The invention relates to the technical field of crystal growth identification, in particular to a method for identifying and detecting edge angles of a seed crystal single crystal line in a crystal growth process, which comprises the four steps of constructing a high-quality data set, constructing an artificial intelligence algorithm model, training the model and evaluating and verifying the model. The invention provides a method for automatically judging the seeding time, so that a control system automatically controls the operation of starting a seeding procedure after temperature adjustment is finished; specifically, picture data of a large batch of related scenes are trained through a deep learning algorithm to obtain an optimal model, so that the angle emergence state of the edge angle of the seed crystal single crystal line can be accurately detected, and a crystal growth control system calling the optimal model can automatically judge the starting time of a seeding process, so as to improve the accurac
