Abstract
The solar panel surface crack is a very important factor affecting its performance. Analyzing the characteristics of the solar panel surface image, detecting and annotating the crack using the min filter, the paper proposes the method of cubic parametric spline curve fitting crack which is compared with the least-squares polynomial curve fitting. The experiments show that the former has smaller fitting error and more close to real crack.
