          Volvo truck top cover 3D scanning solution

          Volvo Truck Parts Manufacturing Co., Ltd. hopes to obtain three-dimensional sweep data of the truck top cover, and distinguish the key parts of the product from its own defects according to the high-density point cloud data of the truck top cover to ensure the processing efficiency and production quality of the truck top cover.

          Practical problems

          1. It is very cumbersome and time-consuming to use traditional methods (such as inspection tools, fixtures, three coordinates, etc.) to measure the top cover of the truck. It is not easy to accurately and quickly measure and detect the shape of the truck cover.

          2. There are many curved surfaces on the top cover of the truck. The shape of the grooves on each surface is different, and the top cover of the truck is relatively large and easy to deform. It is difficult for the general three-dimensional scanner to quickly and accurately obtain the three-dimensional digital model of the automobile bumper.

          Truck cover scanning scene

          There are many curved surfaces for the top cover of the truck, and the grooves have different shapes. Hualang 3D engineers propose solutions for use: hand-held 3D scanner HL-3DH-3M (quickly acquire high-precision 3D data from truck top cover) + reverse design software Geomagic Studio (convert truck top point cloud data to triangulation) Grid data), the secondary design of the truck roof.

          1. Preparation in the early stage:

          Spraying the developer: Improve the background color contrast of the sample surface for better scan data.

          Paste mark points: Make the acquired data be positioned and stitched in the scanning software.

          2. 3D scanning:

          Hualang 3D engineers use the handheld 3D scanner HL-3DH-3M to quickly obtain high-precision truck roof 3D data. The three-dimensional scanner has the characteristics of small size, light weight, simple operation, fast scanning, and no external AC power supply. Fast 3D scanning of the top of the car for high-density point cloud data. It takes only 30 minutes to get 3D data of the truck top cover with an accuracy of 0.07mm. Using the acquired three-dimensional data of the truck roof, it is imported into Pro/E, UG and other mainstream reverse software for post-processing, speeding up the secondary design of the truck roof, providing reliable parameters to other relevant departments, and accelerating the production of the truck roof.
