A well-known wind power equipment manufacturer needs to measure the wind power blade mold three-dimensionally to check whether the blade mold production is qualified. Wind power blades are the most basic and critical components of wind turbines. The design of blades directly affects the conversion efficiency of wind energy and its annual power generation. Good design, reliable quality and superior performance are the decisions to ensure the normal and stable operation of the unit. factor. Therefore, the quality of wind power blade molds is particularly important.

Practical problems

1. Because the wind power blade mold is huge (about 20 meters long and about 2 to 3 meters wide), the surface accuracy is high and inconvenient to move. When measuring with a camera-type 3D scanner, the cumulative error will be too large, how to eliminate the error. The impact is the biggest problem facing.

2. The traditional measurement method not only takes a long time, but the obtained data is limited and cannot accurately measure the three-dimensional data of the wind turbine blade surface, and the complete scanning and data splicing cannot be performed. Quality inspection of wind power blade molds cannot be completed.

Holon solutions

For the enterprise, the wind power blade mold has a large scanning area and high surface precision requirements. In order to eliminate the scanning cumulative error and complete splicing, Holon 3D technical engineer proposed a solution: using the 3D photogrammetric system HL-3DP without matching the 3D scanner The three-dimensional inspection of the super-large wind blade mold can be completed separately, and the high-precision three-dimensional data of the blade mold can be quickly obtained (reverse design software for converting the wind power blade mold point cloud data into triangular mesh surface data) + imported design software for post-processing, Test analysis report.
