The main function of automobile body is to protect the driver and form a good aerodynamic environment. A good car body can not only bring better performance, but also reflect the owner's personality. The automobile body consists of engine cover, roof cover, trunk cover, fender and cowl panel. The traditional measurement method is time-consuming and laborious, and the accuracy of the measured data may not meet the requirements.

Practical problem

    It is necessary to quickly carry out three-dimensional measurement on the whole vehicle to obtain the three-dimensional digital model, but there are many curved surfaces of the whole vehicle, which are also complex. In addition to improving the measurement efficiency, the measurement accuracy should also be well controlled, and the global measurement accuracy should be controlled within 0.2mm.

Holon solutions

    According to the specific situation of the company, Hualang 3D engineers only need to use the holon3d customized 3D scanner (hl-3dwv+) to scan the car body, quickly obtain the 3D data of the tested car body, establish the car body data, and provide an important basis for subsequent production and design modification.
    The advanced and stable photographing three-dimensional scanning method can meet the requirements of rapid measurement more than any traditional measuring equipment. It can also be easily solved for the more complex situations of automobile surfaces. Finally, it can quickly obtain the complete three-dimensional information of automobile surfaces, greatly reduce the measurement time and effectively improve the work efficiency. The holon3d customized 3D scanner (hl-3dwv+) is used to scan the car body. It takes 2.5 hours and the scanning accuracy reaches 0.2mm.
