HangzhouMay 15, 2026 /PRNewswire/ — Recently, as the Ministry of Transport’s “Mobile +” contactless passage policy continues to be implemented, applications such as highway non-stop toll collection and mobile payment have become fully widespread. The industry has set higher standards for traffic license plate recognition accuracy and full-scenario adaptability. Against this industry backdrop, Dahua Technology has officially launched the Chiguang Camera Series. Leveraging core AI large model technology to reconstruct intelligent perception capabilities, it breaks through the performance limitations of traditional equipment, achieving a dual upgrade in technological innovation and application value, injecting new momentum into the high-quality construction of domestic intelligent transportation.
As a significant achievement of Dahua Technology’s full-chain self-developed efforts in the field of intelligent perception, the Chiguang Camera Series offers all-weather, full-scenario, and highly reliable perception advantages. It encompasses two core categories: vehicle capture recognition and intelligent perception. It can precisely capture full-dimensional information features of vehicles, intelligently judge various traffic emergencies, and perfectly adapt to core scenarios such as highway gantries and toll stations, achieving the smart management goal of “seeing clearly, recognizing accurately, and managing well.”
The core breakthrough of the Chiguang Series this time lies in achieving a leapfrog upgrade from perception to cognition. The product deeply integrates AI large models with visual perception technology, building a full-process cognitive system of “prediction – analysis – management,” comprehensively enhancing the refined management efficiency of people, vehicles, objects, and various events in traffic scenarios. Targeting industry pain points such as blurred license plates, similar characters, occlusion and stains, and difficulty in recognition under adverse weather like rain, snow, and fog on highways, the Chiguang capture camera innovatively adopts a large and small model collaborative architecture: the small model enables fast and efficient vehicle detection, while the AI large model accurately verifies blurred characters and corrects color-shifted images. Combined with a professional protective structure and AI ISP technology, it significantly improves vehicle capture rates and license plate recognition accuracy in core highway scenarios.
According to real-world test data from multiple highways in Zhejiang and Henan provinces, the Chiguang camera achieves a vehicle capture and license plate recognition rate of over 99.92% in gantry scenarios and over 99.91% in toll station scenarios, laying a solid data foundation for all-weather intelligent highway operations with hard data.
In terms of hardware and environmental adaptation, the Dahua Chiguang Series innovatively breaks through environmental constraints, reshaping highway traffic operation efficiency. The product is equipped with a retractable sunshade, a 15° tilted glass cover, and a self-cleaning anti-condensation glass to form a professional physical optical barrier. Supplemented by an intelligent temperature control system and self-developed AI algorithms, it actively resists interference from rain and fog condensation, strong light overexposure, and extreme temperature differences, stably outputting high-definition images. This not only effectively reduces recognition failures, road congestion, and manual maintenance costs caused by adverse weather but also significantly improves traffic efficiency at toll stations and gantries, providing solid hardware support for cost reduction and efficiency improvement on highways.
At the same time, relying on large and small model collaborative algorithms, full-field detection, and deep learning technology, the Chiguang Series can precisely overcome challenges such as dirty or blurred license plates, occlusion by front and rear vehicles, and strong light interference from bull’s-eye lights, achieving pixel-level image restoration. On one hand, it effectively reduces highway billing disputes, curbs toll evasion, ensures full traceability of traffic data, and improves audit management efficiency. On the other hand, it provides reliable data support for core businesses such as road network traffic flow analysis and toll revenue distribution, solidifying the trust foundation for compliant intelligent transportation operations.
Aligned with the development trend of the Ministry of Transport’s “Mobile +” contactless passage policy, the Chiguang Camera Series, with its ultra-high recognition accuracy, provides underlying technical support for non-stop highway lane passage and the popularization of mobile payment, fully enabling the implementation of contactless passage value-added services. Additionally, the product features a built-in multi-in-one perception module, flexibly adapting to the long-term upgrade needs of smart highways and fully compatible with next-generation transportation systems such as free-flow tolling, holographic road networks, and vehicle-road-cloud collaboration, helping the transportation industry avoid redundant investments and build differentiated competitive advantages.
From hardware innovation to AI empowerment, from passive recognition to active cognition, the Dahua Chiguang Camera Series is not just an iteration of product technology but a qualitative leap in intelligent transportation perception from “seeing” to “understanding.” In the future, Dahua Technology will continue to deeply cultivate the intelligent transportation perception track, deeply integrating AI large model technology with industry application needs, using full-dimensional innovation to support the digital reform of highways and continuously empower the digital and intelligent transformation of transportation.
