By a well-known car company commissioned to scan the vehicle's three-dimensional data, optimize the performance of the car. In the understanding of the actual situation, Hualang 3D technology engineers use 3D Photogrammetry System HL-3DP + 3D scanner HL-3DW, quick access to car body and wheel arch data, optimization of drag racing.
The use of traditional methods not only spend a lot of time and huge investment, can not meet the actual requirements of the team. D according to the problems faced by the team, the proposed solution used in the solution: three-dimensional Photogrammetry System (HL-3DP) + 3D scanner (HL-3DW) to obtain the car body and wheel arch data. The car gets out of the car after the appearance of manufacturing data model wind tunnel experiment, test the drag coefficient.
1, the traditional measurement method of data acquisition density is not enough (data) and the surface of the body and the curve can not be measured, can not be normal detection, the latter can not reverse the drawing. Heavy workload, low efficiency and accuracy is not high, can not reach the customer requirements.
2, scan the car body and the wheel arch, optimize the body structure, so that the car has a better flow of linear. The car body length 4.5m width 2.3m, general 3D scanner scanning format is small, large objects when the cumulative scanning area too much. Can not find the signs and splicing is not a good question. Generate a large amount of work, low efficiency, and the accuracy of the data can not reach the customer demand.
