Abstract
The blade model is a three-dimensional surface structure that uses a close-range industrial photogrammetry system to measure the blade model. This paper firstly verifies the reliability of the system detection marker point algorithm, and then analyzes the accuracy of the close-range photogrammetry system by three factors: shooting distance, number of coding points and location of the camera station. Experiments show that the shooting distance has a great influence on the calculation accuracy, while the number of coding points and camera position have a little influence. Besides, we get a better data acquisition scheme through experiments, which solve the problem that the system accuracy is easily affected by the shooting conditions, and the system accuracy is further improved.
