A well-known wind power equipment manufacturer needs to conduct three-dimensional measurements of wind power blade molds 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 the 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, it is particularly important whether the quality of wind power blade molds can meet the standards.

        1. Due to the huge size of the wind power blade mold (about 20 meters long and 2 to 3 meters wide), the surface precision is high and it is inconvenient to move. When measuring with a camera-type 3D scanner, the cumulative error will be too large. How to eliminate the error caused by The impact is the biggest problem faced.

         2. The use of traditional measurement methods not only takes a long time, but the data obtained is limited and cannot accurately measure the three-dimensional data of the wind turbine blade surface, making complete scanning and data splicing impossible. It is also impossible to complete the quality inspection of wind power blade molds.

        In view of the company's large scanning area and high surface precision requirements for wind power blade molds, in order to eliminate problems such as cumulative scanning errors and complete splicing, HOLON3D technical engineers proposed a solution: using the 3D photogrammetry system HL-3DP does not require the use of a 3D scanner alone. It can complete the three-dimensional inspection of ultra-large wind power blade molds, quickly obtain high-precision three-dimensional data of the blade mold + reverse design software (convert the point cloud data of the wind power blade mold into triangular mesh surface data) + import the design software for post-processing, and obtain the inspection analysis report.
