The invention discloses a rock mass fracture parameter acquisition method based on an elliptic model, and the method comprises the steps: obtaining a fracture image of a to-be-researched rock mass surface, and carrying out the image segmentation and enhancement processing of the fracture image; identifying the enhanced fracture image by adopting a neural network to obtain an identification result of the rock mass fracture and the trace length of the rock mass fracture; all trace length data of the rock mass to be researched are counted, a frequency distribution histogram of trace lengths is drawn, so that a distribution curve of the trace lengths is obtained through fitting, and a distribution rule of the fitted curve is determined; selecting a probability density function of trace length according to the distribution rule of the fitted curve; according to the probability density function of the trace length, respectively constructing a long axis probability density model of the long axis of the elliptical fr
