic safety monitoring systems. In foggy days, defogging technology is a comprehensive monitoring system based on video presentation and aims to ensure safe driving in harsh environments. It can automatically monitor and collect information such as road conditions, road environment, abnormal events, traffic conditions and other information in real time to improve driving safety.
Huanyu visual defogging technology can be applied to high-point monitoring, forest fire prevention, shipping/maritime operations, highways, railways, airports, ports, border defense, squares, scenic spots, stations, large venues, community surroundings and other monitoring places. With the continuous advancement of chip computing speed technology, the defog removal system can cooperate extensively with various video systems such as security, emergency management, firefighting, individual combat, robots, aviation and drones, active safety assisted driving and future unmanned driving, handheld equipment (mobile phones), AI glasses and other industries. It can not only bring new ideas to security and traffic safety, but also bring a revolutionary era to all walks of life.
Based on defogging technology, a large number of hardware products have emerged on the market, including optical lenses, professional algorithm modules, various signal transmission hardware and special chips. It can provide different solutions for many fields such as fire rescue solutions, landslide rescue solutions, intelligent tourism monitoring solutions, environmentally friendly intelligent monitoring solutions, road icing warnings and solutions. The launch of these products and solutions has brought more possibilities to defogging technology in areas such as safe production, transportation, security and rescue in low-virtual weather.
