In the over 40 years since the initiation of China's reform and opening-up, urbanization has made remarkable achievements, especially in the 21st century, where the pace of urbanization has accelerated, with millions of rural residents migrating to cities each year. However, with the continuous expansion of urban populations, cities are facing various challenges, commonly referred to as "urban ills," including resource shortages, environmental pollution, traffic congestion, and safety hazards.

To address these urban challenges, the concept of "Smart Cities" has emerged. Smart Cities leverage new-generation information technologies, including radio frequency sensing, Internet of Things (IoT), cloud computing, and next-generation communication technologies, to effectively mitigate urban issues. The application of these technologies allows cities to become more perceptible and their resources better integrated, enabling fine-grained and intelligent city management, thereby reducing resource consumption, lowering environmental pollution, solving traffic congestion, and enhancing safety.

Currently, urban development has transitioned from traditional digital cities to smart cities. The construction of smart cities has expanded to cover regions across the eastern, western, and central parts of China. Besides first-tier cities like Beijing, Shanghai, Guangzhou, and Shenzhen, economically developed regions such as Hangzhou, Chongqing, Xiamen, and Zhuhai have also actively undertaken smart city initiatives. Provinces such as Hubei, Hunan, Shandong, Liaoning, Sichuan, and Anhui are also actively promoting smart city projects, leading to the formation of a comprehensive "smart city cluster" across the country.

Addressing the practical demand for real-time three-dimensional mapping with large area coverage, high efficiency, and high accuracy in smart cities, Beijing Stellar-Vision Systems has introduced the WARP Omni oblique aerial camera. This product is capable of being mounted on various aircraft models, featuring low-altitude, lightweight, and large-format capabilities. The WARP Omni integrates a high-resolution industrial aerial camera, high-precision inertial navigation system, gyrostabilized platform, shielded compartment, and self-developed high-capacity controller. It can be deployed on helicopters, fixed-wing aircraft, rotary-wing aircraft, or large-scale unmanned aerial vehicles for oblique aerial photography, with minimal susceptibility to airspace, environmental, and weather conditions.

The use of WARP Omni to acquire high-quality oblique data significantly enhances the accuracy and realism of real-time three-dimensional maps in smart cities, promoting the development of oblique imaging applications and providing fundamental geographic information data for smart city initiatives.
