3D inspection of automobile
Cars have become a means of transportation in modern society and gradually integrated into people's lives. With the increase in demand, various requirements are also changing. Car manufacturers improve their own cars as requirements change, use 3D scanning technology to obtain the shape data of the whole car, abandon the traditional scanning measurement method, speed up the improvement of the technical staff in the design, design a better car appearance, and increase market competition force.
Practical problems
The car has large volume, many irregular contours on the surface, large arcs, and surface treatment for reflections. The overall scanning is a big project, with certain scanning difficulty.
The traditional measurement method has insufficient data collection density and cannot accurately measure the curvature of the curved surface. Moreover, the volume is large, the scanning work is time-consuming, the workload is large, the data accuracy is low, and the work cannot be completed efficiently and accurately.

solutions
The whole vehicle is large in size and it is difficult to scan. Use the handheld 3D scanner HOLONB71+ 3D photogrammetry system HL-3DP. The first step is to prepare to spray the developer to improve the contrast of the background color and follow the mark and code points. Then, three-dimensional photogrammetry is used to take multiple images of the car body. These images are automatically combined through software and then calculated to obtain the 3D coordinates of the center of each code point, and calculate the 3D coordinate values. Import the 3D coordinate data of the car body surface into the scanning system, and then use the handheld 3D scanner HOLONB71 to quickly scan to obtain high-precision 3D data. The scanning speed is fast, the data accuracy is high, and the stability is strong.
The use of the 3D photogrammetry system in conjunction with the 3D scanner improves the stitching accuracy of the overall point cloud of the 3D scanner, shortens the use time, improves work efficiency, and has higher scanning accuracy. Importing the data into the 3D software for processing and analysis solves the customer's problem. The accurate data is convenient for the customer to use in the later design improvement.
