The traditional method is to directly measure the human organ or the contour by using a measuring tool, and the application range of the direct measurement method is gradually reduced along with the wide application of the Internet.
The following modes are adopted for obtaining the human organ or contour parameters through the Internet:
1. the client fills in the data acquired by the direct measurement method, and the problems are as follows: the standard and unity of the measuring tool and the measuring method cannot be guaranteed, so that the accuracy of the measured data cannot be guaranteed.
2.
