Most parts of the turbine blade are complex curved surfaces, and the mode of directly detecting products by using the traditional detection tool cannot meet the increasing requirements of industrial detection. On the one hand, the traditional checking fixture has limited types and categories of parameters which can be detected, whether the complex product meets the specific design requirements or not can not be accurately and quickly judged, and on the other hand, the checking fixture can be worn after being used for a long time, and the detection result of the product can be directly influenced. The high-precision three-dimensional model of the product is obtained through three-dimensional scanning, then the model is directly compared with the design model, the deviation between the product and the design size of the product can be rapidly and accurately calculated and quantified, and whether the product is qualified or not is judged. The non-contact detection method greatly improves the quality and efficiency of the detection process.
The existing three-dimensional scanning method needs to stick a light-reflecting positioning target (a light-reflecting patch or Mark) on a detected workpiece for identifying, positioning and splicing of a three-dimensional scanner.
However, the inventor finds that the existing three-dimensional scanning method and the scanning system thereof have the following problems:
1) after three-dimensional scanning, the reflection positioning target point on the STL data is removed by processing, wherein the scanning software calculates and then compensates according to the curvature of the circumferential attachment of the reflection positioning target point of the turbine blade, and the actual curvature of the reflection positioning target point position adhered to the turbine blade has slight deviation;
2) when the existing three-dimensional scanning mode is used for batch detection, each piece of adhered light-reflecting positioning target point is easy to cause low efficiency;
3) the positions and the number of the reflecting and positioning target points pasted by different inspectors are possibly different, and the number of the three-dimensional scanning steps and the number of the fitted photos are different, so that the final scanning and forming STL data files are slightly different. In addition, moving the lens of the three-dimensional scanner to find the optimal three-dimensional photographing angle is also prone to device errors.

Because only the bottom of the fixed workpiece is shielded, and the peripheral side and the upper side are open, the three-dimensional scanning device can directly carry out three-dimensional scanning on the workpiece to be detected only by obtaining the relative relation with the rotating seat 2 for fixing the workpiece and fitting and establishing a space coordinate system without pasting a light-reflecting patch on the surface of the workpiece to be detected. Meanwhile, the reflective patch can be repeatedly used after being stuck on the rotating seat 2 for one time, so that the preparation time of the three-dimensional measurement process is simplified.
