Vizum, a company specializing in artificial intelligence technologies, has developed a custom stereo vision system for China’s first high-precision magnetic levitation (maglev) pipeline inspection robot, supporting the country’s growing demand for intelligent infrastructure monitoring.

In response to the limitations of traditional manual inspection—characterized by low efficiency, high labor costs, and limited precision—Vizum leveraged its proprietary stereo vision technology to develop a solution capable of real-time rail inspection. The system is one of many tailored smart solutions the company has delivered across industries in recent years.

As rail transportation in China continues to expand rapidly, so too does the need for accurate, high-speed, and automated inspection systems. Vizum’s rail inspection solution addresses critical operational demands, including measurements of track geometry such as gauge, superelevation, and level. Using stereo vision technology integrated with customized software, the system achieves real-time online inspection with sub-millimeter accuracy. This marks a significant step forward in the intelligent, data-driven management of railway infrastructure and contributes to filling a technological gap in domestic dynamic maglev inspection capabilities.

The system features Vizum’s proprietary stereo vision technology, capable of generating 3D point cloud data in real time at the edge. It supports low-latency, high-speed inspection and is adaptable to a variety of rail environments. With advanced optical design, it remains highly accurate in harsh lighting and environmental conditions, ensuring reliable field performance.

Operating at speeds up to 30 km/h, the intelligent inspection system delivers sub-millimeter precision—boosting efficiency by more than 20 times compared to manual inspection. It also integrates data acquisition, processing, and analysis, enabling dynamic and intelligent inspection. The system optimizes inspection workflows across multiple dimensions, significantly improving productivity and reducing labor demands.

In addition to advancing the state of domestic track detection technology, the system opens up new possibilities for intelligent inspection in applications such as tunnels, subways, power equipment, and large-scale pipelines.

The solution, fully customized by Vizum, integrates hardware, algorithms, and data management to meet project requirements for precision, traceability, and real-time performance. The company also provides strong technical support and after-sales service to ensure sustainable operation of the system.

With a focus on both product performance and the scalability of its technologies, Vizum remains committed to developing sustainable, industry-driven smart solutions.
