Abstract

This invention relates to a wind tunnel-based system and method for analyzing pipe surface frost, belonging to the field of wind tunnel testing technology, to study the frost phenomenon on pipe surfaces and obtain the characteristics of the frost rate. In this application, a first and second field-of-view rectangle tangent to the outer surface of the pipe can be acquired in real time using a first, second, third, and fourth image acquisition device. Based on the first and second field-of-view rectangles, an octagon with each side tangent to the outer surface of the pipe is obtained, and the length of each side of the octagon is calculated. Then, the cross-sectional area and volume of the pipe are calculated based on the length of each side of the octagon to meet the analysis needs of pipe surface frost. Based on this, the frost phenomenon on the pipe surface can be studied, and the frost rate of the pipe surface can be obtained.
