The invention discloses a star map recognition method and device based on a neural network and a related medium. The method comprises the following steps: selecting a primary star from a star map training image; constructing a coordinate feature vector through a Log-Polar algorithm, and obtaining a first brightness value of a primary satellite and second brightness values of other adjacent satellites; setting a relative brightness factor according to the first brightness value and the second brightness value, and mapping the relative brightness factor according to a preset brightness threshold to obtain a brightness feature vector; constructing a fixed star feature vector set according to the coordinate feature vector and the brightness feature vector, inputting the fixed star feature vector set to a neural network for training and learning, and outputting a primary star number by the neural network to construct a star map recognition model; and performing serial number prediction on the target stars by using
