Nowadays, people rely on vehicles for travel, as cars are convenient, time‑saving and labour‑saving. They have become a means of transportation widely used in many fields of social and economic life. With continuous technological progress, requirements for automobiles in all aspects have become increasingly stringent. Cars are no longer merely simple travel tools. This trend has further promoted the development of new automotive technologies. Apart from the research and improvement of internal software systems, the exterior shapes of automobiles have continuously adopted new designs in every era. This represents the development of automotive aesthetics, leading to today’s diverse vehicle types and specifications. A client of an automobile company needs to perform scanning inspection on car roofs to acquire data, which can be applied to R&D, design comparison and modification work.

1. The car roof features a complex curved surface and a large‑size body. The client needs to scan the object quickly to generate data rapidly while maintaining high accuracy.

2. Conventional scanners have a small scanning range, are time‑consuming in operation, require lengthy data‑processing time, and fail to meet accuracy requirements.

       After understanding the client's requirements, engineers from Holon 3D decided to adopt the HL‑scan 3D scanning system. When demonstrating workpiece scanning to the client, the system displays data in real time. It can perform scanning without surface treatment on objects. Boasting a large scanning range, it is well‑suited for large‑sized workpieces with short scanning time. It can also work in conjunction with a robotic arm for scanning, which reduces manual intervention, saves labor costs and improves work efficiency. Furthermore, it delivers high scanning accuracy. The processed scanning data fully meets the client’s requirements, leaving the client highly satisfied.
