Digital detection method of large-size skin based on laser tracker

The digital detection method of large-scale skin based on laser tracker firstly processes the MBD digital model of skin part with CATIA software, generates detection features, and sets feature measurement points to represent the measurement parameters on the extracted detection features; and then positioning and fixing the skin part on the fixing flat table; measuring the data of skin parts by using the testing system, analyzing software compares the measured data with the theoretical data, and then fits them to establish the functional relationship between the measured data and the theoretical data, and constructs the measuring coordinate system. Then through the detection system, according to the measurement planning document, complete the measurement data collection work of the detection project one by one; The data processing software fits and compares the measured data with the theoretical mathematical model to obtain the analysis results, and displays the product quality characteristics in the form of t
