The invention discloses a rock core wire cutting method based on computer vision, which comprises the following steps: acquiring an image of a rock core to be cut, and establishing a rock core three-dimensional model through the image of the rock core; manufacturing a plunger sample three-dimensional boundary model with a corresponding size; displaying the core three-dimensional model and the plunger sample three-dimensional boundary model in the same three-dimensional coordinate system, and screening out an optimal cutting position; the three-dimensional boundary model of the plunger sample is moved to the optimal cutting position, and a cutting path is generated; and cutting the rock core according to the cutting path. The technical scheme provided by the invention has the beneficial effects that the to-be-cut rock core is firstly subjected to three-dimensional modeling, and then the three-dimensional model of the rock core is cut through the three-dimensional boundary model of the plunger ...
