Xiaomi’s new-generation SU7 was officially launched on March 19. Among the many highlighted upgrades, one core principle is repeatedly emphasized: safety is the foundation and the prerequisite—above everything else, with no compromise.
From a body structure made of 2200 MPa ultra-high-strength steel to a 17-layer battery protection system; from LiDAR as standard across all models to a triple-response structural design—the upgrades in the new SU7 go beyond feature enhancements. They represent a systematic strengthening of overall vehicle safety under the philosophy that “safety comes first” in modern automotive manufacturing.
However, a more fundamental question arises: how are these safety commitments truly delivered in manufacturing?
The answer lies in pushing the limits of assurance through 3D inspection.
Behind the Safety Upgrade: A Comprehensive Leap in Manufacturing
The upgrades in the new SU7 essentially impose higher demands on manufacturing:
- Silicon carbide high-voltage platform → higher requirements for battery system precision and assembly consistency
- Body strength increased to 2200 MPa → more complex deformation control challenges
- Complex integrated die-casting structures → greater difficulty in controlling dimensional variation of large components
- Full standardization of intelligent driving hardware → vehicle assembly precision directly affects sensor performance
Among these changes, the battery tray and the integrated die-cast rear floor have become the most critical and challenging core components.
Under the new SU7’s high-voltage platform and multi-layer safety protection system, the battery tray is no longer just a supporting structure—it directly contributes to vehicle rigidity and safety performance. It features multiple threaded holes, mounting surfaces, and sealing surfaces, while also being a large thin-walled structure prone to deformation. This places extremely high demands on assembly precision. Even slight deviations can affect sealing, structural strength, and even thermal safety, making EV battery inspection essential.
At the same time, the ultra-large integrated die-cast rear floor introduces further challenges in overall precision control. Reflective materials and machined holes increase measurement interference, while fast production line cycles require inspection to keep pace. Under real-world production conditions—high temperatures, vibrations, and changing lighting—achieving stable and accurate inline inspection becomes a shared challenge for both components and overall quality control.
Automated 3D Measurement
Making Safety Visible
To address these challenges in the SU7’s key structural components, advanced automated blue-light 3D scanning and 3D inspection solutions enable comprehensive upgrades in manufacturing and quality control—achieving a full closed loop from data acquisition to quality assurance.
01 High-Efficiency Data Acquisition
The system uses non-contact optical measurement, powered by PowerScan sensors. With multi-view matching and optimization algorithms, along with CPU/GPU dual-engine acceleration, it effectively reduces interference from reflective and absorbent materials, ensuring high-quality point cloud data even under complex surface conditions.
A dual-robot collaborative scanning mechanism allows flexible coverage of deep cavities, undersides, and blind spots. Single scan time can reach as fast as 0.2 seconds, meeting production cycle requirements while supporting efficient 3D scanning and inspection.
02 Intelligent Reconstruction with Proprietary Algorithms
For data processing and reconstruction, VisionInspect software enables both marker-based and markerless intelligent stitching. Using feature matching, point cloud alignment, ICP optimization, and global constraints, it achieves multi-view data fusion and precise 3D reconstruction, ensuring accurate 3D inspection results.
03 Fully Automated Workflow
The entire process—from automated loading, scanning, CAD alignment, deviation analysis, to report generation—is fully automated. Key dimensions are visualized and traceable, enabling a transition from traditional sampling inspection to full-field, inline inspection, and improving overall quality control.
04 Stable Online Operation
With environmental adaptations such as humidity control, light shielding, and vibration-resistant foundations, the system can operate reliably under real production conditions, including temperature fluctuations, vibrations, and lighting changes. This ensures stable and continuous 3D inspection in industrial environments.
From Safety Promise to Manufacturing Reality
The new Xiaomi SU7 emphasizes not just leading specifications, but also continuous reinforcement of safety as a baseline. In this journey, 3D inspection is no longer just the final checkpoint—it is embedded throughout the entire manufacturing process.
From battery trays to integrated die-cast rear floors, from point inspection to full-dimensional data-driven quality control, advanced 3D scanning and inspection technologies provide stable and reliable quality assurance for the SU7’s critical structural components within modern automotive manufacturing.
